Plan My RepairHow We Plan Flashing & Vent Repair In Frederick
Flashing and vent leaks often look small from inside but can move water into insulation, decking, and wall cavities. We inspect the transitions where roofing material meets penetrations and vertical surfaces before recommending the repair.
The most common flashing failure we see on Frederick homes is chimney counterflashing that has been caulked rather than properly replaced. A correct chimney flashing system uses three pieces: base flashing, step flashing interwoven with the shingles, and counter or cap flashing embedded into the mortar joint. Hardened caulk cracks with the freeze-thaw cycle and seasonal movement — proper counterflashing does not.
Pipe boots are the other frequently overlooked failure point. Neoprene rubber pipe boots degrade from UV exposure over 10-15 years. On a 20-year-old roof in Frederick, every boot should be evaluated — a failed boot can drip water down the plumbing vent pipe directly onto the ceiling below.
