Traditionally flat roofs will be the go-to style of roofing for commercial buildings, and just as the name suggests, the roofs themselves lay flat over the top of the building. When it comes to flat roofs, what is important to be aware of first is always that pretty much all in the roofing systems use what`s known as Membrane Roofing. This only denotes which a material is used to move water off the roof.
