Composite roofing is cheaper than natural wood or stone, but still more expensive than asphalt shingles. The longevity of the material should also be taken into account as well as the upfront cost of the materials and installation. Composite roofing costs between $400 and $1,100 per 100 sq. ft. installed, whereas asphalt cost about $350 and slate can go as high as $1,600.
