What is better slate or metal profile. What is better slate or metal tile

Any house is covered with a roof to protect from the weather. For thousands of years, people have been improving the design of the roof of the house, covering their homes with more advanced materials. From what they just did not try to make roofing material! Ceramics, slate, vegetable fibres, metal, bitumen, plastic, concrete…

At the end of the 19th century, roofing material was invented - the first soft roofing material that began to be produced on an industrial scale. The principle of its production is impregnation fibrous materials resin - is still used to obtain modern soft roofing materials.

The name of this material, produced by the company of the same name, is known to many people, even those who have nothing to do with construction. It is also called euroslate or bituminous slate. It is one of the most widespread modern soft roofs ny materials. They cover houses in many countries on different continents. Let's try to understand its properties and compare it with other roofing materials.

From what and how is ondulin produced? The raw material for the production of ondulin is natural cellulose fiber which is obtained from waste paper. First, the waste paper is cleaned of debris and soaked, turning into paper pulp (pulp). A dye is added to the pulp, giving color finished material. Next, the pulp is sent to a machine in which a corrugated sheet is formed. This sheet is dried and then sent to the impregnation department, where it is impregnated with bituminous resin under pressure and heating. Since the resin impregnates the mass after dyeing, the color of the sheet is retained for a long time. This is what distinguishes original material from fakes.

The finished material is packed with shrink film in pallets. The material is stored in pallets and delivered to the consumer.

Composition of ondulin.

Although the technology for the production of ondulin is not much different from the technology for the production of roofing felt, there are some differences in the composition of the material that significantly affect its properties. The main components of the composition are as follows:

cellulose fibers;
purified bituminous resin;
mineral fillers;
synthetic resin.

Thanks to additional components, the roof of this material heats up sunbeams much less than a roof made of ruberoid. Synthetic resin makes the material stronger and harder, its softening temperature is significantly increased. Substances that reduce the combustibility of the material are also added to the composition.

Ondulin properties.

Since ondulin is a rather hard material, it is not produced in rolls, like roofing material, but in the form of corrugated sheets. One such corrugated sheet 2000 mm long, 950 mm wide and 3 mm thick weighs approximately 6.5 kg. In other words, this material is one of the lightest among roofing materials (3.4 kg/m²). To destroy the roof of this material, you need to create a pressure of more than 960 kgf / m². At the same time, the sheet of material itself only bends, and the crate and rafters break. This happens if the roof is going a large number of snow.

Due to changes in the composition of the material, its resistance to heating by sunlight has increased. So, ondulin sheets remain elastic, retaining their shape up to 110 ° C. Soundproof properties are also not bad: when sound passes through a sheet, its intensity drops by 40 decibels.

To assess the resistance of roofing materials to temperature fluctuations, they are subjected to repeated freezing and thawing. Ondulin withstands 25 cycles of such tests without changing its structure and appearance.

However, in order to objectively assess the advantages and disadvantages of any material, it must be compared with others.
Let's try to compare ondulin with other roofing materials and determine its scope.

Which is better, ondulin or metal tile.

If ondulin has been used in Russia recently (about 15 years), then metal tiles have been used for more than 20 years. Thus, its properties are already known not only in theory, but also in practice.

Advantages of a metal tile in comparison with ondulin:

Ease. Weight 1 sq. m metal tiles about 5 kg. This is about 2.5 times less than that of slate, but in comparison with ondulin (3.4 kg / m²), the metal tile loses. One way or another, under both of these materials, a powerful truss system is not needed, which saves money.
Durability. The metal tile of the European quality serves from 25 to 50 years. The manufacturer of ondulin gives a guarantee of 15 years, although it can serve up to 40 years (according to European practice). Thus, in this parameter, ondulin is inferior to a metal tile.
Simplicity of laying technology. The metal tile is mounted quickly enough and without large labor costs, but it requires special tools for cutting (nibblers, hacksaw, electric jigsaw) and protection of the cut from corrosion. Self-tapping screws in the metal tile must be screwed with a screwdriver. Ondulin can be cut sharp knife, and it is fastened with nails with a hammer. No other tools are needed.
Beautiful appearance. Metal tiles are produced different colors and shades that do not change over time. Ondulin is also available in multi-colored, but the choice of colors is limited.
Resistance to temperature fluctuations. The metal tile well maintains temperature fluctuations for many years. Ondulin is also resistant to temperature fluctuations, but with high temperatures it softens, and in the cold it becomes brittle, therefore, such a coating cannot be repaired either in the heat or in the cold.
Damage resistance. Both materials withstand the pressure of snow and the impact of falling branches or stones quite well. A slightly damaged sheet of metal tiles can be easily painted over with paint, and in case of significant damage, replace the sheet with a new one. In the same way, you can replace the ondulin sheet.
Fire safety. The metal does not burn and does not support combustion. As for ondulin, it lights up at a temperature of 230–300 ° C.

Disadvantages of metal tiles compared to ondulin:

Insufficient soundproofing. Metal makes a loud thud when hit by hailstones and raindrops. This disadvantage can be eliminated with the help of fibrous insulation. Ondulin, due to its elasticity, dampens the sounds of impacts well, and weakens street noise.
The metal tile easily gives off heat, therefore, it requires reliable thermal insulation of the roof. Ondulin retains heat better, but roof insulation is still required.
The cost of metal tiles is very high. Ondulin is much cheaper, although it has to be changed more often, it can be laid on top of the old layer. The metal tile during repair needs to be removed and replaced.

Which is better, ondulin or corrugated board?

Decking - corrugated (profiled) steel sheet coated with zinc or aluzinc, as well as polymers on both sides. This material is also used as a modern roofing material. Its protective coating system is approximately the same as that of a metal tile. Let's try to compare it with ondulin.

Advantages of corrugated board in comparison with ondulin:

Decking from different companies is slightly cheaper than metal tiles High Quality. However, in comparison with ondulin, it loses significantly in this indicator.
The service life of corrugated board is the same as that of metal tiles, and reaches 50 years if the protective coatings are not damaged. Ondulin can serve in best case 40 years, which means that according to this indicator he is inferior.
Decking is an almost universal roof covering. It is suitable for various types roofs. However, such a roof weighs about the same as a metal tile. It should be noted that the corrugated board is mounted in sheets of large sizes, trying to cut it less. This is both good and bad: fewer joints, higher labor productivity, but working with long sheets is harder. Work with light sheets ondulin is much simpler. It is necessary to cut sheets of corrugated board in the same way as metal tiles special tools, protecting sections from corrosion, and ondulin is well cut with a knife and is not subject to corrosion.
Fire resistance. According to this indicator, ondulin, of course, is inferior to corrugated board, as well as metal tiles.

Minuses:

Soundproofing. Decking is the same "loud" roofing material as metal tiles. Eliminate this drawback in the same way - a lining of fibrous insulation.
Decking is difficult to use if the roof complex shape. Ondulin is a more elastic material. It is easy to bend along the wave with a bend radius of 5 m or more, so it has an advantage here.

Which is better, Slate or Ondulin.

Well-known since Soviet times, slate is still a popular roofing material. Its advantages and disadvantages are known to us very well. Let's try and compare it with ondulin.

Slate properties when compared with ondulin:

Price. Slate is the cheapest roofing material after roofing material. In this, ondulin, of course, is inferior to him, although not by much.
Ease of installation. Slate is one of the heaviest materials. In this he is hopelessly inferior to almost all materials. In addition, slate is very fragile. Holes for nails for its fastening have to be drilled, otherwise it will crack when punched with a nail. It is necessary to cut slate sheets with a grinder with a cutting wheel for working with stone, be sure to water it with water so that dust does not form. All this complicates its installation. There are no such problems with ondulin. It is cut with a knife and nailed.

Durability. Manufacturers give a guarantee for slate for 15 years, and it serves 40 years or more. In this respect, the materials are equal.
The slate bears the load well under the pressure of a thick layer of snow. Ondulin is not inferior to him in this. But upon impact, the elastic ondulin withstands, and the slate cracks.
Slate does not burn unlike ondulin. But in the event of a fire, the slate roof crumbles with a deafening crash.
During rain and hail, slate muffles sounds, like ondulin.

Roofing manufacturers around the world are constantly looking for the most economical solutions. Thanks to innovative technologies and development, modern market Roofing materials are so replete with materials that not only an ordinary buyer, sometimes a specialist, it is easy to get confused. V Lately In Russia, metal tiles are gaining more and more popularity. In our article, we will talk about which roofing material: slate, corrugated board or metal tiles to give preference to; which metal tile is better.

Recall that on how you choose the right material for the roof, how you calculate its design, its further operation and durability depend. And this, in turn, will affect the quality of operation of the entire building.

Before answering the question: metal tile - which is better? Consider brief characteristics the most popular roofing materials.

So, the long-liver among roofing is slate. Since ancient times, we remember the gray coating of the same type as the most common (at that time there was simply no choice), which had no competitors.

Slate is wavy asbestos-cement sheets. Currently, manufacturers produce slate of different colors and colors, its weight has decreased significantly.

Modern manufacturers offer three types of slate:

With uniform coverage.
with a regular profile.
with reinforced profile.

The main advantages of slate:

Non-combustible.
It has high thermal insulation properties.
The material is heat resistant.
Perfectly cut into the necessary details.
It will withstand even the highest load.
Ease of installation.
Environmental friendliness.

The disadvantages of slate include the following qualities:

The material does not bend, so it can be used on roofs, the design of which has only even corners.
The slope should have an angle greater than 45 degrees, as the slate has an impressive weight.

We hope that knowing the advantages and disadvantages of slate, you will be able to decide which roofing material for the roof of your house is better: slate or metal tile.

Characteristics of corrugated board, its advantages and disadvantages

Consider the characteristics of another, no less popular, material for roofing and other works - corrugated board, in order to decide which is better than a profiled sheet or a metal tile?

Often experts call given material profiled sheets. In fact, this is the same lightweight slate, but not asbestos cement is used for its production, but thin steel sheets. Accordingly, the weight of the material is much lighter than that of slate.

Modern manufacturers produce two types of corrugated board:

Decking without coating.
Corrugated board coated with polymer materials owing to what the product has various color scale.

The main advantages of corrugated board:

Little weight.
The material is fireproof.
Beautiful decorative indicators.
Low cost.
Service life - 45 years.

The main disadvantages of corrugated board:

The angle of the roof slope should be no more than 8 degrees.
Increased noise during precipitation.
The risk of lightning getting into a corrugated roof increases significantly. Therefore, the arrangement of a lightning rod is required.

For those who still have not decided which material is better: profiled sheet or metal tile, we advise you to choose based not on operational qualities materials, but from the budget you are willing to spend on roofing and aesthetic considerations.

Recall that covering the roof with metal tiles is not a cheap pleasure. But the resulting effect cannot be compared in its beauty with any other material.

At the same time, comparing the category: metal tile or corrugated board, you need to know that corrugated roofing will not look so chic, but will last for a long time faithfully, without delivering unpleasant moments to their owners.

It is important to know: when the slope of the roof slope is less than 15 degrees, it is not advisable to use metal tiles. It is better to use corrugated board or slate.

If you still haven't decided that better metal tile or a professional sheet, consider characteristics metal tiles.

Characteristics of metal tiles

So, what is better metal tile or slate? Or maybe corrugated board. Consider the main characteristics of the metal tile, its advantages and disadvantages.

So, a metal tile is a roofing covering, which, by its appearance imitates natural tiles.

The metal tile is produced by stamping: sheets of galvanized steel (thickness 0.4-0.5 mm) are certain form, after which it is applied to them polymer coating polyester, polyvinyl difluoride or plastisol.

Due to the fact that it is not recommended to cut metal tiles, modern manufacturers produce material with standard sizes:

Width - 1.18 m.
Length: 3.63 m, 2.23, 1.18 and 0.48 m.
Profile height - 23, 18, 15 mm.

Depending on the size, the weight of the metal tile also fluctuates: from 1.9 to 17.7 kg.

Based on the project and design features roofs, you need to calculate required amount metal tiles, given its size.

The main advantages of metal tiles:

The material is quite flexible, so it is suitable for roofs of any shape and configuration.
In order not to resort to pruning, you can purchase material of the required size.
Environmental friendliness.
Excellent external characteristics.
The durability of the coating is up to 40 years.
Different pricing policy (there is material, both economy and elite class).

The main disadvantages of metal tiles:

Due to incorrect calculations, material waste can be quite high - up to 40%.
Installation requires certain knowledge and skills, since it is strictly forbidden to walk on the coating.
Creates increased noise during precipitation.
We do not have thermal insulation properties.
Condensation may form with a sharp change in temperature and humidity in the environment.

In Europe, manufacturers and consumers have come to the following conclusion: the best metal tile is Monterrey. What are the features of this profile? Its wavelength is 35 cm, which looks especially impressive on roofing.

Modern Russian market roofing materials breaks records for the sale of metal tiles different manufacturers. The following brands are especially popular with Russians: Ruukki (Finland); Grand line, Metallprofil, Interprofil (Russia), MERA SYSTEM (Sweden) and others.

Unambiguously answer the question: which is better metal tile Russian or foreign manufacturer it is forbidden. It all depends on the design features of the roof and your budget. It is quite clear that domestic counterparts are cheaper.

Variety of metal roofing

Modern manufacturers use several basic coatings to cover metal tiles:

Polyester - base this coverage made of polyester paint, which has a glossy surface. This is the thinnest and most inexpensive coating (thickness 25 microns), but, nevertheless, it is suitable for different climatic conditions. Color fastness is good.
Matte polyester has a coating thickness of 35 microns and a matte finish. Retains mechanical and color stability in any climate.
Pural is an innovative coating, unfamiliar to a wide range of consumers. Its thickness is 50 microns, the base is polyurethane. This coating is heat-resistant and adequately withstands temperature changes, much better than polyester.
4. Plastisol - the thickest coating - 200 microns. The base is polyvinyl chloride (PVC) with an embossed surface, which perfectly withstands atmospheric influences and mechanical damage. A word of advice: in hot regions, give preference to coverage light shades, they will heat up less and, accordingly, fade less in the sun.
The LDPE coating of polyvinyl difluoride and acrylic (80%x20%) has a thickness of 27 microns and a gloss. Its colors mimic "metallic". The coating does not fade, resistant to mechanical damage and aggressive environments. The service life of this coating is the record holder among all coatings.

Design features of metal tiles

Knowing the features and characteristics of each coating, you can easily decide which metal tile is the best for the climatic features of your region.

Varieties of the metal tile profile

Each model of metal tile has its own characteristics:

drawing;
and profile depth.

The most spectacular is the relief profile, which has big step. After all, it is not for nothing that Europeans prefer Monterrey metal tiles (we talked about this above).

What is a metal tile? Manufacturers tacitly divided the metal tile into the following subspecies:

The wave height is the smallest (up to 50 mm).
The wave height is large (50-70 mm).
symmetrical wave.
Beveled asymmetric wave.
Exclusive pattern (elite-class material).

What is the best metal tile, with a particular profile - you decide.

It is important to know: the wave height, pattern, pitch and depth of the profile do not in any way affect the quality of the material. These characteristics determine its external decorative performance.

How to choose a quality roofing material?

Which manufacturer to prefer is also up to you. Although there is a certain pattern: the quality of the material is higher, the more famous its brand and manufacturer. Accordingly, its value is also determined by these same indicators. As a rule, metal tiles are proven famous brands is about 15% higher. Decide for yourself what is more important to you: the durability of the roof or its cost?

Tip: in order to purchase high-quality metal tiles, protect yourself: ask the seller for a quality certificate (it must come from the original manufacturer), the conclusion of a sanitation station and a fire safety certificate.

Most manufacturers with a name mark their product, indicating information about who and where the sheet of material was produced.

An equally important predetermining factor in the choice of metal tiles is the geometry and size of the wave. Unfortunately, many negligent sellers try to slip inexperienced consumers with tiles, the shape of which was given on unadjusted and worn-out machines. What is the risk of such a purchase? Such sheets of metal tiles cannot fit perfectly one to the other, forming gaps. Subsequently, this will affect only the beauty, but also the quality of the tightness of the roofing.

We hope our article will help you to make your right choice those who have not yet decided which is better: metal or slate.

Recall that in order to properly mount the roof of a metal tile, you need to purchase special additional elements:

Cap and bar for the ridge;
Overlay for the valley;
Planks for internal and external corners;
Plank for seams and joints.

Choosing roofing for the home, often the developer thinks that slate or corrugated board is better? Despite the fact that both types of material belong to the economy class, there are differences in their characteristics, strength and practicality indicators. To determine your preferences, you should compare both materials.

It is called professional flooring steel profile with trapezoidal corrugations, made by cold bending. Galvanized or galvanized painted steel is used, which ensures high strength and long service life.

Slate is a material made from various components, which includes cement, asbestos, water, chrysolite chips and much more. Today there are several varieties of material, but let's talk about asbestos slate, as the most famous and used for roofing.

And for best comparison, factors such as:

weight of one sheet of products;
lifetime;
noise reduction level;
simplicity, ease of installation;
aesthetics;
price.

Weight

The weight indicator is important for ease of installation with my own hands and reducing the total weight of the roof, and hence all structural units. The less the roof weighs, the lower the load on Wall panels, foundation. And here the professional list definitely wins. A slate sheet in 8 waves reaches a weight of 26 kg, which is 14 kg per 1 cm2, a lot. The weight of the profiled sheet also depends on the thickness, but it is rarely heavier than 15-18 kg. In terms of each square meter the difference will be up to 5 kg, which is significantly lower.

Lifetime

Both materials are guaranteed for 10-12 years, but a roof made of slate and corrugated board can last much longer. It should be remembered that the slate sheet is a fragile material that cannot withstand point-type loads. Therefore, a split from a good hail or tool during installation is guaranteed. Over time, moss grows on the sheets, especially when the roof is set up in the shade of trees, which not only spoils the appearance, but also reduces performance.

Modern profiled sheet has a protective coating polymer compositions, therefore, does not lose its qualities during operation and is easy to wash. In general, profiled sheets are easy to care for, cleaning once a year is enough to “renew” the roof. But at the same time, you should monitor the flooring, any deformation such as a chip or scratch will cause the material to rust, which slate does not and will not have.

Noise isolation

Slate wins here, profiled sheet is metal, so the sounds of rain, wind, falling branches will be heard perfectly. In order to reduce the noise level, it is necessary to strictly observe the installation technology, equip a sound insulation layer, which means that the cost of the roof will increase.

Installation

Comparing slate with a corrugated sheet, we note the increased dimensions of the latter. This means that it is easier to work with a profiled sheet - there are fewer joints. At the same time, slate elements are heavier than metal ones, they are more difficult to lift, helpers are needed. Another point is the absence of consumption when laying the profiled sheet, and this is already a decrease in the total cost of the structure.

Aesthetics

Both materials have different shades and therefore look attractive. In addition, additives increase the strength characteristics of slate. The difference is that the profiled sheet has a gloss, the wave slate does not, but it heats up less.

roof price

Slate is cheaper, but not always. Given the large area of \u200b\u200bcorrugated board, calculations should be made more carefully. Let's add ease of installation, ease of searching for fasteners, reduction in the cost of arranging a solid crate, foundation and no costs - the price of a profiled sheet will already seem quite inexpensive.

Important! To make a final choice, it should be remembered that the profiled sheet does not contain asbestos, which is harmful to health.

Advantages and disadvantages

Choosing a roof from corrugated board, the developer receives:

reduced weight load
optimal degree of rigidity;
resistance to atmospheric phenomena;
neutral reaction to aggressive influences.

Of the minuses: a little soundproofing and a wide range of prices.

If slate is placed on the roof, then the coating is distinguished by:

long service life;
low noise threshold;
increased static strength;
no corrosion.

Of the minuses: fragility, heavy weight, reduced performance during long-term use.

Scopes of slate and profiled sheet

If we are talking about very economical construction or temporary, household facilities, where the strength indicators of the crate and foundation are not so important, we definitely choose slate. In all other cases, preference should be given to corrugated board.

Sometimes it comes to replacing the old roofing sheet with a new one. If the house permanent residence, there are children in the family, then corrugated board will be not only a good alternative, but also an excellent inexpensive and quality option. And when they are infrequently in the house, the decision on whether to lay a profiled sheet or slate is made by the developer. Asbestos will not cause much harm, and if there is a strong crate and slight deformations of the coating, it is enough to replace a couple of sheets of slate, but not spend money on a complete alteration of the roof.

So, the choice of which slate or corrugated sheets is better is yours, each coating has its own advantages and disadvantages that should be considered during construction.

Alexey Yakovlevich, Moscow asks a question:

Hello! The construction of the house started by me is coming to an end. It remains to build a truss system and cover it with a roof. I haven't decided yet what material to choose. While considering 2 options - slate and metal. In my opinion, slate is a roofing material that has been proven over the years. The houses under it have been standing for decades. Plus, it's cheaper than the others. Friends convince me to abandon it and make a roof of metal tiles. They assure that the roof from it will be more durable, and this is much more important than low cost. Please tell us which is better: slate or metal tile? What is best for roofing? Thanks for the consultation.

The expert answers:

The choice of roofing material must be made on the basis of a clear comparison of all the pros and cons of materials.

Slate until recently was one of the most common roofing materials. for a long time regularly performed its functions, and its characteristics exceeded those of soft roofs that needed frequent repairs. It is worth saying that there were few options for overlapping buildings before. In addition to slate and roofing felt, burnt tiles and sheet steel were used, but their installation was difficult.

Today, the variety of roofing materials does not surprise anyone. Among the best of them is metal tile. It is a kind of synthesis that combines the external attractiveness that a tile has and the reliability of a metal roof. True, there are other metal roofs. For example, corrugated board also serves as a reliable shelter from rain and snow, but the metal tile looks much more elegant.

Asbestos cement slate cannot boast of a presentable appearance. But limited funds developers choose it. It should be noted that the design features slate roof improves paint. In addition, the colorful layer makes it a little stronger, but the slate will often have to be repainted. A slate sheet covers about 2 m², but it also weighs decently. The slate coating can withstand an impressive mass, but at the same time it is quite fragile. It can be damaged by laying it on an insufficiently even crate or awkwardly hitting it with a hammer. It cannot do without a hammer, since the sheets are attached to the crate with slate nails, moisture will certainly get into the holes under which.

On the other hand, asbestos cement is a good sound absorber, and in the house the sound of drops on the roof is almost inaudible. Slate roofing does not snow as fast as a smooth metal roof, but slate requires a stronger base structure than lighter materials. Based on the totality of indicators, slate could be considered a good roof, but it is very afraid of large hail, which ceases to be a rare natural phenomenon.

Metal tiles, unlike asbestos-cement building materials, can withstand the elements. Of course, it will be crumpled, but the house will be protected. It can be attributed to its "noisiness", since when it rains on metal roofing will beat "peppy drum roll". A metal roof is also prone to condensation on the inner surface. Damage protective coating metal tiles will accelerate its corrosion, therefore, strict requirements are imposed on the cutting and installation of the roof.

At the same time, the high sound transmission factor is negated by the thermal insulation under the metal roof, which will absorb noise. In addition, metal tile is much lighter than slate. truss system under it it can be lighter, although this will not affect the consumption of wood, since a lot of it will be required for the installation of battens and counter battens.

The metal tile compares favorably with slate in that it can cover roofs of complex configurations. slate sheets without problems, they are placed only on 2-pitched bases or, in extreme cases, on 4-pitched ones. It can be added that today much attention is paid to the environmental component of materials. According to many, slate, in which there seems to be no free asbestos, remains a strong carcinogen.

Perhaps, as a result, you will decide that there are other materials better than slate or metal tiles, but there are simply no ideal building materials in nature.
