A metal roof installation entails strict regulations and a level of standards. The installer needs to have knowledge of basic roofing design concepts and must be able to relate that to their performance. It also requires understanding of why certain fasteners, materials and methods are used. Here are the requirements of a good metal roofing installation:
Uplift
Wind can cause stress to roofing systems by forcefully pulling or suctioning a finished roof upward, a phenomenon known as wind uplift.
A metal roof must be designed to withstand strong wind conditions. This can be achieved by using historical climate data of the area and engineering formulas. With this data, the designer will identify the appropriate fasteners, clips and spacing for the installation. However, the life of the metal roof is in the installer’s hands since they are responsible for the application. A trained and experienced roof repair contractor knows the various wind zones on a roof and understands that those areas may need more fasteners or clips than usual.
Insulation
One of the main functions of an efficient roof is to protect the interior space from temperature changes in the outside environment. For metal roofs, there are two kinds of insulation: rigid and continuous. In some cases, vapor retarders, which are crucial for the prevention of condensation, are applied as well.
The amount of adequate insulation on metal roofs may vary depending on code requirements, climate conditions and structural use.
Energy Efficiency
The roof plays a significant role in the energy efficiency of building structures. It receives interior heat that rises to the underside of the roof and absorbs additional heat from the sun. It also must keep rain, wind and moisture out — while allowing ventilation inside. That is why a lot of residential roofing customers select metal roofing since it has superior ability to maintain the energy efficiency of homes.
