Roof Flashing Repair in Atlanta, GA

Flashing is the metal barrier that seals every point where your roof surface meets something vertical — a chimney, a dormer wall, a skylight frame, where a lower roof butts into a wall. Here's the practical reality: flashing failure is responsible for a large share of all roof leaks in Atlanta. Not worn-out shingles across the whole roof — just metal that's lifted, cracked, or separated at one specific transition point.

We've repaired flashing on homes throughout Atlanta, from century-old Craftsman bungalows in Virginia-Highland where original lead flashing finally gave out, to 2000s construction in Smyrna and Marietta where installation corners were cut. Flashing problems are universal regardless of home age — they just show up differently.

What Goes Wrong

Thermal movement. Metal expands in Atlanta summers and contracts in winter. Over years of cycling, sealed joints crack open. The sealant gave up; now water found the gap.

Original installation shortcuts. One-piece caulked flashing where step and counter flashing should have been. Improper overlap. We see this regularly on Atlanta homes built during boom periods when crews were moving fast.

Chimney flashing specifically. The step flashing woven with shingles on the sides, the counter flashing embedded in mortar joints — any of those can fail independently. Chimneys are the most failure-prone flashing location on most roofs.

Dormer and addition intersections. Anywhere an older part of a house meets a newer addition is a high-risk flashing zone. We see a lot of leak problems at these junctions on Atlanta's older renovated homes.

How We Fix It

Sometimes flashing just needs resealing and resecuring. More often — especially if it's been leaking for any length of time — it needs to come out and be replaced correctly. For chimney work, we do it the right way: step flashing woven with the shingles, counter flashing tucked into mortar joints. Two-layer protection — not one piece of metal and a tube of sealant.

Proper flashing repair eliminates the leak permanently. If a previous contractor just added caulk over existing failed flashing, that's a six-month fix at best. We don't do that. For related issues, see our full roof repair services.
