Claim SpotThe joint where the chimney meets the roof is the most common leak point on Cibolo homes. Chimney Operations replaces failed step and counter-flashing properly — cut into the mortar joint and sealed, not caulked over. That matters most with simple gable composition roofs with factory chase covers.

Flashing is where Cibolo chimneys leak most, and locally that means simple gable composition roofs with factory chase covers. Add in flat-land storms that dump water straight onto the chase top, and any gap at the roof line turns into an interior stain. In 2000s and 2010s subdivisions now reaching their first real maintenance cycle we routinely find original builder-grade galvanized chase covers rusting through at roughly the fifteen-year mark, so we cut new counter-flashing into the mortar joint instead of relying on a bead of sealant.
Most flashing leaks we repair in Cibolo were never installed correctly. Surface-applied counter-flashing held on with caulk lasts a few Texas summers before the sealant cracks and shrinks away from the brick.
Heat cycling does the rest. Metal expands and contracts every day across a Guadalupe County summer, working the fasteners loose until water runs behind the flashing and down into the ceiling below.

Yes. Between simple gable composition roofs with factory chase covers, plus flat-land storms that dump water straight onto the chase top, the joint between chimney and roof takes the most abuse of anywhere on the house. We find original builder-grade galvanized chase covers rusting through at roughly the fifteen-year mark regularly across Bentwood Ranch, Cibolo Valley Ranch, Falcon Ridge and Steele Creek.
