Also, you must consider cost, durability, fire resistance, ease of maintenance and manufacturer's warranty. The organic kinds have a base of felt made from wood and paper. They are attractive, widely available, durable and easy to install. Fiberglass base shingles are as economical and as easy to use as organic base but they can last five to 10 years longer because they don't absorb water, so they resist warping and cracking better. Wood roofing, although time consuming to install, is naturally beautiful and can give your home a rugged outdoor look.
Shingles are usually sawn and have a smooth, finished appearance.
Shakes are usually split first and then sawn to a taper on their backs. Because they are split, the face has a rough texture. Flammability is a big worry. Fire retardants can help reduce, but do not eliminate, this danger. Untreated wooden shingles are prohibited in certain areas, so check your local building codes.
