Composite asphalt shingle or fiberglass shingles is the most common roofing now in use. It is composed of asphalt shingle impregnated paper with mineral granules coating the exposed surface. Numerous colors and styles are available to enhance the design of your garage. Shingles are easy to install, require little maintenance and are easy to repair.
　　If you are using a drip edge, the starter course goes on TOP of the drip edge at the eaves (bottom) and UNDER the drip edge at the rakes (sides). The starter course applied at the eaves is a standard row of composite asphalt shingle shingles with three inches cut off the tab (bottom) ends. (You could also use a 9 inch wide strip of roll flooring.) These are installed in an inverted position. The tabs face the ridge, the wind seal is down, and the mineral surface is exposed to the weather.
　　Overhang the eave by 1/2 inch and leave a space of 1/16 inch between each asphalt shingle. Nail each starter asphalt shingle with four 12 galvanized roofing nails placed three inches above the eaves - one inch and twelve inches from each end of the asphalt shingle.
