How Commercial Roofing Differs From Residential Roofing
Commercial roof construction is an endeavor distinct from residential roof installation in a variety of ways. Scale is the most obvious one – some commercial buildings have roofs that seem to take up acres of space! The sheer expanse of a commercial roof can make it more vulnerable to the elements.
Degrees of Slope
Commercial roofing designs use a variety of slopes. The simplest, a flat roof, is composed of three layers. The bottom layer protects against water damage. The next layer up is meant to prevent punctures, and the top layer keeps the other layers from being harmed by the sun’s rays, hail and foot traffic.
It is especially important to implement effective drainage systems on flat roofs. Low slope roofs have a drop of around three inches per foot and are generally composed of the same layers that make up flat roofs. Drainage is also a concern with these roofs. Water becomes less of an issue with steep slope roofs that have a drop of more than three inches per foot.
