Chimney flashing fails most often where the masonry meets the roof deck on pre-1960 homes common in West Reading and Hyde Park. Temperature swings between hot humid summers and freezing winters loosen step flashing and counter flashing, allowing water to track under shingles and into attics. We use lead or copper step flashing cut to the existing brick courses rather than pre-formed aluminum that cracks against irregular Berks County masonry.
Edge cases include chimneys that lean slightly from age or have been parged multiple times; these require custom cricket fabrication so water sheds away from the high side. In Glenside and near the Berks County Courthouse, slate roofs demand careful removal of individual slates without cracking them during flashing replacement. We never rely on sealant alone because summer UV and winter ice quickly degrade caulk on south-facing slopes.
Code considerations in Reading require flashing to extend at least six inches up the chimney and four inches under the shingles. When we find rotted sheathing from long-term leaks, we replace it before installing new flashing so the repair lasts through the next freeze-thaw cycle. Homeowners near FirstEnergy Stadium often call after heavy summer storms expose flashing that had been leaking slowly all winter.
Technician insight
In Reading, the thing that catches most people out with Chimney Flashing Repair is how the freeze-thaw cycles in Berks County loosen mortar on pre-war brick chimneys around West Reading and Mount Penn, so simply slapping new metal over old joints never lasts.
Hyde Park Chimney Leak After Summer Storms
Water stains appeared on a second-floor ceiling after heavy rain. We found step flashing that had pulled away from the chimney on a 1940s home. The old aluminum had cracked at the bends. We replaced it with copper step flashing woven into the shingles and repointed the counter flashing line. The homeowner reported no further leaks through the next winter.
