From historic downtown McKinney brick to the prefab fireplaces of Stonebridge Ranch and Craig Ranch, we reseal and repair the flashing that keeps roof leaks out.
If you've noticed a water stain creeping across the ceiling near your chimney, or rusty streaks running down the brick after a storm rolled through Collin County, the flashing is usually to blame. McKinney's mix of housing stock makes this a common call — from the turn-of-the-century masonry chimneys in historic downtown McKinney to the large master-planned homes with prefab fireplace systems in Stonebridge Ranch, Adriatica, Craig Ranch, and Tucker Hill. Flashing is the thin metal barrier where your roofline meets the chimney, and in this part of Texas it takes a beating. Lowes Chimney Sweep repairs and reseals flashing throughout McKinney, seven days a week, with services starting at $99.
Flashing repair is specifically about the roof-to-chimney joint — not the chimney structure itself and not a full roof replacement. Over time, the caulk or tar sealant used to bond flashing to brick or siding dries out, cracks, and shrinks. Step flashing pieces can lift at the edges from wind or foot traffic, opening a gap right where water wants to go. Our job is to inspect that joint, determine whether the existing flashing can be resealed or whether sections need to be replaced, and correct the problem so water sheds away from the chimney instead of into your attic or walls.
Not every flashing problem calls for full replacement. If the metal itself is intact and just poorly sealed, a professional-grade resealing with the correct sealant and technique can solve the leak for a fraction of the cost of new flashing. Replacement becomes necessary when the metal has rusted through, been bent out of shape by hail or wind, or was installed incorrectly to begin with — which we see fairly often on newer builds where flashing was an afterthought rather than integrated properly during construction. We'll always tell you which category your chimney falls into before any work begins.
McKinney sits in a part of Collin County that puts real stress on a roof-to-chimney seal. Spring and early summer hailstorms can dent or lift flashing directly, while the high winds that come through ahead of North Texas fronts work at the edges of step flashing until they pull loose. Add the freeze-thaw cycles of a Texas winter, where moisture gets into tiny gaps and expands, and even a well-installed seal can start to fail years before you'd expect. The area's clay soil doesn't help either — as it swells and shrinks with rainfall, foundations and chimneys shift slightly, which can stress the flashing joint even on newer homes in Craig Ranch or Stonebridge Ranch. In historic downtown McKinney, older masonry chimneys often have flashing that's been patched multiple times over the decades and is simply due for a proper repair rather than another temporary fix. Whether your home is a century-old brick build or a newer construction with a prefab fireplace insert, the flashing detail is one of the first things worth checking after a hailstorm or a hard freeze. If you're also seeing crumbling mortar joints nearby, it's worth pairing this with a tuckpointing and masonry repair check, and homes with visible water intrusion further down the flue may need a full chimney leak inspection to rule out other entry points.

If your chimney cap is missing or damaged, water can bypass a perfectly good flashing repair entirely — see chimney cap installation and repair. Homes near Stonebridge Ranch and Adriatica with taller chimney stacks sometimes also need chimney crown repair to fully seal the top of the structure. And if it's been a while since your last inspection, our guide to spotting chimney damage early covers what to watch for between visits.
Flashing repair pricing depends on a few practical factors: whether the existing flashing can be resealed or needs replacing, how much of the flashing run is affected, the pitch and accessibility of your roof, and the type of chimney material we're sealing against — brick, stone, or a prefab surround. A single-story ranch-style roof in a newer Craig Ranch development is generally a faster job than a steep, multi-story roofline over a historic downtown McKinney home.

Leaks near the chimney are flashing-related far more often than they're a general roof problem, especially in McKinney homes after hail or high wind events. The telltale sign is water stains that hug the chimney's edges rather than spreading across the whole ceiling. We check the joint directly during an inspection to confirm before recommending any repair.
It depends on the condition of the metal underneath. If the flashing itself is intact and just poorly sealed, a proper reseal with the right materials solves most leaks. We only recommend replacement when we find rust-through, bent sections from storm damage, or flashing that was installed incorrectly to begin with, which is common on some newer McKinney builds.
Yes — Collin County sees a combination of hail, strong seasonal winds, and freeze-thaw cycles that all work against a flashing seal over time. Clay-soil shifting can also stress the roof-to-chimney joint on both older and newer homes. It's one of the more weather-driven repairs we handle in this area.
Older masonry chimneys in historic downtown McKinney often have flashing that's been patched over the years, so we sometimes find multiple layers of old sealant to remove before doing the job right. The brick itself may also need gentle handling to avoid damage. We treat these repairs with extra care compared to a newer stucco or siding home.
They can, particularly when flashing around a prefab fireplace chase wasn't detailed properly during original construction. Wind and freeze-thaw cycles can loosen even a newer install faster than expected. A quick inspection tells us whether it's a simple reseal or a flashing correction.
