Mill Valley Roof Repair, a Mill Valley roofing contractor serving Alto, Cascade, Homestead Valley, Muir Beach, and Strawberry, provides this page to outline the terms that govern our work and your use of this website. By requesting an estimate or engaging our services, you agree to these terms. We keep them plain and honest, because a roof is a big investment and you deserve clarity.
When we start a roof replacement, we begin with a full tear-off. That means we strip the old shingles down to the roof deck, inspect the substrate for rot and decay, and replace any damaged decking. We then install a self-adhered ice and water shield along the eaves and valleys, which is critical in Mill Valley where coastal fog and morning moisture are constant. We use ring-shank nails for every starter course and field course, and we lay staggered courses to keep water from wicking under the shingles. We never overlay a new roof over one that has end-of-life wear, because an overlay hides problems and shortens the new roof's life.
We also handle roof repair for storm damage, leaks, and granule loss. If your shingles are flaking or spalling, we can often mend just the affected area rather than replace the whole roof. For older roofs with widespread cracking or curling, we may recommend a full replacement. We service both residential and commercial roofing, and we use materials that perform well in our mild, wet climate. We can also add ventilation and insulation upgrades to improve energy efficiency, which cuts your heating and cooling bills.
Our estimates are free and itemized. We tell you exactly what the tear-off, materials, and labor will cost, and we do not start work until you approve the scope. We stand behind our work with a workmanship warranty, and we install shingles that carry their own manufacturer warranty. You are responsible for keeping gutters clear and trimming branches that rub the roof, because those cause granule loss and rot. If you have an emergency, like a tree branch through the roof or a sudden leak during a Pacific storm, call us at 628-345-3445. We offer emergency tarping and temporary repairs to stop water intrusion until we can do a permanent fix.
We serve all of Mill Valley, including the neighborhoods of Alto, Cascade, Homestead Valley, Muir Beach, and Strawberry. We know the fog that rolls in from the Golden Gate National Recreation Area and the heavy winter rains that come off Mount Tamalpais. That is why we use corrosion-resistant fasteners and flashing that can handle decades of moisture. We also respect your property. We lay down tarps, use magnetic nail sweepers, and clean up every day. If you have questions about these terms, call us. We are happy to explain anything in plain language.
Yes. We provide a free, no-obligation estimate for any roof repair or replacement. We walk the roof, measure, and give you a written quote.
