Fast, Reliable Roof Installation Across San Rafael
San Rafael’s hills throw real challenges at a roof. Morning fog rolls off the bay, soaks the eastern slopes, then burns off by noon and leaves shingles baking in dry heat. That swing, sometimes 30 degrees in a day, is hard on materials. We’ve installed roofs on homes along Las Gallinas Avenue where the afternoon sun hits like a hammer, and in the shaded pockets near Dominican University of California where moss wants to colonize every north-facing slope. We know which underlayment handles both conditions, and we specify it before we ever pull a permit.
A new roof installation in San Rafael typically runs $12,500 – $28,000 for single-family homes, with most asphalt shingle jobs landing between $15,000 and $22,000. TPO flat roofs on the contemporary homes near the canal start around $9,500. We pull permits through the City of San Rafael Community Development Department, coordinate inspections around their schedule, and never start work without a written price you’ll see on your phone.
Our Roof Installation crews work out of our San Francisco Bay Area office and serve San Rafael directly. You’ll get a live trackable arrival time, before-and-after photos sent by text, and a digital invoice when we’re done. Call (325) 246-5075 to schedule your free estimate.

Every installation carries our 365-Day Done Right Promise. If something we installed needs attention within that first year, we fix it. No charge, no negotiation, no runaround.
Roof Flashing Installation in San Rafael
Roof Flashing Installation in San Rafael addresses the metal strips that seal joints around chimneys, vents, skylights, and wall intersections. On the older homes in the Gerstle Park neighborhood, original flashing was often galvanized steel that corrodes after decades of salt-laden bay air. New installations use copper, painted steel, or aluminum, depending on the roof material and your budget. A typical flashing installation or replacement in San Rafael runs $450 – $1,200 per penetration or wall section.
Chimney and Vent Sealing
Chimneys on San Rafael’s pre-war bungalows often sit proud of the roofline with multiple planes meeting at odd angles. We fabricate custom step flashing and counterflashing to fit each intersection, then seal with manufacturer-approved sealants rated for the temperature swings these roofs endure.
Wall and Dormer Junctions
The split-levels and additions in Terra Linda frequently have walls that dead-end into shingle slopes. These headwall flashings take the most water in a driving storm. We install continuous kickout diverters to send water into gutters, not behind siding.
TPO Roofing Installation in San Rafael
TPO Roofing Installation in San Rafael serves the flat and low-slope roofs common on modern builds near the canal, commercial conversions in the downtown corridor, and the mid-century ranchers in Santa Venetia with their nearly level garage roofs. TPO, short for thermoplastic polyolefin, is a single-ply white membrane that reflects heat rather than absorbing it. For San Rafael homeowners fighting summer attic temperatures, that reflective surface can drop cooling loads noticeably. A typical TPO installation in San Rafael runs $9,500 – $18,000 depending on square footage, insulation requirements, and mechanical unit tie-ins.
Mechanical Attachment Methods
We mechanically fasten or fully adhere TPO based on wind exposure. Homes on the exposed ridges near China Camp State Park get fully adhered systems with seam plates. Sheltered inland installations may use mechanically attached membranes with faster installation times.
Insulation and R-Value Upgrades
Many San Rafael flat roofs were originally built with minimal insulation. During TPO installation, we can add tapered polyiso insulation to correct ponding and bring the assembly up to current Title 24 energy standards.
Trusted Brands We Service in San Rafael
We install GAF Timberline HDZ and Atlas StormMaster Slate on the steep-slope homes throughout Marinwood and Montecito. For homeowners who want the clay tile look without the structural load, Boral’s lightweight concrete tiles work well on the 1970s-era homes in Terra Linda that weren’t framed for traditional Spanish tile. Tamko’s Heritage series offers solid performance at a mid-range price point we specify often for rental properties and flips near the freeway corridor. We stock common accessory pieces locally, so a damaged ridge vent cap or a bundle of matching shingles doesn’t turn into a two-week wait. Every brand we carry backs its materials with a manufacturer’s warranty, and we register that warranty in your name so there’s no paperwork chase if you ever need it.
Common Roof Installation Problems We See in San Rafael Homes
- Fog-cycle moisture damage. The daily fog-to-sun pattern in San Rafael traps moisture under improperly vented roof decks. We specify ridge vents and soffit intake systems that move air even on still mornings, preventing the plywood delamination we see in homes near the bay.
- Earthquake-legacy framing irregularities. Post-1989 retrofits in the Gerstle Park and downtown areas sometimes left rafter ties in odd configurations. Our crews measure every plane independently rather than assuming symmetry, so the shingle layout works with the actual structure.
- Original wood shake roofs past service life. Many Santa Venetia and Montecito homes still have cedar shakes installed in the 1970s. These are tinder-dry and often conceal rotted skip sheathing. We strip to the rafters, replace damaged decking, and install fire-rated Class A assemblies that satisfy current Marin County wildfire preparedness guidelines.
- Flat roof ponding from settled drains. The low-slope additions on 1960s ranchers frequently have original scuppers or drains that no longer sit at the low point. During TPO installation, we re-establish proper drainage with tapered crickets and sometimes relocate drains to where water actually collects.
Pricing for Roof Installation in San Rafael, CA
Most complete asphalt shingle roof installations in San Rafael fall between $15,000 and $22,000 for a typical 2,000-square-foot home. Smaller homes or simple gable roofs with single-layer tear-off sometimes land closer to $12,500. Complex roofs with multiple valleys, steep pitches, or hardscape that requires extensive protection can push toward $28,000. TPO membrane systems for flat roofs generally start at $9,500 and range to $18,000 depending on insulation and mechanical tie-ins.
What moves the number: roof square footage, number of layers to remove, decking replacement (we charge per sheet if we find rot, with your approval), pitch steepness, accessibility for material delivery, and the shingle line you select. We give you a written line-item quote before work starts. The price on that quote is the price on your invoice. No change orders unless you add scope. Call (325) 246-5075 for your free estimate.

FAQs About Roof Installation in San Rafael
Most San Rafael installations are scheduled within 2 – 3 weeks of estimate approval, weather permitting. We pull permits through the City of San Rafael, which typically takes 5 – 7 business days for residential re-roofs. Call (325) 246-5075 to check current availability and get your free estimate.
Yes. We work from the bay-facing slopes of Loch Lomond and the canal district up through Terra Linda, Montecito, Santa Venetia, and the hillside homes near China Camp. Each area has distinct exposure and code considerations, and we specify materials accordingly.
We do not offer same-day full roof installations, which are planned construction projects requiring permits and material orders. For emergency protection after storm damage or sudden failure, we offer temporary tarping and then schedule permanent installation. A live person answers calls 24/7 to coordinate emergency response.
San Rafael pricing runs roughly comparable to Corte Madera and San Anselmo, slightly higher than Novato due to permit fees and bay-area labor rates. The specific range for your home depends on roof size and complexity, not zip code. Call (325) 246-5075 for an exact quote.
Every installation includes our 365-Day Done Right Promise in writing. Manufacturer material warranties range from 25 years to lifetime depending on the shingle line you choose. We register these warranties in your name and provide documentation by text and email.
