Tamko Roofing: The San Francisco Owner’s Guide
We stock and install Tamko-compatible roofing products across San Francisco, with a full roof replacement typically running $9,440 to $23,600 depending on your roof’s square footage, pitch, and current decking condition. Most Tamko roof repairs in the city fall between $470 and $2,125, and we carry the common Tamko shingle lines, underlayment, and flashing on our trucks so a straightforward fix can often be wrapped up in a single visit. The way homeowners usually discover their Tamko roof has a problem is unglamorous: a damp spot on the ceiling after a heavy Pacific front, or shingle granules collecting in the gutters after a windy week. We want this page to give you a clear picture of what failed, what it costs to fix, and what the repair actually involves before you pick up the phone.
- Key takeaway: Tamko roof repairs in San Francisco run $470 to $2,125 for most localized issues; full replacements run $9,440 to $23,600.
- Key takeaway: We’re an independent San Francisco contractor, not a Tamko dealer or affiliate, and we’ll match the right Tamko-compatible material to your existing roof without pushing a brand swap.
- Key takeaway: The written price comes before any work starts, every time. No crew shows up and discovers a surprise line item halfway through.
Which Tamko Models This Applies To
Tamko makes two broad families you’re likely to find on homes throughout San Francisco: the Heritage series architectural shingles and the Elite Glass-Seal three-tab line. The Heritage line is the one we see most often in neighborhoods from the Sunset District to Bernal Heights, usually in the 30-year and 50-year weight classes, and it’s the product most owners are calling about when wind or salt air has loosened a run of shingles. The Elite Glass-Seal three-tab is older, thinner, and increasingly rare on city roofs, but plenty of 1990s-era garages and flat-lot bungalows still have it.
Here’s the compatibility gotcha worth knowing: Tamko color lots shift subtly between manufacturing runs, so a bundle bought today will not blend invisibly against shingles that have weathered five years of San Francisco fog. If you’re patching a visible slope, we’ll talk you through whether you want a close-match repair or a slope replacement. In most cases, for a roof that’s past the halfway point of its lifespan, patching with OEM Tamko stock from a fresh lot creates a visible seam that most homeowners would rather not look at every morning. We’ll show you samples on site and let you decide with your eyes, not a color code.
Aftermarket equivalents exist for Tamko underlayment and flashing, and honestly, a high-quality synthetic underlayment from another manufacturer often outperforms the original felt. That’s not brand disloyalty; it’s just what holds up better against the wet winters San Francisco delivers. The shingles themselves we order as genuine Tamko. You came to us with a Tamko roof, and we’ll keep it a Tamko roof.
Styles & brands we work with
Signs Your Tamko Roofing Is Failing
- Curling or lifting shingle edges. This usually shows up first on slopes that get full afternoon sun, which in San Francisco means your south and west faces. The asphalt compound dries out, the shingle loses its grip on the nail line, and wind starts working the edges. Once curling starts, it doesn’t reverse.
- Granule loss in gutters and downspouts. Every asphalt shingle sheds some granules during its first year. But if you’re scooping a half-cup of black grit out of a gutter guard every fall, your Tamko shingles are past their protective prime. Granules are the UV shield; without them, the asphalt beneath degrades fast.
- Water staining on ceilings or attic rafters. This is the one that gets the phone to ring. A single failed shingle tab or a rusted pipe boot can funnel water for months before it shows up as a brown ring on the living room ceiling. By the time you see the stain, the leak has been active for a while.
- Missing shingles after wind events. San Francisco’s west-side neighborhoods catch the brunt of Pacific gusts, and Tamko shingles with degraded sealant strips go first. A missing shingle on a steep slope is not a casual repair. Roofs kill people who treat them casually. Call us before you unclip a ladder.
- Sagging or spongy decking underfoot. If the roof surface feels soft when you walk it (or your contractor tells you it did), water has been getting through the shingle layer for long enough to rot the plywood or OSB beneath. That’s no longer a shingle repair; that’s a decking replacement, and the price moves accordingly.

AfterReplacement Cost & What’s Included
Here are the San Francisco numbers we quote most often, and they’re the same numbers you’ll see on the written estimate before we start.
- Roof replacement (full Tamko tear-off and re-roof): $9,440 – $23,600
- Roof repair (localized shingle, flashing, or boot replacement): $470 – $2,125
- Tile roof repair (if your Tamko roof has tile accents or transitions): $710 – $2,950
What moves the number: roof square footage and pitch (a steep three-story Victorian is not a single-story Sunset rancher), how much decking needs replacing once the old shingles come off, and whether your roof carries multiple layers that need tear-off. San Francisco building code requires decking that can pass inspection once it’s exposed, and we don’t fudge that step to keep a number low.
Every quote includes all materials, labor, debris hauling, and the permit work pulled with the city. The written price you approve is the price you pay. If we find rotted decking mid-job, we show you photos, explain the cost in writing, and wait for your go-ahead before hammering a nail. And the work carries the 365-Day Done Right Promise: if it’s not done right, we make it right.
DIY or Call Us?
Here’s the honest split. What you can safely check from the ground: visible shingle damage, granule buildup in gutters, and daylight coming through attic sheathing. What you should not do: climb a ladder onto a wet or steep San Francisco roof, especially one with loose Tamko shingles. Roofs with a 6/12 pitch or steeper are not a weekend project. Falls from roofs are the leading cause of construction fatalities in this country, and it’s an avoidable statistic. For any repair beyond replacing a single three-tab shingle on a walkable, dry, low-pitch roof in good weather, the tool cost, the safety gear, and the very real possibility of making the leak worse add up fast. Call (831) 480-4497. We’ll come out, assess what the Tamko roof actually needs, write up the number, and you’ll never be guessing what happens next.
FAQs
Tamko Heritage architectural shingles typically last 22 to 28 years on San Francisco homes, depending on sun exposure and salt air; the 50-year rating on the package assumes ideal conditions our fog and wind simply don’t provide. The Elite Glass-Seal three-tab line realistically lasts 15 to 18 years here. Coastal moisture shortens every asphalt shingle’s real-world lifespan, and no manufacturer’s warranty language changes that. Call (831) 480-4497 and we’ll give you an honest read on your specific roof’s remaining years.
Yes, any Tamko roof with sound decking and more than half its expected life remaining is a repair candidate, provided the damage is localized. The decision comes down to what the decking looks like once we’re up there. If the plywood is solid and the shingle loss is limited to one slope, we repair at the $470 to $2,125 range and you get more years out of the roof. If the decking is spongy or the shingles are shedding granules across every slope, patching becomes throwing good money after a failing roof, and we’ll tell you that plainly. Estimates are free, and the written price comes before any work starts.
A localized repair takes half a day to a full day on site; a full tear-off and Tamko re-roof on a typical San Francisco home runs three to six working days depending on the roof’s size, pitch, and how many men can work it safely. San Francisco weather dictates the pace, and we don’t work a roof in rain because the underlayment needs dry conditions to seal correctly. We’ll give you a day-by-day schedule with the written estimate, including which days the crew will be loud and which days are quiet.
We stock common Tamko Heritage shingle bundles, starter strips, ridge caps, synthetic underlayment, pipe boots, and step flashing on our trucks, so most San Francisco repair calls are a one-trip job. For full replacements or uncommon color lots, we order genuine Tamko from our supplier and schedule the job once the material is confirmed. If you’re not sure what you have, call (831) 480-4497 and describe the roof; we’ll tell you what we can match before we even schedule the visit.
We also work with named-brand materials from KraftMaid, Cambria, and Silestone when a roofing repair overlaps into attic conversion or interior finish work, and those carry the same written-price promise as every other line item. The goal is simple: a Tamko roof that keeps your family dry for another twenty-plus years, with the price on paper before a single shingle comes off the stack.
