Roof Replacement in Mill Valley - Free Roof Inspection, Written Price

Fast, Reliable Roof Replacement Across Mill Valley

Roof replacement in Mill Valley costs between $18,000 and $42,000 for most homes, with asphalt shingle replacements averaging $22,000 to $31,000 depending on roof complexity, access, and whether your existing roof is non-compliant wood shake that needs full tear-off. Because Mill Valley sits inside a Very High Fire Hazard Severity Zone, your replacement must use a Class A fire-rated assembly, and on tight hillside lots, staging and access materially change the quote.

We work throughout Mill Valley, from downtown flats near Sycamore Park up to the steep rooflines above Cascade Drive and the shaded canopy streets of Homestead Valley. Our crews know how a roof on a tight Homestead Valley lot differs from one on an open Larkspur hillside, and we plan every replacement around that reality. You’ll get a written price before any work starts, a live person on the phone whenever you call, and a full year of accountability after the job.

Why Tilehurst Roofing Is Mill Valley’s Preferred Roof Replacement Company

Tilehurst Roofing is a Kingswell family company, founded in 2000, and every Mill Valley replacement we run follows the same operating rules: say the price before the work, show up in the window we gave, leave the site cleaner than we found it, put the guarantee in writing, and come back if anything fails. We don’t make you chase a project manager. We don’t change the number when the dumpster arrives. We put the price in your hands before a single shingle is ordered.

What Mill Valley homeowners tell us after the job matches what we hear across the Bay Area: they’d been burned before by a no-show or a door-price change, and they called us because a neighbor in Tamalpais or Homestead Valley recommended Tilehurst. Greg Holloway leads our team, and every technician who steps on your Mill Valley roof is background-checked and uniformed. You’ll know exactly who’s on your property because we’ll introduce them by name before they open the ladder.

Asphalt Shingle Roof Replacement in Mill Valley

Asphalt Shingle Roof Replacement in Mill Valley means tearing off the existing roof down to the decking, replacing any rotted or delaminated plywood, installing new underlayment and flashing, and then laying a full field of shingles that meet the VHFHSZ Class A fire requirement while standing up to the damp, shaded conditions most Mill Valley rooftops live in. Most asphalt shingle replacements in Mill Valley run $22,000 to $31,000, with the exact number driven by square footage, tear-off layers, decking repair, and how tight the access is.

Architectural Shingles for Cascade and Tamalpais Shade

In the Cascade, Tamalpais, and Homestead Valley neighborhoods, dense redwood canopy keeps roofs wet for months at a time. We spec algae-resistant architectural shingles from CertainTeed, GAF, or Owens Corning as the default here, because standard composition in full shade shows moss and lichen growth within three to five years. Architectural shingles also give you a thicker, more dimensional profile that handles the moisture load better than three-tab.

Roof Decking Replacement Under Old Shakes

A large share of Mill Valley homes built between the 1940s and 1980s still carry original wood shake or shingle roofs. When we tear those off, we almost always find decking that has to be replaced, sometimes in full sheets, sometimes in patches where years of trapped moisture rotted the plywood. We price decking replacement into your written quote, not as a surprise change order, so you know the full number before we start.

New Roof Installation in Mill Valley

New Roof Installation in Mill Valley is a different job than a re-roof, because everything from the underlayment up goes in fresh on new or stripped decking, and you have full control over material choice, ventilation, and flashing design from day one. New roof installation in Mill Valley typically runs $26,000 to $42,000 for a full replacement on a new or fully stripped home, depending on roof size, pitch, and whether the site is a tight hillside lot or a flat in-town parcel.

Steep Hillside Rooflines and Complex Flashing

Custom homes from the 1970s through 1990s on the Mt. Tamalpais foothills often have steep pitches and complicated rooflines with multiple valleys, dormers, and low-slope transitions. On these homes, a new roof installation is a flashing and underlayment job first and a shingle job second. We spec ice and water shield in the valleys and wider metal flashing at transitions, because Mill Valley’s rainfall and needle debris will find any gap a standard flashing leaves open.

Full Tear-Off and New Sheathing on Remodels

When a Mill Valley homeowner is re-roofing as part of a remodel or addition, we coordinate the tear-off and new sheathing with your builder’s schedule. The written price you get from us covers the roof scope on its own, so you can see exactly what the roofing line item costs, even when it’s bundled into a larger project.

Trusted Brands We Service in Mill Valley

We install and service roofs from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral, so you get the product that fits your Mill Valley home, not whatever happens to be in the truck that week. For the shaded canopy neighborhoods around Cascade and Homestead, we lean on CertainTeed’s algae-resistant architectural line and Tamko’s fire-rated composition options. For homes where you want a longer manufacturer-backed fire rating, GAF’s Class A architectural shingles are a common choice. Parts and materials are sourced locally and staged ahead of your start date, so you’re not waiting on a supply house in Novato while your roof is open.

Common Roof Replacement Problems We See in Mill Valley Homes

• Wood shakes failing VHFHSZ fire review. Mill Valley’s entire footprint is a Very High Fire Hazard Severity Zone, so original wood shake or shingle roofs are now non-compliant. A replacement using standard composition that isn’t a listed Class A assembly can fail inspection, forcing a tear-off of brand-new shingles just to pass fire review. We never spec a roof in Mill Valley that won’t pass the fire review the first time.
• Redwood needle mats in valleys and low-slope transitions. In Cascade and Tamalpais, redwood needles accumulate into a moisture-retaining mat that holds water against the underlayment all winter. If the re-roof skips wider valley flashing and algae-resistant shingles, you’ll see heavy moss and lichen within three to five years. We detail valleys for Mill Valley’s canopy, not for a dry suburban lot.
• Tight lot staging and shared driveways. Mill Valley lots are small, and dumpsters and material stacks often end up in shared driveways or permitted curb lanes. Without a staging plan and neighbor notice, you can get a stop-work order mid-job. We handle the staging permit and walk the party-wall neighbor through the plan before the first square comes off.
• Persistent damp from the Mt. Tamalpais rain shadow. Parts of Mill Valley receive 45 to 60 inches of rain annually, two to three times San Francisco’s total, and the redwood canopy means roofs never fully dry between storms. That accelerates flashing corrosion and decking rot. We inspect the existing flashing and decking during the estimate, so you know upfront what needs replacing.
