How To Install Roll Roofing On A Flat Roof
Roll roofing is a continuous sheet of roofing material composed of multiple layers. If you have a flat roof, you'll install roll roofing in horizontal strips that overlap each other. The following steps show how to perform this procedure if you're proficient in roofing repairs.
Step 1. Prepare the roof.
Ensure that the outdoor temperature is above the minimum needed to install your roll roofing. This type of roofing often cracks if you try to unroll it when the temperature is cold.
Remove any loose objects from your roof such as sticks or stones. These objects can eventually poke through your roofing material.
Step 2. Install the starter strip.
Cut a strip of roofing material to a width of about 18 inches. This first strip is commonly known as the starter strip.
Apply a two-inch layer of roofing cement along the eave of a roof surface on your house. Place the starter strip so that its bottom edge overhangs the eave by about 1/2 inch. Flatten the starter strip down against the roof with a roofer's roller to remove any air gaps between the roof and the strip of roll roofing.
Drive roofing nails along the edges of the starter strip at three-inch intervals. Cover the seams and edges of the roll roofing with roofing cement. Use a utility knife to trim the starter strip's overhang, so that it's now flush with the eave.
Step 3. Lay the remaining strips.
Snap a chalk line onto your starter strip about two inches below its top edge. Cover the starter strip above the chalk line with a layer of roofing cement. Place the next strip of roll roofing so that its bottom edge is on the chalk line.
Nail the strip into place with roofing nails, and cover the seams with another layer of roofing cement. Repeat this step as needed to cover the entire roof surface with overlapping strips of roll roofing. Cover the other roof surfaces of your house in a similar manner.
Step 4. Cover the peaks.
Cut a one-foot wide strip of roll roofing, and fold it over a ridge on your house. Nail it into place and cover the seams with roofing cement. Repeat this step to cover the remaining hips and ridges on your roof.
