Expert Roof Replacement in Mill Valley

Modified Bitumen Roofing

Your flat or low-slope roof needs materials that handle Mill Valley's wet winters and fog. Modified bitumen offers a tough, multi-layer membrane that resists ponding water and UV damage. We torch-apply or self-adhere each layer for a seamless, watertight barrier that lasts 20 to 25 years.

Your new roof starts with a thorough inspection of your current structure. We measure every slope and check for water damage in the sheathing. Then we present a clear timeline and a fixed price — no surprises.

Built to Last

Tear-Resistant Underlayment

We install a heavy-duty synthetic underlayment that withstands foot traffic and high winds. This layer adds a second defense against rain before it ever touches your decking.

Waterproof Integrity

Ice and water shield goes into every valley, eave, and penetration. In Mill Valley’s wet winters, this step stops leaks before they start. Your attic stays dry, and your insulation stays effective.

Energy-Efficient Materials

Cool-roof shingles reflect more sunlight and absorb less heat. Your home stays cooler in summer, and you may see lower energy bills. We’ll help you choose the right color and rating for your home.
