Wood or asphalt- composition shingles are the most common roofing material used in residential and other “Steep” and “sloped” applications” worldwide.
Shingles are made of carrier sheets of organic or fiberglass material, coated with asphalt, and granulated in
a wide array of colors. Some asphalt shingles are made to look like wood shingles. Many shingle manufacturers have products that meet new code requirements for reflectivity. Some shingles do not meet these new standards yet. Check with your professional roofing contractor for specifics information about city, county and national code requirements for roofing.
