Roofing Panel which is used to cover & protect the roof of a building is typically made of metal, such as steel or aluminum, fiberglass, plastic, or asphalt. It can be installed in several ways, depending on the type of panel & the roofing system being used. It can be attached directly to the roof decking using screws or clips, or can be installed over an existing roofing material such as asphalt shingles. Roofing Panel can also be used as a standalone roofing system.
