Asphalt shingles are the most commonly used roofing material. They are economical, versatile, and work well on steep-sloped roofs. Asphalt shingles require little maintenance and they are sunlight and weather resistant. They are also compatible with many different kinds of flashing and edging products.
There are three basic types of wood roofing products which include hand-split shakes, taper-sawn shakes and wood shingles. Wood shake and shingles provide an elegant natural look. There are so many variations in the color and cut of the wood that no two shake roofs will ever be the same. The best shakes come from large old cedar trees. Wood roofs do require routine maintenance. They need to be cleaned periodically to remove tree debris, moss or fungus. Additionally, wood shingles should be treated with wood preservatives on a regular basis to limit the weathering effects of moisture. This is also necessary to slow the growth of molds, moss and fungi. For further protection, wood roofs can be treated with a fire retardant to reduce the chance of fire.
