Chimney Flashing Repair in Leon Valley, TX
The joint where the chimney meets the roof is the most common leak point on Leon Valley homes. Chimney Operations replaces failed step and counter-flashing properly — cut into the mortar joint and sealed, not caulked over. That matters most with low-slope roofs that hold water instead of shedding it quickly.

Flashing Failures On Leon Valley Roofs — Heavy Rain Finds Every Weak Point
Flashing is where Leon Valley chimneys leak most, and locally that means low-slope roofs that hold water instead of shedding it quickly. Add in the flash flooding and heavy downpours Leon Valley is known for, and any gap at the roof line turns into an interior stain. In 1960s–1980s single-story brick homes on flat, low-lying ground we routinely find leaks that only show up in a hard rain, traced back to washed-out mortar and flat crowns, so we cut new counter-flashing into the mortar joint instead of relying on a bead of sealant.
Most flashing leaks we repair in Leon Valley 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 Bexar County summer, working the fasteners loose until water runs behind the flashing and down into the ceiling below.
Flashing work in Leon Valley is a one-day job on most homes around Leon Valley, Bandera Road, Evers Road and Huebner, weather permitting.
