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.
