Asphalt shingles are a popular roofing material because of their durability and weather resistance. They often come in 36-by-12-inch wide strips, which consist of three “tabs.” Each three-tab strip has a layer of adhesive that binds to the layer below.
Many homeowners choose asphalt shingles because they’re affordable and easy to install. This residential roofing material comes in a variety of colors and designs, making it easy to find an option that complements your home’s design.
The deck supports the whole roofing system; the other components of the roof are all installed on top of the deck. Materials used for the deck vary, but most homes choose OSB (oriented strand board) or plywood. Other materials, such as polystyrene, concrete or metal, are also available.
Also known as slope, roof pitch is the degree of incline expressed as the ratio of the rise of the roof to the span. Roof pitch varies by design and function; for instance, some homeowners are switching to flat roofs because of their functional layout. Contrary to popular belief, flat roofs are not completely flat; they’re low-sloped so they can shed water.
Felt, a durable paper saturated with asphalt, is the most common roof underlayment material, with synthetic types or rubberized layers alternative options. The underlayment provides an extra layer of water protection in case moisture slips through broken or torn shingles.
