Tamko Flashing Replacement Nationwide

Tamko Flashing Replacement: The San Jose Owner’s Guide

Tamko flashing replacement in San Jose typically runs $320 to $680 installed, depending on where the flashing sits, what’s behind it, and whether the surrounding shingles or tiles need to come up. We stock Tamko-compatible flashing profiles on our trucks, and most straightforward replacements are finished the same day we arrive. The way owners usually find out is not dramatic: a faint water stain on the ceiling, a curl of paint peeling near a wall junction, or granules collecting at the bottom of a downspout after two dry weeks. These are the quiet signals that the metal has lost its seal and water is finding another path. If you’re already seeing stains, the flashing stopped doing its job months ago.

Which Tamko Models This Applies To

Tamko flashing is not one universal piece. It varies by roof system, and matching the right profile matters more than most homeowners expect. The most common matchup in San Jose is Tamko Heritage and Elite architectural shingle lines, where the step flashing gets woven between each shingle course at sidewalls and the metal sits at 4 inches by 4 inches by 8 inches per piece. Tamko’s MetalWorks steel shingle and tile systems use a different profile entirely: wider, lower-pitched flashing pans with a factory Kynar finish that needs to match the panel color, not just the metal gauge. If you have a Tamko rolled roofing or low-slope system, the flashing at the eave and parapet transitions is manufactured to a radius that aftermarket flat stock does not bend to cleanly. The practical rule: if the original flashing is exposed and painted to match the roof color, order the OEM Tamko piece. If it is hidden step flashing or pipe flashing, a high-gauge aftermarket equivalent performs the same and saves $80 to $150. To identify what you have, check the underside of any lifted shingle for a Tamko stamp, or look at the original roofer’s paperwork for the shingle line name. When you call us, Greg Holloway will ask you to describe where the leak shows up relative to the wall, chimney, or pipe, and what the exposed metal looks like. That is usually enough to narrow it to the right part before we climb up.

Signs Your Tamko Flashing Replacement Is Failing

• Water staining on ceilings or upper walls after any real rain. In San Jose, this is often the first sign, and it appears at the wall-to-roof junction or around a chimney, not in the middle of the room. The flashing has lost its seal or a nail has backed out, and water is traveling along the framing before it shows itself.
• Curled, lifted, or missing step flashing at sidewalls. Neighbors see this plain as day. Each piece of step flashing tucks under a shingle course, and over four or five dry California summers the metal expands and contracts enough that pieces start to pull away. Once one piece lifts, the shingle above it loses its lock and wind gets under everything.
• Rust streaks or pinholes in exposed flashing at chimneys or skylights. Tamko’s steel flashing holds up well, but the South Bay gets enough marine air intrusion and tree debris that exposed metal collects moisture. Rust streaks are the warning sign; pinholes are the failure.
• Granules from the shingles piling in the gutter alongside metal flashing pieces. When the flashing moves, the shingle edges around it dry out and shed granules faster. You will see the mix of black granules and small metal slivers in the gutter below the problem area.
• Caulk or sealant slathered around pipe boots that keeps cracking. This is the do-it-yourself repair that fails over and over. The rubber boot around the pipe has split, and no amount of sealant fixes a split boot. The flashing itself needs to come out and a new pipe boot collar needs to be set under the shingles above the pipe.

Replacement Cost & What’s Included

For a typical single-area Tamko flashing replacement in San Jose, here is the real-money breakdown: step flashing replacement at a sidewall runs $320 to $520; chimney flashing (base, counterflashing, and reglet work) runs $480 to $680; pipe boot flashing replacement runs $280 to $400. These prices include the parts, the labor, the removal of the old flashing, replacement of any damaged shingles or tile around the flashing, and a written guarantee on the work. What drives the range: how many courses of shingles need to come up, whether the decking underneath has rotted and needs a patch, and whether the original flashing was set with enough reveal to reuse the existing cuts. When the decking is soft, we tell you before we proceed and the written price you have in hand gets updated in writing, not by surprise. We give the written price before any work starts, and the guarantee is handed to you before the crew leaves. You will know the number before a single nail is driven.

DIY or Call Us?

You can do one useful thing yourself: document what you see. Photo the flashing from the ground, note where the interior stain is, and check if the metal looks rusted or lifted. Then stop. Flashing replacement walks a fine line on a roof, and the consequence of a mistake is water running inside your walls for months before you know it. On a two-story San Jose home with a 5:12 or steeper pitch, working at the eave line with flashing tools and a bundle of shingles is not a weekend project. You need to unseal shingle courses, reset nails in the right pattern, and flash corners so water sheds the way the manufacturer intended. We have seen more than a few homeowner repairs where the new flashing looked fine from the ground and leaked from the top edge because the shingles were re-nailed in the wrong spot. If you want to talk it through first, call (669) 274-0078 and we will give you a straight read on what you are dealing with before anyone schedules anything.
