Why you can not allow for flaws in the installation of roof nodes from corrugated board

Decking is a universal building material, which, due to its lightness and simultaneous strength, is often used in the process of roofing and installation of fencing. Proper installation of sheets of material provides a high-quality and durable roof covering that is resistant to prolonged exposure to negative environmental factors and mechanical damage.

However, some common shortcomings in the installation of roof units can lead to its failure to fulfill its functions. To protect yourself, you need to familiarize yourself with the main mistakes.

Incorrect installation of connection points

It is important to remember the correct installation of roof units. Knots are the places where the sheets of corrugated board are joined together. In some cases, they are not sufficiently sealed, which also contributes to the appearance of defects on the roof. Nodal elements must be mounted with an overlap that varies within 200 mm. Fasten them with self-tapping screws.

In this case, it is important to competently approach the selection of self-tapping screws. Their length is selected depending on the height of the wave of corrugated board. When mounting, it is strongly recommended that you follow a clear step. The distance between the nodes should not exceed 300 mm.

If the roof is built at an angle, it is worthwhile additionally sealing the joints of the sheets with rubber seals. At the same time, it is recommended to provide for the presence of a small hole that promotes proper ventilation of the roof.

Incorrect material calculation

This error leads to a lack of corrugated board and the appearance between the sheets of cracks. This causes moisture to leak under the crate, condensation, mold and mildew will occur.

Wrong choice of type of corrugated board

Building material is divided into several types, which differ in its thickness and level of resistance to stress. For example, roofs with a small area are not subjected to heavy loads and pressure. Therefore, for the installation of the roof, you can use a thinner wall corrugated board.

If the roof has large-scale dimensions, bearing profile marks should be used. Their main difference from the wall appearance is the presence of additional ribs, giving the overall design greater rigidity.

With proper selection and installation of corrugated board, you can guarantee long years of operation of the roof. However, she will not require restoration and special care.
