The roof protects the house from precipitation, frost and other negative environmental factors. To cover it today it is customary to use different types of materials. It can be hard, soft, profile, flat, roll and piece solutions. Some of them are preferable to choose for dachas and country houses, others for urban buildings, while others are most suitable for outbuildings. In order to make a choice, you need to familiarize yourself with each roofing material separately.
Metal tile
Considering roofing materials, you may prefer metal tiles, which are made from cold rolled steel with a thickness of 0.4 to 0.5 millimeters. From above the canvas is covered with zinc, which is protected by polymers. The top layer is a protective varnish. The finished product weighs very little, so one squarea meter can have a mass ranging from 3 to 5 kilograms. Installation work requires compliance with the lower permissible slope of the roof, which is 15 degrees. With slight slopes that do not exceed 20 degrees, it is necessary to carefully seal the joints between the canvases. Such roofing materials are laid with an overlap in length, which should be from 45 to 150 millimeters.
Positive features of metal tiles
Customers choose this covering material because of its durability: the manufacturer emphasizes that it can be used for 30-50 years. The acquisition of this kind can be considered quite profitable, since the buyer will have to pay from 7 to 15 dollars per square meter. Installation work is quite simple, the surface after fastening perfectly copes with loads and shocks. When transporting, there is no need for a particularly careful attitude, which is also a definite plus.
Ondulin characteristics
When considering roofing materials in the store, you may prefer ondulin, which attracts with low cost and environmental friendliness. It consists of fairly thin cellulose fibers, which are impregnated with bitumen and polymer additives during the production process. The second name is euroslate, as well as aqua. In the conditions of the factory, the canvases are painted with polymeric heat-resistant paint, which can be applied in one or two layers. Each sheet weighs within 6.5kilogram, and also has waves with a height of 3.6 cm. When planning the amount of material needed for work, you need to take into account that the length of one sheet is 2 meters with a width of 0.96 cm. Considering the properties of roofing materials of this type, you must pay attention attention to the technology of installation. The minimum angle of inclination of the roof for the use of ondulin is 6 degrees. If the slope does not exceed 10 degrees, then the crate is made continuous, while the longitudinal overlap should be 30 cm. When working with a slope of 10 to 15 degrees, it is important to equip the crate using a beam, between the elements of which there will be a distance of 45 cm., which exceeds 15 degrees, then a distance of 60 cm between the elements of the crate will be sufficient. For fixing, stock up on special nails.
Positive Features of Ondulin
If you choose roofing materials, the types and properties of it should be known to you. Thus, the life 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. You may decide to choose ondulin as your roofing material after you know that it has excellent water resistance, hygiene, chemical resistance, and the ability to withstand loads that do not exceed 960 kg per square meter. The light weight of the blades makes it easy to transportand laying, and in the process of carrying out the work there will be no difficulties with cutting. To do this, you can use a simple hacksaw designed for working with wood. Ondulin is quiet, 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, flammability can be singled out as the main one. The temperature limit is 110 degrees. After 3 years of operation, you must be prepared for the fact that moss will form in areas of poorly lit places. In hot weather, you should not schedule repairs to the ondulin coating, as it softens and exudes a bitumen smell.
Fusion Roofing Materials
Built-up roofing materials are also known as stekloizol, or hydroisol. Some manufacturers give this material their own names, but the content does not change much from this. In the production process, fiberglass, fiberglass or polyester is used. The latter variety is of high quality, but has a high cost. Fiberglass also has fairly good characteristics, while fiberglass is not very high quality. The base is poured with oxidized bitumen, in which a modifier is added for durability and elasticity. The latter can be styrene-butadiene-styrene or atactic polypropylene. After that it is coveredpolymer, and a topping of sand, mica or fine shale is laid on top.
Mounting Features
Flated roofing materials are laid at a slope that should not be less than 11 degrees. If you have to work with a solid base made of concrete, wood, flat slate or metal, then insulation is laid, and waterproofing is covered on top. The next step is the application of a primer or gasoline, which dissolves in bitumen. The roofing carpet is laid using a gas burner, it is necessary to start such work from below. The side and end overlap must be 10 cm wide.
Pros of weld materials
Laminated roofing materials can last up to fifty years, they will have to pay no more than two dollars per square meter. During operation, it is practically not required to take care of the roof, it protects against noise, fire and moisture. Among the positive features, one can single out environmental friendliness and absolute harmlessness. Consumers choose this material also because of the significant weight.
Roofing material for roofing
If you decide to prefer bituminous roofing materials, then you can purchase roofing material, which is a soft waterproofing sheet made on the basis of cardboard. The latter is impregnated with all kinds of additives and oil bitumen. It will be most convenient to stack it if you purchase the product in the form of rolls. This coating can be applied both on pitched and flat surfaces.roofs. Among other things, it acts as a protection for foundations, upper or lower layers of the roof. On the market for relevant products, you can find a simple roofing material, which is called glassine and euroroofing material.
If you will use roofing and waterproofing materials in your work, then you can prefer glassine, which is laid in three or four layers, which guarantees reliable service for 10 years. You can perform these manipulations manually. The built-up roofing material, which is also called rubemast, is easy to install when compared with the variety described above, while otherwise it has the same quality characteristics.
Membrane flat roof
Considering roofing materials, the types and properties of which are described in the article, you can purchase a membrane flat roof, the thickness of which varies from 0.8 to 2 millimeters. It is not environmentally friendly, but it perfectly protects against fire and ultraviolet radiation. Such roofing materials can be laid on the roof with any slope, this is due to the elasticity of the membranes.
The base can be fixed in many ways, but the best of them is hot air welding. It is worth considering that this kind of work will require the use of special equipment that can be rented.
