From Dalworth's mid-century rooftops to the new builds of Mira Lagos, we reseal and repair chimney flashing worn down by Grand Prairie's hail, wind, and shifting clay soil.
If there's a damp stain creeping across the ceiling near your chimney in Grand Prairie, the flashing is usually the first suspect. Between Dalworth's older roof-chimney joints, the Peninsula's lakeside wind exposure, and the newer masonry stacks going up in Mira Lagos, flashing takes a beating differently depending on where you live — but the fix is almost always the same: reseal what's failing, or replace what's too far gone. Lowes Chimney Sweep handles both, seven days a week across the DFW mid-cities.
Grand Prairie sits right in hail alley, and that matters more for flashing than most homeowners realize. Hail doesn't just dent gutters — it dings and lifts thin metal step flashing along the roofline, breaking the seal that keeps water out. Add in the high, gusty winds that roll through the mid-cities and you get flashing edges that work loose over time, especially on the older mid-century homes scattered through Dalworth and Westchester where the original flashing may have been installed decades ago.
South Grand Prairie tells a different story. Newer master-planned neighborhoods like Mira Lagos and the Peninsula have younger chimneys, but Texas clay soil doesn't care how new the house is. As the ground expands and contracts with our wet-dry cycles, foundations shift slightly, and that movement can pull a chimney a hair's width away from the roofline — just enough to crack caulk or tar that was sealing the joint. Whether your chimney is masonry or prefab, that roof-to-chimney seam is the weak point.
Homeowners often assume these issues call for full chimney leak repair, but if the masonry and crown are sound, the flashing itself is frequently the entire problem.
Not every flashing problem needs new metal. If the flashing itself is intact but the seal has failed — cracked caulk, dried-out tar, a lifted edge here or there — resealing with proper roofing cement and counterflashing is usually enough, and it's the more affordable path. We check this before recommending anything more involved.
Replacement becomes the right call when the flashing has rusted through, been bent or torn by hail, or was installed with the wrong technique to begin with (a common issue on older Grand Prairie homes where step flashing was never properly layered with the shingles). In those cases, resealing is just a temporary patch on a bigger problem, and we'll tell you that upfront rather than sell you a fix that won't hold through the next storm season.
It's easy to lump all chimney leak sources together, but flashing repair specifically targets the roof-to-chimney joint — not the top of the chimney. If your issue is water coming down inside the flue itself, that's more likely a cracked crown or a missing chimney cap. We'll always inspect the full system, including the masonry itself, before we tell you flashing is the fix — that's part of an honest chimney inspection.
Grand Prairie's hail and wind don't wait, and neither should a failing flashing seal.
(214) 225-8874We don't post fixed prices because flashing repair costs genuinely depend on what we find. A simple reseal with fresh caulk and roofing cement on an otherwise sound flashing job costs far less than a full step-flashing replacement that requires pulling shingles and re-layering metal. Other factors that affect the price include:
Services start at $99, and every job begins with an honest look at the joint before we recommend reseal versus replacement.

Flashing leaks typically show up as stains on the ceiling near where the chimney meets the roofline, while crown leaks usually appear inside the firebox or flue. We inspect both during a visit since homes in Dalworth and Westchester often have aging flashing and crowns from the same era. Getting the source right the first time saves you from paying for the wrong repair.
Yes — Grand Prairie sits in hail alley, and hail impacts are one of the most common reasons we see lifted or dented step flashing on service calls here. Even small dents can break the seal at the roof-to-chimney joint, letting water in during the next rain. It's worth having flashing checked after any significant hailstorm, especially on older roofs.
It depends on the condition of the metal itself. If the flashing is intact and only the caulk or tar seal has failed, resealing is usually enough and is the more affordable option. If the metal is rusted, torn, or was installed incorrectly to begin with — something we see on some older mid-century Dalworth homes — full replacement is the more lasting fix.
It can. As clay soil expands and contracts through Texas wet and dry seasons, it causes slight shifting in foundations and chimney structures, which can crack the caulk or sealant at the flashing joint over time. This is something we watch for on chimneys across south Grand Prairie's newer developments like Mira Lagos, not just older homes.
We serve Grand Prairie and the surrounding mid-cities seven days a week, including Sundays, so you're not stuck waiting through a weekend with an active leak.
