Services
Composition Shingles
Our composition shingle roofing combines fiberglass and asphalt for lightweight durability with a 40-year warranty. Available in multiple colors and styles, these roofs suit various architectural designs while requiring minimal maintenance. Ideal for Marin County's climate, they offer superior protection against weather elements while maintaining aesthetic appeal for residential properties.
Tar & Gravel Systems
Tar and gravel roofing systems provide cost-effective solutions for flat roofs with up to 30 years of durability. The layered protection reflects UV radiation, reducing energy costs by maintaining cooler indoor temperatures. Our installation includes proper drainage solutions to prevent water accumulation while maintaining budget-friendly pricing for residential and commercial applications.
Wood Shingles & Shakes
Natural wood roofing options include machine-cut shingles for clean lines and hand-split shakes for rustic aesthetics. Treated for fire resistance, these eco-friendly materials offer 30-year durability with proper maintenance. Our installation preserves the traditional appearance while meeting modern safety standards for residential properties in Marin County.
Single-Ply Systems
Single-ply roofing solutions feature thermoset rubber or thermoplastic membranes for commercial buildings. These lightweight, UV-resistant materials withstand extreme weather while offering easy maintenance. Our installations include reinforced seams and proper insulation to ensure energy efficiency and long-term performance for flat or low-slope commercial roofs.
Re-Roofing Services
We specialize in complete roof replacement projects using modern materials while maintaining structural integrity. Our process includes proper tear-off, substrate preparation, and code-compliant installation for all roof types. Customers benefit from improved energy efficiency, enhanced warranties, and updated aesthetics while extending their property's lifespan.
