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.
Organic asphalt shingles have a proven track record.They are softer and easier to work with,more tear resistant,typically thicker and can hide minor imperfections in your roof deck.However fiberglass shingles have a higher fire rating and are more resistant to heat and curling.I prefer fiberglass.
