Tar & Gravel Roofs
Although both Tar & Gravel and EPDM applied roofs are effective, the biggest problems that our customers run into is over time and harsh weather, these roofs begin to crack and blister reducing their effectiveness.

KM Construction can refurbish your old tar and gravel roof simply by removing the gravel, priming and applying our Polyurthane Spray Foam Roofing System and COOL Elastomeric Silicone Coatings.

Flat roofing also known as Tar and Gravel or Built up roofing is commonly made up of a base of tar paper, covered with liquid tar, embedded gravel with a lose gravel covering. Repairs to Tar and Gravel roofing is very expensive and not always effective in stopping the leaks

When you consider that Tar & Gravel roofs weight in some cases up to 70% more than Spray Foam Roofing, why would you want to add that stress to your commerical or residential building.
