Tamko Roofing: The San Francisco Owner’s Guide
If you’ve got a Tamko roof that’s leaking, lifting, or showing granule loss, here’s the straight answer: Bradford Remodeling Co San Francisco installs and repairs Tamko-compatible roofing systems, and roof repair in San Francisco typically runs $470 to $2,125 depending on the damage. We stock Tamko shingle-compatible materials on our trucks. Most roof leaks we see in San Francisco start small, in one of three places: flashing, a ridge cap, or a single compromised shingle course, and they get expensive only when they’re ignored through a wet season.
Here in San Francisco, fog and salt air do specific things to roofing that inland homeowners never deal with. The marine layer sits on rooftops in the Sunset, Richmond, and Ingleside for hours each morning, keeping asphalt shingles damp long after the sun burns off elsewhere. That persistent moisture, combined with wind-driven rain off the Pacific, means a Tamko shingle in San Francisco ages differently than the same shingle in Sacramento. We see granule loss and curling first on west-facing slopes, and we see flashing failures at chimneys and skylights on nearly every older home we inspect.
Which Tamko Models This Applies To
Tamko makes three main shingle lines you’ll find on San Francisco homes: Heritage (their laminated architectural shingle), Elite Glass-Seal (a mid-tier architectural), and Titan XT (their heavier laminated option with a wider exposure). The compatibility issue that trips up most homeowners: Tamko shingles are sized differently from GAF and CertainTeed, and you cannot mix them on the same slope. A Tamko Heritage shingle measures roughly 13-1/4 inches by 39-3/8 inches with a 5-5/8 inch exposure, while a GAF Timberline runs slightly different. If a roofer tells you they’ll patch your Tamko roof with “shingles that look close enough,” that patch will telegraph through and fail within a season or two.
For Tamko roofs, we recommend staying with OEM Tamko shingles or a documented Tamko-approved equivalent for any visible slope work. For accessories like ridge caps, hip and ridge shingles, and starter strips, we carry Tamko-spec materials because those are where the mismatched-color coverage demands OEM-to-match. Underlayment and flashing can be aftermarket as long as they meet or exceed Tamko’s published spec, which for us means a synthetic underlayment rated for San Francisco’s damp roof deck conditions. We’re an independent contractor, not a Tamko dealer or affiliate, which means we tell you plainly when OEM matters and when an equivalent does the job for less.
Here’s the identification detail most owners miss: Tamko prints the shingle series and lot number on the back of each shingle, not the front. If we’re matching a color, we pull a shingle from a shed stash or an attic leftover and read the back label. Without that lot number, a color match is a guess, even from the same manufacturer. If you have a leftover bundle in your garage, keep it. It saves us a color-match headache and saves you a few days of lead time.
Styles & brands we work with
Signs Your Tamko Roofing Is Failing
- Granules in your gutters or downspouts, especially after rain. Tamko shingles shed granules as the asphalt surface oxidizes. A little granule wash in year one is normal. Heavy granule accumulation every season means the shingle’s protective surface is going, and the underlying asphalt is next.
- Curling or lifted shingle corners on west-facing slopes. San Francisco’s afternoon sun hits west slopes hard, and the repeated wet-dry cycle from fog mornings to sun afternoons makes shingles curl at the corners. Once a shingle curls enough to catch wind, it starts lifting in sheets.
- Water staining on ceilings or in attic sheathing, usually in one corner of a room. Roof leaks travel. What shows up on your ceiling is rarely directly below the failed shingle. We trace water back from the stain, because the actual breach is often six to ten feet away where flashing meets the roofline.
- Missing or shifted ridge cap shingles. The ridge cap is the top course, and it takes the brunt of San Francisco wind off the ocean. If you can see gaps in the ridge cap from the street, water is already getting into the top of the roof assembly.
- Flashing that has pulled away from chimneys, skylights, or vent pipes. This is the most common failure point on San Francisco homes, and it’s rarely the shingles themselves. Flashing sealant dries, cracks, and separates, and once it does, water follows the gap straight into the roof deck.

AfterReplacement Cost & What’s Included
For a targeted Tamko roof repair in San Francisco, expect to pay $470 to $2,125 installed. A full roof replacement in San Francisco runs $9,440 to $23,600 depending on roof size, pitch, number of layers being torn off, and whether we’re replacing just the shingles or the underlayment and flashing as well. Small repairs like replacing a single damaged shingle, resealing a vent pipe boot, or tacking a loose ridge cap shingle sit at the low end. Repairs that involve removing multiple shingle courses, cutting back roof deck sheathing, and rebuilding flashing at a chimney or skylight sit at the high end.
Every Bradford Remodeling Co San Francisco roof job gets a written price before any work starts. That price includes removal of the failed material, disposal, installation of the new Tamko-compatible material, and a written workmanship warranty. No numbers that move at the door. Curtis Lane reviews every roof scope personally before the crew starts, because roof repairs are exactly the kind of job where a missed flashing detail turns a $600 repair into a $6,000 interior water damage claim two months later. If the work fails within the guarantee period, we come back and correct it at no charge under our 365-Day Done Right Promise.
DIY or Call Us?
Roof work in San Francisco is not a ladder-and-caulk-gun job. Most San Francisco homes are two or three stories, roof pitches are steep enough to be genuinely dangerous, and the roof surface is often damp from fog even when the street looks dry. You can safely check for visible signs from the ground or from an upper window: missing shingle tabs you can see, ridge cap gaps against the sky, flashing that’s visibly lifted. What you should not do is climb a ladder with a tube of roofing cement and try to seal anything yourself.
Here’s the honest split: if the failure is one visible shingle on a low, walkable pitch and you have fall protection and the right tools, it’s within reach. If the failure is flashing, underlayment, or anything on a pitch steeper than about 6/12, call us. A fall off a two-story roof changes a repair bill into a hospital bill. Call (831) 610-5598 and we’ll send a crew to look at it, tell you exactly what’s wrong, and hand you a written price.
FAQs
Tamko Heritage shingles carry a 30-year limited warranty, but on San Francisco’s damp, fog-exposed slopes we typically see them holding their seal and granule surface for 15 to 22 years before they need replacement. West-facing slopes and roofs with poor attic ventilation age faster. Call (831) 610-5598 for an exact inspection of your roof’s condition.
Yes, if the failure is localized: a few missing shingles, a failed pipe boot, or flashing that’s lifted in one area. A repair makes sense when the surrounding shingle field is still in good shape. If the shingles are curling across multiple slopes or granule loss is widespread, patching it buys you time, not a fix. We’ll tell you which one you’ve got before we quote any work.
Most Tamko roof repairs in San Francisco are done in a single visit, typically four to eight hours depending on the scope and the number of flashing points involved. If we’re replacing underlayment or cutting out damaged deck sheathing, it can run a full day. We schedule roof work around San Francisco’s fog pattern so materials go down on dry surfaces.
We stock Tamko-compatible shingle colors and Tamko ridge cap and starter materials on our trucks for common San Francisco color mixes. For less common colors or a full re-roof where we need a specific lot number for a clean match, we order from our supplier and it’s typically on site within three to five days. Call (831) 610-5598 and we’ll check your color against what’s on the truck.
If you’ve got a Tamko roof that’s showing signs of trouble, or you’re not sure and want a straight answer, call (831) 610-5598. We’ll inspect it, give you a written scope with a fixed price, and stand behind the work for a full year. Straight number, real scope, no surprises at close-out.
