Roof Installation in San Anselmo
Roof installation in San Anselmo means a full tear-off down to the framing and a new system built from the deck up. On a typical 1920s Craftsman bungalow off San Anselmo Avenue, that involves stripping multiple layers of old composition, assessing the original redwood board sheathing, and replacing whatever moisture has compromised before any new underlayment goes down. Full roof installation here runs $14,800 to $32,000 depending on square footage, pitch, and what the tear-off uncovers.
What We Inspect Before Installation
We moisture-map every deck before a single bid is written. In San Anselmo’s Ross Valley microclimate, marine air stalls and holds moisture longer than in San Rafael or Fairfax, so decking routinely tests wet even when the shingles on top look intact. We don’t assume sound wood. We verify it.
New Roof Systems Built for Ross Valley Conditions
We install Class A fire-rated systems that meet Marin County’s mandatory re-roofing requirement. That matters on these older homes, where like-for-like wood shake replacement is effectively prohibited. We’ll walk you through what that means for your specific house and your material options from GAF, CertainTeed, or Owens Corning.
Roof Replacement Contractor in San Anselmo
As a roof replacement contractor working San Anselmo’s older housing stock, we treat every quote as an allowance-based contract, not a fixed number set in stone before we know what’s underneath. Homes built between 1895 and 1945 – the core of this town’s housing – commonly carry three or more tear-off layers hiding rotted redwood sheathing, failed flashing, and debris-clogged valleys. A standard suburban bid that assumes sound decking will not survive first contact with one of these roofs.
Why Our Quotes Hold Up
We write allowances into the contract for decking replacement, fascia repair, and code-triggered upgrades. That means the written price you sign reflects what we actually expect to find, not a best-case scenario. If something additional shows up once the old roof is stripped, we price it and get your written approval before doing the work. No surprise invoices.
Preserving Older Roof Geometry
Dormers, mixed pitches, and low-slope runs are common on San Anselmo’s Victorians and early Colonial Revivals. These are precisely the spots where under-flashing happens when crews treat the job like standard tract roofing. We flash every penetration and valley to the specific geometry of your roof, not a template.
Trusted Brands We Service in San Anselmo
We install and service roofing systems from seven major manufacturers, so your replacement fits the house, not just what happens to be in the truck. For San Anselmo homes, we frequently recommend architectural shingle systems from GAF and Owens Corning for their granule retention and moisture resistance in damp microclimates, and CertainTeed for homeowners who want the broadest color range on older bungalows. Because we work this area continuously, we can source regional stock quickly and keep your replacement on schedule rather than waiting on backordered materials.
Common Roof Replacement Problems We See in San Anselmo Homes
- Saturnated redwood sheathing hidden under multiple tear-off layers. Homes in the flats near San Anselmo Creek and along the lower Ross Valley routinely show decking that stayed wet long after the rain stopped. We replace it before any new system goes down, and our quotes carry an allowance for exactly that.
- Moss and lichen growth concentrated in valleys, against fascia, and behind chimneys. This microclimate traps moisture and shades the roof, so organic growth accelerates granule loss on composition shingles. Left alone, it works into the decking. We see this in the tree-covered streets off Butterfield and along Madrone.
- Rotted fascia and soffit from standing water on creek-adjacent homes. After the 2005 flood event and repeated creek overflows, homes within a few blocks of San Anselmo Creek show compromised fascia that needs replacement as a near-certainty, not an add-on surprise. We budget for it in the initial quote.
- Under-flashed dormers, valleys, and low-slope transitions on mixed-pitch roofs. Older bungalows and Victorians carry complex geometries that standard crews under-flash. The result is valley leaks and penetration leaks that show up within the first wet season. We flash to the actual roof, not a generic diagram.
Pricing for Roof Replacement in San Anselmo, CA
Here’s what San Anselmo homeowners can expect. A full tear-off and architectural shingle replacement on a standard single-story home runs $16,500 to $28,000. Larger homes, steep pitches, and creek-adjacent properties with fascia replacement needs push toward $32,000. Lower-slope or flat roof sections run $9 to $14 per square foot on average in this market. What moves the number most is not the shingle line – it’s what the tear-off reveals.

We don’t come back with change orders unless you’ve approved them in writing first. Call (945) 303-9821 for a detailed written estimate on your home.

FAQs About Roof Replacement in San Anselmo
A quote moves because the old layers hid damage, and nobody wrote a contract that accounted for it. We prevent that by moisture-mapping the deck before we bid and writing allowances into the contract for decking replacement, fascia repair, and code-triggered upgrades. If something additional appears after tear-off, we price it and get your signed approval before touching it. The price only changes if you say yes in writing. Call (945) 303-9821 and ask us to walk your specific roof before quoting.
Yes, and it does so measurably. The Ross Valley stalls marine air and holds moisture longer than San Rafael or Fairfax, which slows drying after rain and accelerates moss growth, granule loss, and soffit rot. A properly installed architectural shingle system with correct ventilation and ice and water shield in the valleys will last its rated service life here. A roof installed without accounting for that moisture load won’t. We build for it from the deck up. For an exact system recommendation, call (945) 303-9821.
Debris-clogged valleys, compromised fascia from standing water, and hidden soffit rot are the pattern after repeated flooding, including the destructive 2005 event. We budget for fascia board replacement as a near-certainty on any creek-adjacent job. On a 1920s Craftsman bungalow off San Anselmo Avenue near the creek, we stripped three layers of failed composition and found saturated redwood decking, rotted fascia, and packed debris in the valleys. We replaced the sheathing, set new ice and water shield through the valleys, and installed a Class A architectural shingle system from GAF with new soffit and drip edge – all change orders priced and approved in writing first.
We identify which upgrades a permit will trigger before work starts and write them into the contract as a line item, not a surprise. Older homes here commonly need shear nailing, ventilation improvements, or fire-rated assembly changes once the roof is opened up and inspected. We quote those as allowances and get your written approval before proceeding. No open-ended change orders. Schedule an inspection with Greg Holloway and our San Anselmo roofing team at (945) 303-9821.
Yes, if both bids carry allowances for decking, fascia, and code upgrades written into the contract line-by-line. If one bid is a flat number with no allowances and the other is higher because it accounts for what these older homes actually hide, the fair comparison is the one that won’t change. Ask each bidder what their decking allowance covers, how they handle creek-side fascia rot, and whether code upgrades are included. Ours are. We’ll put it in writing before you sign anything. Call (945) 303-9821.
