Tamko Flashing Replacement: The Fort Worth Owner’s Guide
Tamko flashing replacement in Fort Worth typically runs $220 to $480 installed, depending on how many linear feet we’re pulling and what’s underneath. We stock Tamko-compatible flashing on our trucks, so most jobs in Fort Worth are done in a single visit. You’ll usually find the problem after a storm, or when you notice a water stain spreading across the ceiling near a chimney, wall line, or valley.
Flashing is the metal that bridges the gap where your roof meets something vertical, like a chimney, dormer wall, or a vent pipe. Tamko makes quality flashing for their shingle systems, but the Texas sun and Fort Worth hail don’t care what brand it is. Metal expands, sealant dries out, and fasteners back out. When that happens, water finds the gap. Here’s what you need to know before you call anyone.
Which Tamko Models This Applies To
Tamko flashing components are designed to work across their shingle lines, including Heritage, Heritage Proline, and Elite Glass-Seal series roofs. That said, the flashing itself isn’t model-specific the way a shingle color is. What matters is the profile: step flashing for sidewalls, headwall flashing for dormer tops, pipe boot flashing for vents, and valley flashing where two roof planes meet. Tamko’s metal flashing is typically 28-gauge galvanized steel with a baked-on finish, though we also see heavier 26-gauge specified on some luxury shingle installations.
If you’re checking what you have, look for the stamp on a loose piece or any packaging left in the attic or garage from the original build. If the flashing is failing, you’re already past the point of brand loyalty: the question is whether the replacement is OEM Tamko or a quality aftermarket equivalent. For most Fort Worth homes, the aftermarket 28-gauge galvanized step flashing performs identically once installed under the shingles and sealed correctly. What matters more is whether the installer steps it properly: each shingle course gets its own piece of flashing, overlapping the one below, so water sheds down instead of sneaking sideways.

Signs Your Tamko Flashing Replacement Is Failing
- Water staining on ceiling or walls near a chimney or wall line. This is the big one. Flashing doesn’t fail in a showy way, it fails quietly. By the time you see the stain, water has already been finding its way in for a while.
- Lifted or missing step flashing after wind. Fort Worth storms love to peel the outer edge of a piece of step flashing. Walk the yard after heavy weather and look up at the sidewalls. If you see a shadow gap where metal used to sit, water’s already in.
- Dried, cracked sealant around pipe boots and chimney counterflashing. The sun here bakes sealant to a brittle crust in four or five years. Once the seal breaks, the flashing is no longer doing its job even if the metal looks fine.
- Rust bleeding or pitting on exposed flashing sections. Tamko flashing is coated, but hail dents and driving rain eventually wear through. Rust streaks on the flashing or on the shingles below it mean moisture is working on the metal and the seal is compromised.
- Granule piles in gutters along with water spots inside. Flashing failure and shingle wear often happen together on a Fort Worth roof. If you’re cleaning granules out of the gutter and you see stains inside, don’t wait. The flashing may be gone and the decking might already be softening beneath it.

AfterReplacement Cost & What’s Included
In Fort Worth, expect to pay $220 to $480 for a typical single-location flashing replacement: a chimney, a plumbing vent boot, or a 10-to-20-foot run of step flashing along a sidewall. A full roof perimeter flashing job with valleys, drip edge, and multiple penetrations can run higher, and we’ll tell you the exact number before we start.
What drives the range: how much metal we’re pulling and replacing, what condition the decking is in underneath, whether we need to lift and re-seat shingles, and access. A chimney on a two-story roof with a steep pitch costs more than a pipe boot on a single-story ranch. Every Brennan Roofing Co Fort Worth quote is written. That means the price goes on paper before any work starts and it does not move at the door. Parts and labor are listed separately, and the work is covered by the 365-Day Done Right Promise: if it’s not done right, we make it right in writing, at no charge, for a full year.
DIY or Call Us?
Here’s the honest split. You can safely check for visible damage from the ground: look for lifted flashing, gaps around the chimney, cracked sealant on pipe boots, and rust streaks running down from metal edges. That tells you whether you have a problem. Fixing it is a different story.
Flashing replacement means lifting shingles without cracking them, cutting step flashing to the right dimensions, properly lapping each piece, and re-sealing with the right material for Texas heat. Get the lap wrong and you’ve made the leak worse. Get on a steep Fort Worth roof without the right equipment and you’re risking a lot more than a bad repair. If you’re seeing water inside the house, call (682) 900-7902. We’ll walk the roof ourselves, check the flashing and decking by hand, and give you a straight answer before a single shingle comes off.
FAQs
Tamko flashing typically lasts 15 to 20 years in the Fort Worth climate, but sealant joints may need attention every 5 to 7 years. Texas sun and hail cause the metal to expand, contract, and dent, which eventually breaks the water seal. Call (682) 900-7902 if you’re seeing any of the warning signs listed above.
Sometimes a reseal is enough, particularly on pipe boots and counterflashing where the metal is solid but the sealant has dried out. Once the metal is rusted through or bent out of shape from hail, replacement is the only fix that holds. We’ll tell you which path is right for your roof before any work begins.
Most single-location flashing replacements in Fort Worth are done in one visit, usually 2 to 4 hours depending on access and how much shingle lifting is involved. Larger jobs with multiple penetrations and valleys may take a full day. We’ll give you a clear time window before we start.
