How do you fix asphalt roofs

Asphalt-prepared roofings are manufactured in three forms: mineral-surfaced shingles, mineral-surfaced roll roofing, and smooth-surfaced roll roofing. Mineral-surfaced asphalt shingles and roll roofing are composed of roofing felt, made of organic fibers saturated and coated on both sides with asphalt and surfaced with mineral granules on the side to be exposed to the weather.

The other side may be dusted with mica or talc.

Smooth-surfaced asphalt roll roofing is dusted on both sides with fine mineral matter such as mica, talc, or fine sand and is usually lighter in weight than mineral-surfaced roll roofing. Mineral-surfaced asphalt shingles and roll roofing are available in a variety of colors; smooth-surfaced roll roofing is usually black or gray.
