The structural “skin” of a roof over which roofing in felt paper or base sheet is applied. Most new homes have decking made of plywood. There are four main types of decking commonly used on residential roofing projects:
A framed small roof that projects through the sloping plane of a roof.
Application of asphalt roofing such that the lapped portion is at least two inches wider than the exposed portion, resulting in two layers of roofing material over the deck.
A pipe for draining water from roof gutters.
A non-corrosive, non-staining material used along the gable, rakes or edges to allow water run-off to drip clear of underlying construction.
Application of giant individual shingles with the long dimension parallel to the eaves. Shingles are applied to overlap adjacent shingles in each course as well as the course below.
