Built-up roofing is used for commercial flat roofs as well as for residential buildings worldwide. Several alternate layers of felt materials bound with bitumen are used to create the desired number of piles for the structure. Bitumen acts as an adhesive and helps to hold everything together. Then, gravel, smooth asphalt, or other materials are embedded into the top layer. A surface coating can also be applied to reduce the effects of harmful UV rays.
