IKO Flashing Replacement: The Dallas Owner’s Guide
We stock and install IKO-compatible flashing replacement for Dallas homes, with most jobs running $280 to $640 installed depending on the flashing type, roof pitch, and how much surrounding shingle work is needed. We keep common IKO flashing profiles on the truck, so many replacements are done the same day we arrive. Most Dallas homeowners discover a flashing problem the ugly way: a water stain on the ceiling after a hard rain, granules collecting in the gutter, or a roof leak that only shows up when the wind drives rain from a specific direction.
Flashing is thin metal strips shaped to move water away from the places your roof is most likely to leak: valleys, chimneys, skylights, vent pipes, and the edges where roof meets wall. IKO’s flashing components are built to pair with their shingle lines, and when they fail, they fail quietly. By the time you see the stain inside, the flashing has been done for a while.
Which IKO Models This Applies To
IKO flashing replacement applies across the full IKO architectural and designer shingle lines common in North Texas: Cambridge, Dynasty, Nordic, and the Royal Estate series. The flashing itself isn’t model-specific the way a car part is. What matters is the flashing profile and material gauge matched to the roof penetration, plus the shingle color blend if exposed flashing is visible from the street.
To identify what you have, look for the stamped manufacturer mark on any exposed flashing or check the original roof invoice if you have it. IKO step flashing used on Cambridge roofs is typically 26-gauge galvanized steel, while dormer and chimney flashing on Dynasty installs often uses heavier 24-gauge. The gotcha we see in Dallas: some builders used aluminum flashing with IKO shingles to save money. Aluminum reacts with treated lumber and fails measurably faster in our humidity swings. We replace it with galvanized or painted steel matched to the roof. If you don’t know what’s up there, Greg Holloway walks the roof himself before quoting, so you get a number based on what’s actually installed, not what a brochure assumes.
Tilehurst Roofing Dallas is an independent service provider, not affiliated with IKO. We also stock compatible flashing for GAF, Owens Corning, and CertainTeed roofs, so the truck carries more than one answer.

Signs Your IKO Flashing Replacement Is Failing
- Water stains on ceilings or upper walls after wind-driven rain. This is the classic signal that step flashing along a wall or chimney has lost its seal or was never properly interleaved with the shingles.
- Granules in the gutter concentrated near a valley or wall edge. Failing flashing lets water run underneath shingles in one focused spot, washing granules off the underside faster than normal roof wear ever would.
- Rust streaks or visible corrosion on exposed flashing. Dallas gets enough hard UV and storm-runoff cycling that galvanized flashing eventually sacrifices its zinc layer. Once you see rust, the metal is thinning and pinholes are coming.
- Damp attic insulation near chimneys, skylights, or vent pipes. Flashing at penetrations is the most common failure point on any IKO roof, especially where caulk was used as a shortcut instead of properly lapped metal.
- Shingles lifting or curling at roof-to-wall transitions. If the flashing underneath has shifted or corroded, shingles lose their anchor point and start to lift, opening a direct path for water.
Any of these is worth a look sooner rather than later. Water that gets past flashing doesn’t stop at the roof deck. It finds insulation, drywall, and framing, and the repair bill compounds by the week.

AfterReplacement Cost & What’s Included
Most IKO flashing replacement in Dallas runs $280 to $640 installed. Here’s how that breaks down:
| Flashing Type | Typical Installed Range | What’s Involved |
|---|---|---|
| Pipe boot / vent flashing | $280 – $380 | Remove surrounding shingles, replace boot, re-lay, seal. 60 – 90 minutes. |
| Step flashing (roof-to-wall) | $350 – $550 | Lift shingle courses, replace step flashing pieces, re-set. Half day typical. |
| Valley flashing | $400 – $640 | Remove valley shingles, install new W-valley metal, re-lay IKO shingles. Half to full day. |
| Chimney flashing (partial) | $450 – $600 | Replace face or step flashing. Full chimney re-flash runs higher, quoted on site. |
The range depends on roof pitch, how many shingle courses need to be lifted, and whether the existing flashing was installed correctly the first time. Every quote includes removal and disposal of the failed flashing, new flashing matched to your IKO roof, resealing of lifted shingles, and a written guarantee on the repair before the crew leaves. If the repair fails inside the guarantee period, we come back and fix it at no charge under the 365-Day Done Right Promise. That’s part of the Kingswell Way: say the price before the work, show up in the window we gave, leave the place cleaner than we found it, put the guarantee in writing.
DIY or Call Us?
You can safely check a few things from the ground or with a ladder: look for rust streaks, missing flashing pieces, or shingles that have lifted near walls and penetrations. Do not get on the roof to inspect flashing up close. Roofs in Dallas get brutally hot, and walking on an aging IKO roof without experience risks both your safety and further shingle damage. Flashing replacement means lifting and re-setting shingles, and if you re-lay them wrong you’ve created a leak that didn’t exist before.
There’s a difference between checking and repairing. We’re happy to walk through what you see over the phone at (903) 499-4275. If it sounds minor, we’ll tell you honestly. If it needs a professional eye, we’ll schedule the visit and you’ll have a written price in your hands before any work starts. Price before we touch it. That’s just how a roof conversation ought to start.
FAQs
In Dallas, IKO flashing typically lasts 15 to 25 years depending on the metal gauge, sun exposure, and whether gutters are kept clear. Aluminum flashing runs shorter, often 10 to 15 years, especially in the humidity swings we get. Call (903) 499-4275 and we’ll tell you what’s installed and how much life is left in it.
Caulk and sealant can buy weeks, not years. Once flashing metal is rusted, bent, or pulled away from the wall line, sealant is a band-aid, and it fails again. In Dallas, proper replacement is the repair. Ask us about your specific situation at (903) 499-4275.
Most flashing replacements take 60 minutes to a full day depending on the type and how many shingle courses we lift. Pipe boots and vents are fast. Valley and chimney work takes longer. We’ll give you a time window when we quote, and we show up in it.
Yes. We keep common IKO-compatible pipe boots, step flashing, and valley metal on the truck, along with matching materials for GAF, Owens Corning, and CertainTeed. If we need a specialty profile, it’s typically available same week from our Dallas-area suppliers. Call (903) 499-4275 and we’ll check stock while you’re on the line, with a live person, any hour.
