Flat Roof Coating & Waterproofing
Mastic, liquid rubber, and silicone coatings can extend the life of a sound roof or seal a small, localized leak — done right, with reinforcement, not just brushed on and hoped for.
How a Coating Repair Is Actually Done
The area gets prepped first — loose mastic, granules, and debris scraped away, since a coating applied over loose material won’t bond. An asphalt-based primer often goes down first to lock in remaining dirt and give the coating a clean surface to grip.
Coating is applied at a specific thickness: too thick and it cracks as it cures, too thin and it won’t hold. For anything beyond a pinhole, a fabric reinforcement layer gets embedded in the coating — it works the way rebar works in concrete, turning a repair that lasts a year into one that lasts five to ten.
Black Mastic vs. Silicone vs. Liquid Rubber
Different products suit different conditions. Black mastic-based systems are often preferred ahead of wet weather; silicone systems handle ponding water and UV exposure well long-term; liquid rubber coatings offer flexibility across temperature swings. We’ll recommend the right system for your specific roof and situation rather than defaulting to one product.
Frequently Asked Questions
Can a coating fix a roof that’s actively leaking?
For a small, localized leak with a sound underlying roof, yes. For widespread membrane failure, a coating is a maintenance tool, not a substitute for repair or replacement.
How long does a roof coating last?
It depends on the product and application, but a properly applied, reinforced coating system commonly holds up for several years before needing recoating.
