Roll roofing is an asphalt and fiberglass-based material used in roofing applications. The material is 36 inches wide, so one row takes the place of three courses of asphalt shingles, making it much easier to install. The preparation needed to install roll roofing is the same as asphalt shingles. The roof must first be dried in, using a layer of felt roofing capped with an appropriate type of drip edge. Because of its ease of installation, Owens Corning roll roofing is ideal for the novice roofer.

Installing Valleys
If your roof has valleys, they need to be addressed before installing the rows of roofing. A common method used by roofers is to first center and secure an 18-inch strip of roofing the length of the valley, followed by a strip that is 36 inches wide. The strips are secured by driving nails 3/4 inch from the edges, spaced every six inches. Ends of roll roofing that fall in the valleys are trimmed 1 inch from the valley center, using a utility knife and straightedge. The ends of each row of roofing are folded back to allow room to apply a 6-inch band of roofing cement before they are nailed into place every three inches along the edge of the overlap.
Installing Rows
Rows of Owens Corning roll roofing are installed starting from the bottom. Most roofing contractors snap a chalk line 35 1/2 inches from the bottom edge of the roof to act as a guide. The first row of roofing material is then rolled out and aligned with the chalk line. It is secured to the substrate by driving roofing nails 3/4 inch from the edges, spaced every three inches along the bottom and sides of the material. The roofing nails must be long enough to penetrate the roof deck at least 3/4 inch. After snapping another chalk line two inches downward from the top of the previously installed row, roofers apply a 2-inch band of roofing cement before installing the next row.
Butt Joints
Attaching an additional piece of the Owens Corning roll roofing to extend the length of a row is called a butt joint. This not only accommodates large roofs that might have a run longer than the length of the rolled roofing, but also eliminates waste by using up shorter pieces of the material. Butt joints require applying roofing cement under the 6-inch overlap before securing the joint with roofing nails. Butt joints are always staggered between rows to avoid placing them atop one another.
Sealing Vent Stacks and Roof Peaks
Vent stacks are sealed by attaching a 12-inch square of roofing material around the pipe, using roofing cement. A hole is cut in the center of the square to accommodate the size of the pipe. The 12-inch square of material is covered by a row of roofing that is notched or cut to allow it to slip over the pipe. Roof peaks or crowns require a 12-inch strip of material cut to the length of the peak. A chalk line is snapped 5 1/2 inches from the point of the peak on each side of the roof, when applicable. A 3-inch band of roofing cement is applied just above the chalk line along the entire length of the peak. A 12-inch piece of roofing material is cut to length and centered over the peak. Roofing nails driven every three inches along both edges secure the strip to the roof.
