New construction roofing in San Francisco means installing a roof on a home or addition that has never had one before – a full tear-off of bare decking, fresh underlayment, and new materials built to handle the fog, wind, and wet winters that roll through the Sunset, the Richmond, Noe Valley, and every hill in between. It’s a different job from a reroof because there’s no old roof to strip; instead, the focus is on getting the decking, flashing, and ventilation right the first time, before the first nail goes into shingle or tile. Birchbark Roofing San Francisco handles new construction roofing from bare sheathing to final inspection, with a written price before any work starts and a 365-Day Done Right Promise stamped on the job. If you’re building or adding on, call (831) 228-3330 for a free estimate. For more on how this fits into a larger Roof Replacement & Installation in San Francisco project, that page covers the full scope.
What makes new construction roofing different in San Francisco is the city itself. The building department has specific requirements for roofing underlayment, nailing patterns, and fire-rated materials in certain zones, and the marine layer means moisture gets into everything if the decking isn’t protected quickly. Our team knows those local codes and the microclimates that affect them – a roof in Glen Park faces different wind and damp than one in the Marina flatlands. We plan for both.
Birchbark has been part of the Cedarwell family of independently owned and operated roofing businesses since 2000. That means every new construction roof we install follows the Cedarwell Care Promise: shoe covers at the door, drop cloths through the hallway, all debris cleared and photographed before we leave. For families with kids and pets, those aren’t extras. They’re the job.
When You Need New Construction
New construction roofing is a specific need. You’re not repairing a leak or replacing a worn-out roof – you’re building from scratch. Here are the situations where homeowners in San Francisco call us for new construction roofing:
- An addition or ADU. Whether it’s a garage conversion in the Sunset or a backyard ADU in Bernal Heights, any new living space needs a roof tied into the main structure. We install the new roof from bare framing and tie it into the existing roofline with proper flashing and crickets so water never pools at the seam.
- A full home build. If you’re building on a new lot or doing a down-to-the-studs rebuild in the Avenues, the roof is one of the last major systems to go on – and one of the most scrutinized at inspection. We coordinate with your contractor and schedule our crew when the decking is ready.
- A dormer or second-story pop-up. Adding a dormer in Noe Valley or popping the top in Potrero Hill means a new roof section that has to match the existing slope and material, or the whole roof gets redone. We handle both.
- A rotted or failed deck replacement. Sometimes the old roof comes off and the plywood underneath is too far gone to save. That’s new construction territory – new sheathing, new underlayment, new roof. In the Richmond District, where decades of fog saturate everything, we see this a lot.
- New construction on a steep San Francisco hill. Lots on Twin Peaks or Diamond Heights often have complex slopes, dormers, and multilevel roofs. New construction on those lots needs a crew comfortable with safety harnesses, steep pitches, and zero-tolerance fall protection.
If any of those sound like your project, call (831) 228-3330. Erik Lindgren and the team can walk through what the roof portion will involve, and get you a written price so you can plan the build without surprises.
Our New Construction Process
New construction roofing has its own rhythm. There’s no tear-off to work around, but there’s more coordination with your general contractor, your framing crew, and the city inspector. Here’s how Birchbark Roofing San Francisco sequences the work:
- Site walk and decking check. Before we quote anything, we walk the roof deck with you or your contractor. We check the sheathing thickness, the truss or rafter spacing, the fascia and drip edge, and the condition of any roof penetrations like skylights, vents, or chimneys. Bare decking in San Francisco rarely sits dry for long, so we look for swelling, delamination, or soft spots that need replacing before the roof goes on.
- Written price. After the walk, you get a line-item written price in dollars. Not a ballpark, not a range, not a verbal number. The exact price for the materials, labor, fasteners, underlayment, flashing, and clean-up. This is always included – it’s never a negotiation, and it never changes mid-job unless you change the scope.
- Material selection. We work with shingles and systems from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. For new construction in San Francisco, we’ll talk through what makes sense for your pitch, your exposure, and your fire zone: architectural shingles on most homes, tile or composite where the hillside dictates, and always underlayment rated for the marine layer.
- Installation with the crew you’ll meet. Our technicians are background-checked and uniformed, and you’ll know who’s on your property before the crew shows up. On a new construction site, that matters even more – contractors come and go, and you need to know the roofers are the ones you hired, not someone else. We install the underlayment, flashing, shingles or tile, ridge cap, and ventilation to manufacturer spec and San Francisco code.
- Inspection coordination. New construction in San Francisco requires city inspections at several stages, and the roof inspection happens after installation but before final sign-off. We’ll install to pass the first time and coordinate with your contractor or direct you on when to book the inspection. If the inspector flags anything, we come back under the 365-Day Done Right Promise – it’s covered.
- Clean-up photo before we leave. When the last shingle is set, we clean the site: all wrappers, nails, cut-offs, and debris picked up and hauled. Then we take photos of the finished clean-up and the completed roof and send them to you before the crew pulls away. You see the finished evidence – you don’t take our word for it.
That’s the process. If you’re mid-build and the roof portion is coming up, call (831) 228-3330 and we’ll get on the site walk calendar.
New Construction Pricing in San Francisco
New construction roofing in San Francisco typically runs between $18 and $32 per square foot depending on materials, roof complexity, and site conditions. A simple gable roof with architectural shingles on a standard lot in the Sunset or Parkside might fall at the lower end of that range; a steep multilevel roof with tile or composite in the hills above Noe Valley will run higher. Here’s a more granular look at what drives the cost:
- Asphalt architectural shingle roofing: $18 to $26 per square foot installed. This is the most common new construction roof in San Francisco – works on most pitches, handles the wet winters, and gives you 25 to 50 years depending on the product line.
- Composite or synthetic shingle: $22 to $32 per square foot installed. A good match for homes where the look of shake or slate matters but weight and fire code rule out the real thing. Boral and CertainTeed both make solid composite products.
- Tile roofing: $28 to $40 per square foot installed. Heavier, needs a stronger deck and sometimes extra structural support, and it’s the classic look in many San Francisco hillside neighborhoods. If your new construction plans call for tile, tell us early – the framing needs to be designed for it.
- Roof deck replacement (if the bare deck has weathered): $4 to $7 per square foot to replace plywood or OSB before the roof goes on. On new construction, we hope to avoid this, but fog and rain expose bare decking quickly if it’s been sitting for weeks.
- Steep pitch or multilevel complexity: Add 10% to 25% for roofs with 7/12 pitch or greater, dormers, hips, or multiple roofline transitions. Most San Francisco lots are sloped, so this is common.
- Skylights, vents, and flashings: $150 to $600 each depending on size and type. New construction usually includes bathroom and kitchen exhaust vents, plumbing stacks, and often a skylight or two.
These are honest ranges based on what we see across San Francisco new construction jobs. Your exact number comes in writing before any work starts. Call (831) 228-3330 and we’ll schedule a site walk – the estimate is free, and the written price is yours to keep.
Why Birchbark for New Construction in San Francisco
Plenty of roofing companies can install shingles. Building a new roof on a new structure in San Francisco means doing it cleanly, on schedule, and to inspection standards – and doing it without trashing the house that’s still under construction. Here’s how we prove our care in writing:
The 365-Day Done Right Promise. Every new construction roof we install is covered for a full year. If the work isn’t right – a flashing that leaks, a shingle that lifts, a vent that isn’t sealed – we make it right. That’s stamped on every job, including new construction. No fine print, no amortization schedule, no argument.
The Cedarwell Care Promise. Birchbark has been part of the Cedarwell family of roofing companies since 2000. Independent, local, and held to a standard that means clean-up like it’s our own home, asking before we move or touch anything, respecting your family’s time and quiet hours, and explaining the price before the work. On a new construction site full of contractors, that level of care is rare – and it’s the standard on every Birchbark roof.
Shoe covers, drop cloths, and a clean-up photo. On every visit, our technicians wear shoe covers at the door and lay drop cloths through the hallway. When the roof is done, we photograph the clean-up and send it to you before the crew leaves. If the dog needs to stay inside, we coordinate the door schedule with you – and where there’s a product choice, we use pet-safe options.
A live person answers the phone 24/7. Build schedules change at 6 a.m. or 8 p.m. If you need to reach us about a roof going on next week, you’ll talk to a person, not a voicemail tree. Call (831) 228-3330 any time – nights, weekends, holidays included.
Written price, always. Every new construction estimate ends with a written line-item price in dollars. Not a verbal range, not a handshake, not a “we’ll figure it out as we go.” The number you approve is the number you pay. If the scope changes, the price change gets written down before the change is made.
Erik Lindgren leads Birchbark Roofing San Francisco, and every new construction roof that goes out under that name gets built to the same standard: the decking is protected, the flashing is right, the roof is inspected, and the site is clean when we pull away. If you’re building in San Francisco and the roof is coming up, call (831) 228-3330 for a free estimate and a written price.
FAQs – New Construction
How much does new construction roofing cost in San Francisco?
New construction roofing in San Francisco typically costs between $18 and $32 per square foot installed, with architectural shingles at the lower end of that range and tile or composite at the higher end. Your exact price depends on the roof’s pitch, size, material, and the condition of the decking. Birchbark gives every client a written line-item price before any work begins, and estimates are free. Call (831) 228-3330 to get your number in writing.
Can you install a roof on my San Francisco new build or addition?
Yes. Birchbark Roofing San Francisco installs new construction roofs on full home builds, ADUs, additions, dormers, and second-story pop-ups throughout the city. We work with your contractor’s schedule and install from bare decking through final inspection, using materials from GAF, CertainTeed, Owens Corning, IKO, Atlas, Tamko, and Boral. If your build is mid-framing, call (831) 228-3330 to schedule a site walk before the decking goes on so we can flag any prep work ahead of time.
Is it cheaper to do new construction roofing or wait and reroof later?
New construction roofing is almost always cheaper than reroofing the same structure later. There’s no tear-off cost, no disposal fee for old shingles, no hidden decking repairs discovered after the fact, and no double labor for stripping and reinstalling. Doing the roof right during the build also protects the framing and interior finishes from San Francisco’s fog and rain. If you’re weighing the timing, call (831) 228-3330 and we’ll walk through the math with you.
What does the Cedarwell Care Promise mean for my new construction project?
The Cedarwell Care Promise means clean-up like it’s our own home, asking before we move or touch anything, respecting your family’s time and quiet hours, and explaining the price before the work. On a new construction site, that translates to shoe covers and drop cloths on every visit, pet-safe product choices where available, debris cleared and photographed before we leave, and a written price in dollars before any work starts. Birchbark has been part of the Cedarwell family of roofing companies since 2000, and every job – including new construction – is covered by the 365-Day Done Right Promise.
