Roofing materials: types and properties. Weldable roofing materials

The roof protects the house from precipitation, frost and other negative environmental factors. Today it is customary to use different types of materials for its coverage. It can be hard, soft, profile, flat, roll and piece solutions. Some of them are preferable to choose for country houses and country houses, others for urban buildings, while others are most suitable for economic buildings. In order to make a choice, you need to familiarize yourself with each roofing material separately.

Metal tile

Considering roofing materials, you can prefer metal, which is made of cold rolled steel with a thickness of 0.4 to 0.5 millimeters. On top, the sheet is covered with zinc, which is protected by polymers. The protective layer is the top layer. The finished product weighs very little, so one square meter can have a mass ranging from 3 to 5 kilograms. Installation works assume compliance with the lower permitted slope of the roof, which is 15 degrees. With minor slopes that do not exceed 20 degrees, it is necessary to carefully seal the joints between the webs. Such roofing materials are laid with an overlap along the length, which should be from 45 to 150 millimeters.

Positive features of metal

Customers choose this covering material because of their longevity: the manufacturer emphasizes that it can be used for 30-50 years. Acquisition of this kind can be considered quite profitable, since for a square meter the buyer will have to pay from 7 to 15 dollars. Installation work is simple enough, the surface after fixing perfectly copes with loads and impacts. When transporting there is no need for a particularly careful attitude, which is also an undoubted advantage.

Onduline characteristics

Considering the roofing materials in the store, you can prefer ondulin, which attracts little cost and environmental friendliness. It consists of sufficiently fine cellulose fibers, which are impregnated with bitumen and polymer additives during production. The second name is the Euro-sphere, and also the aqualaine. In the plant conditions, the canvas is painted with a polymer heat-resistant paint, which can be applied in one or two layers. Each sheet weighs 6.5 kilograms, and also has waves with a height of 3.6 cm. When planning the amount of necessary material for work, it must be taken into account that the length of one web is 2 meters with a width of 0.96 cm. Considering the properties Roofing materials of this type, you should pay attention to the installation technology. The minimum angle of roof slope for the use of ondulin is 6 degrees. If the slope does not exceed 10 degrees, the crate is made solid, with a longitudinal overlap of 30 cm. When working with a slope of 10 to 15 degrees, it is important to equip the crate with the use of a bar between the elements of which will be a distance of 45 cm. If the roof has an angle , Which exceeds 15 degrees, then there will be enough distance between the elements of the crate of 60 cm. For fixation, you should stock up with special nails.

Positive features of ondulin

If you choose roofing materials, the types and properties of it should be known to you. Thus, the lifespan of ondulin is 40 years. However, it must be taken into account that during the period of operation the paint may lose its original brightness. For one sheet of coverage you will have to pay 5 dollars. Perhaps you decide to choose ondulin as a roofing material after you learn that it has excellent water resistance, hygiene, resistance to chemicals, as well as the ability to undergo loads whose mass does not exceed 960 kg per square meter. The light weight of the canvas makes it easy to transport and lay, and in the process of work there will be no difficulties with cutting. To do this, you can use a simple hacksaw designed for working with wood. Ondulin is distinguished by its noiselessness, which is important for private houses.

Negative characteristics of ondulin

Before choosing the material described above, it is worth paying attention to some negative features, as the main one of them can be highlighted flammability. The temperature limit is 110 degrees. After 3 years of operation, it is necessary to be prepared for the fact that mosses will form in areas of poorly lit places. In hot weather, do not plan the repair work of the onduline coating, as it softens and exudes the smell of bitumen.

Weldable roofing materials

Surfacing roofing materials are still known as glass insulation, or waterproofing. Some manufacturers give their own names, but the content does not change much. In the production process, fiberglass, fiberglass or polyester is used. The latter variety is qualitative, but it has a high cost. Fiberglass also has quite good characteristics, whereas the glass fiber can not differ too high quality. The base is poured with oxidized bitumen, into which a modifier is added for durability and elasticity. The latter can be styrene-butadiene-styrene or atactic polypropylene. After that, the polymer is covered, and the top is laid with sand, mica or shale.

Mounting Features

The welded roofing materials are laid with a slope, which should not be less than 11 degrees. If you want to work with a solid foundation made of concrete, wood, flat slate or metal, then the insulation is laid, and the top is covered with waterproofing. At the next stage, a primer or gasoline is applied, which is dissolved in the bitumen. The roofing carpet is laid using a gas burner, it is necessary to start such work from the bottom. The lateral and end overlap must have a width of 10 cm.

Pros of fused materials

Surfacing roofing materials can last up to fifty years, they will have to pay no more than two dollars per square meter. In the process of operation, it is almost unnecessary to take care of the roof, it protects from noise, fire and moisture. Among the positive features can be identified environmental friendliness and absolute harmlessness. Consumers choose this material because of their considerable weight.

Ruberoid for roofing

If you decide to prefer bituminous roofing materials, you can buy a roofing material, which is a soft waterproofing sheet, based on cardboard. The latter is impregnated with all kinds of additives and petroleum bitumen. It will be most convenient to stack it if you purchase the goods in the form of rolls. Use this coating can be both on pitched and flat roofs. Among other things, it acts as a protection of foundations, upper or lower layers of the roof. In the market of the corresponding goods, you can find a simple roofing felt, which is called pergamon and Euroruberoid.

If you use roofing and waterproofing materials in your work , you can prefer a glassine that fits in three or four layers, which guarantees reliable service for 10 years. You can perform these manipulations manually. A weldable ruberoid, which is also called rubemast, is easy to lay down if compared with the above-described variety, while in the rest it has the same quality characteristics.

Membrane flat roofing

Considering the roofing materials, the types and properties of which are described in the article, it is possible to purchase a membrane flat roof, the thickness of which varies from 0.8 to 2 millimeters. It is not environmentally friendly, but it excellently protects from the effects of fire and ultraviolet radiation. You can lay these roofing materials on the roof with any slope, this is due to the elasticity of the membranes.

The base can be fastened in various ways, but the best of them is hot air welding. It is worth noting that for this type of work will require the use of special equipment that can be rented.
