Roofers in Mill Valley, CA
Roofing in Mill Valley, CA comes down to three things: old housing stock, steep terrain, and a marine climate that keeps moisture in play year-round. Most homes here were built between the 1940s and 1970s, which means composition shingle roofs at or past their expected lifespan, valley-flashed chimneys that leak after heavy winters, and slopes that make every job slower than the flat lots over in Corte Madera. We do repair, replacement, and new roof installation here, and we quote every job with a written price before any work starts. Call (325) 246-5075 for a free estimate.
Why Mill Valley Homes Are Different
Mill Valley sits in a bowl of redwood canyons and ridgelines, which means two things for a roof: shade and moisture. Redwoods drop needles and bark that hold water against shingles; north-facing slopes in areas like Homestead Valley and Blithedale Canyon can stay damp for weeks after a storm. That constant moisture is what turns a small flashing gap into rot, moss, and interior ceiling stains faster than homeowners expect. We see it every winter: a leak that started at a dormer valley or a chimney saddle, not the open roof field.
The housing stock compounds the issue. Many Mill Valley homes are mid-century builds with original skip sheathing, low-slope porch roofs, and single-layer underlayment that was never meant to last 60 years. Tamalpais Valley and Sycamore Park have their share of 1970s split-levels with plywood decking that fails near the eaves. Older Mill Valley homes along Cascade Drive and Marion Avenue often have steep-pitch sections that require tie-off points and staging, which changes how a crew approaches the work and what the homeowner should expect for schedule. We factor all of that into the estimate so the written price holds.
Our Main Mill Valley Services
Most homeowners in Mill Valley call us for one of three things: a repair that’s leaking now, a full replacement on a roof that’s reached the end of its life, or a new roof going onto an addition or remodel. Each has its own page with pricing and process detail.
Roof Repair in Mill Valley
Repairs here are rarely as simple as replacing a few shingles. The typical Mill Valley repair call involves a leak at a valley or chimney that has been working for weeks, and by the time we arrive there’s already decking damage and wet insulation in the attic. We pull back the damaged area, replace rotted decking, re-flash the penetration point, and document everything with before-and-after photos. Every repair carries our 365-Day Done Right Promise in writing, including a free second visit if it fails. Roof Repair in Mill Valley

Roof Replacement in Mill Valley
A full replacement in Mill Valley almost always means re-decking sections of the roof, upgrading from 3-tab to architectural shingles, and correcting venting that was never adequate in the first place. On canyon-facing homes we often recommend a ridge vent system paired with new intake vents, because trapped heat and moisture is what kills decking on shaded lots. We use manufacturer-backed materials from GAF, CertainTeed, and Owens Corning, and the written price includes tearing off the old roof, hauling debris, and permit coordination.

Roof Installation in Mill Valley
New roof installation in Mill Valley tends to be tied to additions, dormer rebuilds, or full remodels where the roof plane is new construction. That means working alongside a general contractor or framing crew, matching the existing roofline, and making sure the new sheathing and underlayment tie correctly into the old roof section. We spec Atlas, Tamko, or GAF systems depending on the slope and what the architect has drawn. The written price covers materials, labor, flashing, and clean-in-place roof protection.
