Composite or synthetic roofing shingles are made of a mixture of several commonly used roofing materials, such as fiberglass, recycled paper products, and asphalt. Composite shingles are fire-resistant and don't have problems with moisture, making them very safe and reliable. As an extra incentive, many companies manufacture a shingle that is resistant to mold growth and algae. Also, if damaged, composite shingles can be replaced on an individual basis rather than needing to replace the entire roof. Composite roofing does not crack, split, peel or warp and comes in almost any color, shape, or size, which makes them a highly versatile choice.
