Composition roofing, usually called asphalt shingles, is the most common roof used on houses. It’s lowest in cost and easiest to install.
Characteristics:
-
- Cellulose or fiberglass mats coated with asphalt and granules
- Many colors available; lighter colors reduce cooling costs
- Lightweight with flat profile
- The heavier the shingle, the longer it will last
- Algae-resistant granules available for warm, humid climates
Laminated shingles are thicker and heavier than composition roofing. Multilayer panels produce three-dimensional profiles and shadow lines. Characteristics:
-
- Fiberglass mat instead of cellulose core
- Has a shake-like profile
- Greater fire and wind resistance than composition
- High-end products weigh up to 450 pounds per square
- High-end products last 40 to 50 years
