Tamko Roof Replacement in San Francisco: What to Know First

Tamko roof replacement in San Francisco typically runs between $14,000 and $28,000 for a full tear-off and re-roof on an average 1,500 to 2,200 square foot home, with most jobs completed in 5 to 10 working days once materials arrive. We’re an independent Tamko service provider, not a factory-authorized installer, which means we recommend whatever Tamko line actually fits your house, your budget, and your fog-belt exposure rather than pushing one series. If you’re researching Tamko replacement because your current roof is failing or nearing the end of its life, this page covers what fails, what it costs, and how we handle the whole job from tear-off to the clean-up photo.

How Tamko Products Fail – and How We Fix Them

• Heritage and Heritage Premium architectural shingles losing granules faster than expected. This is the number one Tamko complaint we walk into in the Sunset and Richmond Districts. The granule loss usually traces back to either a low-slope section holding fog moisture longer than the shingle was designed for, or a batch-age issue where shingles sat in a warehouse for two to three years before install. The granules wash into gutters, the fiberglass mat starts showing through, and the shingle loses its UV shield. We don’t patch granule loss. We tear off and replace, which is the only fix that actually holds on a San Francisco roof that sees 200+ fog days a year.
• Titan XT and StormFighter IR shingles with wind-lift at the rake edges. On exposed ridges in areas like Diamond Heights or Twin Peaks, we see Tamko’s heavier architectural lines lift at roof edges when the original install skipped the starter course or used nails placed too high on the shingle. The tab seals never fully engage, wind gets under the shingle, and you get a slow peel that worsens every winter. Our fix on replacement is a full perimeter inspection of the decking, proper starter strips, and six nails per shingle on high-wind exposures, not four.
• Decking rot caused by trapped moisture under Tamko’s organic-mat shingles. Some older Tamko organic shingles from the 1990s and early 2000s, still on plenty of Mission and Noe Valley homes, hold moisture differently than today’s fiberglass mat products. When those shingles reach end of life, the decking underneath is often soft in places the homeowner never saw from the ground. We inspect every sheet of plywood or OSB during tear-off and replace any decking that won’t hold a fastener, rather than nailing over rot and handing you a problem five years from now.
• Valley and flashing failures around chimneys and skylights on Tamko roofs. This is more about San Francisco’s housing stock than the shingle itself, but it shows up constantly on Tamko replacements. Older Edwardian and Victorian homes have chimney crickets and skylight curbs that were flashed for cedar shake or older dimensional shingles. When a previous contractor reused that flashing with Tamko shingles, the sealant fails within a few seasons. We re-flash every penetration on a Tamko replacement, even if the old flashing looks fine from the ground.
• Tamko’s self-sealing strip failing to bond on north-facing San Francisco slopes. North-facing roof planes in the Outer Sunset, where it stays cool and damp into July, sometimes never get hot enough for the adhesive strip on Tamko shingles to fully activate during install. Shingles lift, water works its way under, and leaks start in what looks like a healthy roof. On replacement, we hand-seal north-facing eaves and valleys with a compatible adhesive. It adds a day to the job and costs nothing in materials, but it stops the problem before the first winter rain.

Our Tamko Roof Replacement Process

1. 1
   Site walk and written findings. Erik Lindgren or a lead technician walks every slope of your roof. We check granule loss, flashing condition, deck softness, and ventilation, then write down exactly what we find before we ever mention a number. You’ll get that document.
2. 2
   Written price for the full job. A fixed number in dollars covering tear-off, decking replacement where needed, underlayment, Tamko shingles, flashing, ridge vent or existing vent adaptation, and disposal. No change orders unless you ask for something new.
3. 3
   Interior protection before we touch a shingle. Shoe covers at the door, drop cloths through the hallway we’ll use, and a plan for pets and kids. If the dog needs to stay inside, we coordinate the door schedule with you.
4. 4
   Tear-off and deck inspection. We strip to the sheathing and inspect every sheet. Rotted or delaminated decking gets replaced. We re-nail any decking that’s loose, then check for proper airflow before laying underlayment.
5. 5
   Installation with the details done right. Starter strips, six-nail patterns on exposed slopes, hand-sealing on north faces, re-flashing at every penetration, and proper valley treatment. Tamko shingles installed to spec, not to speed.
6. 6
   Clean-up photo and final walkthrough. We clear all debris, run a magnet for stray nails, and photograph the completed clean-up before we leave. If anything isn’t right, the 365-Day Done Right Promise says we make it right.

What Tamko Roof Replacement Costs in San Francisco

Most Tamko roof replacements in San Francisco fall within these ranges:

• Heritage architectural shingles, basic tear-off and re-roof: $14,000 to $19,000 on a 1,500 to 1,800 sq ft home.
• Titan XT or StormFighter IR, higher slope or complex roof: $18,000 to $24,000. Steeper pitches and more valleys add labor days.
• Full replacement with decking replacement on 30% of the roof or more: add $3,500 to $8,000 depending on how much plywood or OSB comes out. Older Sunset District homes with original 1950s sheathing often fall in this range.
• Flat or low-slope sections tied into a Tamko replacement: $2,500 to $6,000 extra for torch-down or modified bitumen work.

What moves the price most is decking condition, roof complexity, and whether your current roof has one layer or three. You’ll see your exact number in writing before we start, never an estimate that drifts. Call (831) 228-3330 for a free estimate.
