Asphalt shingles 

Asphalt shingles are one of the most common types of roof systems for steep-slope roofs.

They come in two types: fiberglass and organic. Organic consists of paper saturated with asphalt to make it waterproof with a top coat of adhesive with embedded ceramic granules. Organic shingles weigh more so they have better blow-off resistance. Fiberglass shingles have a glass fiber mat coated with asphalt that contains mineral fillers. It also contains a top coat of adhesive with embedded granules.

Ceramic granules protect the shingles from the sun, and also provide good aesthetics. Shingles come in a variety of colors. Shingles are also very cost effective.

Roof shingles are produced in a single layer (3-tab shingles) or multiple layers (dimensional shingles because they have a 3-dimensional appearance.) Both contain a strip of adhesive that is activated by the sun and seals each row. The strip also provides wind uplift resistance.

Warranties for shingle roofs range from 10 to 50 years. A semi-annual inspection is recommended maintenance to check the for roof system problems. Penetrations in the roof should be checked for deterioration. Shingle roofs are recommended for residential roofs with a minimum 7 degree slope where the eave is 33 feet high or less.
