Organic asphalt shingles have a paper mat or backing with a layer of asphalt added on top. Fiberglass asphalt shingles contain a mat made of fiberglass with a layer of asphalt added on top. Composition shingles are made from materials such as asphalt or asbestos, tar paper, slate, shake, laminate and wood. The combination of these ingredients improves the shingle's strength.
Slate and cedar roofs look more elegant than composition roofs, but the difficulty of shingle manufacture and installation is reflected in the price. These roofing shingles do have advantages: both are naturally insect resistant, and slate is also fire resistant.
