The modern market for roofing materials allows you to choose a coating to suit every taste and budget. And there are two very popular ones in it, seemingly similar, but completely different in essence materials - profiled metal and bitumen sheets.
They cost approximately the same, look similar from a distance, have a recognizable geometry, and therefore often confuse future home owners: where to choose? Especially considering the conflicting customer reviews.
In this case, let's take a closer look at those situations where it is more preferable ondulin or corrugated sheeting: which is better for the roof of a residential and cold attic of a house, northern or southern region, and also what exactly pleases and upsets in both types of roofing.
Corrugated sheeting and ondulin are really similar in appearance, because both are long sheets bent on a machine into a certain profile. But in terms of raw materials, both materials differ radically:
The basis for the production of ondulin is the most common waste paper, which is processed at the plant. Cardboard in the finished sheet is from 400 to 500 grams per square meter. As a result, such a mass looks like a porous material and represents fibers from recycled synthetic, textile and wood raw materials.
And not everything is as simple as many people think. There are certain quality requirements for such raw materials: there should be no lumps, cracks or tears in the cardboard. Only straight ends and a uniform layer, which can in the future ensure uniform and high-quality impregnation with molten bitumen. In addition, the cardboard must have some tensile strength and a moisture content of no more than 6%.
But corrugated sheets today are produced on the basis of cold-rolled but hot-dip galvanized steel. In production, zinc is applied to a steel sheet with a thickness of 0.14 to 1.5 mm in a layer of about 30 micrometers. Galvanizing itself reduces the cost of the material, but provides a good level of corrosion protection. The finished sheet has fairly high mechanical strength and bending rigidity.
Of course, the very comparison of cardboard and steel sounds funny. How can you even talk about something like this seriously? This is exactly what many people think and are mistaken. Indeed, in fact, cellulose is rightfully considered one of the most durable materials in existence. Look at the old wooden houses that have been standing for the second century, and they are not afraid of either wind or rain.
It's all about these flexible and durable fibers created by nature itself - cellulose. And strong wood in practice can withstand a much greater load than thin metal, like a tin can. Because it’s all about the technical characteristics of the finished product.
By the way, e There is such a subtype of corrugated sheeting as metal slate - this is also a thin profiled metal sheet, which differs only in its wavy shape. It looks more harmonious on the roof than the angular traditional metal profile, but there are still many questions about its high-quality fastening and protection against leaks. In appearance, such a roof can no longer be distinguished from ondulin from afar.
Load calculation: when strength is a priority
According to modern European slate manufacturers, their roofing covering can withstand loads of up to 960 kg per square meter. But in the case of corrugated sheeting, you will not find a clear answer anywhere, because everything depends on its brand and purpose.
The whole secret is that The height of its corrugation, unlike metal tiles, varies greatly - from 8 mm to 150 mm. And the higher the wave, the stronger the material, and the more resistant it is to deflection.
And it is precisely based on these stiffening ribs that the metal profiled sheet is divided into separate categories:
Only roofing and load-bearing corrugated sheeting are suitable for roof construction. Moreover, for example, if you want to play it safe, you won’t be able to do anything with ondulin - it always comes in the same format.
But you can purchase a corrugated sheet with a corrugation height chosen at your discretion, and provide the roof with almost any strength. After all, its load-bearing appearance is even used as a basis for covering an entire floor!
Therefore, if you are faced with the question of whether the roof of your house or the same veranda will withstand a heavy snowy winter, when your region is famous for just such a climate, then it is better to give preference to corrugated sheeting.
All elements: resistance to mechanical damage
There is also an interesting observation about ondulin: in some regions of Russia it can be damaged by woodpeckers who catch flies in the fall. There are reviews that these small-packed birds literally break through this coating. Although ondulin itself can restore its shape, such damage does not bode well.
You've also probably heard that Euro slate bends underfoot. This is partially true, and this only happens in unbearable heat of more than 40 degrees. In this case, under direct sunlight, it can soften so much that it will actually sag from a person’s foot and will not even recover.
Then the natural question is asked: why even walk on the roof in such heat? In fact, there are reasons: to fix the antenna, remove a mischievous cat, return a flying drone.
Don't forget about wind loads too. Yes, and Ondulin and corrugated sheets have similar geometric surfaces and, like solid materials, have high windage properties. But corrugated sheeting is still torn off roofs more often. Why?
The fact is that, due to this very problem, ondulin manufacturers produce special nails with wide heads and threads on the rod. The nail is driven deep into the sheathing, where it sits quite firmly, and the wide head of the fastener holds the sheets well. But with corrugated sheets, standard screws are used. And their cap is not as wide as that of ondulin.
Heat shielding: comfort of living under a roof
This is how a bitumen profiled sheet fundamentally differs from a metal one:
Bitumen is a natural resin, and ondulin has always had and will have a certain flexibility and viscosity at high temperatures. Therefore, on the hottest summer days it softens a little, which causes inconvenience, if only because walking on such a roof is temporarily not allowed. But at the same time, bitumen sheets themselves have low thermal conductivity, and therefore do not transfer heat to the under-roof space.
Thanks to this, the attic or residential attic with such a roof is cool in summer and warm in winter. The same cannot be said about a metal roof, which heats up in direct sunlight in a matter of minutes, and in winter turns into ice. At the same time, the presence of a layer of insulation under the sheets only partly solves the problem.
Protective coating: weathering
Modern ondulin on the front side of the sheet is covered with a protective and decorative paint layer based on light-resistant pigments and polymers. High-quality ondulin is also coated with high-strength acrylic, which significantly increases the durability of the sheets and protects them from weather conditions. Thanks to all this, all the dirt that gets on the roof surface can be easily removed by the first rain or sliding snow.
By the way, the surface of ondulin is rough, and therefore by itself holds a cap of snow on the roof (additional thermal insulation, by the way). But for corrugated sheeting you need to install special snow guards, and the more, the better:
As you can see, this is very close in properties to the perfectly smooth surface of a corrugated sheet, on which dirt almost never lingers.
Condensation problem: rain under the roof
And not only do the drops collect on the inner surface of the panel, but they also roll directly onto the walls. And therefore, when laying insulation, it is necessary to create a ventilation gap and provide ventilation so that all moisture leaves the roof and does not spoil the thermal insulation.
At the same time, ondulin does not heat up that much, and therefore does not condense, and there is no question of such problems. True, it softens from the sun's rays and some residents even detect the smell of bitumen.
But, in fairness, we note that there are brands of corrugated sheets that are produced with a special anti-condensation coating on the inside. This decision was literally revolutionary. The fact is that before sale, corrugated sheets often have to be stored in cold rooms, and since the metal cools faster than other materials, even from the cold air there is something to condense on its surface.
The anti-condensation coating itself is something like a pile that holds small drops on itself, preventing them from collecting into small streams. And when temperature conditions return to normal, the coating will dry on its own in the air flow:
Interestingly, the polymer film on such corrugated sheeting also protects the metal itself from negative chemical influences, of which there are many, for example, in industrial buildings.
All this is important for industrial construction. After all, the mere use of accompanying material in the form of additional boards and waterproofing increases the labor intensity of all work at least twice. As is their cost.
Until recently, condensation on corrugated sheets was dealt with using standard technological solutions. Rolled waterproofing or roofing membrane was spread over the sheathing, a gap was made, then the roof covering itself was fastened along the counter-lattice. Moisture from the air condensed on the inside of the metal sheet, then dripped onto the waterproofing and simply flowed down it if everything was done correctly.
This is a simple physical phenomenon: there is always water vapor in the air, and when heated, it comes into contact with a colder surface and simply cools down, turning into droplets, at a moment called the dew point. Moreover, this process occurs every day, every night. Considering that during the day the metal roof is heated by the sun and heats the air under it.
If it now seems to you that corrugated sheeting is definitely inferior to ondulin, let’s honestly and impartially consider the important disadvantages of the latter:
Let us add the following observation regarding color fading. G After a year or two, glossy ondulin becomes beautifully matte, lighter in tone, and most buyers even like it.
Transportation and installation: pitfalls
Ondulin is quite easy to transport due to its light weight (up to 6 kg). You've probably seen a stack of bitumen sheets on the roof of a car or in the trunk. But, due to the fact that ondulin can be bent, putting it in the trunk will not be a problem, but corrugated sheeting can only be transported on the roof of a car, or even using special transport.
Further, if it is difficult to scratch ondulin sheets during loading and unloading, then the corrugated sheeting can begin to rust from the slightest damage. What is the disadvantage of corrugated sheeting? In the process of transporting parts to the construction site, you literally have to shake over metal sheets.
After all, even if you then treat the scratches with paint or sealant, it will become noticeable and the original appearance of the roof will be lost. That’s why such sheets are also lifted onto the roof with extreme caution.But you can even throw ondulin onto low buildings by hand.
Unfortunately, some of the typical problems with corrugated sheets arise even before installation:
Installation Features: Geometry Problems
There is a significant difference in the installation of corrugated sheeting and ondulin. Thus, ondulin can be laid on roofs with a slope of at least 14 degrees. But corrugated sheeting, depending on the height of its corrugation, is even suitable for constructing a load-bearing floor for a house. To some extent, certain types of corrugated sheeting are much more durable and stronger than ondulin (which cannot be said about metal tiles).
When the roof is perfectly flat, both bitumen and metal profiles will look decent on it. But if it turns out that the slopes are not even rectangles, then things are bad.
To check this, you do not need to make cuts in the eaves and gable boards. It is enough to measure the diagonals, and they should match. If it turns out that one diagonal is larger than the other, you have problems.
After all, metal sheets, unlike bitumen sheets, cannot be stretched, compressed, or “pulled” to the desired location. You will have to sacrifice another sheet to cut out two triangles from it, and place each on the sides of the slope - where it will be empty and where the error in the rafter system will be clearly visible. What the roof will look like after this is another question.
But with ondulin, these problems can be easily solved with your own hands:
By the way, ondulin is quite flexible and by itself slightly eliminates the problem of sloppy sheathing. But don’t let this reassure you, because we are still talking about building a roof. At the same time, with corrugated sheeting, any error will be clearly visible.
This suggests that even an unqualified builder is able to cover a roof with ondulin quite efficiently, just by carefully studying the instructions and advice on our website. This is an important point, because there really aren’t that many trained, experienced roofers. And the more complex the installation technology, the higher the risk that it will be messed up.
Let's also consider such an important point as cutting roofing sheets. You still need to try hard to ruin an ondulin roof, and you can even cut bitumen sheets with an ordinary stationery knife. The only thing is that you can cut Euro slate in the summer only in the morning or evening so as not to soften it.
But cutting sheets of corrugated sheets in an open area is not a difficult task. True, if you do this in direct sunlight, the metal will heat up to an unpleasant temperature, giving harsh radiation directly to working people.
One of the most pressing problems is mounting the fastener. It only takes a little extra force to damage the rubber gasket on the screw. But in the case of bituminous material, you can safely work with a hammer - the base is soft and pliable, and the edges of the cap are more likely to slightly bend it than to deform themselves:
This is an important point. After all, it is precisely because of small jambs in the installation of corrugated sheeting that 99% of problems arise with it in the future: it corrodes, leaks and loses its appearance!
You should also take into account the fact that, if necessary, the corrugated roof can be carefully dismantled and moved to a new location. But in the case of ondulin, you will have to throw it away, because... the nails in it, of course, can be pulled out, but the appearance of the ondulin itself will not be the same - there will be torn holes in the places after fastening.
In total, the manufacturer of ondulin, like corrugated sheeting, produces all the necessary additional elements for the roof.
Which material did you like best? Tell us about your choice!
Choosing a roofing covering is an important step in building a house, because the lifespan and ease of use of the roof depend on the correct choice. When choosing a roofing material, preference is often given to inexpensive and popular types of covering, such as profiled metal sheets or Euro slate. At the same time, the question often arises: what is better – ondulin or corrugated sheeting? In order to make a wise choice, it is necessary to consider the characteristics of these materials and their features.
What is ondulin?
Ondulin, or Euroslate, is wavy sheets of thick cardboard impregnated with bitumen under high pressure. It is flexible and quite lightweight - the weight of one sheet does not exceed 7 kg, while the impregnation provides excellent protection from moisture. Ondulin comes in several standard colors, its surface is slightly rough and velvety to the touch. It is a soft material that can be easily cut to size, drilled and nailed, making it easy and quick to install.
In operation, ondulin has a number of advantages:
- Low price and long service life (25-50 years);
- Lightweight material that does not require continuous sheathing. Does not weigh down buildings, unlike traditional slate;
- Due to ease of processing and flexibility, it can be used to cover roofs of complex shapes with valleys, abutments, and turrets;
- Easily withstands snow loads up to 0.5 meters thick;
- Has excellent noise absorption;
- Not subject to corrosion or damage by microorganisms;
- It warms up and freezes quite slowly, so it does not form condensation or ice;
- Environmentally friendly material, does not contain asbestos.
However, in addition to its advantages, ondulin has a number of disadvantages:
- Fire hazardous. Bitumen impregnation is highly flammable and supports combustion;
- It fades in the sun over several years and changes color;
- The rough surface retains dust, debris, and snow in winter, and therefore requires periodic cleaning;
- On the north side of roofs, in damp places it is often covered with moss and lichens;
- It softens in the sun and becomes brittle in the cold, so ondulin cannot be installed or exposed to stress in hot or cold weather;
- On the Russian market there are often counterfeits of ondulin that lose their performance within two to three years.
What is corrugated sheeting?
Roofing corrugated sheets are galvanized metal sheets with a wavy cross-section, coated with protective varnish or polymer paint. Corrugated sheeting has a different profile, wave height, and thickness of the material itself. The width of the sheet is usually about a meter, and the manufacturer cuts the length into standard sheets of 6 meters or according to the length of the slope to order. The weight of a square meter of material is from 5 to 8 kg. The corrugated sheeting is secured to the roof using special self-tapping screws with a sealing washer.
The advantages of corrugated sheets include:
- Low price, service life - up to 50 years;
- Absolutely non-flammable, which is important for houses with stove heating, fireplaces, and for covering the roof of bathhouses;
- Does not require reinforced sheathing, it is enough to lay the boards in increments of 0.3-0.5 meters;
- When ordering sheet length according to the size of the slope, the number of joints is minimal;
- Thanks to the wavy profile, it can easily withstand not only the snow load, but also the weight of the human body. Strength does not decrease in heat and cold. Therefore, installation can be done at any time of the year;
- The surface of the corrugated sheet is absolutely smooth, so it does not retain snow, debris and water;
- Corrugated sheeting does not fade, is not subject to corrosion while maintaining the integrity of the coating;
- Eco-friendly material, does not contain harmful substances.
Disadvantages of corrugated sheets:
- Low level of noise absorption. Raindrops or hail can be heard not only in the attic, but also in the upper floor. If the corrugated sheeting is poorly fastened to the sheathing, the material may bend in strong winds, accompanied by an unpleasant sound;
- Due to the possible formation of condensation or ice in houses with an attic floor, mandatory roof insulation is required;
- In hot weather it gets very hot, which worsens the microclimate of the upper floor;
If the coating is severely damaged, corrosion may occur.
Fastening corrugated sheets is an easy procedure
What is better – ondulin or corrugated sheeting?
Taking into account the given characteristics and features, you can compare these roofing coverings and select the most important parameters. The service life and price of these materials are approximately the same, and these roofing coverings are also absolutely environmentally friendly, so the choice should be made depending on the installation and operating conditions.
- Fire hazard. Ondulin is flammable, corrugated sheeting is not. For homes with stove heating, corrugated sheeting will provide better protection against sparks.
- Ease of installation. Corrugated sheeting can be ordered in any size; ondulin has standard sheet sizes. Ondulin is flexible and easy to cut; corrugated sheeting on an irregularly shaped roof is much more difficult to lay. Therefore, for simple roofs with a slope length of no more than 12 meters, corrugated sheeting is more convenient; for roofs of complex shapes or with a large slope angle, it is better to choose ondulin.
- Noise absorption. Ondulin, unlike corrugated sheeting, does not conduct sound of falling drops, hail or wind well. For houses with an attic floor, as well as in regions with frequent downpours, hail and strong winds, ondulin is more convenient.
- Maintaining appearance. Corrugated sheeting does not fade in the sun; after a few years, ondulin changes its color and becomes faded. Therefore, in hot areas with a lot of sunny days, corrugated board will retain its appearance longer. In addition, the color of corrugated sheeting can be easily refreshed by painting it.
- Need for cleaning. Ondulin is susceptible to overgrowing with moss and dust. In winter, snow quickly sticks to the surface of ondulin and is difficult to remove; it must be cleaned. The corrugated sheet is smooth, all dust and debris come off it along with precipitation, so it does not require cleaning. This is especially convenient for houses with several floors, where cleaning the roof involves the danger of falling from a great height.
What exactly to choose, ondulin or corrugated sheeting, depends on local conditions, layout, number of floors and location of the house. The above comparative analysis will help you choose the right roofing material, making the best use of the advantages and eliminating the disadvantages of the coating.
A responsible task is the choice of roofing material for the roof of a living space. It is important to understand that the service life of the roof and ease of installation will directly depend on the correctness of the decision made. As practice shows, when making a purchasing decision, preference is given to inexpensive and popular roofing materials. Quite often they use ondulin and corrugated sheets. In order to understand whether ondulin or corrugated sheeting is better for the roof, it is recommended to first study the technical characteristics of the finished product - this is the only way to make the right decision.
What are ondulin and corrugated sheets
Before you start choosing a material for roofing, it is recommended to understand what ondulin and corrugated sheeting are and what advantages these roofing materials have.
Ondulin (or, as it is also called, Euroslate) is a wavy material made of cardboard and treated with special compositions based on bitumen under high pressure. As practice shows, the peculiarity of ondulin is its low weight and high level of flexibility. The weight of the sheet does not exceed 7 kg; thanks to the bitumen impregnation, moisture is not a problem during the operation of the finished product. On the market for goods and services, you can purchase roofing material in several colors; the surface is rough and slightly velvety. Since ondulin is quite soft, it is easy to cut it and make holes for fasteners, which allows installation work to be carried out in a short period of time without much effort.
If we consider the advantages of this roofing material, we can highlight the following points:
- reasonable cost;
- service life varies from 25 to 50 years;
- due to its light weight, a continuous sheathing is not required; in addition, the load on the structure is minimal;
- since the material is quite light and bends well, it can be used for arranging roofs of any configuration, including those with turrets;
- perfectly withstands the load of snow about 0.5 m thick;
- has a high level of noise absorption;
- no microorganisms appear during operation, the material is not subject to corrosion;
- due to the fact that the heating and freezing process is quite slow, ice and condensation do not form during operation;
- the material is considered environmentally friendly and does not contain asbestos fibers.
Despite such a wide list of advantages, there are some disadvantages. Thus, ondulin has the following disadvantages:
- since the production process uses bitumen-based impregnation, the material can quite easily be subject to combustion;
- over several years, finished products may fade when exposed to direct sunlight and lose their original color;
- since the surface is rough, dust, debris, and snow are perfectly retained on it, as a result of which the roof has to be cleaned regularly;
- on the north side and in damp places, moss and lichens may appear over time;
- under the influence of direct sunlight, ondulin becomes quite soft, and at low temperatures it becomes fragile, which is why many experts do not recommend carrying out installation work in hot and cold weather.
When choosing, you should be extremely careful, since there is a high probability of purchasing fake ondulin, the service life of which does not exceed 2 years.
Corrugated sheeting is a roofing material made of galvanized metal sheets with a wavy cross-section. During the production process, corrugated sheets are coated with a protective varnish or polymer coloring composition. Corrugated sheeting may differ in a number of ways: wave height, profile, thickness. Corrugated sheeting is produced with a width of about 1 m, the standard length is 6 m. Weight can range from 5 to 8 kg per square meter. m. Fastening, as practice shows, is carried out using self-tapping screws, complete with sealing washers.
Among the advantages of corrugated roofing, the following points can be noted:
- reasonable cost of finished products;
- service life is 50 years;
- not subject to combustion, as a result of which it is suitable for the roofs of those houses that have fireplaces or stove heating;
- there is no need to install reinforced sheathing on the roof; the pitch between the boards can vary from 0.3 to 0.5 m;
- if you order sheets in accordance with the dimensions of the roof slope, then the number of joints will be minimal;
- due to the fact that the material is wavy, corrugated sheeting can easily withstand heavy loads - snow, human weight, the level of strength does not change depending on temperature conditions, as a result of which installation work on the roof can be completed at any time;
- since the surface is smooth, snow, dust, and water do not linger on a roof made of corrugated sheeting;
- during operation, the finished product does not fade, and corrosion does not appear;
- The material is considered environmentally friendly and contains no harmful components.
Among the disadvantages are:
- a rather low level of sound absorption, as a result of which noise will be heard in the house during rain;
- if the material is loosely fastened, then during strong gusts of wind the corrugated sheeting may begin to bend;
- During operation, ice and condensation may appear, so it is necessary to insulate the roof;
- Since at high temperatures the corrugated roofing is subject to heating, the microclimate on the upper floor suffers significantly.
It is worth taking into account the fact that if the roofing material is quite damaged, then the appearance of corrosion cannot be avoided.
Advice! If necessary, corrugated sheeting can be cut into pieces of the required length.
Which is better – ondulin or corrugated sheet
As practice shows, it is quite difficult to give a definite answer to the question of which is better: ondulin or corrugated sheeting. In this case, much depends on the taste preferences of the potential consumer who wants to receive roofing material that meets certain criteria. In order to make the right choice in favor of a specific product, it is recommended to first compare the building material according to a number of technical characteristics, and then make a purchasing decision.
According to performance properties
If we take into account the fact that ondulin and corrugated sheeting are considered environmentally friendly materials and have the same service life, then in this case it is recommended to compare finished products according to other parameters, namely, operational properties:
- Fire safety. In this case, it is worth understanding that ondulin can ignite quite quickly, while corrugated sheets are not subject to combustion. An excellent option for the roof of a house with stove heating would be the second option.
- Convenience of installation work. If necessary, you can order corrugated sheeting for a roof of any size, but ondulin has standard sheet dimensions. A distinctive feature is the fact that ondulin is a fairly soft material, it bends well, which allows it to be cut. Thus, if the roof slope does not exceed 12 m, then it is best to use corrugated sheeting, and if the roof has a complex shape, then it is best to give preference to ondulin.
- Noise absorption. Ondulin, unlike corrugated sheeting, conducts sound rather poorly, making this option excellent for attics.
- Appearance. During operation, corrugated sheeting is not subject to fading when exposed to direct sunlight, which is why this type of roofing material retains its attractive appearance much longer. If necessary, the material can be coated with a layer of coloring composition.
- The need to regularly clean the roof. During operation, moss may appear on the ondulin, and since the surface is rough, dust and dirt are constantly retained on it. Snow that sticks to the material is quite problematic to remove in the future. Since corrugated sheeting is relatively smooth, dust and debris can be removed from the surface during precipitation; there is no need to clean this type of roofing material. This option is perfect in cases where it is planned to build a house with several floors.
As practice shows, the choice depends entirely on the weather conditions in a particular region, the layout of the building, the number of floors and the location of the building. Through careful analysis, you can make the right choice.
For ease of installation
During installation of both ondulin and corrugated sheeting, certain skills are required. In the process of attaching material to the roof, there are some features and nuances that must be taken into account.
Ondulin is quite easy to process; if necessary, it can be cut using a hacksaw for this purpose, and it can be pierced with nails. Due to the fact that the material bends quite easily, it can be used for arranging roofs of any complexity. Installation work is recommended to be carried out in warm weather, but not in the heat. The temperature regime in this case can vary from -5 °C to +30 °C.
Since ondulin requires fairly frequent lathing, large investments are required to prepare the roof base. The manufacturer recommends making the sheathing in increments of 65 cm, if the angle of inclination is 15 degrees or more; in the case when the angle of inclination is less than 15 degrees, the sheathing increment is reduced to 45 cm.
You can install a roof made of corrugated sheets at any time, regardless of weather conditions. This is due to the fact that the level of strength does not depend on temperature conditions. If necessary, you can purchase roof sheets of the required length or make an individual order, due to which the number of joints will be much smaller.
During installation work, it is not recommended to bend metal sheets, as there is a high probability that the protective coating will be damaged. Thus, this material is best used for flat roofs. If the roof is of a non-standard shape, then you may encounter problems.
By appearance
If we take into account the fact that corrugated sheeting has a big difference in the price range, then first you can compare roofing materials in appearance in the same price category. The most budget option for corrugated sheeting is a galvanized metal sheet with a matte gray surface. Ondulin is presented in a wide range of products regarding the color palette. That is why we can conclude that ondulin and corrugated sheeting in the same price category will differ greatly in appearance - the first option of roofing material for the roof will be much more attractive.
The situation is different with corrugated sheets, which are painted using polymer compounds. In this case, the roofing material will have an attractive appearance, but its cost will be much higher - several times. However, in this case, you should not forget user reviews. Many who have already been lucky enough to appreciate all the benefits of corrugated sheeting argue that painted options are completely unsuitable for the harsh Russian climatic conditions. All this leads to the fact that during operation, some painted fragments may begin to peel off.
By service life
When constructing a residential building, durability always comes first. As practice shows, the service life depends on a large number of factors, including the quality of the chosen building material for arranging the roof of a building. Therefore, before deciding what to choose, ondulin or corrugated sheeting, it is recommended to first take into account the operational service life of each product.
According to many manufacturers, the service life of ondulin can vary from 40 to 50 years. However, there is some note according to which the service life of the roofing material is only 15 years in terms of water resistance. Potential clients tend to wonder how they can live in a building for 25 or 30 years if the roof leaks. If we take into account the reviews, we can note that leaks are observed after 10 years; it is this figure that is recommended to be guided by if you plan to use ondulin for arranging the roof.
If we consider the service life of corrugated sheeting, it can vary from 25 to 30 years, but in fact the roofing material can be used much longer - up to 50 years or more. It is important to treat the protective coating made of polymer with the utmost care during delivery of finished products and installation work. Many consumers claim that even if corrosion appears on the damaged section of the corrugated sheet, there will be no leaks for a long time.
Attention! The service life of corrugated sheeting is much longer than that of ondulin.
Which is cheaper – corrugated sheeting or ondulin
The cost of roofing material is one of the most important items that many consumers consider at the very beginning. And this is not surprising, because everyone wants to purchase high-quality building materials at an affordable price.
If we consider what exactly will cost less during the installation process - ondulin or corrugated sheeting, it is worth taking into account the fact that every square meter. m of ondulin, the price varies from 200 to 250 rubles. This indicator exceeds the cost of the well-known asbestos-cement slate by only 30%. As practice shows, this excess in cost is fully justified by the large number of advantages that the roofing material has.
Corrugated sheeting can vary in cost over a much wider range. Thus, the price of 1 sq. m can start from 300-350 and end at around 500 rubles, in some cases the price can be even higher. As practice and reviews from many experts show, profiled sheets can be in different price categories, but the quality always remains at the proper level. That is why it is recommended to stop at the lower price level.
Important! As it becomes clear, the price of corrugated sheeting will be much higher than purchasing ondulin. However, it is important to understand that such a difference can quite easily be compensated for by a number of parameters: long service life, high level of strength.
How to make the right choice
It is impossible to give a definite answer as to which material is better - ondulin or corrugated sheeting. Even experienced roofers say that in this case the choice depends entirely on the personal preferences of the owner of the residential premises. It is important to understand that each roofing material intended for arranging a roof has a number of advantages and disadvantages that must be taken into account by the potential consumer before making a purchase.
If you take into account the technical characteristics when choosing between ondulin and corrugated sheeting, then in this case it can be noted that both types of roofing materials are environmentally friendly, they are not capable of causing harm to humans, and have the same service life. In terms of cost, corrugated roofing will be cheaper. If we take into account the fact that even the most budget version of corrugated sheeting has the same technical parameters as products that are several times more expensive, then in terms of cost you can stop at the lowest point, as a result of which the difference in cost will be insignificant.
In order to purchase truly high-quality material, many experts recommend purchasing from reliable suppliers, while giving preference to well-known manufacturers. This is the only way to obtain high-quality finished products that will meet all the declared parameters and technical specifications.
Conclusion
Ondulin or corrugated sheeting is better for the roof - a rather controversial point. It is problematic to answer this question, since the choice depends on the personal preferences and taste of the potential consumer. But before making a purchase, it is recommended to carefully study all the advantages and disadvantages of roofing materials. Then a high-quality roof will serve for a long time and protect the comfort and peace of the inhabitants of the house.
620 09/18/2019 5 min.The roofing material must be reliable, moisture-repellent and have a beautiful appearance. It is desirable that it can be easily laid, and if necessary, it is possible to replace only one deformed section, and not the entire roof.
Modern roofing materials such as ondulin and corrugated sheets meet these requirements. The question often arises, which one is better to choose; without familiarizing yourself with their advantages and disadvantages, it is difficult to understand. To make the choice easier, we will provide a comprehensive answer to this question.
Pros and cons of corrugated sheets
It is a sheet of metal that has increased rigidity. It is based on sheets of galvanized steel, the wave-shaped profile of which is made on rolling equipment. Its sheets are coated with a protective anti-corrosion compound, then a layer of primer is applied. Varnish is applied to the outside of the material, and polymer is applied to the inside.
The rigidity of the corrugated sheet is ensured by trapezoidal ribs. The material is used not only for roofs, but also for arranging fences and walls of buildings.
It has found such a wide range of applications due to its positive aspects:
- Light weight, facilitating installation work.
- Affordable price.
- Durability. If the protective layer remains intact during its stay on the roof, the material can last for half a century.
- Environmentally friendly.
- A small number of material joints ensures high tightness of the entire roof.
- Wide range of colors.
- High fire safety. Corrugated sheeting is not flammable and does not support fire.
- Protection from rot and corrosion.
- Versatility. Corrugated sheeting can be mounted on roofs of any complexity and slope. It is used for buildings for various purposes.
- Beautiful appearance.

The disadvantages of corrugated sheets include:
- Formation of condensation on the surface of the material.
- Low degree of sound insulation, which threatens the presence of noise during precipitation.
- Roofs with curves and complex angles can cause problems.

Pros and cons of ondulin
This material is also called Euro slate; it quickly won its admirers; many prefer it because of its aesthetic appearance. A roof covered with it looks attractive; its wavy sheets, imitating classic slate, add harmony. It was invented more than 50 years ago for residential buildings; it is used to cover canopies, gazebos, and private cottages. It makes any building look solid.
Its production uses cellulose fibers, which are pressed and then impregnated with bitumen. Afterwards, the manufactured sheets are given a wavy shape. They are covered with paint and resin on top.
Due to the small thickness of the sheet, this material is relatively lightweight, which makes it easier to transport and lift to the roof of the building. In addition, due to this, ondulin can be cut with a regular hacksaw; it bends perfectly, so it can be used for roofing surfaces of any complexity.
Due to its positive properties, ondulin can compete even with tiles; its strengths include:
Like any other material, ondulin has its downsides:
What's better?
Each of the materials considered is good for roofing, even with its drawbacks. The choice of one of them is primarily based on the preferences of the owner of the house. But there are several nuances of these materials, if you compare them according to certain characteristics.
Ondulin can only be used for roofs, while corrugated sheeting has a more diverse application. A roof and a fence made from it in its native color will look very interesting in one area. But what is better is ondulin or metal tiles, this information will help you understand in detail. But what is better to cover the roof with corrugated sheets or metal tiles?
On the video, what is cheaper ondulin or corrugated sheeting:
Ondulin differs from corrugated sheeting in its greater plasticity, so it is better to prefer it for complex roof structures; it is excellent for fastening in various hard-to-reach places. There is no need to make a continuous sheathing underneath, as is the case with corrugated sheeting; it has higher heat and sound insulation properties. But galvanized material is not subject to combustion and ultraviolet radiation, it is more airtight, but is susceptible to corrosion at the attachment points.
The cost and service life of ondulin and corrugated sheets are the same, the weight of their sheets is practically the same.
When choosing between these two roofing materials, the main thing is to take into account the features of the structure being built, the degree of complexity of its roof, the presence of an attic floor in the house and the structures located near it. Durability and performance properties are guaranteed only by high-quality materials, so when purchasing them you need to check for a certificate.
The construction industry offers a wide range of different roofing materials. When choosing a budget roof covering, they most often compare corrugated sheeting and ondulin. These materials are not expensive, are lightweight and easy to install. Although similar in many ways, they still have significant differences.
Corrugated sheets are made from galvanized sheet steel with a protective polymer coating. Ondulin is made from a whole composition of materials, which includes cellulose fibers, bitumen-based additives, hardener resins, mineral components and dyes.
Criterias of choice
Appearance
The roof is the second “face” of the building after the facade. The appearance of the roof plays an important role in the attractiveness of a building, especially a low-rise one. Ondulin always has a standard waveform and only 4 possible colors: red, green, brown and slate (black).
Corrugated sheeting is ahead of its competitor in this criterion. The material can have different shapes and wave heights, and can also be painted in one of dozens of colors from the RAL palette.

Life time
How long the roofing material will last largely depends on the raw materials and production technology. To do this, you need to pay attention to the following characteristics:
- Steel grade and thickness of the finished sheet;
- Amount of zinc (the more, the better the corrosion protection);
- Type of protective coating (plastisol, pural, polyester and others). Each polymer has its own unique properties and characteristics.
The service life of a roof made of corrugated sheets, depending on the material chosen, ranges from 10 to 35 years or more.
The manufacturer Ondulin guarantees water resistance for 15 years. The material is more “sensitive” to installation errors and weather conditions in the region (frost increases the fragility of the material, and in sultry, hot weather an unpleasant odor of bitumen appears).
Transportation
This criterion is important for those who are going to carry out work far from the place of sale/production of roofing materials.
1 sq. m of corrugated sheeting with a thickness of 0.5 mm weighs approximately 5.5 kg. In production, you can order sheets of the required size according to the size of the slope, but you need to take into account that transporting them will require a truck with a long side.
Operation and Maintenance
Ondulin sheets have a rough surface on which moss and lichen can begin to grow. If the house is located on a site near a forest, debris from leaves and small branches will accumulate on the roof. The owner will have to regularly clean the roof or order this service for money.
Corrugated sheeting has its drawbacks; it makes noise during rain and hail. In addition, the metal gets very hot in the sun. Therefore, for a house with an attic you will need to make the right one with an insulating layer of mineral wool.
It is worth noting that corrugated sheeting retains its aesthetic qualities throughout its entire service life, while Ondulin gradually fades in the sun, losing its original color.
Price per sq. m
Cost of 1 sq. m Ondulina averages 250 rubles.
Price per 1 sq. m of corrugated sheeting starts from 250 rubles. - This is a simple galvanized sheet. Premium class products from the manufacturer GrandLine with a 35-year guarantee made from imported steel with a polymer coating will cost from 850 rubles. for 1 sq. m.

conclusions
Corrugated sheeting is a stronger and more durable material. It can be used for private houses and outbuildings with a simple roof shape, or for covering roofs in areas with difficult climatic conditions: severe frosts or temperatures above 30°C.
Ondulin is perfect for use in regions with high humidity and strong winds. But it does not tolerate prolonged exposure to high and low temperatures. Not suitable for roofs with increased fire safety requirements.
