Roofing nails for first layer.

Drive nails at high points on the underlying roof the bottoms of the shingles. Fasten drip edge on eaves with galvanized nails and a hammer about 12 inches. Nail metal drip edge flashing which bends over the roof and down the edge of the facing board on all roof edges. Bring the ridge edges together with a ridge capping layer.

Paint a thin layer of adhesive over the first felt layer. For a slightly sloped roof use the concealed nail method shown. Ensure the felt remains even and straight as you work. Using galvanised clout nails nail down the first layer of felt.

Applying roofing felt first will better protect the sheathing against condensation as well as against leaking. The first bituminous membrane sheet should then be positioned onto the roof before being secured to the surface typically using a nail gun. Select a length of roofing nails that penetrates completely through the new layer of shingles existing layer and the wood roof deck. The membrane used must have a polyester carrier to ensure good tensile strength.

Apply the shingles to all roof planes ending a row of shingles at the top of the plane which is the ridge or peak and cut to follow the profile of any outside corners. At the eave and the rake install u shape drip edge flashing made for reroof jobs. It s best to start nailing in the center and work out from there. If the roof is sloped you can use the exposed nail method.

Roll roofing is often installed over bare wood sheathing or sheathing that has been painted with a primer. The two pieces should meet neatly at the corners. Install the eave piece first then the rake piece over it. The first layer of modified bitumen is then laid over the membrane before being cut to size to fit the surrounding area.

You can either use special shingles called ridge shingles or cut a number of regular shingles into 3 tabbed equal pieces and bend each so they fit snugly on the roof peak and nail them into place.
