Flashing Repair you can actually trust
Roofers caulk flashing; masons cut it in. We replace step flashing shingle by shingle and set new counter-flashing into a saw-cut reglet in the mortar joint, wedged and sealed with polyurethane — a detail that outlives the shingles above it.
Every Oakville job is quoted in writing before any work begins, and backed by a 5-year workmanship warranty.
