IKO Flashing Replacement: The Fort Worth Owner’s Guide
IKO flashing replacement in Fort Worth typically costs $275 to $625 installed for a standard pipe boot, valley, or step flashing repair, and our trucks carry IKO-compatible flashing stock so most jobs are finished the same day we arrive. You’ll usually discover a flashing failure the way most Fort Worth homeowners do: a water stain on the ceiling after a spring thunderstorm, a curled corner of shingle near a wall junction, or a drip that shows up only when rain drives from the north. Flashing is the thin metal or rubber piece that seals the seams where your roof meets a chimney, wall, pipe, or valley – when it fails, water gets in even if your shingles look fine from the ground.

Which IKO Models This Applies To
Flashing is not tied to one IKO shingle series, so this applies whether your roof wears IKO Cambridge, Dynasty, Nordic, or Royal Estate shingles. What matters is the flashing type and the penetration it seals. IKO’s own installation specs call for step flashing at sidewalls in 4 to 6-inch increments, pipe boots sized to the vent diameter (typically 1.5 or 3 inches for residential), and valley flashing that extends at least 8 inches on each side of the valley centerline. You can identify what you have by looking in the attic at a wall junction or around vent pipes: step flashing shows as a series of small metal rectangles tucked under each shingle course, while pipe boots are rubber collars visible around plumbing vents. We use OEM-spec IKO flashing when the roof is newer and under warranty, and quality aftermarket equivalents from the same gauge galvanized steel or aluminum when the roof is older and the warranty has lapsed. Independent of IKO, we match gauge and profile first. A surprising number of flashing failures in Fort Worth are not the flashing at all but a mismatch – a 3-inch boot stretched over a 4-inch vent, or step flashing cut too short to keep water from wicking behind it.
Styles & brands we work with






Signs Your IKO Flashing Replacement Is Failing
- Wall-side staining along a chimney or dormer. When step flashing loses its seal, water runs behind it and shows up as discoloration on interior walls below the roofline, often appearing days after heavy rain.
- Dark streaks or soft decking around vent pipes. A cracked or sun-brittled rubber pipe boot lets water follow the pipe down through the roof, and the plywood around it starts to feel spongy or shows dark water rings from the attic side.
- Lifted or curled shingle edges near a valley. Valley flashing that has pulled away or corroded lets the shingle corners along the valley lift, which turns a water channel into a water catch.
- Mineral granules piling in gutters below a wall junction. Water sneaking behind step flashing washes granules off the shingles above it, so a sudden granule buildup in one gutter section points to a flashing problem uphill from that spot.
- Attic mustiness after a rain, with no obvious roof hole. Flashing leaks are slower and more diffuse than a missing shingle, so the first sign is often an odor or very faint ceiling discoloration that grows over several storm cycles.
Replacement Cost & What’s Included
In Fort Worth, a single pipe boot replacement typically runs $275 to $375 installed. A section of step flashing along a wall or dormer usually lands between $350 and $525 depending on length and roof pitch, and a valley flashing replacement runs $450 to $625. The range is driven by how much shingle material we have to lift and reset, the roof’s slope (steeper pitches take more setup), and whether the decking beneath has rotted and needs a section replaced before new flashing goes down. You’ll receive a written price in dollars before any work starts, and that number includes parts, labor, cleanup, and the 365-Day Done Right Promise on our workmanship. If your flashing failed because water was getting behind it for months, we’ll tell you honestly whether the decking needs repair and show you what we found, with a photo, before we close anything up.

You can safely check a few things yourself: look in the attic on a dry day for dark rings around vent pipes, and from the ground you can sometimes spot visible gaps between a wall and the shingle line. What gets risky is trying to peel back shingles and slide new flashing in without tearing the shingle, breaking the seal strip, or leaving a nail hole that becomes a new leak. Flashing work on a Fort Worth roof also means working at height with tools and materials, and a fall off a two-story pitch is not worth saving a few hundred dollars. If you want to know what you’re dealing with before you commit to anything, call us at (682) 990-0964 and we’ll walk the roof, show you photos of what we find, and give you a price before we touch a shingle.
FAQs
Properly installed galvanized steel flashing typically lasts 20 to 30 years in North Texas, but rubber pipe boots often crack and fail between 10 and 15 years because our summer heat bakes the rubber until it loses its flexibility. If your roof is over 15 years old and you have not replaced any pipe boots, they are the most likely flashing failure point. Call (682) 990-0964 for an inspection and an exact price.
Sometimes a pipe boot can be sealed with a urethane flashing patch and last a few more years, but a cracked boot or separated step flashing generally needs replacement because patching does not restore the mechanical seal that keeps water out. We will tell you if a repair will actually hold or if replacement is the honest fix. Call (682) 990-0964 and we’ll give you a written price either way.
A single pipe boot swap takes about 1 to 2 hours, while a step flashing or valley flashing replacement along a wall runs 3 to 6 hours depending on how much shingle material we have to lift and reset. Most flashing replacements are finished in one visit. We will give you a clear time window and a written price when you call (682) 990-0964.
Yes, our trucks carry IKO-compatible flashing in common gauges, profiles, and vent sizes, along with flashing products from GAF, Owens Corning, and CertainTeed. That means most flashing replacement jobs are completed the same day without a second visit or a parts run. Call (682) 990-0964 and we will confirm what we have for your specific roof before we schedule.
