Flat roofing is a different ballgame than traditional pitched residential roofing. From the materials to the installation procedures, everything is different – including the expertise needed. In flat roofing, the installers’ skill is just as important as the roofing material you choose. Poor installation leads to pooling of moisture that inevitably causes leaking. You also need to think about biannual roof maintenance when you have a flat roof. This can help you avoid costly repairs down the road.
