IKO Flashing Replacement in Dallas, TX

IKO Flashing Replacement: The Dallas Owner’s Guide

IKO flashing replacement in Dallas typically runs $280-$520 installed, depending on the linear footage and whether we’re working around existing IKO Cambridge, Dynasty, or Armourshake shingles. We stock IKO-compatible step flashing, counter flashing, and drip edge profiles on every truck, and most replacements are completed in a single visit. Most Dallas homeowners discover the problem during a hard rain, when water shows up at a wall intersection or chimney shoulder that used to stay dry.

Clint Harwell, our owner, grew up in Oak Cliff working on flat-roof rowhouses and learned early that flashing is where a roof lives or dies. In Dallas, the combination of summer UV cycling and spring hail events works the metal hard. IKO’s galvanized steel and aluminum flashing lines hold up well, but the expansion and contraction across 100-degree temperature swings eventually fatigues the bends. When that seal breaks, water follows the path of least resistance straight into your wall cavity.

Which IKO Models This Applies To

IKO flashing isn’t one-size-fits-all. The part you need depends on your shingle line and the roof feature being protected.

Cambridge and Cambridge Cool use standard 8-inch by 10-inch step flashing in galvanized steel, typically 26-gauge. Dynasty and Armourshake installations often require wider 10-inch by 12-inch profiles because of the thicker shingle exposure. For Marathon Ultra AR and other IKO three-tab lines, the original spec was 7-inch by 8-inch, though we rarely see those in Dallas anymore.

Here’s how to identify what you’ve got: check the shingle label strip under the first course, or look for an IKO lot number stamped on the back of a loose shingle. If you can’t find it, measure the exposed shingle height and the wall clearance you need. The wrong width means either inadequate coverage or a profile that won’t seat flat.

We carry both IKO OEM flashing and quality aftermarket equivalents from Phoenix and Boral. For most Dallas repairs, the aftermarket spec matches IKO’s gauge and galvanized coating weight at a lower parts cost. If you’re under IKO’s Iron Clad Protection period, we’ll use OEM to keep your coverage intact. Ridgeline Roofing Co. of Dallas is an independent service provider, not affiliated with IKO.

Signs Your IKO Flashing Replacement Is Failing

• Water stains on interior walls or ceilings near chimneys, dormers, or sidewalls. This usually means step flashing has separated from the wall or the shingle overlap has shifted. In Dallas, the clay soils cause subtle foundation movement that cracks sealant joints and works flashing loose over five to seven years.
• Rust streaks running down the brick or siding below a roof-wall joint. IKO’s galvanized flashing carries a G90 coating, but once the zinc layer is breached, rust accelerates fast. We’ve replaced 12-year-old flashing in Lakewood that looked fine from the yard but was perforated at the bend.
• Lifted or cupped shingles at the wall edge. When flashing pulls away, shingles lose their anchor point and start to curl. This is common on south-facing slopes in Dallas where thermal cycling is most aggressive.
• Visible gaps where caulk or sealant has dried and fallen out. IKO installations rely on proper shingle overlap more than caulk, but counter flashing tops still need a seal. Once that bead cracks, wind-driven rain gets direct access.
• Musty smell in attic spaces after rain, especially near gable ends. This often traces to drip edge flashing that has pulled back from the fascia, letting water run behind the gutter and into the soffit. In older Dallas neighborhoods like Kessler Park, original fascia boards are sometimes soft enough that nails won’t hold.

Replacement Cost & What’s Included

What drives the range: accessibility (steep pitch, tight quarters), whether we need to remove and reset existing IKO shingles, and whether the underlying wall sheathing needs attention. Every estimate includes the flashing material, labor, shingle reset or replacement as needed, and sealant. The number we quote is the number on the invoice. Our 90-Day Done Right Promise covers the workmanship, no paperwork, no arguing.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can check for the symptoms above from the ground with binoculars, or from the attic with a flashlight during daylight. Look for daylight at wall joints, rust on exposed metal, or water trails on rafters. Document what you see with photos.

What you should not do: climb onto a Dallas roof in summer heat, work around a chimney on a slope steeper than 4:12, or try to bend and seat new flashing without knowing how IKO’s shingle exposure pattern works. Flashing replacement means disturbing the shingle course above it, and one misstep tears the mat or breaks the sealant bond. We do this work in uniform, with harnesses and toe boards, and we still respect the height.
