Roof City did an excellent job on my roof. They were professional, fast, efficient, and clean. They over- delivered on their promise to do a five- star job in two days, which included all materials and permits needed. They deserve a 10 star rating 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

From the very first consultation, we knew we'd made the right choice. The team was knowledgeable and genuinely listened to our concerns about energy efficiency and design. We've already noticed a drop in our energy bills.

Hamilton Exteriors repaired extensive dry rot damage on our home's exterior. Their attention to detail and commitment to quality were evident throughout the project. Our home looks better than ever.

Local Expertise

Exterior Projects in San Rafael, California

San Rafael is Marin County's largest city with approximately 23,000 housing units. The mix of mid-century homes in the Dominican and Gerstle Park neighborhoods alongside newer developments means a wide range of roofing needs.

Marin County and the City of San Rafael both require building permits for roof replacements. San Rafael's Community Development Department typically processes residential permits within 1-2 weeks.

Local Tip

San Rafael's Terra Linda neighborhood was one of the first master-planned communities in Marin — most homes there were built in the 1950s-1960s and are on their second or third roof. Original low-slope designs benefit from TPO or modified bitumen instead of standard shingles.

Serving San Rafael's Best Neighborhoods

Hamilton Exteriors has completed projects across San Rafael — from Dominican to Canal District. Here are some of the communities we serve.

Sun Valley

From energy-efficient window installations to ground-up custom homes, Sun Valley residents choose Hamilton Exteriors for our design-build expertise. With San Rafael's microclimate — Summer highs upper-70s°F — material selection matters. We handle architecture, engineering, permits, and construction.

Local Considerations

Fog, mildew and the case for fiber cement in San Rafael

Marin's persistent marine layer means San Rafael homes — especially shaded properties in Dominican, Sun Valley and the western canyons — stay damp far longer than inland Bay Area cities. Wood and engineered-wood siding mildew, swell and rot in this climate, and field-painted stucco chalks within a few seasons. We specify James Hardie HardiePlank or HardieShingle ColorPlus fiber cement as the default re-side and pair re-roofs with zinc or copper ridge strips that inhibit moss and algae growth, which alone adds 5-10 years to roof life on shaded lots.

Neighborhoods we serve in San Rafael

Dominican

Wooded hillside lots near Dominican University with mature oaks shading roofs and accelerating moss and algae buildup.

Gerstle Park

Early-1900s craftsman and Victorian homes with original wood siding and complex multi-pitch roofs that need a careful, code-compliant retrofit.

Terra Linda

Eichler and 1950s low-slope ranches where standard shingles are the wrong material — TPO, modified bitumen or standing-seam metal is the durable answer.

City of San Rafael Community Development Department

Residential re-roof and re-side permits typically issued in 1-2 weeks; properties in the Wildland-Urban Interface overlay (much of west and north San Rafael) require Class A assemblies and ember-resistant venting per Marin County code.

Frequently Asked Questions

Didn't find the answer to your question? Call Now (650) 977-3351

What areas do you serve?

We serve Northern California across three regions: the San Francisco Bay Area, Greater Sacramento, and the Central Valley. Our published guides cover 14 counties and 88 cities. Our Castro Valley and Sacramento offices support local estimating, permit coordination, and project planning across these regions.

How does billing and financing work?

Financing may be available for eligible projects with approved credit. Available terms depend on lender approval, project scope, and current programs. Your project manager can review the options that apply before work begins. We also accept checks, ACH, and major credit cards.

Are you licensed and insured?

Yes. Hamilton Exteriors holds CSLB License #1078806, active general liability coverage, and the required contractor bond. We also hold GAF Master Elite and James Hardie Elite Preferred credentials. We can provide current proof of coverage before work begins.

Do I need a permit for my exterior project?

Permit requirements depend on the project scope and local jurisdiction. Hamilton Exteriors coordinates required applications, plan documents, corrections, and inspections. Permit fees and allowances appear in the proposal before construction begins.

Do I need a permit for a roof replacement in San Rafael?

Yes. The City of San Rafael Community Development Department requires a building permit for every re-roof, and homes within the Wildland-Urban Interface overlay (much of west and north San Rafael) must use Class A fire-rated assemblies and ember-resistant vents under Marin County code. Standard residential permits are usually issued in 1-2 weeks. We pull and close the permit in your name and handle Marin's WUI documentation as part of the project.

How much does a general contractor cost in San Rafael?

General contractor rates in San Rafael typically range from $150 to $250 per hour for labor, or 15 to 25 percent of total project cost for project management. At Hamilton Exteriors, we provide fully itemized estimates that break out materials, labor, permits, and overhead separately. For a typical roof replacement on a 2,000 sq ft home in San Rafael, expect to pay $20,500 to $26,000 for asphalt shingles, including all permits and cleanup. See our roof replacement cost guide for detailed pricing.

Do I need a permit for a roof replacement in San Rafael?

Yes. The City of San Rafael requires a building permit for any roof replacement. Permit fees range from $500 to $800 for a standard asphalt shingle roof (Hamilton Exteriors 2024-2026 project data). Your contractor should handle the permit application and all inspections. If a contractor suggests skipping the permit, find a different contractor. Hamilton Exteriors pulls all permits on every project.

What roofing material is best for San Rafael's climate?

For most San Rafael homes, premium architectural asphalt shingles from GAF, CertainTeed, or Owens Corning offer the best balance of cost, durability, and fire resistance. Metal roofing is an excellent choice for homes in fire-prone hillside areas, as it carries a Class A fire rating and lasts 40 to 70 years. Tile roofing works well on Spanish-style homes but adds significant structural weight.

How long does a home addition take in San Rafael?

A typical first-floor addition of 200 to 400 sq ft takes 4 to 6 months from permit approval to completion. This includes design, engineering, permitting, and construction. Second-story additions take 6 to 9 months due to the complexity of structural work and the need to protect the existing home during construction. Permit approval in San Rafael typically takes 4 to 8 weeks.
