Types of roofing materials

Roof has to fight   with a variety of natural disasters — moisture, wind and cold, each of which has specific requirements for the roof. These factors explain the need for a multi-layer structure, part of which is thermal insulation, wind protection, drainage system, waterproofing,   roofing. The latter protects the multilayer structure and framework, which is designed to withstand it. Each component performs certain functions of the roof, as the material for the roof covering is required to withstand the attack of snow and wind, rain and hail, and be an ornament of buildings.

The main requirements to the roof

For consumers, an important indicator is the strength and durability of the roof, the degree of complexity of installation and the possibility of applying the coating material for complex designs. The weight of the material affects the need for further strengthening of the structure, so choose the cover that carries an additional burden, it is necessary in the planning phase of the building. For many consumers in addition to the protective functions of the roof carries and aesthetic. This defines a huge variety of designs decorating coatings. The performance of each type of coating affects the material that is used as a raw material in its production.

Metal

Types of roofing materials

Today, the most popular roofing material — metal, since it has high strength and durability, light weight and ease of installation. The most common metal roof — steel. Televisions are smooth and wavy leaves and leaves that resemble the traditional tiles. Widely used in industrial and civil construction found galvanized steel. It is characterized by affordability and long life. But for individual building construction is important holistic way, not a role that is played by the roof. The main key to a long service life is the quality of the metal. Today is especially popular metal world's leading manufacturer — Finnish company Ruukki, which produces a coating of hot dip galvanized steel, having a thickness of 0.5 millimeters. This coverage is in addition to the zinc layer polymer coating prevents corrosion and allows to solve a problem with the external design of the roof. Today, such metal roofing company Ruukki offers « turnkey ». This means that the kit includes everything you need for a successful installation. This helps reduce costs through accurate mutual satisfaction of all elements of the roof and thus saves labor costs.

Bitumen

Bitumen is the basis for an entire group of roofing materials. It is applied to the reinforcing layer, it is considered a binder. All varieties similar materials   divided into two main parts — by a modified bitumen and oxidized. Their common feature of — plastic. Oxidation of bitumen improves the ductility of its initial performance and heat resistance. Adding modifier improves the properties of raw materials, while increasing the cost. Usually, they act as polymers, particularly styrene-butadein styrene, increases the durability of the material, its heat resistance and flexibility. Polypropylene affects the stability of the material to high temperatures. The first reinforcing layer determines the strength characteristics of the coating. Recently, the use of cardboard — roofing material, which is subject to decay under the influence of moisture is eliminated. He was replaced come durable base made of glass fiber. A special mechanical stability is ensured by using fiberglass and polyester. Coatings of this group are manufactured in a wide variety. Their plasticity allows them to be used in the construction of flat roofs. The service life of these coatings reaches fifteen years.

A variety of bituminous materials

Other materials that are designed for pitched roofs, are widely used in large-scale construction. For example, « evroshifer » enriched with mineral substances, thermosetting resins and pigments. It is lightweight, does not require complicated installation. Among the basic physical and mechanical properties necessary to allocate a low water absorption, high weather, biological, and chemical resistance. Its plasticity allows it to cover a curved roof with a radius of curvature of more than five meters. This material manufacturers provide guarantee for fifteen years, and its lifetime is fifty years.

Shingles

Roof tiles is considered an attribute of « European » Image property, so every year the manufacturers offer a wide variety of « tile » of different materials, in particular of the bitumen. The coating is carried out by laying the tiles, whose shape is different. Fastening soft tile is performed using the self-adhesive layer or special nails. Boxed version Floor mounted easily, and its repair is to replace the dilapidated parts. Besides bitumen and framework defining the physical and mechanical properties of the coating, shingles different outer layer, often made of basalt spreading. Basalt granules having a zero rate of absorption of moisture, prevents the coating from its impact, and serves as protection against mechanical damage. Depending on the quality of installation depends on the life of the coating components in the proper execution of fifty years. The outer layer of shingles affects the aesthetic appearance of the coating, so most manufacturers are constantly experimenting in search of original designs. Installation of shingles require the use of a solid crates or skin with a special water-resistant plywood. This increases the cost of the work.

The sand and clay

Clay and sand — This material for the production of natural tile. The most famous are two types of tiles — Cement-sand and ceramic. They are characterized by durability, which is achieved due to the high resistance to the external environment. Also they have low heat and sound conductivity. Among the main disadvantage is the high total weight of the roof, requiring additional strengthening bearing structures. The main raw material for the production of ceramic tiles is clay, which requires firing. The result is a material of high frost resistance and durability. For the production of cement-sand tile is taken quartz sand, cement and pigments. Pigment determines the features of the production of   the type of tile-based cement solidification. This makes the technology is not as resource intensive. As a result, for the cement-sand tile is less expensive. From the use of cement tiles dependent feature, over time it increases its strength. Manufacturers take into account the desire of consumers tiles emphasize the individuality of the house, so offer a wide range of hues and forms coatings.

Asbestos

Asbestos sheets are known as slate, used in the creation of pitched roofs. Despite the current debate about the negative effect of asbestos, the use of this material in our country are allowed. It has a relatively light weight and easy to handle, which ensured its wide distribution. In working with slate uses a simple carpenter tools. It is easy to perform. Flame resistance, frost resistance, strength, put slate   along with roofing iron. The use of colored sheeting the roof helps to give a nice finished look. Large selection of roofing materials allows the customer to choose the material with any purchasing power. Over the lifetime of the claimed range, they have the desired characteristics. Among them it is worth noting heat and sound insulation characteristics, durability and resistance to the external environment. Choosing the roofing should be based on the required life of the structure. Often the decisive factor is the aesthetic properties of the coating. Today is still consumer preferences given to tile, so manufacturers try to make it out of any suitable material.
