Fast, Reliable Roof Replacement Across San Francisco
Every roof replacement in San Francisco happens on a tight lot with a neighbor close enough to touch. That single fact shapes the schedule, the permitting, and how the estimate gets built. We’re a roofing specialist that runs inspection, repair, and replacement under one contractor, and we know what a narrow Victorian row house demands before a single shingle comes off. Whether you’re east of Twin Peaks or out toward the fog belt, a straight answer starts with a call to (855) 473-8840. We answer 24/7. Fast dispatch from 7am to 7pm, Sunday through Friday.

Why San Francisco Homeowners Call Sunstone Roof Repair for Roof Replacement
Most homeowners who call us have already been told they need a full replacement, and they want a second opinion before they commit. We treat an inspection as a service, not a sales pitch. Our technicians have up to 12 years of experience and can tell you whether your roof needs a replacement, a targeted repair, or simply a professional eye on it this year. That honest diagnosis is the whole point of how we work.
San Francisco roofs are their own animal. Row houses share party walls, and re-roofing one home means negotiating firewall continuity with the building next door, sometimes accessing through an adjacent property, and keeping the job inside Department of Building Inspection and fire department expectations. We’ve built our process around that reality, so the work stays watertight at the shared wall and the neighbors aren’t surprised.
We install and service materials from seven recognized manufacturers, which means real choice instead of a single-brand pitch. If a match to an existing roof matters, or you want the best-value product for a steep gable buried in fog, we can match the system to the house. Estimates are free and written line by line.

New Roof Installation in San Francisco
New Roof Installation in San Francisco is a different job than it is almost anywhere else in the Bay Area. On the steep gable roofs common to 1880s to 1930s Victorian and Edwardian row houses, the assembly is often layered: original redwood or cedar shingles under an old tar-and-gravel overbuild, or a small penthouse addition that leaves the roof full of transitions. When a homeowner needs a full rebuild, it usually means the decking is suspect, flashing around chimneys and skylights has failed, or the existing layers are too far gone to repair. A typical full replacement on a San Francisco row house runs $18,000 – $45,000, with layered assemblies and complex penetrations pushing toward the upper end. The written estimate sets the final price.
What a Full Replacement Covers
A full tear-off means stripping down to the decking, replacing rotted sheathing, installing underlayment and ice and water shield in the valleys, and rebuilding flashing at every chimney and penetration. Drip edge goes along each exposed rake, and a new ridge vent tops it off. On a shared-wall lot, we re-establish firewall continuity before the new shingles go down.
Rebuilding the Assembly Right
Layered overbuilds hide the problems until tear-off, so we plan the decking replacement into the scope from the start. Architectural shingles from GAF or CertainTeed are a common choice for these steep roofs, and we match the system to how much damp the house actually sees.
Reroofing in San Francisco
Reroofing in San Francisco often starts as a repair and turns into something bigger once the decking is exposed. Because the west-side fog keeps shingles perpetually damp, technicians routinely find rot beneath the top course and moss growing between courses rather than obvious surface wear. That means a roof that looks fine from the street can be hiding decay underneath. A re-roof on a typical row house runs $12,000 – $30,000 depending on how much decking needs replacing and how complex the flashing details are. A written estimate locks in the number before work begins.
Why Scope Grows After Tear-Off
Flat tar-and-gravel or shingle-over-shingle layering hides moss and rotted sheathing until the top layers come off. We go into every re-roof prepared for decking surprises rather than discovering them mid-job and handing you a change order. Whatever the decking reveals, the price is fixed by the estimate.
Staging on a Narrow Lot
With no driveway and no staging space, materials get staged on the street under posted parking control, and adjacent roofs get protected. Sequencing tear-off and material handling well is what keeps a tight-lot job moving without straining relations with the neighbors.

Trusted Brands We Service in San Francisco
We work with roofing materials from GAF, CertainTeed, Tamko, and Boral, spanning value, mid-range, and premium lines. That range means we can match replacement sections to an existing roof or recommend the product that fits your climate and budget, rather than the one brand we happen to favor. We don’t stock parts locally or claim to, but our familiarity across multiple manufacturer systems lets us integrate with virtually any residential roof we encounter in San Francisco. When you’re ready for a straight diagnosis and a written quote, call us.

AfterCommon Roof Replacement Problems We See in San Francisco Homes
- Layered overbuilds. Flat tar-and-gravel or shingle-over-shingle assemblies hide rotted decking and moss between courses until tear-off, so the true scope only settles once the roof is opened up.
- Party-wall and firewall gaps. When flashing and fire-stopping at the shared wall aren’t rebuilt to DBI and fire department expectations, an inspection fails and the job gets reworked at your expense.
- Damp-driven decay in the fog belt. In the Sunset and Richmond districts, original cedar shingles rot from the underside and moss works in between courses, so surface wear tells only half the story.
- Unplanned tight-lot access. No staging space and no neighbor access means material handling and tear-off sequencing go sideways, stretching the schedule and souring relations with adjacent owners.
Pricing for Roof Replacement in San Francisco, CA
Roof replacement in San Francisco typically runs $18,000 – $45,000 for a full rebuild and $12,000 – $30,000 for a re-roof where much of the structure stays intact. What moves the number: how many layers need stripping, how much decking is rotted underneath, how complex the chimney and skylight flashing is, and how much neighbor access the tight lot requires. A shared-wall row house with a layered assembly sits at the top of the range; a simpler steep-gable roof at the lower end. We give a free written, line-item estimate so you see exactly what’s covered and what isn’t. That written estimate sets the price, and it doesn’t move once work starts.

FAQs About Roof Replacement in San Francisco
Yes, in many cases you do – it’s a step that has no equivalent in the suburban Bay Area, where each roof stands free. Because row houses share party walls, a replacement often needs written neighbor notice and temporary access across an adjacent building’s roof or lightwell. We help you plan that access and rebuild firewall continuity at the shared wall. Call (855) 473-8840 for a free estimate that accounts for it.
Fog makes a reroof-over risky because damp shingles and hidden decay beneath the top course won’t show until the layers come off. The prevailing west-side fog keeps roofs perpetually damp, so moss and rot often sit under what looks like a sound roof. That’s why we inspect for decay beneath the surface before recommending any overbuild. Call (855) 473-8840 to book a free estimate.
Historic and overlay districts can require review before façade-visible work proceeds, and shared-wall fire-stopping has to meet DBI and fire department expectations. We plan the permit path with your city’s building department so the work doesn’t stall mid-job. Call (855) 473-8840 and we’ll walk you through what your property type triggers, with estimates free.
Noise ordinances limit when tear-off and hammering can happen, so we build the schedule around them rather than fight them. On a tight lot with neighbors inches away, that means sequencing the loudest work within allowed hours and keeping the site clean. Call (855) 473-8840 for a free estimate that reflects a realistic schedule.
Compare line by line for decking replacement, flashing at chimneys and skylights, party-wall fire-stopping, and neighbor access – those four items drive most of the cost on a row house. A bid that skips them is where the surprise change orders come from. Call (855) 473-8840 for a free written, line-item estimate you can compare fairly.
