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.
Main roof parts
The main components of the roof structure are:
- rafters;
- crate;
- roof.
Rafters perform the supporting function of the roof. They are hanging and layered. The design is determined taking into account the type of roofing material, the possible amount of snow cover, the pressure of the wind load, the slope and the length of the span.
The lathing serves as the basis for laying and maintaining the roof. If the coating is made of asbestos-cement sheets, sheet steel or tiles, it is made with the same step distance. Solid purlin is used for roll material.
Roof is the main covering that protects the building from precipitation, sun and wind.
Features of additional elements of the roof
In order for the roof to have a beautiful and neat appearance, in addition to roofing material, high-quality additional elements of the roof and facade are needed. The integrity of the coating depends on how well they are selected. The main functions that these roof elements perform are the protection and decoration of the structure. They increase the level of thermal insulation, provide a joint seal, prevent moisture and dust from entering the under-roof space, and also give the building a complete architectural look.
Roofing elements from corrugated board are made of high quality galvanized steel coated with a protective polymer layer. The use of such a protective coating protects them from ultraviolet radiation and corrosion. Parts are made both in standard sizes and according to individual orders. Usually they are selected according to the color and shade of the roofing material. If you correctly and competently install the coating, the reliability and durability of the roof of your house will be guaranteed.
Types and application of additional elements
All roofing elements are selected depending on the type of coating material. Among the additional details, the following can be distinguished:
- fronton bar - designed for joining horizontal surfaces with vertical elements;
- skate - decorates and protects the closing of the roof slopes;
- valley and corners - make it possible to neatly arrange the external and internal corners of the roof;
- decorative elements - domes, wind indicator, spiers -help to create a beautiful and original appearance of the house;
- snow holder - prevents snow from sliding off the roof;
- false-pipe - is a decorating chimney box, which consists of a smooth sheet;
- drainage systems - this system serves to protect the foundation from erosion, and the walls from damage;
- roofing films - a synthetic vapor barrier material that is used to seal the roof and remove the condensate formed under the roof to the outside;
- ventilation elements are designed for natural or forced air extraction from the house;
- roof passages are used for maintenance and repair - special steps, stairs, etc.;
- safety elements are lightning protection and grounding systems.

- skates - these roof elements are laid on the edges of the roof slopes.
How to choose additional elements forroofing
In order to choose and purchase additional elements correctly, some factors must be taken into account. They should be bought together with 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 warranty for additional elements applies only in one case - if they were correctly mounted.
When choosing parts for the roof, be sure to pay attention to the methods of their fastening. You should not buy those elements that are mounted with nails. This will lead to damage to the polymer coating, which will contribute to the corrosion of the product. The quality of the elements is of no small importance. To do this, you need to pay attention to their geometric shape. It should be without bends. If the item has any flaws, it should not be purchased. This indicates a violation of production technology. Don't fall for big discounts. Only high-quality products will give your home a unique finished architectural look and protect it from atmospheric and other phenomena.
