Full step-and-counter flashing replacement built for Richardson's 1960s—1980s rooflines and its hail, wind, and freeze-thaw cycles.
Richardson's neighborhoods, from Canyon Creek and Cottonwood Heights to the older streets of historic Richardson and Prairie Creek, are full of solid 1960s—1980s ranch and traditional homes. Many of these houses still carry their original chimney flashing, thin metal that has spent decades absorbing North Texas hail, wind gusts, and the freeze-thaw swings that crack mortar and lift metal at the roofline. When that flashing finally fails, a quick smear of roofing tar isn't a fix, it's a delay. Chimney flashing replacement addresses the actual point where roof and chimney meet, so water stops finding its way into the attic and interior walls for good.
Flashing is the metal barrier that seals the joint where a chimney passes through the roof deck. Over time, thermal cycling in Richardson's hot summers and freezing winters expands and contracts that metal until seams open and fasteners work loose. Hailstorms common to the Dallas-Fort Worth area can dent or tear thin flashing outright, and wind-driven rain finds any gap left behind. Homes near the Telecom Corridor and throughout Prairie Creek that still have builder-grade flashing from their original construction are especially due for a look.
A reseal buys time by caulking over existing flashing, but it doesn't address metal that's already corroded or improperly installed. Full chimney flashing replacement is different: it means removing the old material entirely and installing new step flashing along the sides of the chimney and counter flashing that's let directly into a cut mortar joint above it, not just caulked to the brick face. That mortar-set counter flashing is what makes the repair permanent rather than another temporary patch, and it's the same standard we bring to related work like chimney crown repair and chimney leak repair when a leak's source needs to be traced back to its actual origin.
The masonry stock in Richardson is a big part of why flashing work here has to be done right the first time. Ranch and traditional homes built through the 1960s, 70s, and 80s in Canyon Creek, Cottonwood Heights, and historic Richardson are now at the age where crowns, caps, and mortar joints are showing decades of hail impact and freeze-thaw cycling. Flashing that was adequate when the home was built often no longer matches the current roofline pitch or material after a reroof, and cracked mortar joints nearby make it harder for standard flashing to seat properly. In these older neighborhoods we frequently find flashing replacement paired with mortar joint repair or crown repair, since a chimney that's shedding water at the crown is usually also compromised at the flashing line. If you're not sure whether your chimney's issue is flashing, crown, or both, our guide to spotting chimney repair warning signs walks through what to look for from the ground.
If your Richardson home is due for a new roof, flashing replacement should happen alongside it, not before or after on its own. Re-flashing at the same time as a reroof means the step flashing integrates cleanly with new shingles or tile, and the counter flashing can be cut into the mortar joint without disturbing a roof that was just finished. We coordinate directly with roofing crews across Dallas-Fort Worth so the chimney doesn't become the weak point in an otherwise new roof system. This is also a good time to check the chimney cap and crown, since both take the same weather beating as the flashing and often need attention around the same age. See our chimney cap installation page for how that piece fits into the overall seal.

(214) 225-8874Flashing replacement pricing depends on a few real factors: the chimney's height and roof pitch, the type of flashing material used, how much of the surrounding mortar joint needs to be cut and repointed to seat the counter flashing, and whether the work is being coordinated with a reroof already underway. Chimneys on steeper or multi-story Richardson homes take longer to access safely, and older mortar that's already crumbling can add repointing time before flashing can even be installed. All chimney services start at $99, and every job includes an up-front, written price before any work begins, no surprises after the fact.

Water stains on the ceiling or wall directly next to the chimney, especially after a hard rain or hailstorm, usually point to flashing rather than the chimney crown. This is especially common in Canyon Creek and Cottonwood Heights homes with original 1960s—1980s flashing that's never been replaced. A technician can confirm the source before any work is quoted.
Small sections of otherwise sound flashing can sometimes be resealed, but once metal has corroded or pulled away from the mortar joint, a full re-flash is the only permanent fix. Given how many Richardson homes are now decades old, most flashing we see has passed the point where a reseal will hold through another freeze-thaw season.
It doesn't have to, but it's ideal. If you're already planning a reroof on a historic Richardson or Prairie Creek home, coordinating the flashing work at the same time lets the counter flashing get cut cleanly into fresh mortar and tied into the new roofing material.
Yes, dented or torn flashing is a common outcome of the hailstorms that pass through the DFW area, and it's not always obvious from the ground. If your Richardson neighborhood took a recent hit, it's worth having the flashing checked along with the roof.
Most single-chimney flashing jobs are completed in a day, though homes with steep rooflines or mortar joints that need repointing before the counter flashing can be set may take longer. We provide an up-front quote after inspecting your specific Richardson home so there's no guessing on timeline or cost.
