FlatRoof CoatingSystems
Flat roof coating is a silicone membrane spray-applied over an existing commercial low-slope roof to eliminate ponding water, seal seam failures, and restore waterproofing integrity. Applied over TPO, EPDM, modified bitumen, built-up roofing, or concrete without tear-off. Manufacturer warranties to 30 years.

What we can
restore.
If your deck substrate is listed, this service is a candidate. If it's not — or if moisture content exceeds 30% by volume — we'll tell you that too.
No surprises.
No pressure.
Just documented work.
Infrared moisture survey and visual inspection identify ponding zones, seam failures, and substrate condition. Restoration candidacy confirmed in writing.
Roof cleaned, active seam and flashing failures reinforced with fabric-embedded silicone. Ponding zones receive pre-treatment for maximum adhesion.
Full-surface silicone coating spray-applied at manufacturer-specified DFT. Ponding zones receive additional mil thickness. Rain-safe in 15 minutes.
Post-installation thermal scan confirms complete surface coverage. Manufacturer warranty issued for 10, 20, or 30 years.

Per-square-foot pricing for Flat Roof Coating. Compared side by side with full-replacement baselines from 200+ projects.
Flat roof replacement typically runs $10–18/sq ft for single-ply systems. Silicone coating delivers equivalent waterproofing at 25–45% of that cost.

Common questions
about this service.
Pulled verbatim from assessment calls on this specific service.
01Does flat roof coating work if my roof has standing water?
Yes. 100% silicone is the only coating chemistry rated for indefinite ponding water.
02How is flat roof coating different from flat roof repair?
Repair addresses individual failure points: a failed seam, a damaged flashing, a punctured membrane. Coating replaces the entire waterproofing layer in place with a new system that carries its own manufacturer warranty. For roofs with widespread seam fatigue, UV degradation, or chronic ponding, coating is the right scope. For a single leak on an otherwise sound roof, repair is faster and cheaper.
03Can flat roof coating be applied to any substrate?
Silicone coating bonds to TPO, EPDM, modified bitumen, built-up roofing, and concrete without primer on clean surfaces. Metal flat roofs use a dedicated metal coating system with an adhesion primer. Candidacy depends on wet insulation levels and deck integrity, confirmed in the written infrared moisture survey before scope commitment.
04How long does commercial flat roof coating last?
Manufacturer warranty tiers run 10, 15, 20, or 30 years. The term is a function of dry film thickness (25 mils minimum for 15-year NDL, 30 mils for 20-year NDL), maintenance schedule, and certified applicator status. At warranty end, the system is recoatable for another full term with no tear-off.
05Does flat roof coating qualify for ENERGY STAR and utility rebates?
White silicone flat roof coating achieves 80 to 90% initial solar reflectance and SRI above 100, exceeding ENERGY STAR commercial low-slope roof thresholds. Major U.S. utilities (APS, SRP, ConEd, Dominion, Duke Energy) offer commercial cool-roof rebate programs. We provide the documentation required for the rebate application.
