Serving Canyon Creek, Cottonwood Heights, historic Richardson, and Prairie Creek — expert flashing repair for the roof-to-chimney joint that keeps aging homes dry.
Richardson's roofline tells a story of decades — the low-slung ranch homes of Canyon Creek and Cottonwood Heights, the brick traditionals of historic Richardson, and the mixed housing stock near the Telecom Corridor and UTD all share one common weak point: the metal flashing where the chimney meets the roof. After years of North Texas hail, wind-driven rain, and freeze-thaw cycles, the caulk or tar that once sealed that joint dries out, cracks, or lifts away from the brick. When that happens, water doesn't wait for permission — it finds its way into the attic, the ceiling, and eventually the framing around the chimney. Lowes Chimney Sweep repairs and reseals flashing throughout Richardson, and we can usually tell you on the spot whether your flashing needs a simple reseal or a full replacement.
Flashing failure rarely announces itself with a dramatic leak on day one. It usually starts small and gets worse with every storm that rolls through Collin County.
If you're already seeing water intrusion, it's worth pairing a flashing inspection with a broader chimney inspection to rule out related issues like a damaged chimney crown or cracked cap.
Not every flashing problem calls for tearing the old metal out. When the flashing itself is still straight, rust-free, and properly lapped under the shingles, a professional resealing — stripping old caulk and tar and applying a proper sealant along the counter-flashing and step flashing — can solve the leak for a fraction of the disruption. This works especially well on newer roofs where the flashing was installed correctly the first time but the sealant has simply aged out.
Full replacement becomes necessary when the flashing has rusted through, been bent or pulled loose from wind or a fallen limb, or was undersized or poorly installed to begin with — something we see fairly often on older homes in historic Richardson that have been re-roofed once or twice without the flashing being redone to match. We'll tell you plainly which category your chimney falls into before any work starts, and we don't upsell a replacement when a reseal will genuinely hold.
Richardson's building boom in the 1960s through 1980s left the city with a huge number of ranch and traditional homes carrying original or once-replaced masonry chimneys. In Canyon Creek and Cottonwood Heights especially, many of these chimneys and their flashing are now decades old — right at the point where crowns, mortar joints, and roof-to-chimney seals need real attention. Add in Richardson's regular hail and high-wind storms, plus the freeze-thaw swings that crack sealant and loosen metal over a Texas winter, and it's easy to see why flashing failures show up so consistently across the city, from the older lots near Prairie Creek to the busier rooflines around the Telecom Corridor near UTD. A cracked chimney crown or worn mortar joints, both common in this age of home, often make flashing leaks worse by giving water more paths to travel once it gets past the seal.
Every flashing job starts with a close look at the roof-to-chimney joint from both the roof surface and the attic side, since leaks don't always show up where they enter. From there we determine whether a reseal or replacement is the right call, address any related concerns like a failing chimney cap or deteriorating masonry, and complete the repair so the joint is properly sealed against wind-driven rain and ice. If there's already been water intrusion, we'll also flag any signs of interior damage so you know exactly what you're dealing with — details we cover in more depth in our post on signs your chimney is leaking.
Fast, honest flashing repair for homes across Richardson, from Canyon Creek to historic Richardson.
(214) 225-8874There's no single price for flashing repair because every roof and chimney is different. What we look at includes whether the job is a reseal or a full replacement, how steep or accessible the roofline is, how much of the flashing (step, counter, or both) needs work, the condition of the surrounding shingles and mortar, and whether there's already interior damage to address. Homes in older Richardson neighborhoods with original 1960s–1980s chimneys sometimes need more extensive work simply due to age, while a home with a newer roof may only need a straightforward reseal.

Flashing leaks typically show up as staining on the ceiling or wall right where the chimney passes through the roofline, rather than inside the firebox. In Richardson homes with original 1960s–1980s chimneys, it's common for both flashing and mortar joints to be aging at once, so we check both during an inspection.
If the metal flashing is still straight, unrusted, and properly installed under the shingles, resealing the caulk or tar joint is often enough. Replacement is needed when the metal itself has rusted, bent, or pulled loose — something we see more often on older homes in historic Richardson that have been re-roofed without redoing the flashing.
Yes — hail and high winds common to the Richardson area can lift or dent flashing, and the freeze-thaw cycles each winter expand and contract cracks in old sealant until water gets through. It's one of the main reasons flashing that looked fine a few years ago can start leaking now.
It's a good idea, since many chimneys in these neighborhoods are now decades old and the sealant fails before homeowners notice any staining. Catching worn flashing early usually means a simple reseal instead of dealing with attic or ceiling damage later.
