Roof Flashing Repair in Augusta, GA

If you have a leak that other contractors haven't been able to solve, or one that keeps coming back after repeated caulking attempts, there's a strong chance flashing is the real issue. Flashing failure accounts for a disproportionate share of the roof leaks we see across Augusta — it's the most likely culprit at any point where your roof meets a vertical element: a chimney, a dormer wall, a lower porch roof meeting a two-story wall, around skylights. When flashing fails, it looks like a general roof problem. Apply caulk over it and it appears fixed for a season or two before the water finds its way back through the same gap.

Georgia code requires sheet metal flashing and counterflashing at least 15 inches wide at all chimneys, walls, and roof intersections. On many older Augusta homes — particularly in Summerville, Highland Park, and the Walton Way corridor — the original installation didn't meet that standard, or the flashing that was installed has reached the end of its effective life after decades of Augusta's thermal cycling.

A Real Job from Summerville — Augusta

A 3,200 sq ft craftsman in the Summerville neighborhood, built in the 1930s with multiple additions over the decades — a rear sunroom added in the 1970s and a second-story bedroom suite added in the early 2000s. Each addition created new roof-to-wall transitions.

Water appearing along the interior wall where the sunroom met the original house structure. It had been an intermittent problem for five years. Two different contractors had applied caulk at the roof-to-wall junction on the sunroom side. Each fix held for one rainy season before the staining returned.

When we pulled back the shingles on the sunroom's shed roof at the wall transition, we found the 1970s-era installation had used a single piece of bent aluminum with roofing cement — no step flashing, no counter flashing embedded in the brick. This was common for the era but doesn't meet current Georgia code requirements for 15-inch-wide flashing at wall intersections. The caulk repairs had been applied over the failed original system, adding layers that trapped moisture against the wall rather than diverting it.

Removed the old single-piece flashing entirely. Installed proper step flashing woven with the shingles on the shed roof surface, cut reglets into the brick mortar joints above, and installed counter flashing embedded in those reglets that laps over the step flashing below. Two-layer protection that meets current code and accommodates the thermal movement that Augusta's temperature swings demand.

The homeowner went through two full years — including Augusta's wettest fall season in recent memory — with zero recurrence. That's the difference between a code-compliant flashing system and caulk over a failed one.

Why Flashing Keeps Failing When Done Wrong

Augusta's temperature range creates significant thermal cycling. January lows near freezing followed by July highs above 100 degrees means metal flashing has to expand and contract constantly. A single-piece caulked flashing can't handle that movement — the sealant cracks and separates within a few seasons. Proper step-and-counter flashing systems are designed with independent movement in mind, which is why they don't fail the same way.

The homes most likely to have flashing problems are those built before the 1990s in Augusta's established neighborhoods — Summerville, National Hills, Highland Park, Forest Hills, the Downtown district — where construction practices varied widely and crews weren't always held to today's code standards. If your home has had repeated "caulk repairs" at the same junction, the fix isn't more caulk — it's proper flashing installed to Georgia code.
