Tamko Flashing Replacement: The Fort Worth Owner’s Guide
If you’re looking for Tamko flashing replacement in Fort Worth, here’s the short version: we stock Tamko-compatible flashing on our trucks, and most flashing replacements in Fort Worth run between $350 and $900 installed, depending on the type of flashing and how much of it needs to come out. We can typically get to a flashing job within a few days, and you’ll have a written price in dollars before we touch anything.
Most Fort Worth homeowners find out their flashing has failed the hard way: a water stain shows up on a bedroom ceiling after a spring storm, or they spot daylight through a gap where the roof meets a chimney or sidewall. The flashing itself is metal, but the seal around it, the fasteners, and the surrounding shingles all age at different rates in Texas heat. When any one of those gives way, water starts finding a path. Erik Lindgren has pulled enough rusted step flashing off homes near the Fairmount Historic District to know that what looks like a small stain inside usually traces back to a flashing seam that has been quietly failing for a year or two.
Which Tamko Models This Applies To
Tamko flashing is not a one-size-fits-all product. The flashing profile that works on a Heritage shingle line may not seat properly against a Titan XT or StormFighter IR profile, because the shingle thickness and exposure change the way the flashing sits against the roof deck. The compatibility gotcha we see most often in Fort Worth is this: homeowners buy a generic step flashing from a big-box store, and the vertical leg is too short for the shingle’s exposure, so water wicks over the top edge within a season or two. Tamko’s own flashing and recommended accessories are cut to work with specific shingle exposure lines, usually in 4-inch and 5-inch step heights, with 10-foot roll flashing for valleys and sidewalls.
How to identify what you have: look at the shingle wrapper or the install invoice for the model name and the warranty registration code. Tamko shingles carry a label with the product line printed on the wrapper; if that’s gone, we can match the shingle’s profile and exposure by measuring the reveal from the ground during the estimate. As for OEM versus aftermarket: Tamko’s OEM flashing is solid and matches their specs exactly, but quality aftermarket flashing made from 26-gauge galvanized steel or aluminum with the correct step height works just as well and is what we stock most often. The material is not where you save money; the labor to cut, bend, weave, and seal it correctly is where it gets done right or done twice.

Signs Your Tamko Flashing Replacement Is Failing
- Water staining on ceilings or walls near a chimney, dormer, or roof-to-wall intersection. This is the classic flashing failure signal. Water follows the flashing seam downward and shows up inside, often several feet away from the actual leak point.
- Visible rust, lifting, or gaps in flashing metal. Fort Worth’s heat and humidity cycle causes metal flashing to expand and contract, which eventually breaks the sealant bond and invites rust. Once the metal is lifting away from the wall or chimney, water gets behind it within months.
- Granules from your Tamko shingles collecting in gutters near valleys or sidewalls. When flashing fails, water saturates the shingle edges near the flashing, washing granules off faster than the rest of the roof. A concentration of granules in one area is a telltale sign.
- Daylight visible from the attic around penetrations or roof-wall joints. If you can see light through a gap where the roof meets a vertical surface, water is already getting through that opening during the next rain.
- Caulk or sealant that is cracked, peeling, or missing around flashing edges. Previous repairs often rely on roof cement or caulk instead of proper metal flashing. In Texas sun, those sealants break down within two to three years, and the leak returns.
Replacement Cost & What’s Included
Most residential Tamko flashing replacement in Fort Worth falls between $350 and $900 installed. The range depends on three things: the type of flashing (step flashing around a chimney runs lower; a full valley replacement with new metal runs higher), how much surrounding shingle needs to come out to seat the new flashing correctly, and whether the underlying decking is still sound once we expose it. You will see your exact number in writing before any work starts, and that number does not change mid-job unless we both agree in writing to a scope change.
Every flashing replacement includes the new flashing metal, the fasteners and sealant, the labor to remove the old flashing without damaging your Tamko shingles, and a written labor warranty. The work is covered by our 365-Day Done Right Promise: if the flashing isn’t right, we make it right. Erik and the crew will also protect the inside of your home the entire time, shoe covers at the door, drop cloths through the hallway, and a photo of the completed clean-up before we leave. If the dog needs to stay inside, we’ll coordinate the door schedule with you.

What you can safely check yourself: look at the flashing from the ground with binoculars after a storm. Note whether metal is lifting, rusted, or missing sealant. Check for interior stains. That’s the extent of it. Flashing replacement involves removing shingles, cutting and bending metal to profile, and sealing it against a vertical surface, all while working on a sloped roof. A small mistake in the lap direction or sealant placement sends water into your home within months. Fort Worth homes with steeper pitches, including many of the older homes near Fairmount, make the job more dangerous than it looks from the ground.
If a crew is going to be up there anyway, it is usually the same labor cost to have the flashing replaced correctly versus patched with sealant that fails again. Call (682) 990-0964 for a free estimate. We’ll come out, assess the flashing and the surrounding shingles, and give you a written price before we touch a shingle. That is just how the job starts.
FAQs
Properly installed flashing typically lasts 20 to 30 years in Fort Worth, though the sealant around it may need reapplication every 8 to 12 years due to Texas sun and heat cycling. Galvanized steel flashing lasts longer than aluminum in most Fort Worth applications because it resists the expansion stress better. Call (682) 990-0964 if you want us to inspect your flashing and tell you exactly where you stand.
In most cases, no. A sealant-only repair on failed flashing will buy you a few months at best, and the underlying problem, usually metal that has lifted, rusted, or lost its lap, remains. We replace flashing when it has failed because repair has already been tried on most Fort Worth homes we see. If you are unsure whether repair is possible, call (682) 990-0964 for a free assessment.
Most flashing replacements take between half a day and a full day, depending on how much flashing needs to come out and whether we need to work around chimneys, sidewalls, or multiple penetrations. We’ll give you a time window in writing before work starts. Call (682) 990-0964 to schedule a look at yours.
