How We Install Modified Bitumen

We start with your roof deck. Once the deck is fully cleaned and inspected, we add insulation to improve the R-value of your commercial building. Next, we prepare the surface for a two-ply system. We may need to remove existing roofing materials to prepare the surface for safe and effective installation.

Modified bitumen systems use a reinforced roof membrane made from rubberized or polymeric asphalt. This base layer is applied with a torch or mop. It’s a complex process that’s best left to experienced professionals. Improper installation can create leaks and cause injuries.

Next, we add the cap layer to seal your flat roof. The cap sheet has a granulated surface similar to asphalt shingles. This surface reflects UV rays, creates a waterproof surface and is a cost-effective system. It can be used on a flat roof or as a repair process for low-sloped roofs with asphalt shingles.

Repairing modified bitumen follows the same basic steps. A professional team is required to install or repair this roofing material; otherwise, you may not receive a fully waterproof surface. Work with a leader in your area to enjoy a full-service installation, repair and maintenance program.
