Hiring a Contractor - Pros & Cons
Types of Roofing Materials
Composition Shingle
Commonly known as asphalt shingles, they come in two types: either an organic fiber mat or fiberglass core. Each type is impregnated with asphalt and coated with mineral granules to add color and texture. An adhesive back combined with nails, tacks or staples is the fastening method used. You will most likely find a "good/better/best" selection. Compare warranties (number of years the roof should last) when shopping. Shingles are available in the common 3-tab style or newer architectural designs that replicate other roofing materials such as wood or slate.
Corrugated Sheet
There are two main types: Sheets composed of fiber and impregnated with asphalt are available in many colors (or can be painted). This sheet roofing can be installed over existing roofs of other types. This is one of the easiest roofs to install for a do-it-yourselfer.
Wood
There are two types of wood roof: choose shingles cut to a specific size and smooth finished, or shakes, which are irregular and rough-textured. Wood provides an organic, natural look to your home. However it also requires more maintenance than other options to protect it from the elements. Commonly made of cedar, you also need to keep fire-resistance in mind when opting for a wood roof.
Metal
Metal roofs have returned from the olden days to become a popular roofing option. Once limited to low-slope structures, standing seam steel roofs can now be used on steeper roofs as well. Metal is durable, practically maintenance-free, heat reflective and nonflammable. Installed in sheets, a metal roof will actually dissipate a lightning strike rather than conduct it (a concern left over from the olden days). For real visual impact, a copper roof ages to an attractive patina.
Tile and Slate
These are two of the oldest roofing materials around. They are long-lasting and durable. Their weight requires a reinforced roof structure that can support them. Both can be quite expensive and neither are easy to install.
