Claim SpotThe joint where the chimney meets the roof is the most common leak point on Alamo Heights homes. Chimney Operations replaces failed step and counter-flashing properly — cut into the mortar joint and sealed, not caulked over. That matters most with clay tile and slate roofs where careless foot traffic causes its own damage.

Flashing is where Alamo Heights chimneys leak most, and locally that means clay tile and slate roofs where careless foot traffic causes its own damage. Add in decades of weathering on masonry that was never sealed or maintained, and any gap at the roof line turns into an interior stain. In 1920s through 1950s historic homes with original masonry chimneys we routinely find earlier repairs done with hard cement mortar that trapped water and spalled the original brick, so we cut new counter-flashing into the mortar joint instead of relying on a bead of sealant.
Most flashing leaks we repair in Alamo Heights 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.

Yes. Between clay tile and slate roofs where careless foot traffic causes its own damage, plus decades of weathering on masonry that was never sealed or maintained, the joint between chimney and roof takes the most abuse of anywhere on the house. We find earlier repairs done with hard cement mortar that trapped water and spalled the original brick regularly across Alamo Heights, Olmos Park, Terrell Hills and Broadway.
