Installing shingles is a big job, but it can be done by a knowledgeable do-it-yourselfer with a good set of tools and the right instructions.
Install the underlayment, metal drip edges and any eaves flashing required by code. Follow the manufacturer’s instructions carefully, as you may need to adjust the application according to the slope of your roof.
Place shingle fasteners 6 1/8 inch from the bottom edge of each shingle and 1 inch from each end. Follow the manufacturer’s instructions carefully, and use the recommended nail patterns for the slope of your roof. You may also want to use asphalt roof cement to secure your shingles, depending on the roof’s slope and the manufacturer suggestions.
Apply the shingles over the prepared roof deck. Start at the bottom of the roof and work across and up. This will blend shingles from one bundle into the next and minimize any normal shade variation. Refer to the course application suggestions in the manufacturer’s instructions for further details on spacing and offsetting shingles. Fasten each shingle securely.
Pay special attention to the manufacturer’s suggestions about step flashing and hip and ridge application to make sure your shingle project has a finished look.
Safety is a special concern when working on a roof. If at all possible, perform repairs when the roof is dry. The roof surface may be slippery, especially when wet or icy. Use a fall protection system when installing. Wear rubber-soled shoes and walk with care.
Secure the area below work materials on the roof to prevent injuries from sliding materials.
Handle roofing materials with care as some may contain dangerous chemicals. Follow the warning labels on the manufacturer's instructions carefully.
