Elastomeric Acrylic Flat Roof Re-Coat and Resurface on a 30-Square Foam Roof in Phoenix, AZ

A homeowner in Phoenix, Arizona chose SUNVEK to re-coat and resurface a large residential flat roof after the existing foam roof showed visible wear, discoloration, and areas needing repair. The project was financed with 12 months of no interest and no payments, giving the homeowner a practical way to restore the roof without delaying needed protection.

The project covered approximately 3,000 square feet (30 squares) across a roof with multiple rooftop details — solar panels, HVAC equipment, parapet walls, skylights, vents, conduits, and low-slope sections — and included power washing, targeted repairs, and a two-coat elastomeric acrylic roof coating system designed to refresh the surface, improve weather resistance, and extend the life of the existing system.

Problem: Weathered Foam Roof With Multiple Rooftop Obstacles

The existing flat roof had surface staining, worn coating, and areas that needed repair before a new coating system could be applied. Discoloration was visible across the roof field, parapet areas were worn, and vulnerable sections had been marked for repair.

The roof’s layout added significant complexity. Solar arrays, HVAC equipment, skylights, vents, parapets, conduits, and rooftop transitions all required careful preparation and detailed coating work so the new roofing surface could protect the home consistently across every section and penetration.

Solution: Power Wash, Repair, Base Coat, and Elastomeric Acrylic Topcoat

SUNVEK restored the roof by power washing the existing surface to remove dirt, debris, and buildup, then making necessary repairs and addressing worn areas around roof penetrations, parapets, and transitions. Once the surface was clean and prepared, the crew applied and back-rolled an elastomeric acrylic base coat at approximately 1 gallon per 100 sq. ft. for consistent adhesion.

An elastomeric acrylic topcoat was then applied at approximately 1.5 gallons per 100 sq. ft. to complete the renewed protective surface. Throughout the application, the team worked carefully around the solar panels, HVAC equipment, skylights, vents, and conduit to ensure complete, consistent coverage across the entire 30-square roof.

Result: Renewed Protection, Better Reflectivity, and Homeowner Peace of Mind

The completed re-coat refreshed the Phoenix home’s large flat roof with a cleaner, more uniform protective surface. The elastomeric acrylic coating improved the roof’s ability to resist sun exposure and weathering while helping preserve the existing foam roof system, and the bright finished surface improved reflectivity to help manage heat in Phoenix’s intense desert climate.

For the homeowner, the project delivered both practical and financial value. The roof was restored before more severe deterioration could develop, and the 12-month no-interest, no-payment financing made it easier to move forward with confidence. Compared with postponing maintenance or relying on spot repairs alone, this re-coat addressed the system as a whole — cleaning, repair, base coat, topcoat, and careful detailing around complex rooftop features — all backed by a 5-year warranty.
