Expert Mill Valley Roofing Contractor for Your Home

Full-Service Roofing Contractor

We handle roof replacement, repair, and installation for all Mill Valley home styles. Our team uses premium materials like asphalt shingles, metal roofing, and tile to match your home's architecture and our coastal climate. Every project includes a thorough roof inspection to catch water damage early.

Your roof replacement starts with a thorough inspection of your Mill Valley home's structure. We'll then remove old materials, repair any water damage to the decking, and install your new roofing system. Expect a clean job site each evening and a final walkthrough you'll feel good about.

Advantages

Tear Resistant

Modified bitumen roofs handle Mill Valley's coastal winds and rain exceptionally well. The reinforced layers resist tearing from falling branches or foot traffic during maintenance. This durability means fewer repairs over your roof's 20-year lifespan.

Waterproof

A properly installed modified bitumen system creates a seamless waterproof barrier. The torch-applied or self-adhering layers bond directly to your roof deck, preventing leaks even around vents and chimneys. Your attic stays dry through the wettest Northern California winters.

Energy-Efficient

Light-colored modified bitumen membranes reflect solar heat, reducing your home's cooling costs by up to 15% in summer. Combined with proper insulation, your Mill Valley home stays comfortable year-round. You'll notice the difference on your PG&E bill.

Why Choose Modified Roofing

Quality Material

We source our modified bitumen from GAF and Owens Corning, two manufacturers with decades of proven performance. Each roll meets ASTM standards for tensile strength and weather resistance. Your roof carries a manufacturer-backed warranty for added peace of mind.

Fully Insured

Millvalley Roofing carries $2 million in general liability insurance and full workers' compensation coverage. We provide proof of insurance before any work begins. Your property and our crew are protected on every job.

Guarantee

Every modified bitumen roof we install comes with a 10-year workmanship guarantee. If a leak appears from our installation, we fix it at no cost to you. That's our promise, backed by 15 years serving Mill Valley homeowners.
