A water stain on the ceiling near the fireplace. Discoloration on the wall behind the chimney. A musty smell in the room that gets worse after rain. These are the things homeowners call us about, and we catch this situation all the time. The chimney itself isn’t usually leaking. The flashing, the metal system that seals the joint where the chimney meets the roof, has failed. It’s one of the most consistently misdiagnosed leak sources in residential roofing, and it’s one of the most reliably fixable when approached correctly.
When You Need Chimney Flashing Repair
Chimney flashing fails in predictable ways. Step flashing along the sides of the chimney lifts or separates from the shingles. Counter flashing pulls away from the mortar joints where it’s embedded in the chimney face. Sealant dries out and cracks with Georgia’s temperature cycles. Metal corrodes or was sized incorrectly at the original installation. In some cases, a roofer who replaced the shingles left the old flashing in place without re-integrating it properly, and the system that appeared fine after the job starts leaking at the first sustained rain.
Wide chimneys sometimes need a cricket, a small peaked structure installed behind the chimney to divert water around it rather than letting it pool and sit against the flashing. When a chimney is positioned in a roof valley or sits in a spot where debris collects, a missing or damaged cricket is often part of why the flashing keeps failing. We assess the full picture, not just the visible seam.
Our Chimney Flashing Repair Process
We begin by inspecting the full chimney flashing system: the base flashing, step flashing woven into the shingles along the sides, counter flashing embedded in or attached to the chimney masonry, and the condition of any sealant at the joints. We also check the surrounding shingles, the valley if applicable, and the attic below for signs of how long water has been entering and where it’s been traveling.
From there, we repair or replace the components that have failed. That may mean re-bedding counter flashing into the mortar joints, re-integrating step flashing with the shingle courses, or replacing the full flashing system when the metal has corroded or was improperly installed from the start. We don’t cover failed flashing with sealant alone and call it done. Surface-applied sealant over improperly integrated flashing is a short-term fix that creates repeat service calls.
Chimney Flashing Repair Cost in Acworth
Cost depends on the scope of the flashing failure, whether the full system needs replacing or targeted sections can be repaired, and whether any shingle work or decking repair is required as part of the fix. We provide free written estimates after inspection. No surprises after the work starts.

Frequently Asked Questions
What is chimney flashing and why does it fail?
Chimney flashing is the metal system that seals the junction between the chimney and the roof surface. It consists of step flashing woven into the shingles along the sides, counter flashing embedded in or fastened to the chimney face, and base flashing at the bottom. It fails due to metal corrosion over time, sealant drying out and cracking with temperature cycles, improper original installation, and normal structural movement as the home settles. Georgia’s heat, humidity, and freeze-thaw cycles accelerate all of these failure modes.
How can I tell if my chimney leak is from flashing versus the chimney structure itself?
Flashing failures typically produce leaks that appear immediately adjacent to the chimney, on the ceiling or wall at the chimney’s base, or in the attic directly below the chimney-roof junction. Structural chimney issues, such as cracked mortar or a failed chimney crown, tend to produce water inside the flue or at the top of the chimney interior. In practice, we inspect both the flashing system and the visible chimney structure during a leak diagnosis, because the two can appear similar from inside the home.
Is it possible to repair chimney flashing without replacing it entirely?
Yes, in some cases. If the metal is in reasonable condition but the sealant has failed or counter flashing has pulled away from the mortar joint at one location, a targeted repair can be the right call. When the metal is corroded, was improperly sized at installation, or the step flashing wasn’t properly woven into the shingle courses, full replacement of the flashing system is the more reliable repair. We assess each situation specifically and recommend what will actually hold.
My roof was replaced recently and now the chimney is leaking. Is that related?
Very likely. Chimney flashing is one of the most commonly skipped or improperly handled elements during a roof replacement. Some contractors leave old flashing in place without re-integrating it properly with the new shingles and underlayment, which creates a leak pathway that didn’t exist before the replacement. If you have a new roof and a new chimney leak, the flashing system is the first place to look.
Does a chimney need a cricket and what is it?
A chimney cricket is a small peaked structure built on the uphill side of a chimney to divert water and debris around it rather than allowing it to collect against the flashing. Wider chimneys positioned where water naturally flows toward them often require a cricket to prevent chronic flashing failures. Georgia building code addresses chimney cricket requirements for wider chimneys. If your chimney has a history of repeated flashing problems, the absence of a cricket may be contributing to the issue, and we assess for this during inspection.
