Chimney Flashing Repair in Lakeway, TX

Flashing is the layered metal-and-sealant system that waterproofs the joint where the chimney penetrates the roof, the single most leak-prone point on the whole structure. It's common to fail because it relies on correct layering and counter-flashing let into the masonry; a single bead of roofing tar instead of proper step and counter-flashing is a temporary fix that fails within seasons. Most 'chimney leaks' originate here, not in the flue.

It takes diagnosis, because water travels before it shows. Flashing leaks typically appear as staining at the ceiling or wall right where the chimney meets the roof and worsen with wind-driven rain, while crown and masonry leaks tend to track down the flue or show as efflorescence on the brick. We trace the actual entry point rather than guessing, since sealing the wrong component leaves the real leak active.

Because counter-flashing is mechanical, not adhesive. Correct flashing tucks counter-flashing into a cut mortar joint in the chimney so water is physically directed over the step flashing and onto the roof, it doesn't depend on a sealant bond that dries, cracks, and lets water behind it. Roof cement smeared over the joint is the repair that looks done and leaks again within a couple of years.

Often not. Water entering at the flashing runs into the roof decking, the framing around the chimney, and down into the structure, rotting wood and feeding the same moisture damage that corrodes flue components from outside the masonry. That's why we treat flashing as part of keeping water out of the entire system, an unaddressed flashing leak quietly damages framing you can't see.

Yes — our crews cover Lakeway's 2 ZIP codes across Travis County, including Rough Hollow, Flintrock Falls, The Hills, plus the surrounding communities.

We offer same-week scheduling across Lakeway, booked by a real person in under two minutes, 7 AM to midnight every day.

Lakeway's hillside custom homes in Rough Hollow and Flintrock Falls were built around large masonry fireplaces and tall exterior chimneys exposed to constant Hill Country wind and temperature swings, which accelerate crown cracking and flashing failure. Our CSIA-certified team prioritizes Level 2 inspections with internal flue video here, since multi-flue stacks and offset smoke chambers are common and routinely hide creosote glazing invisible from the firebox. In The Hills and Lakeway Highlands, we frequently document spalling brick and deteriorated mortar joints that NFPA 211 flags as fire and structural concerns. Chimney Flashing Repair is part of keeping that local housing stock safe, efficient, and up to code.
