DIY: The Proper Method of Installing Asphalt Shingles on the Roof
Due to the issues involved with improper installation, such as leaks and water damage, many people rely on professionals to install roofing, such as asphalt shingles to their home. If you want to install the asphalt shingles on the roof of your home yourself though, you can do so using the techniques recommended by experts in the field. If you follow the proper method of installing asphalt shingles on the roof, you should avoid the problems associated with a bad installation.
Place roofing felt at the edge of the roof, so that it hangs over by about 1/4-inch, and unroll the felt along the eave. Go across the eave in one long strip. Staple the felt to the roof at 12-inch intervals around the perimeter of the felt.
Install the first row of shingles on top of the felt, leaving one to two inches of the first shingle hanging off the side and bottom edge of the roof. Place each shingle so that it lines up with the edge of the single before it and secure the shingles with four to six roofing nails.
Lay another row of shingles right on top of the first. Begin the first shingle so it hangs off the side of the roof by approximately six inches though, so that the seams don't line up with the seams below. Nail the shingles in place.
Install another row of roofing felt so it overlaps the top 10 or so inches of the first row of shingles. Use staples to attach the felt. Then, lay the second row of shingles on top of the felt, overlapping the top of the first row of shingles by approximately 16 inches, and secure with roofing nails.
Go up the entire slope of the roof, laying the final row so the top is roughly two inches from the roof's peak. Then, install shingles on the other side of the roof using the same installation procedure.
Bend asphalt shingles over the roof peak so that each shingle is mostly centered with an equal amount of shingle on both sides of the peak. Secure the shingles with at least two nails on each side. Then, lay the next shingles along the peak so that they overlap the shingle before by about an inch, and nail into place.
Cover the edges of the shingles at the peak, as well as the heads of the nails that you used to secure the shingles with roofing cement. Once the peak is finished, return to the edges of the roof and trim down the edges on both sides of the roof, so that no shingles extend over the edge of the roof more than 1/4 inch.
