Challenge: Aging Roof Coating and Desert Exposure

Flat and low-slope roofs in Sedona face intense UV exposure, temperature swings, and monsoon-season moisture. Over time, even a properly installed coating system begins to degrade under these harsh desert conditions.

The existing roof showed signs of aging and weathering, making it an ideal candidate for a maintenance recoat before more significant issues developed. In addition to the roof work, a minor stucco crack required repair to maintain the home’s exterior integrity. The challenge was to properly prepare and reseal all vulnerable areas to ensure long-term adhesion and waterproofing performance.

Solution: Premium Silicone Recoat with Detailed Waterproofing

To restore full protection to the low-slope roofing system, a premium high-solids silicone coating system was installed according to manufacturer specifications. Proper preparation and attention to detail were critical to achieving a long-lasting bond and seamless waterproof barrier.

• Pressure washing the existing roof surface to ensure optimal silicone adhesion
• Resealing vents, flashings, drains, scuppers, roof penetrations, corners, and membrane splits as needed
• Inspecting and resealing exterior scupper joints to prevent water intrusion at transitions
• Installing polyester reinforcement fabric at critical areas for added durability
• Applying Polyglass Polyrbrite 90.1 high-solids silicone coating at 1.5 gallons per 100 sq ft
• Completing a targeted stucco repair with matching paint supplied by the homeowner
• Proper waterproofing of all roof openings and thorough debris removal upon completion

The selected silicone coating provides a seamless, UV-resistant membrane that reflects sunlight and resists ponding water—an ideal solution for flat roofs in Sedona’s climate.

Result: Extended Roof Life and Renewed Peace of Mind

With approximately 3,200 square feet of low-slope roofing professionally recoated, the home now benefits from renewed waterproof protection and enhanced resistance to Sedona’s harsh sun and seasonal rains.

The silicone system creates a continuous, flexible barrier that helps prevent leaks, improves reflectivity, and reduces ongoing wear from UV exposure. Beyond the technical benefits, the homeowner gained confidence knowing their roof was proactively maintained—avoiding costly future repairs and extending the life of the existing roofing system.

Trust & Proof: Backed by Warranty and Manufacturer Standards

This project was completed in full accordance with manufacturer installation guidelines, using a high-solids silicone coating system designed for long-term performance on low-slope roofs.
