To lay roll roofing, you need to prepare your roof surface, apply an adhesive base, unroll the material, and secure it with nails and tar. Roll roofing is a budget-friendly option for flat or low-slope roofs. According to RubyHome, flat roofing costs between $5.50 and $7.50 per square foot, making it one of the most affordable choices for homeowners. This guide walks you through each step to help you do it right the first time.
What Is Roll Roofing?
Roll roofing is a single-layer material made of asphalt-saturated felt or fiberglass. It comes in large rolls that are easy to handle and install. The material is lightweight and flexible, which makes it perfect for DIY projects.
Roll roofing typically lasts 15 to 20 years. According to industry data, flat roofing systems have a lifespan of 20 years on average. It works best on roofs with a pitch of 4:12 or less.

Prepare Your Roof Surface
Start by clearing your roof of debris, dirt, and old roofing material. Use a broom or shovel to remove everything loose. Check for low spots or holes and fill them with patching compound.
Next, inspect the roof deck for rot or damage. If you find soft spots, you may need to replace that section before laying roll roofing. A solid, flat surface is key to a long-lasting roof.
Apply Adhesive and Roll Out the Material
Spread a layer of roof cement or asphalt adhesive across the roof deck using a trowel or roller. Work in sections so the adhesive does not dry out. The adhesive layer should be about one-eighth inch thick.
Unroll the roofing material slowly over the adhesive. Press it down firmly to remove air bubbles. According to IBISWorld, the U.S. roofing contractor industry reached $81.3 billion in 2025, with flat roofing systems remaining a core product segment for cost-conscious homeowners.
Secure and Finish
Nail down the edges of the roll roofing every 6 inches using roofing nails. Make sure nails go through the roofing material and into the roof deck. Seal all nail holes with roof cement to prevent leaks.
Apply a tar or adhesive seam along overlapping edges where two pieces meet. According to the U.S. Bureau of Labor Statistics, roofers earn a median wage of $50,030 per year, reflecting the skill required for proper installation. For a 1,700 square foot roof, installation typically costs between $6,800 and $68,000 depending on material choice and labor.
