This page is for San Francisco homeowners whose Tamko roof has a specific problem: a leak over the kitchen, shingles that tore loose in a winter storm, flashing that’s pulling away from a chimney. Not a full tear-off. Not a sales pitch. A repair, done right, in writing.

How Tamko Products Fail – and How We Fix Them

Tamko makes solid shingles, but every product line has its known weak points. In San Francisco, our techs see the same failure patterns repeat across neighborhoods from the Richmond to Bernal Heights. Here’s what actually goes wrong:

• Heritage Vintage shingle granule loss and curling. The Heritage Vintage line is a heavier architectural shingle, but after a decade of San Francisco fog-wet-and-dry cycles, the asphalt starts losing granules and the corners curl upward. Once the granule layer goes, UV breaks down the asphalt fast. We replace the affected shingles individually when the field is sound, which saves thousands over a premature reroof.
• Heritage Proline edge lifting at the drip edge. We see Proline shingles lift at the eaves on north-facing slopes in the Sunset and Richmond, where roofs stay damp longest. The cause is usually inadequate starter strip or nail placement too high in the shingle. The fix is to resecure the lifted edge, correct the nailing pattern on any loose shingles, and verify the drip edge isn’t trapping water.
• MetalWorks stone-coated steel panel seam separation. On flat and low-slope portions of San Francisco roofs, MetalWorks panels can separate at the seams after years of thermal expansion and contraction. The telltale sign is a leak that shows up only after a hot day followed by a cold night. We reseat the panels, replace the sealant with a marine-grade product that handles movement, and retorque the fasteners to spec.
• Flashing failures at chimneys and skylights on Tamko roofs. No shingle fails as often as the flashing around a penetration. On Tamko roofs in the Mission and Noe Valley, we regularly find step flashing that was never properly woven into the shingle courses, or counterflashing that has pulled loose from mortar. We cut the flashing out, install new, and make sure every piece laps the shingle below it, not the reverse.
• Vent boot cracking at the pipe collar. The rubber collar around plumbing vent pipes dries out and splits, usually within 12 to 15 years regardless of shingle brand. On Tamko roofs, when the boot fails, water runs inside the pipe chase and shows up as a ceiling stain below a bathroom. The fix is a new boot, sealed properly, and a check that the pipe isn’t rusted underneath.

Our Tamko Roof Repair Process

Every Tamko repair we do in San Francisco follows the same steps, and you’ll know the price at step one. Here’s how it works:

1. 1
   You call, you get a live person. No voicemail, no callback queue. We take your information and schedule a time that works.
2. 2
   We inspect the roof and find the real cause. Not just the wet spot on the ceiling. We trace the water path back to the source, which on a Tamko roof is often a flashing detail or a boot failure, not the shingle itself.
3. 3
   We write the price down before any work starts. You get a line-item quote in writing. It does not move at the door. If we find additional damage mid-repair, we stop, show you photos, and get your approval before spending another dollar.
4. 4
   We make the repair with the right parts. When matching Tamko is possible, we match. When Tamko has discontinued a color or line, we’ll show you the closest available match from Tamko or another manufacturer and get your sign-off before installing it.
5. 5
   We test the repair. Every repair gets water-tested before we leave. If it leaks during the test, it leaks in front of us, not in your hallway at 3 a.m.
6. 6
   You get the 365-Day Done Right Promise in writing. If the repair fails within one year, we come back and make it right at no charge. That’s not a verbal promise. It’s on paper.

What Tamko Roof Repair Costs in San Francisco

Here’s what you should expect to pay for common Tamko repair scenarios in San Francisco. These are honest ranges, not teaser numbers to get us in the door:

• Individual shingle replacement: $350 to $650 depending on access and how many shingles are involved.
• Pipe boot or vent boot replacement: $250 to $450 per boot, including sealing.
• Flashing repair at a chimney or skylight: $600 to $1,400 depending on the size of the penetration and whether new flashing must be fabricated on site.
• Valley repair: $500 to $1,200 if the valley metal or woven shingles are compromised.
• Flat roof patch on a Tamko MetalWorks area: $400 to $900 for a sealed patch, more if the seam has opened and requires panel refastening.

What moves the price: roof access and pitch, how many stories, whether we can match your shingle from stock, and whether the damage is isolated or has spread. A roof with two layers of old shingles that need a tricky color match will cost more than a simple single-layer repair. Call (831) 318-8819 and we’ll give you an exact number in writing before anything starts.

Why San Francisco Homeowners Call Brennan Roofing Co San Francisco for Tamko Work

We’re not going to tell you we’re the cheapest. We’re not. What we’ll tell you is this: the price you get is the price you pay, it’s in writing before any work starts, and the technician who shows up is background-checked, uniformed, and knows Tamko products well enough to tell you honestly what needs fixing now and what can wait two seasons. Travis Oakley and his crew have been working San Francisco roofs long enough to know that a leak in the Outer Sunset is a different job than a leak on a flat roof in the Mission, and we quote accordingly.

If your Tamko repair requires a matching shingle that’s no longer available, we’ll be straight with you and walk you through alternatives, including GAF, Owens Corning, and CertainTeed options that can work without compromising the look of your roof. We’ll never sell you a reroof when a repair fixes the problem.
