The better to cover the roof with slate or metal tiles. Which metal tile is better: advice from experienced craftsmen. Disadvantages of metal tiles compared to ondulin

Modern market building materials is able to offer the consumer a fairly rich assortment of both goods and services. To a greater or lesser extent, any roofing material is able to satisfy the basic needs of the consumer. To solve the problem with the choice, the buyer will be offered more than one attractive option. At the same time, even the bestsellers made according to special orders, have not only a number of advantages, but also their disadvantages. Each of them has its own weak and strong features.
But after all, every buyer wants to have the most profitable purchase, make the most optimal choice coverings for the roof of your premises.

The article will help to find out the advantages and disadvantages of the two most commonly used roofing materials: slate and metal tiles. For the consumer to solve the dilemma of what is better to choose: a traditional slate roof, or an innovative version of metal tiles, such information is valuable.

General information about slate

This is the most common roofing material of the last century. It is made from asbestos cement.
Slate performed its functions more regularly than other coatings of that time:

  • roofing material,
  • burnt tiles,
  • sheet steel.

And although the rating of slate today is significantly reduced by metal tiles, soft bituminous coatings and others. Many still prefer this coating, given its low cost and durability of operation when organizing simple maintenance.

Advantages of a slate roof

  1. Working with slate is easy. A slate sheet that has become unusable is easy to replace with a new one.
  2. Asbestos cement does not corrode, does not rot.
  3. Having provided the necessary humidity, this building material can be stored for a long time without any damage to its quality.
  4. The heat resistance of slate attracts many building owners in areas with high density their buildings, ensuring fire safety.
  5. The roof of slate heats up slightly from the sun, in the heat the house is cool.
  6. Asbestos cement - absorbs sounds well, during rain in the house under slate roof Almost no "drum roll" is heard.
  7. Painting increases the design qualities of slate, its strength and waterproofing.
  8. It is able to withstand an impressive weight, so roofers can move freely along the roof without fear of damage to building materials.
  9. The surface of the slate sheet is porous, which helps to prevent spontaneous cleaning of the roof from snow; if snow deposits slide off the roof, then not as fast as from smooth decking.
  10. Given these advantages, slate has a relatively low price.

Slate Disadvantages:

  1. The material is unpresentable appearance, which can be fixed by painting, but this will have to be done regularly and often enough.
  2. The fragility of asbestos cement makes slate vulnerable.
  3. Installation of such a roof is carried out with the help of nails. It is rather embarrassing to hit the sheet with a hammer, or lay it on an uneven crate, to damage the material.
  4. The slate sheet has an impressive weight (more than 20 kg).
  5. Precipitation gets into the nail holes, causing rotting of the timber frame of the crate.
  6. Sheets of slate can be overgrown with moss.
  7. Large hail - a frequent natural phenomenon - can permanently damage the slate on the roofs of buildings.
  8. Asbestos cement, from which slate is made, is recognized as a carcinogen.

Ways to neutralize some of the negative properties of slate

  1. Painting slate sheets enhances waterproofing and improves the aesthetics of the appearance.
  2. Install a strong crate for attaching the slate.
  3. Roofs overgrown with moss can and should be cleaned.
  4. Do not be careless with construction waste.

In case of improper disposal, for example, by pouring them out onto the road, it is likely that slate fragments will be crushed under the wheels of cars to a powdery state, and this will become a clear threat of carcinogenic asbestos with dust entering the respiratory organs of people. To neutralize the negative effect of asbestos dust, which contributes to the development of lung cancer, construction debris containing slate or its fragments should be securely buried.

All about metal tiles

Metal tile is a modern roofing material – an attractive, original, reliable and elegant synthesis of tiles and polymer-coated steel. This confident leader sales today(about 70%), left far behind all competitors, thanks to its unique qualities. It is made from profiled thin steel, covering thin layer polymer.

What is famous for metal tile

1. It originally combines reliability metal coating and visual appeal of the tiles.
2. An innovative product has an advantage over other competitors due to the following features:

  • aesthetic appearance,
  • durability,
  • easy installation,
  • no need for meticulous care.

3. The starting push of popularity is the light weight of this product.
4. A less powerful rafter system is needed, as for a slate roof, which automatically reduces the load on the walls and foundation of the building.
5. Moss does not settle on such roofs.
6. This type of roofing allows the perfect installation of roofs of complex configurations.
7. Properly installed metal roof covering is not afraid of leaks.
8. Metal tile, due to its superior qualities and properties, can withstand the blows of the elements, hurricane, hail, the house will be protected by it.
9. It has protection against fading in the sun, polymer coating long time retains its original color.

Characteristic disadvantages:

  1. Factor high level sound permeability turns even light rain under this coating into a roar of "cannonade".
  2. A metal roof tends to form condensate under it from the inside, which ambiguously causes premature corrosion.
  3. Strict requirements are imposed on the cutting and installation of metal tiles, which prohibit damage to the polymer coating of this material.
  4. Lighter device truss system, but with more frequent sheathing required for this type of roof, it also requires a large consumption of wooden building materials.
  5. When installing a roof made of metal tiles with a metal component, the installation of lightning rods is a must.

How to smooth out the imperfections of a metal tile

For someone, it may be a discovery that a metal tile is just decorative coating. insulating layer solves problems not only with insulation attic space, but also saves the building from sound persecution of the elements, absorbs sounds, protects from excessive noise of rain, wind, snow. The outer part of the roof - the metal tile - is designed to perform the main function of protecting the inner layer. To avoid damage to the top layer of a fashionable roof, it is necessary
1. perform certain rules during the installation work skillfully use tools and devices:
a) the protective layer burns out at the cut site when working with a grinder saw, and sparks are likely to damage the entire surface of the sheet, so you can only cut metal tiles with cut scissors, or use a special nozzle on a drill;
b) when attaching the roof deck to the battens, it is imperative to use, without substitution, the essential components:
self-tapping screws with a protective color, specially designed for such fastening,
EPDM gaskets for corrosion prevention.
2. Installation should be entrusted to conscientious and qualified specialists.
3. Ignoring the prohibitions and requirements of instructions from manufacturers is fraught with negative consequences:

  • shortening the life of the roof
  • extra financial expenses.

The result of a conscious choice

Not found in nature and not yet created perfect material for the roof. After weighing all the advantages and disadvantages of the proposed roofing options, everyone is able to compare their capabilities, understanding what will happen in the future and what should be avoided. And make your choice as the only rational decision.

How to close the roof: slate or metal tiles? Both of them - sheet material. Similar questions are often found on the forums. Someone advises based on their own experience, others - from what they have ever heard. But before making a decision, you need to thoroughly study the features of both materials and compare them in 6 important parameters.

1.Appearance. In this category, it would seem, metal tiles should definitely win. red or green roof looks much more profitable than dull gray slate sheets. However, this is an outdated stereotype. Slate can also be purchased in color (it is produced different color and shade) or paint, which will add durability to the roof, because. paint is an additional protective layer.

2. Price.A detailed calculator is available on the website. You can calculate the exact cost according to the parameters of your roof required amount slate and metal tiles. Usually the difference is about 20% in favor of slate. To date, this is indeed the most accessible view roofing material.

3. Soundproofing.Rain and hail are the main enemies of metal tiles. It is unlikely that you will be able to sleep peacefully. But slate does an excellent job with this role. Therefore, if there are more rainy days in a year than sunny days, make a decision in favor of the most sound-absorbing materials.

4. Sheet size and weight.This is important question when installing a roof. Two sq. meters of metal tiles weigh 10 kg; 1,645 square meters of six-wave slate weighs 21.4 kg, but there are also lightweight versions of slate with a reduced sheet thickness.In addition, lighter sheets of metal tiles do not always withstand increased wind load.

5. Environmental friendliness.On this issue, there are not as many conflicting opinions around the metal tile as around slate. There is a judgment that slate is unsafe. In fact, slate is made from natural mineral chrysotile, cement and water. Slate is a safe roofing material. Other types of asbestos are harmful - amphibole, but slate has never been made from them in Russia. Therefore, in terms of environmental friendliness, both materials win.

6. Wear resistance.Slate, as an invented material, is already over 100 years old, and during this time it has managed to establish itself as a durable and reliable material. The minimum service life is 20-30 years. If we talk about metal tiles, then manufacturers call terms of 15 years. It all depends on whether it was laid correctly, and how quickly corrosion appears on it, which, last but not least, depends on weather conditions which are not always favorable in our country.

When choosing a roofing material, you should rely on the tasks you want to solve, whether it is cost savings, or sound and noise insulation, or durability.

Today there is a large number of roofing materials and choosing the most suitable one from it can be quite difficult.

Difficulties arise due to the fact that roofing materials differ from each other in terms of service life, cost, complexity of installation work and other properties.

Let's try to determine which is better: ondulin, metal tiles, corrugated board or slate. To do this, consider the main pros and cons of each of these roofing materials.

This material is manufactured by the French company of the same name. made from natural cellulose fiber, which is made from waste paper.

It is issued in the form corrugated sheets, which have the following parameters:

  • Length - 200 centimeters;
  • Width - 95 centimeters;
  • Thickness - 3 mm;
  • Weight - 6.5 kilograms.

Ondulin sheets have the following advantages:

  1. Long service life (under the guarantee it is 15 years, but in fact it can be up to fifty years);
  2. Ecologically pure material(only natural ingredients are used in its production);
  3. Strength (easily withstands a layer of snow);
  4. Many colors and shades;
  5. Low cost of the material;
  6. Ease of installation (largely due to the low weight of the sheets).

But at the same time, ondulin also has disadvantages. These include:

  1. Over time, the ondulin coating loses its brightness;
  2. It ignites at a temperature of two hundred thirty - three hundred degrees Celsius;
  3. Surface roughness, as a result of which a layer of snow does not roll off the roof;
  4. At very low temperatures, the material becomes brittle;
  5. At high temperature ondulin begins to melt.

metal tile

Produced from sheet steel with a thickness of 0.4 - 0.5 mm. A layer is applied to the sheet polymer materials, which give it color and enhance anti-corrosion protection.

The main advantages of metal tiles:

  1. Affordable price;
  2. Long service life (50-80 years depending on);
  3. Ease of installation work;
  4. light weight (one square meter weighs four to five kilograms);
  5. It has many colors and shades;
  6. Can be used for different types roofs, provided that the angle of the roof slope is not less than 12 degrees;
  7. The material is sold together with the accessories necessary for laying;
  8. Not affected sun rays, precipitation, fungi, mold. It is also well protected from chemical and mechanical attack.

The disadvantages of metal tiles are:

  1. High thermal conductivity, tk. the metal tile is made of steel;
  2. Low ;
  3. High consumption for roofs with complex structure, because there are too many scraps of material left;
  4. Condensation accumulates on the inside of the roof. To prevent this, it is necessary to make a gap between the metal tile and the waterproofing film;
  5. In a place where the metal tile has been scratched, corrosion may occur.

Decking

This material is, in the manufacture of which galvanized steel is used. The cold profiling method gives the profiled sheet a wave-like shape.

Also, this method increases the rigidity of the material. In the manufacture this material for roofing, the steel sheet is covered with several layers. The first coating protects the sheet from corrosion. The second layer is applied with a primer. Then outside coated with varnish, and the inside with a polymer.

Advantages of corrugated board:

  1. A small number of joints during installation;
  2. Long service life (up to fifty years);
  3. The polymer layer makes the material resistant to mechanical damage;
  4. Profitability;
  5. Environmental friendliness;
  6. Resistant to corrosion;
  7. Many forms of material;
  8. A large number of colors and shades;
  9. Versatility.

Disadvantages of corrugated board:

  1. Low sound insulation;
  2. Accumulation of condensate on the inside of the roof;
  3. Difficulty in laying in hard-to-reach places (slope corners and roundings).

Asbestos-cement slate

For manufacturing, a mixture is used, which includes cement, water and fibrous asbestos. To obtain a durable roofing material, this mixture is molded and then waited until it hardens.

An important role is played by asbestos-cement fibers. They form a reinforcing mesh that increases mechanical strength slate. It is important to note that the dimensions of the slate sheet can be different.

The thickness of the sheet is in the range from 5 to 9 millimeters, and the width directly depends on the number of waves. There may be six or eight. The difference between the sizes of a six-wave sheet and an eight-wave sheet is negligible, but on an eight-wave sheet the waves are more compact.

The advantages of asbestos-cement slate include:

  1. Low price;
  2. Practically does not heat up under the influence of the sun's rays;
  3. Does not corrode;
  4. The material is not combustible;
  5. Has good sound insulation;
  6. Ease of repair work.
  7. Sometimes used to make a fence or fences for garden beds;
  8. Long service life;

The disadvantages of slate are:

  1. The composition of the mixture from which slate is made includes asbestos. It negatively affects respiratory system person;
  2. After a few years, the roof may become covered with moss;
  3. The material is quite fragile, so care must be taken during transportation and installation;
  4. Material weight. It will be quite difficult to perform installation without an assistant;
  5. Limited colors and shades. But if you wish, you can paint the slate yourself without removing it from the roof.

In this article, we tried to find out which is better: ondulin, metal tiles, corrugated board or slate. Each of these materials has its pros and cons and it is difficult to single out the best one.

Therefore, when choosing a material, it is necessary to take into account the complexity of the roof structure, its angle of inclination, the climate of the area, as well as the funds allocated for the purchase of roofing material and installation work.

When you need to make a roof, the question always arises: what is the best roofing material? Known materials for these works are slate, metal tiles and ondulin.

Criterias of choice- durability, ease of use, price and, of course, beauty.

Which is better - slate or metal tile?

Compare slate and metal tiles . Metal roofing is always more expensive but it's already finished material not requiring painting. From an aesthetic point of view, many also like metal tiles more.

But with the help of slate, you can also achieve a similar effect. cutting the slate into smaller pieces by applying frequent on the whip and using paint and the look will be no worse.

Wherein the process of installing a roof becomes more time-consuming, there is a need to purchase paint. And if you calculate the costs, then the difference in price may not be that big.

Speaking of durability, then slate is more durable than metal tiles, since it is susceptible to corrosion.

Asbestos and cement, from which slate is made, more resistant to natural conditions , but the surface of the slate can be overgrown with moss, for this it needs to be processed or painted.

Metal roofing is lighter when the slate is heavy and there is a very large load on bearing structures. At strong wind because of the lightness, the metal tile can be easily torn off, and if the wind is not strong, it still moves and creaks.

At the same time, slate lies very firmly on the roof and the wind is not afraid of it. For both roofing materials You still need good wind deflectors.

When it rains, the metal tile rattles loudly. The slate is quieter. The metal tile also heats up very strongly in the sun. On the inside metal tiles, condensation is formed.

The slate doesn't get that hot. No condensation will form on it., since the slate can absorb some of the moisture.

Ondulin or slate - which is better?

Ondulin and slate have good heat and sound insulation and there is no condensation on them. Ondulin is lighter than slate, it requires less bulky supporting structures, and it is easier to mount it.

In the sun, ondulin heats up more than slate and under its influence softens, so the roof becomes unreliable and it is impossible to walk on it in the summer.

Ondulin coating can be damaged by hail or others natural disasters, since it is less durable than slate. Ondulin is a combustible material, it carries a certain danger.

As for appearance. Ondulin has a variety of colors and is more attractive in appearance than unpainted slate. But there is one drawback here, ondulin fades quickly and unevenly in the sun and the coating loses its original appearance.

Profiled sheet is lighter than slate, hence less load on the building structure and more convenient installation. In terms of service life, both materials are durable.

The slate is more fragile and may break under mechanical stress.

Profiled sheet roof is noisier additional soundproofing is required. Here is the slate ahead. Slate also has better thermal insulation.

Decking is produced according to modern technologies, it is coated with a polymer coating has a variety of colors. But at mechanical action for polymer coating it can be broken and the process of corrosion will begin.

Each roofing material has its pros and cons. To choose a material for blood, you need to determine your priorities. What is more important?

Appearance, weight, ease of installation, reliability, durability or price. What do you need to build a residential building or utility room? Only then make a choice. Until now, this choice is painful for many. Good site.

And also watch a video on how to choose the right roofing material:

Choosing roofing for the home, often the developer thinks that better slate or decking? 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.

Profiled sheeting is a 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.

The 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 bear the load. point type. 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.

The modern profiled sheet has protective covering 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.

Mounting

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, wave slate no, but it does get hotter.

roof price

Slate is cheaper, but not always. Considering large area corrugated board, you should carefully make calculations. 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 characteristics 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 high-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.
