Chimney Flashing Repair in Floresville, 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.

Floresville's Wilson County housing mixes historic downtown homes with rural ranch properties and newer builds in Eagle Creek Ranch and Riverwood, where wood-burning is genuinely used for heat and creosote accumulation runs higher than in the suburbs. That makes the seasonal Level 1 inspection and creosote-class assessment the core of our work here -- a Class 3 glazed deposit is a documented fire hazard, not a maintenance note. Our CSIA-certified technicians measure liner condition and clearance to NFPA 211 on every system before the heating season.
