Chimney Flashing Repair in Shavano Park, TX

Flashing Failures On Shavano Park Roofs — Multi-Flue Custom Stacks

Flashing is where Shavano Park chimneys leak most, and locally that means complex rooflines with wide chimneys that need crickets behind them. Add in water pooling behind wide stacks where the roof has no diverter, and any gap at the roof line turns into an interior stain. In large custom estates with two or three fireplaces venting through one stack we routinely find one-size caps that never fit these stacks, so we fabricate multi-flue covers to measure, so we cut new counter-flashing into the mortar joint instead of relying on a bead of sealant.

Most flashing leaks we repair in Shavano Park 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 Shavano Park is a one-day job on most homes around Shavano Park, Bentley Manor, Huntington and NW Military Highway, weather permitting.
