Roofers FAQ:What is included when professionals install a roof?
The roofing system is comprised of the rafters, decking, underlayment, roofing material, flashing, gutters and downspouts. Each one of these elements must be properly installed and maintained in order for the roofing system to perform its best and last as long as it was intended to. Some professionals include the attic and its insulation as part of the roof system.
