Expert Roof Replacement in Mill Valley

Full-Service Roof Replacement

We remove your old roof down to the deck, inspect the wood structure, and replace any rotted sections. Then we install new underlayment, flashing, and your chosen shingles or metal panels. A typical 2,000-square-foot roof takes 3 to 5 days to complete.

Your roof replacement starts with a thorough inspection of your Mill Valley home. We measure every slope and check for water damage or rot before removing old layers. Our crew works efficiently to install your new system, minimizing disruption to your daily life.

Advantages

Tear Resistant

Our modified bitumen membranes withstand heavy rain and wind typical of Marin County winters. The reinforced fabric resists punctures from falling branches or foot traffic during maintenance. This durability means fewer repairs over your roof's 20-year lifespan.

Waterproof

We apply a seamless waterproof layer that protects your Mill Valley home from leaks even during the heaviest storms. The torch-applied or self-adhering membrane bonds directly to the deck, eliminating seams where water can penetrate. This system handles standing water on low-slope roofs common in local craftsman homes.

Energy-Efficient

A white or light-colored modified roof reflects up to 80% of sunlight, reducing your attic temperature by 30 degrees on summer days. This cuts cooling costs by 15-25% during Mill Valley's warm months. Your home stays more comfortable without overworking your HVAC system.

Why Choose Modified Roofing

Quality Material

We source modified bitumen from top manufacturers like GAF and Owens Corning, ensuring consistent thickness and UV resistance. Each roll meets ASTM standards for tear strength and flexibility. You get a roof that performs in Mill Valley's coastal climate for decades.

Fully Insured

Our crew carries general liability and workers' compensation insurance covering up to $2 million. We provide proof of insurance before any work begins. This protects your property and gives you peace of mind during the project.

Guarantee

Every modified roof we install includes a 15-year workmanship warranty plus the manufacturer's material warranty. If a leak develops from our installation, we fix it at no cost to you. This guarantee covers labor and materials for the full term.
