Stinson Beach Flat Roof Replacement Marin County Insulating Foam Roof

Stinson Beach Flat Roof Replacement

Stinson Beach flat roof replacement projects require roofing systems designed for the demands of the Marin County coastal environment. This project features a high-performance insulating spray polyurethane foam (SPF) roof system that delivers seamless waterproofing and continuous thermal protection.

The existing flat roof surface was carefully prepared to ensure proper adhesion of the new system. Perimeter metal was removed and replaced with custom-fabricated copper edge metal, selected specifically for its resistance to corrosion in salt-laden coastal air.

Insulating Foam Roof System with R-10 Continuous Insulation

This Stinson Beach flat roof replacement meets California’s 2022 Energy Code requirements with R-10 continuous insulation. The system was achieved by applying 2.8 lb density spray polyurethane foam at an average thickness of approximately 1.5 inches. This insulating foam roof layer forms a fully adhered, monolithic surface—eliminating seams, improving energy efficiency, and preventing water intrusion across the flat roof.

Silicone Coating and Gravel Surface for Coastal Protection

A primer was applied where required, followed by a premium gray, high-solids silicone coating installed per manufacturer specifications. This coating provides UV resistance, weatherproofing, and long-term protection in a coastal climate. For added durability and aesthetics, a ¼-inch gravel layer was installed.

Class A Fire-Rated Flat Roof System with Warranty

The completed system delivers a Class A fire-rated flat roof—engineered for long-term durability, energy efficiency, and reliable performance in the coastal conditions of Stinson Beach, and backed by a comprehensive warranty.
