From the tall chimney chases of Las Colinas to the mid-century rooflines of central Irving, we replace worn flashing with a permanent step-and-counter system — not a temporary patch.
If you own a home in Irving, there's a good chance your chimney flashing has already been tested by something — a spring hailstorm rolling through Valley Ranch, wind-driven rain hammering a tall stucco chase in Las Colinas, or years of clay-soil movement shifting a mid-century chimney in central Irving just enough to crack the seal. Flashing is the thin metal barrier between your roof and your chimney, and when it fails, water doesn't announce itself with a flood — it shows up as a stain, a musty smell, or soft drywall near the fireplace. A proper chimney flashing replacement in Irving addresses the actual failure point instead of masking it, and it's one of the most overlooked repairs on DFW homes.
A lot of leak calls get "solved" with a tube of roofing cement smeared over the old flashing. It buys a season, maybe two, then the caulk shrinks, cracks in the heat, and the leak returns. Chimney flashing replacement is a different approach entirely: we remove the old metal, cut a reglet into the mortar joint, and install new step flashing along the sides paired with counter flashing that's let directly into the brick. That mechanical seal doesn't rely on caulk to keep water out — it relies on physics, the way flashing was designed to work in the first place. This service pairs naturally with chimney crown repair and chimney leak repair when water has already found its way into the firebox or attic.
Irving isn't one type of house, and that matters for flashing work. In Las Colinas and Valley Ranch, newer builds often have tall, exposed chimney chases wrapped in stucco or EIFS, sitting well above the roofline where they take the full brunt of DFW's wind-driven rain and hailstorms. Those synthetic-clad chases need flashing that's properly let into a reglet cut behind the stucco finish, not just caulked to the surface, or water will find the gap within a year. In historic downtown Irving and the older neighborhoods around it, mid-century brick chimneys have settled over decades of North Texas clay-soil movement, which opens tiny gaps between the masonry and the original flashing that were never there when the home was built. Both situations end the same way — slow water intrusion — but they call for slightly different flashing details, which is why a proper inspection always starts with figuring out which kind of chimney you actually have.

(214) 225-8874If your roof is due for replacement, flashing should be handled at the same time. New shingles laid over old, corroded flashing just recreates the same leak point under a fresh roof. We coordinate directly with roofing crews across Irving so the step and counter flashing goes in as part of the reroof sequence — cut into the mortar joint before new roofing material is set, sealed properly, and never patched on as an afterthought. This is also a good time to have a chimney inspection done, since a reroof often exposes crown or mortar issues that are easier to reach while the roof is already open. If your chimney also needs cap work, chimney cap installation is worth bundling in as well.
Flashing replacement pricing depends on a handful of real factors, not a flat rate: the height and pitch of the roof around the chimney, whether the chase is brick, stucco, or EIFS, how much of the old flashing and surrounding mortar needs to be removed, and whether the work is being coordinated with an active reroof or done as a standalone repair. A tall exposed chase in Las Colinas typically involves more scaffolding and metal than a single-story chimney in central Irving. Services start at $99, and every job gets priced after we've actually looked at the chimney — never guessed at over the phone.

Water stains that appear specifically along the chimney's edges, rather than spread across the whole ceiling, usually point to flashing rather than a general roof leak. In Irving, this shows up often after a hard hail or wind-rain event hits an exposed chase in areas like Las Colinas. A close inspection at the chimney-roof junction can usually confirm it on the spot.
Resealing with caulk can buy time, but it's a temporary patch, not a fix, especially on the tall stucco chases common in Valley Ranch that take direct wind-driven rain. Once the metal itself is rusted, bent, or improperly set, a proper step-and-counter flashing replacement is the only way to stop repeat leaks.
Yes. Older mid-century chimneys in central and historic downtown Irving have often settled slightly due to clay-soil movement, opening gaps around original flashing that require re-cutting the mortar joint. Newer Las Colinas builds with stucco or EIFS chases need flashing let in behind the exterior finish rather than caulked to the surface.
It's the ideal time, since flashing sits directly under the shingles and is easiest to install correctly while the roof is already open. We regularly coordinate flashing replacement with reroofing projects across Irving so the two are sealed together instead of layered over old, failing metal.
Cost depends on the chimney's height, the chase material, how much old flashing and mortar needs removal, and whether it's paired with a reroof. Services start at $99, and we provide a Free Online Quote after inspecting the specific chimney, since a tall Las Colinas chase and a single-story central Irving home are genuinely different jobs.
