Wellborn Roofing: The San Francisco Owner’s Guide
We stock and install Wellborn-compatible roofing components across San Francisco, with most roof repairs running $470 to $2,125 installed and full roof replacements ranging from $9,440 to $23,600 depending on square footage, pitch, and the existing substrate condition. You’ll usually discover a failed Wellborn roof component the same way every homeowner does: a water stain on the ceiling after a heavy fog cycle rolls through the Richmond or Sunset, or shingle granules collecting in the gutters after a winter storm. The good news is this rarely means a full tear-off. More often it’s a targeted repair, and we can usually get a written price to you the same day you call.
One thing to be clear about up front: Bradford Remodeling Co San Francisco is an independent service provider. We are not affiliated with Wellborn corporate and we don’t claim to be. What we do is install and repair roofing systems, including Wellborn-spec materials, with a documented scope and a written guarantee. If you’ve been burned by a roofer who priced the job over the phone and changed the number at the door, that’s exactly the problem our process eliminates.
Which Wellborn Models This Applies To
Wellborn’s roofing line shows up most often in San Francisco as architectural asphalt shingle systems and standing-seam metal panels, typically sold through regional supply houses and installed on homes built or re-roofed between the mid-1990s and today. The compatibility gotcha most homeowners miss: Wellborn produced different profile depths across their metal panel series, and a 1.5-inch rib panel will not interlock correctly with a 1-inch rib from an earlier run. We measure the panel profile and fastener spacing on site before quoting, because guessing gets you a roof that leaks at the lap joints.
For shingle work, Wellborn architectural shingles use the same nail strip and exposure dimensions as most high-end laminated shingles on the market, which means quality aftermarket equivalents from GAF or Owens Corning will lay correctly and hold a manufacturer warranty. We stock both OEM-surface materials and documented aftermarket matches. If you have the original Wellborn packaging or the shingle wrapper tucked in the garage, that makes identification quick. If you don’t, we pull a shingle and match the grain pattern and color against current production stock. Curtis Lane has been doing this long enough to spot a faded Timberline blend from across a driveway, and he’s the one writing your scope.
Styles & brands we work with
Signs Your Wellborn Roofing Is Failing
- Granules in the gutters or at the downspout elbows. Asphalt shingles shed granules as the fiberglass mat ages and the UV-stabilized surface breaks down. In San Francisco, the fog-sun-fog cycle accelerates this more than most owners realize. If you see a consistent trickle of granules every time it rains, the shingles are past mid-life and water absorption is climbing.
- Water staining on ceilings below the roofline, usually on the west-facing rooms first. This is the classic fog-driven moisture creep Curtis sees in Outer Sunset and Richmond District homes. Moisture-laden air pushes through worn underlayment and condenses inside the roof assembly. The stain often shows up weeks after the wet cycle, which confuses people.
- Lifted or curled shingle tabs at the eaves. Wind gets under the tab edge, and once one lifts, the nail seal below it fails. On a multi-story San Francisco home with full wind exposure, a few lifted tabs at the rake will become a peeled section within a season.
- Rust blooms or white oxidation on metal roof panels and fasteners. Salt-laden fog near the Pacific is hard on coated steel, especially the exposed fastener washers on older Wellborn metal systems. Once the washer rubber dries out and the steel corrodes, you get a pinhole leak at the fastener line.
- Daylight visible through the roof sheathing from inside the attic. That means the underlayment has failed and the shingles are merely decorative. This is the point where patching no longer holds, and we tell you straight: it’s time to price the replacement, not another repair.

AfterReplacement Cost & What’s Included
In San Francisco, a targeted Wellborn roof repair runs $470 to $2,125 installed. That covers the material, labor, and disposal of the old material, but it assumes the roof deck and underlayment are still sound. A full roof replacement lands between $9,440 and $23,600, driven by square footage, the number of roof planes, the pitch, and what lies beneath the shingles. Steep roofs on three-story Victorians cost more because every bundle goes up a ladder by hand, and the flashing work around chimneys and party walls takes real time to do correctly.
Every quote we write is a fixed number, on paper, before any work starts. You’ll see the material line item, the labor line item, and the disposal fee separated. No change orders appear at the door because there’s nothing to change: the scope was measured on the roof, not over the phone. And once the job is done, the 365-Day Done Right Promise kicks in. If the repair or replacement fails within the full year, we return and correct it at no charge. That’s The Garrison Standard, and it’s in writing every single time.
DIY or Call Us?
Roofing is one of the trades where a homeowner can safely assess the problem themselves. You can walk the perimeter with binoculars, check the gutters for granules, and inspect the attic for daylight. What you should not do is get on a rope and harness and start replacing shingles on a San Francisco roof that’s two or three stories up with a 6/12 pitch or steeper. The falls are the obvious risk. The less obvious one is walking a rotted deck without knowing it and going through into an attic. HardiePlank doesn’t matter, architectural shingles don’t matter, no shingle is worth a broken back.
We have background-checked, uniformed techs who do this work daily, and we carry full fall protection and insurance. If you’ve already committed to doing the inspection yourself, we respect that. But if you find lifted tabs, granule loss, or daylight, call (831) 610-5598 and let Curtis Lane walk the roof and give you a straight number on paper. Estimates are free.
FAQs
Architectural asphalt shingles in San Francisco’s coastal fog zones typically last 18 to 22 years, while Wellborn metal roofing systems usually run 30 to 40 years before the first fastener failures appear. The microclimate matters more than the brand: a home three blocks from Ocean Beach gets more salt and fog stress than a house in Noe Valley, and the difference shows up as accelerated granule loss and flashing corrosion. Call (831) 610-5598 and we’ll check your roof’s actual condition rather than guess from a chart.
Yes, if the failure is localized, such as a small section of missing shingles, failed flashing, or a few corroded fasteners on a metal panel, a repair usually makes sense and runs $470 to $2,125. The honest answer Curtis gives every roof: once the underlayment has failed and you’re seeing water stains in multiple rooms, every repair is just rent until the replacement catches up with you. We’ll tell you which situation you’re in and put the number in writing either way.
A targeted repair is done in a single visit, usually two to four hours including the ladder setup and site cleanup. A full roof replacement on a typical San Francisco single-family home runs two to four working days, depending on the pitch and how much of the old deck needs replacing. We schedule the work and keep the site clean at the end of every day, because a roof job that leaves nails in the driveway is not squared away.
We keep common architectural shingle colors and underlayment on the truck, and we source Wellborn-spec metal panels, ridge caps, and flashing through our documented supplier network, typically available for pickup the same week. For rare colors or discontinued profile depths, we’ll tell you before you spend anything and give you an honestly matched aftermarket option. We also stock compatible parts for KraftMaid, Cambria, and Silestone when an interior component gave out at the same time.
