Roofing

Roofing material for the roof should be selected with special care, given not only its decorative properties, but also operational characteristics. We will tell about the types, features and intricacies of the coating selection in this article.

How to choose roofing material

Before purchasing a material for finishing the roof, it is necessary to determine exactly what the factors should be taken into account for this:

1. The load on the roof, which implies the weight of the roofing pie, the intended mass of the snow cover, the middle wind loads at a particular region.
2. Architectural design features. For roofing on the roof and to select a suitable material, it is important to take into account the design features of the structure, configuration and bias of the roof.
3. Climatic and operating conditions on which the roof service depends.
4. The durability of the material and its fire resistance. For example, it makes no sense for the household building on the site, it makes no sense to acquire expensive, whereas for a residential building it is better to choose a roof that will serve not one dozen years.

All roof coverings have a certain warranty period. It is worth noting that in some cases, if the material was laid in compliance with all rules, the real service time can significantly exceed those that are declared by the manufacturer. We will deal with this Read more:

1. A mild tile guarantee is often from 15 to 20 years and applies to such concepts as tightness, integrity, lack of production defects. Warranty obligations do not apply to the preservation of its source material. The actual life of the soft tiles is at times exceeds the warranty, and such a roof can serve without repair from 30 to 50 years.
2. Metal tile manufacturers give a warranty from 5 to 15 years. As in the case described above, the coating over the course of this time can change the shade, burn, contaminate, change the glossiness. The real service life of the metal tile often fluctuates from 30 to 50 years.
3. The warranty period of the genuine tile is 20-30 years, which applies to the frost-resistance of the material. Practice shows that natural tiled coating is very durable and can even serve even 100 and 150 years.
4. Slate has a smaller service duration, in reality it ranges within 30-40 years, while warranty obligations are supported by the manufacturer for 10 years.
5. Bituminous wavy sheets with proper laying and operation do not require repairs about 15-25 years. The warranty on them is 15 years and does not apply to the preservation of the material of its original shade.
6. Roofing steel and profiled flooring have a warranty period equal to 15-20 years. Warranty obligations do not include risks associated with improper transportation or operation of goods. In real life, professional flooring and steel can serve up to 50 years.
7. Shale covers are also durable as natural tile. The warranty on them varies in the range of 30-40 years, whereas in fact such a roof can maintain its integrity within 150 or even 200 years.
8. Folding roofs serve about 50 years, their manufacturers give the buyer for 15-20 years warranty.

When choosing a material for finishing the roof, it is important to pay attention to such characteristics:

1. Composition and environmental coating. It is important that the roof, especially on the residential building, was safe for a person and did not allocate harmful substances into the environment.
2. Texture, density, material color.
3. Maximum and minimum roof slope suitable for a specific type of coating.
4. The main methods and principles of installation of roofing material.
5. Features of roofing roof carpet, that is, the presence and characteristics of the layers included in the roofing pie.
6. The scope of application of certain coatings for roofs, pros and cons of each of the materials.
7. Prices for roofing materials for roofs.

Each of the coatings has its scope and applies in certain cases:

1. Rolled roofing materials are ideal for flat roofs. Work on their installation can be performed quite quickly.
2. Sheet coverage is convenient to use where it is necessary to process large areas.
3. Small roofs like tiles are durable, look stylish, expensive and prestigious. Most often, they are used where it is necessary to achieve a beautiful effect and emphasize the status of the owner of the house.
4. The bulk materials are needed where it is important to create a seamless, durable, waterproof coating, while spending a minimum of time. Bulk roofs look not as attractive as, for example, tiled, but they cost much cheaper and serve for a very long time.

Species and features of roofing materials

Ceramic tile

Ceramic tile is produced by molding and burning the clay mass, the natural color of such a coating is usually red-brown. Separate tiles have dimensions of 30x30 cm and weigh 2 kg each. If you decide to separate the roof of the tiles, make sure that the slope of the structure ranged from 22 ° to 60 °. If the slope of your roof is sharper, additional mounts are necessary for the coating. With a stronger roof it is important to create improved ventilation and waterproofing.

The advantages of ceramic equipment should include such characteristics:

• ease of care and cleaning;
• good soundproof properties;
• absolute nonopication, resistance to moisture, good frost resistance. Such a roof withstands more than 1000 cycles of freezing and thawing;
• rich color palette, as well as a variety of forms;
• porosity, which provides good vapor permeability.

From the flaws of the coating, you can call as:

• a large mass, due to which you have to create an exceptionally strong solinge system;
• fragility of parts;
• the complexity of the use on the roofs of a complex configuration.

Cement-sand tile

By type, cement-sand tile is very reminiscent of ceramic, but due to a simpler manufacturing process it costs somewhat cheaper. The bias of the roof for the use of cement-sand tiles should be 20 ° -60 °.

Consider the advantages of such a coating:

• over time, the material not only does not become fragile, but, on the contrary, acquires greater hardness and density;
• such a tile perfectly transfers the effect of any aggressive chemicals, as well as radiation;
• frost resistance of the coating is one more advantage. Like the previous type of roof, cement-sand tile makes up to 1000 frost cycles.

The material has some minuses:

• large weight and massiveness that weight damage the roofing pie;
• risk of damage in the process of transporting coverage to the site of construction work.

Bituminous tile

Such a tile is made from bitumen tiles covered with several layers: fiberglass, cellulose, polyester, paint. Separate elements of such material are perfectly joined with each other, creating although not seamless, but completely waterproof coating. Due to the elasticity, such a tile is nice well, which is very useful in case your roof has a complex form and configuration. The bias of the roof to use such a material ranges from 12 ° to the maximum indicator.

Positive properties of bituminous tiles:

• due to high plasticity and flexibility it is very difficult to break;
• the scope of the use of material is very wide, it can be mounted on the roofs of any shape, complexity, slope, configuration;
• beautiful sound insulation qualities - another plus of bituminous tiles;
• such a coating does not floss, does not rot, it does not mold, not subject to corrosion.

Among negative qualities it is worth highlighting as:

• combustion;
• under the action of ultraviolet rays, the tile loses its color;
• it is impossible to engage in the installation of material in winter.

Metal tile.

Metal tile is galvanized steel coated with a layer of polymer material. In its texture, it resembles a small-piece roof consisting of separate small elements. In fact, such a tile is a solid leaf of a fairly large area. Metal tile can be mounted on the roofs of almost any slope, the minimum indicator is 15 °. Nevertheless, if the slope of your design is less than 20 °, it is better to provide additional sealing of the joints.

Of the advantages of metal tile, it is worth highlighting the following:

• simplicity and speed of laying;
• stability before the action of mechanical loads;
• small cost;
• low weight;
• no risk of damage during the transportation of goods.

By minus we count:

• bad sound insulation properties;
• the presence of a large amount of cast material that remains after installation of the coating.

Asbesto-cement slate

Asbestos-cement slate is made from a mixture of Asbesta and Portland cement. The ratio of components is 15% to 85%. During the production process, a wavy leaf is 120x70 cm. On the roof, such sheets are mounted using nails, under which put small rubber parts. They are needed to protect the fragile slate from cracking after a hammer over it. Such a coating is customary to be installed on a predetermined waterproofing layer, which is made of rubberoid or other suitable material. Asbestos-cement slate cannot be called externally attractive material, which is most often used in economic buildings.

The pluses of the material should include:

• low cost;
• simplicity of work.

Cons of asbestos-cement slate Such:

• high fragility;
• the presence in the composition of substances harmful to humans;
• low aesthetic qualities;
• raming, leaning towards the formation of mold, moss, fungus.

Professor

Professional flooring is the roof of roofing iron. Professional steel made of hot-dip galvanized steel having increased strength and rigidity. Such a coating can be mounted on a roof with any slope, starting from 10 °. Since the material looks not too attractive, it, like slate, is used to decorate household buildings, sheds, etc.

The positive properties of the professional flooring are:

• it is easy to work, mounted in the shortest possible time;
• professional flooring flexible and durable;
• serves many years;
• it is relatively inexpensive.

The material has a number of minuses:

• low aesthetic qualities;
• bad noise insulation.

Steel folding roof

Such a coating is smooth steel sheets that are connected to each other with special hooks. Seams that are formed between separate details are called false. Folding roofs can most often meet at churches, industrial facilities, antique manors.

Folding roof is good because:

• absolutely not lit and not floss;
• well bend, thanks to which it can be used on complex structures;
• may be laid in winter.

This material has cons:

• it is poorly withstanding shock loads, with a strong impact on the coating can be dent;
• steel folding roof needed additional insulation.

Copper and Aluminum Folding Roof

The roof decorated with copper or aluminum roofing material looks very attractive and has a long service life. It costs more than many analogues, but such costs are fully justified.

The positive properties of the copper and aluminum folding roof can be attributed to:

• nonseasing;
• resistance to precipitation, chemicals, corrosion;
• ecology, hygienicity.

Of the minuses of such a coating, only its significant cost can be distinguished.

Bituminous slate

Such a material is made of cellulose fibers that are impregnated with bitumen, resins, various pigments and additives, attaching additional strength, flexibility, elasticity, external attractiveness. Bituminous slate is suitable for roofs with a slope of 5 ° and more.

Pluses of a bitumen slate:

• low weight;
• good elasticity and flexibility;
• ability to use on the roofs of a complex form.

Cons:

• unstability of the shade, over time, the coating fades in the sun;
• combustion;
• bad frost resistance.
