Asphalt shingles are the most commonly used and among the least expensive of
materials available for steep slope applications. They are very durable and are
available in a wide variety of colors and textures.
Asphalt shingles consist of either an organic (wood fiber or cellulose) or
fiberglass mat which has been saturated with asphalt and covered with colored
mineral granules. In climates where fungus growth is a potential problem,
granules treated with algecide are available. "Self-sealing" shingles have an
additional strip of adhesive on the underside. The adhesive is activated by the
sun's heat after installation and "seals" each shingle to the one below it,
providing extra wind uplift resistance for the roof system.
Shingles were once available in only one thickness, but
today many manufacturers offer shingles where several layers have been
laminated together to produce three-dimensional profiles and appealing
shadow lines. These are known as "dimensional" or "architectural"
shingles.
