Basic and additional elements of the roof

The roof is an important element of any structure.There are many types of this design. The choice is influenced by a number of factors - architectural requirements, geographical location, climatic conditions. Regardless of the type and configuration, the roof includes basic and additional elements.

Basic roof parts

The main components of the roof structure are:

• rafters;
• crate;
• roof.

The rafters perform the load-carrying function of the roof.They are hanging and padded. The design is determined taking into account the type of roofing material, the possible size of the snow cover, the pressure of the wind load, the slope and the length of the span.

The lining serves as the basis for laying andsupporting the roof. If the coating is made of asbestos-cement sheets, sheet steel or tiles, it is manufactured with the same step distance. Solid crate is used for roll material.

Roofing is the main covering, which protects the building from precipitation, sun and wind.

Features of additional roof elements

In order for the roof to be beautiful and tidyappearance, except for the roofing material, we need quality additional elements of the roof and facade. The integrity of the coating depends on how well they are matched. The main functions that these roof elements perform are protection and decoration of the structure. They increase the level of thermal insulation, provide a joint sealing, prevent the ingress of moisture and dust into the under-roof space, and also give the building a complete architectural appearance.

Elements of the roof made of corrugated board are made fromGalvanized steel of high quality, covered with a protective polymeric layer. The use of such a protective coating protects them from ultraviolet irradiation and corrosion. The parts are made both in standard sizes and on individual orders. Usually they are selected according to the color and shade of the roofing material. If correctly and correctly to establish a covering, reliability and durability of a roof of your house will be guaranteed.

Types and application of additional elements

All elements of the roof are selected depending on the type of coating material. Among the additional details can be identified the following:

• lining carpet - used for leveling the surface and additional waterproofing, laid when installing flat roofs;
• curtain rod - serves for laying the first row of roofing;
• carpet valleys - used for finishing joints, made of polyester;
• skates - these elements of the roof are laid on the edges of the roof slopes.

How to choose additional elements for the roof

To correctly choose and purchase additionalelements, it is necessary to consider some factors. Buy them along with the roofing material in one store and from one manufacturer, which will allow you to purchase parts of the same color and shade. The manufacturer's guarantee for additional elements is only distributed in one case - if they have been correctly assembled.

When selecting the details for the roof, you mustto pay attention to methods of their fastening. Do not buy those elements that are mounted using nails. This will lead to spoilage of the polymer coating, which will contribute to corrosion of the product. Of no small importance is the quality of the elements. For this, it is necessary to pay attention to their geometric shape. It should be without curvature. If the item has some flaws, it should not be bought. This indicates a violation of production technology. Do not even give in to significant discounts. Only high-quality products will give your house a unique completed architectural look and protect it from atmospheric and other phenomena.
