Why Birchbark Roofing San Francisco Is Pacifica’s Preferred Roof Replacement Company
Pacifica homeowners call us because we treat the house like a home, not a job site. Before our crew arrives, you know exactly who’s coming: background-checked, uniformed technicians, not a rotating cast of subcontractors. We lay drop cloths through the hallway your kids use to get to the backyard. We coordinate the door schedule if your dog needs to stay inside during the tear-off. And before we leave, you get a photo of the completed clean-up, including the nail sweep around the perimeter.
Our Roof Replacement team has worked on homes from Linda Mar up through Pacifica Manor and down into Sharp Park. We’re part of the Cedarwell family of independent local roofing businesses, which has held every job to the Cedarwell Care Promise since 2000.

Erik Lindgren, who leads Birchbark Roofing, insists every job carries the 365-Day Done Right Promise: if it’s not right, we make it right. That’s stamped on every roof we touch.
Styles & brands we work with
Flat Roof Replacement in Pacifica
Flat Roof Replacement in Pacifica carries a specific set of coastal challenges that inland flat-roof work never faces. Many homes in the Sharp Park and Fairway Park neighborhoods still have their original built-up gravel roofs, and the marine layer keeps those decks damp for months at a time. The gravel traps fog moisture against the membrane, and by the time a homeowner notices a ceiling stain, the plywood underneath has often been rotting quietly for years. Our flat roof replacements start at around $12,000 for a typical Pacifica low-slope section, and the price moves up if we find significant decking damage once the old layers come off.
Tear-Off and Decking Assessment
Every flat roof job starts with a full tear-off to the deck. In Pacifica, we do not skip this step and layer a new membrane over old material, because fog-driven moisture hides underneath and ruins the new roof from below. We photograph the deck before anything new goes down, so you see exactly what we found and why we’re recommending what we’re recommending.
Marine-Grade Fastening and Flashing
Salt air in Pacifica corrodes standard galvanized fasteners within five to seven years. On flat roof replacements we specify stainless steel drip edge, hot-dip galvanized fasteners, and sealed seams at every penetration. These cost more up front, but they’re the difference between a roof that lasts twenty years and one that starts leaking around the vents in under a decade.
Roof Installation in Pacifica
Roof Installation in Pacifica means working with the wind as much as the materials. The city’s persistent onshore winds lift shingles nailed with standard patterns, and when those nails have already corroded from salt exposure, entire courses tear loose at the edges. A new roof installation here has to account for that: corrosion-resistant fasteners, proper nailing patterns for high-wind zones, and underlayment that can handle constant humidity. A full architectural shingle installation on a typical 1,200 to 1,800 square foot Pacifica home runs between $16,000 and $24,000.
Architectural Shingle Installation
Most Pacifica homes are better served by architectural shingles than standard 3-tab. The thicker profile and reinforced nail strip hold up to the wind loads coming off the ocean, and the dimensional look fits the mid-century housing stock that dominates the city. We install GAF, CertainTeed, and Owens Corning architectural lines with fastening patterns specced for coastal exposure.
Roof Decking Replacement
When we tear off an original composition shingle roof on a 1960s Pacifica home, the decking underneath is often the real story. Fog moisture and decades of small leaks leave plywood soft and spongy. We price decking replacement by the sheet and show you the damage before we cut anything, so the written price stays honest and you never get surprised by a change order.
Trusted Brands We Service in Pacifica
We work with materials from GAF, CertainTeed, Owens Corning, and IKO, and we keep the lines our Pacifica customers choose most often in steady rotation at our Bay Area supply partners. That means shorter waits on architectural shingle orders for a Sharp Park rancher, and faster turnaround on flat-roof membrane materials for a Fairway Park low-slope section. If you have a preference for a specific brand or color line, we’ll price it in writing before you commit. No guessing, no bait-and-switch on shingle quality.
Common Roof Replacement Problems We See in Pacifica Homes
- Corroded flashing and fasteners: Standard galvanized flashing around chimneys, skylights, and vents eats itself in Pacifica’s salt air within five to seven years. We see valley leaks on homes that interior inspectors never flagged, because the failure is happening outside, slowly, at the metal level.
- Hidden dry rot under built-up gravel roofs: In Sharp Park and Fairway Park, the original gravel roofs hold fog moisture against the plywood deck. The surface looks fine, but the wood underneath is spongy and failed, and nobody knows until contract workers actually pull the roof apart.
- Wind-lifted shingles on south-facing slopes: The onshore winds that blow through Pacifica hit south-facing roof planes hardest. Shingles nailed with standard patterns start lifting at the corners, then tear once the corroded nails let go.
- Ridge and soffit venting that can’t keep up: High humidity means attic air in Pacifica rowhomes and ranchers stays damp. Undersized ridge vents and blocked soffits turn that into condensation on the decking from below, which compounds the moisture already coming from above.

FAQs About Roof Replacement in Pacifica
The coastal-spec materials drive most of the difference. In San Bruno or Daly City you can often get away with standard galvanized flashing and fasteners; in Pacifica, the marine layer and salt-laden winds corrode that hardware within five to seven years, so we specify stainless steel drip edge, hot-dip galvanized fasteners, and sealed penetrations. That’s typically $1,200 to $2,500 more on a mid-sized home. You’re not paying a Pacifica premium; you’re paying for hardware that won’t fail a decade early. Call (831) 228-3330 for an exact quote.
We find hidden dry rot in the plywood decking more often than not. The gravel holds fog moisture against the roof for months at a time, and the decking rots from the top down without showing any signs on the ceiling below. When we tear off a gravel roof on a mid-century tract home, we’re prepared for decking replacement and we show you the damage before we touch it. The written price you get before the job starts includes our best estimate for what we’ll find, and we walk you through any changes with photos, not surprises.
For most Pacifica homes, architectural shingles are the right call. The onshore winds here tear at standard 3-tab shingles, especially on south-facing slopes where the wind hits hardest. Architectural shingles have a thicker profile and a reinforced nail strip that holds up to those loads far better. The cost difference on a typical rancher is usually $2,000 to $4,000, and you’re getting a roof that won’t start shedding shingles in the first big winter storm. We can price both options in writing so you can see the difference in dollars.
We stop using standard galvanized metal anywhere it can touch salt air. Around chimneys, vents, and valleys we specify stainless steel or hot-dip galvanized flashing, and every fastener is corrosion-resistant. Standard galvanized flashing in Pacifica starts failing within five to seven years, which means leaks around the exact penetrations that should be the most protected. The upgrade costs more up front, but it’s the reason our roofs don’t need a re-flash before the shingles are even halfway through their life.
Ice and water shield isn’t just for snow and ice dams; it’s the best defense against wind-driven rain and persistent fog moisture. Pacifica’s daily marine layer keeps roof surfaces damp, and onshore winds can push water under shingles and flashing in ways that gravity alone never would. On low-slope sections, we run ice and water shield at the eaves, in the valleys, and around every penetration, because that’s where fog moisture and wind-driven rain find their way in. Call (831) 228-3330 and we’ll walk your roof with you and show you where the vulnerabilities are.
