Roofing Company in San Francisco - Free Roof Inspection, Written Price

Fast, Reliable Roofing Company Across San Francisco

Most San Francisco roofs are flat or nearly flat, which means the biggest threat to your home isn’t rain or heat – it’s salt-laden fog that sits on your membrane for weeks at a time. Birchbark Roofing is a Roofing Company that specs materials for exactly this environment: hot-dip galvanized and stainless fasteners, marine-grade flashings, and membranes that hold up when fog never lets the deck fully dry. If you need a repair, replacement, or honest assessment of what your roof actually needs, call (424) 766-4937. We’ll give you a written price before any work begins, and we’ll show you a photo of the clean-up before the crew leaves.

Why Birchbark Roofing Is San Francisco’s Preferred Roofing Company

We know the difference between a Sunset District flat roof that never dries out and a Mission District roof that gets afternoon sun – and that difference changes what materials belong on the job. Our crews have repaired and replaced roofs on Victorian rowhouses, Edwardian flats, and post-war stucco homes from the Outer Richmond to Noe Valley, so we’ve seen what this city’s microclimates do to membranes, fasteners, and flashings.

Erik Lindgren leads our San Francisco team with a simple rule: protect the home first, roof second. That means shoe covers at the door, drop cloths through the hallway, and a crew that asks before moving anything on your property. Every technician is background-checked and uniformed, so you know exactly who’s walking through your door and onto your roof. We answer the phone live, 24/7 – no voicemail trees, no “we’ll call you back next business day.” If you’re reading this at 11pm worried about a leak, a real person picks up.

As part of the Cedarwell family of independent local roofing businesses since 2000, we hold every job to the Cedarwell Care Promise and our own 365-Day Done Right Promise: if the work isn’t right, we make it right.

Roof Coating in San Francisco

Roof coating in San Francisco is typically a silicone or acrylic membrane applied over an existing flat roof to extend its life and reflect heat – but in this city, the coating you choose is only as good as what’s underneath it. If the existing membrane has failing seams or rusted drip edge, coating over it just seals in the problem. We inspect first, then coat only when it makes sense.

Most roof coating jobs in San Francisco run between $4.50 and $9.00 per square foot, with a full silicone restoration on a typical 1,200-square-foot flat roof landing in the $5,400-$10,800 range. You’ll see your exact number in writing before we start.

When Coating Makes Sense

Coating buys time on a membrane that’s aging but still sound. In neighborhoods like the Inner Sunset or Bernal Heights, where roofs get partial sun, a good silicone coating can add 8-12 years of service life.

We never coat over saturated decking or failed flashings. The coating seals moisture in, and you end up with a bigger tear-off bill two years later than you’d have paid today.

Coating Materials We Trust

For San Francisco’s damp, fog-heavy zones we specify high-solids silicone coatings from GAF and Boral. Silicone tolerates ponding water better than acrylic, which matters on low-slope Victorians where water doesn’t always drain fast enough.

Free Roof Estimate in San Francisco

A free roof estimate in San Francisco should give you a written, line-item price – not a verbal number and a handshake. Ours always does. We’ll come to your home in San Francisco, inspect the roof, measure the square footage, check the decking, and give you a price in dollars before any work starts. That’s the Cedarwell Care Promise, and it’s never optional with us.

The estimate includes photos of the current condition, notes on what needs immediate attention versus what can wait, and a materials spec that names the exact membrane, fasteners, and flashings we’ll use. No allowances, no “we’ll figure it out later.”

What We Check During the Estimate

We look at seam condition, ponding areas, fastener corrosion, drip edge, and whether any rooftop decks or penetrations have compromised the membrane. We also check the party walls on rowhouses – a common source of hidden leaks in San Francisco.

If the dog needs to stay inside during the visit, no problem. We coordinate door schedules with you and keep everything controlled.

Permit and Inspection Scope

If your roof needs a permit – common when re-roofing a Victorian in San Francisco – we pull it and schedule the DBI inspection. We explain the permit cost in the written estimate so there’s no surprise line item later.

Trusted Brands We Service in San Francisco

We work with flat-roof and low-slope systems from GAF, Atlas, and Tamko, choosing the membrane that matches the exposure of your specific San Francisco block. For the Outer Sunset and Outer Richmond, where fog dominates, we lean toward GAF’s TPO and modified bitumen lines with stainless termination bars. For Mission and Castro rowhouses with existing built-up systems, we often specify Atlas and Tamko torch-down. We keep local stock of common sealants, fasteners, and drip edge in our Bay Area supply chain, so most San Francisco repairs move quickly without waiting on distant distributors.

Common Roofing Company Problems We See in San Francisco Homes

• Fastener rust on fog-exposed flat roofs. Electroplated screws and standard galvanized nails fail within a decade in the Outer Sunset and Outer Richmond, where the marine layer keeps decks damp for weeks. We specify hot-dip galvanized or stainless steel.
• Membrane penetrations from rooftop decks. In the Mission and Noe Valley, we frequently find deck framing lag-bolted straight through the roofing membrane into structural joists. Every one of those bolts is a leak path, and DBI now flags them during re-roofing permit pulls.
• Seam failure from shared party walls on rowhouses. Victorian and Edwardian rowhouses in San Francisco have adjoining walls where two roofs meet. Water gets trapped at those zero-pitch valleys and seam failures follow.
• Ponding on low-slope built-up roofs. Decades of re-roofing layers can create low spots that hold water. On tar-and-gravel systems in the Richmond, that standing water accelerates blister formation and sealant breakdown.
