Roof Flashing Repair in Big Creek, GA
Last September, we got a call from a homeowner on Kimball Bridge Road near the Halcyon development. Her house was built in 2003, and she’d noticed water stains appearing on her master bedroom ceiling every time it rained. She’d already had two other contractors out. One said she needed a full roof replacement. The other couldn’t find the problem at all.
We did what we always do—climbed up there and actually looked. The shingles were in solid shape. The problem? The step flashing along her dormer had pulled away from the wall. Twenty years of Georgia heat cycles had caused the original galvanized flashing to warp just enough to create a gap. Water was running behind the siding and into her ceiling.
Total repair time: three hours. Total cost: a fraction of what that unnecessary roof replacement would have run. That’s why proper diagnosis matters.
Why Flashing Fails in Big Creek Homes
Big Creek sits in an interesting spot along the GA-400 corridor. Most homes in the 30004 and 30005 zip codes were built between the mid-1990s and 2010s, which means we’re seeing a lot of roofs hit that 15-25 year mark where flashing problems start showing up.
Here’s what we commonly find during roof inspections in this area:
- Chimney flashing separation – The caulk seal between counter flashing and masonry breaks down, and water finds its way in
- Valley flashing corrosion – Homes with complex rooflines (which describes most of Big Creek) have multiple valleys where water concentrates
- Pipe boot deterioration – The rubber seals around plumbing vents crack after 10-15 years of UV exposure
- Skylight flashing failure – Several neighborhoods near Big Creek Greenway have homes with multiple skylights that weren’t flashed to current standards
Georgia building code requires flashing at all roof-to-wall intersections, around penetrations, and in valleys. But code compliance and quality installation are two different things. We’ve pulled up flashing on 2008-era homes that was barely tacked in place.
The Flashing Repair Process
When you call us about a potential flashing issue, we start with a thorough roof inspection. Not a quick glance from the driveway—we get up there with cameras, moisture meters, and enough experience to know where water likes to hide.
If flashing is the culprit, repair typically involves:
- Carefully removing shingles around the affected area
- Pulling out the failed flashing without damaging surrounding materials
- Installing new flashing with proper overlap and sealant
- Reinstalling shingles with correct nail placement
- Testing the repair with water to confirm the leak is resolved
For chimney flashing repair, we often recommend upgrading to a two-piece counter flashing system. It costs a bit more upfront but holds up significantly longer than the single-piece installations common in production-built homes.
We also check adjacent areas while we’re up there. If your step flashing has failed, there’s a decent chance your pipe boots are nearing end of life too. Better to address everything at once than pay for two service calls.

Don’t Let Small Leaks Become Big Problems
Here’s the thing about flashing leaks: they start small. A little discoloration on the ceiling. Maybe some peeling paint around a window. Easy to ignore. But water doesn’t stop. It finds its way into your roof deck, your insulation, your framing. What could have been a $400 repair turns into a $4,000 leak repair with potential mold remediation.
