Note : The roof covering should be installed as soon as the sheathing is in place to keep the building dry and to provide durable, water-resistant protection. The choice of roofing materials may be influenced by cost, appearance, local code requirements or local preferences. Asphalt shingles are commonly used on pitched roofs. Prefinished metal, galvanized steel or aluminum roofing is als common in some regions. At normal roof pitches, metal roofs will generally shed snow, a desirable characteristic in heavy snowfall areas. Roll roofing, wood shingles, hand-split shakes, sheet metal and concrete or clay tile are also used. Built-up roofing with a gravel topping or cap sheet is usually used for low-slope roofs.
