IKO Flashing Replacement: The Fort Worth Owner’s Guide
IKO flashing replacement in Fort Worth typically runs $350 to $850 installed for a standard penetration (pipe boot, vent, or chimney base), and we usually complete the swap the same day we arrive. Flashing is the metal or synthetic material that seals the seams where your roof meets a vertical surface or a penetration, and when it fails around an IKO shingle system, water gets under the shingles fast. Most Fort Worth homeowners discover the problem the same way: a brown stain on the ceiling after a hard spring storm, or granules washing into the gutter right below a pipe boot. The good news is that flashing failure is localized. You don’t need a new roof. You need the right part matched to your IKO system, installed so it actually sheds water.
Key Takeaways:
- Installed IKO-compatible flashing replacement in Fort Worth: $350 – $850 for most penetrations
- We stock IKO-compatible flashing profiles on our trucks, no special-order wait
- Flashing failure is isolated. The shingles around it are usually fine
- Every replacement comes with the 365-Day Done Right Promise in writing
Which IKO Models This Applies To
IKO’s flashing requirements aren’t unique to one shingle line, but the way IKO systems are spec’d means the flashing has to match the roof’s drainage pattern, not just the shingle brand. Our crews work with flashing replacements on IKO Cambridge, Dynasty, Nordic, and Royal Estate roofs across Fort Worth neighborhoods like Wedgwood, Ryan Place, and Park Glen. The part itself is sized by the penetration, not the shingle: a 1.5-inch pipe boot for a plumbing vent, a 3-inch boot for a furnace flue, step flashing at 4-inch by 4-inch by 7-inch for sidewalls, and 8-inch to 10-inch apron flashing where a lower roof meets a wall.
The compatibility gotcha with IKO systems is the underlayment transition. IKO’s heavier architectural shingles (Dynasty and Royal Estate) have a thicker profile, which means the flashing base has to extend far enough up the vertical surface to stay behind the shingle’s exposure line. Cut that corner and the seal fails within two seasons. We use OEM-equivalent flashing profiles in galvanized steel or aluminum, matched to the existing metal to avoid galvanic corrosion, which is a real problem in Fort Worth’s humidity swings. When a customer asks about aftermarket alternatives, we’re straightforward: quality aftermarket flashing that matches the gauge and profile works fine. What doesn’t work is the thin, box-store flashing that’s 26-gauge or lighter. Those fold under a Texas hailstorm and leak at the fasteners.
One practical note: if you don’t know which IKO line you have, check the shingle wrapper in your garage or look at the cut shingle edge. Cambridge and Dynasty are laminated. Nordic is a 3-tab. Royal Estate has a distinctive shadow line. Travis Oakley reads the roof itself when he walks it, and he checks decking and flashing by hand before recommending anything. That’s the Garrison Code: know what’s actually failing before a single shingle comes off.
Styles & brands we work with






Signs Your IKO Flashing Replacement Is Failing
- Water stains on the ceiling directly below a pipe boot or vent. This is the most common first sign. The rubber collar on a pipe boot dries out and cracks under Texas sun, and the seal at the nail flange lets water run straight down the pipe.
- Lifted or curling flashing edges along a chimney or sidewall. Steel flashing expands and contracts with Fort Worth’s temperature swings. After enough cycles, the nails back out and the metal lifts off the shingle, creating a gap that catches wind-driven rain.
- Rust streaks or pinholes in exposed flashing. Galvanized coating lasts 15 to 20 years in our climate. Once it’s worn through, the metal rusts from the inside out. By the time you see rust streaks, water is already finding its way under the shingles.
- Granules in the gutter below a flashing point. Shingles shed granules when water runs under them and abrades the underside. If you’re seeing a concentrated pile of granules below a wall flashing or chimney base, the flashing has been leaking for a while.
- Mold or mildew on the underside of the decking, visible in the attic. This is the late-stage sign. Flashing leaks don’t always show on the ceiling right away, especially if the water runs down a rafter. By the time you smell must in the attic, the flashing has been failing for months.

AfterReplacement Cost & What’s Included
In Fort Worth, you should budget $350 to $850 installed for a standard IKO flashing replacement. That covers the part, labor, removal of the old flashing, new sealant, and re-seating of the surrounding shingles. The range depends on three things: the type of penetration (a pipe boot runs at the low end, a chimney base with step and counter-flashing at the high end), the roof pitch and height (a two-story steep pitch means more safety equipment and time), and whether the decking under the flashing is rotted and needs a patch.
Here’s how the typical jobs break down:
- Pipe boot replacement: $350 – $450
- Vent or flue flashing: $400 – $550
- Step flashing along a sidewall (per 10-linear-foot section): $450 – $650
- Chimney base flashing (step and counter-flashing): $600 – $850
The price goes on paper before any work starts. That’s the Garrison Standard: no number changes at the door, no surprise line items. Every flashing replacement we do carries the 365-Day Done Right Promise, which means if that flashing fails within a year, we come back and fix it at no charge. In writing.
DIY or Call Us?
Replacing flashing on an IKO roof is not a weekends-and-a-ladder job for most homeowners, and the honest reason is safety. The work happens at the roof edge or on the slope, often working around a chimney or pipe while handling sealant and metal. A fall from even a single-story roof in Fort Worth is a hospital trip. Beyond that, the technical part is what gets people: you have to lift the surrounding shingles without cracking the seal, position the flashing so water always runs over the shingle below and behind the shingle above, and fasten it so the nails are covered by the next course. Get that backward and the flashing leaks worse than before.
What you can safely do is inspect from the ground or from the attic: look for daylight around pipes, check for rust on exposed metal, and note any water staining on the decking. Tell me what the roof is doing, and we’ll figure out what it needs. Then call us at (682) 900-7902, and we’ll walk the roof ourselves before we recommend anything. The estimate is free, and it’s in writing before any work begins.
FAQs
Galvanized steel flashing on an IKO roof in Fort Worth typically lasts 15 to 20 years, though rubber pipe boot collars often need replacement at the 10 to 12 year mark. Our sun and hail accelerate both failures. If your flashing is past year 15, have it inspected.
Small sealant failures at flashing edges can sometimes be patched, but once the metal is rusted through, lifted at the nails, or torn, patch jobs don’t hold. We won’t sell you a repair that fails in six months. When replacement is the right call, we say so plainly.
A standard pipe boot or vent flashing swap takes about 60 to 90 minutes once we’re set up. A chimney base with step and counter-flashing takes two to three hours. Most flashing replacements in Fort Worth are done same-day.
We stock IKO-compatible flashing profiles on our trucks: pipe boots, step flashing, apron, and counter-flashing in galvanized steel and aluminum. We also carry parts for GAF, Owens Corning, and CertainTeed systems, so if your roof is mixed or you’re not fully sure what’s up there, we’re ready to match it.
