Complete Roof Replacement in Mill Valley

Your old roof has served its time. We remove every layer down to the deck, inspect for water damage, and install a new system built to handle Mill Valley's wet winters and coastal fog. Every job includes ice-and-water shield at valleys and eaves, plus a 50-year architectural shingle. Expect the work to take 3 to 5 days for an average home.

A modified bitumen roof is built in layers — a base sheet, reinforcing fabric, and a top coating of asphalt and polymers. This system handles Mill Valley's wet winters and foggy mornings without cracking or blistering. Your roof stays watertight for decades.

Built for Mill Valley Weather

Tear-Resistant Membrane

The fiberglass or polyester mat in the middle of the membrane stops tears from spreading. Even if a branch scrapes the surface, the waterproof layer underneath stays intact. That means fewer repairs after storms.

Waterproof Seal

The final coating fuses into a seamless, rubber-like barrier. Water runs off completely — no ponding, no leaks. We torch-apply or cold-adhere every seam to ensure no gaps in Mill Valley's heavy rain.

Energy-Efficient Surface

We offer white or light-gray granule caps that reflect sunlight instead of absorbing it. Your attic stays cooler in summer, which lowers your air conditioning bill. Mill Valley homeowners save an average of 15% on cooling costs.

Why Choose Modified Roofing

Quality Material

We use only GAF and Owens Corning modified bitumen rolls. These materials carry a 20-year manufacturer warranty. Every roll meets ASTM D6163 standards for tensile strength and weather resistance.

Fully Insured

Millvalley Roofing carries $2 million in general liability insurance and full workers' comp. We provide proof of insurance before any job starts. You never worry about liability if something goes wrong.

Workmanship Guarantee

We back every modified bitumen install with a 10-year workmanship guarantee. If a seam lifts or a corner peels, we fix it free. That includes labor and materials.
