There are many different types of flat roofing systems that you can consider investing in. As a business owner, you will want to make sure your building is properly protected from the elements, so it’s important to talk to exemplary Dallas commercial roofing company professionals to figure out which type to choose. However, regardless of the roofing system you choose, the basic elements of a flat roof remain roughly the same.
As in the case of sloped roofing, a flat roof has components such as flashing, insulation and a supportive structure on top of which the main roofing material is added. That is called the structural deck, and unlike in the case of most sloped roofing systems, it is designed, together with the load bearing supportive structure, to distribute the weight of the roof towards the walls.
The flashing is only focused on the edge and corners of the roof as well. As in the case of sloped roofs, it has the task of preventing water from leaking between the wall and the roof.
The thermal insulation layer also goes together in most roofing systems with a thin vapor control layer, which helps reduce the onset of condensation. Since flat roofs are usually too simple in their construction to feature complex venting, this layer is designed to especially work to prevent condensation from becoming a problem.
