The roof-to-chimney joint causes more leaks than anything else. We reseal and repair failing flashing before Dallas rain finds its way inside.
Flashing is the metal and sealant that waterproofs the joint where your chimney passes through the roof — and it's the single most common source of chimney leaks. It's a hard joint to seal: two different materials, roofing and masonry, meeting at an angle that sheds a lot of water. When the sealant dries out, the metal lifts, or the roofing around it ages, water starts working in along the roofline. Flashing repair addresses that joint before the leak reaches your ceiling.
Flashing repair makes sense when the existing flashing is fundamentally sound and the failure is in the sealant or a section that's lifted — we clean, re-secure, and reseal it properly, often with a durable sealant rather than the tar that failed. When the flashing is corroded, was never installed correctly, or you're re-roofing anyway, full flashing replacement — with new step and counter flashing let into the mortar joints — is the lasting fix. We'll tell you which your chimney genuinely needs.
Proper flashing repair across Dallas — not another tar smear.
(214) 225-8874Flashing sits at the intersection of chimney and roof, so timing matters. If your roof is near the end of its life, it's often best to coordinate flashing work with the reroof so it's integrated correctly. If the roof is sound and only the flashing failed, a targeted repair stops the leak without touching the rest of the roof. Because a flashing leak is usually one part of a leak investigation, we confirm the flashing is actually the source — not the crown or another entry point — before we repair it.
A flashing repair is far cheaper than the interior water damage a neglected one causes, and the price depends on the extent of the failure, the flashing type, and roof access. You'll get a clear quote before we start. Because flashing is the leading leak source, catching and resealing it early is one of the best-value repairs a Dallas homeowner can make.

It's the metal and sealant that waterproofs the joint where the chimney passes through the roof. Because it seals two different materials — roofing and masonry — at a water-shedding angle, it's a demanding joint and the most common source of chimney leaks when it fails.
Flashing leaks typically show up as staining along the roofline or ceiling near the chimney, often after wind-driven rain. We confirm it's the flashing — and not the crown, cap, or masonry — before repairing, because treating the wrong source leaves the leak in place.
Roofing tar is a quick fix that hardens and cracks within a season or two under Dallas sun. It looks like a repair but doesn't last. Properly resealing the flashing — or replacing it with step and counter flashing — is what actually stops the leak.
Repair works when the flashing is fundamentally sound and only the sealant or a lifted section failed. Replacement is better when the metal is corroded, was never installed correctly, or you're re-roofing anyway. We assess it and recommend whichever genuinely solves the leak.
If your roof is near the end of its life, yes — coordinating flashing with the reroof lets it be integrated correctly. If the roof is sound and only the flashing failed, a targeted repair stops the leak without disturbing the rest of the roof.
