Who Fixes Chimney Flashing? Which Pro to Hire for the Job

This article was created using automation technology and thoroughly fact-checked and edited by HomeAdvisor Editor Ryan Noonan.

If you are asking who fixes chimney flashing, start with a roofing contractor. Flashing is part of your roof’s waterproofing, so a roofer inspects, repairs, or replaces it to keep the junction watertight. If the issue stems from chimney masonry, a chimney repair specialist addresses brick and mortar problems before flashing is reinstalled.

Benefits of Hiring a Roofing Contractor to Repair Chimney Flashing

Because flashing is integral to your roof, roofers are best equipped to fix it without compromising the surrounding materials. They understand how flashing overlaps and seals with shingles and underlayment, use the right tools, and work safely at height. Roofers also spot related roof issues and address moisture that can lead to mold, extending your roof’s life.

Here are other ways the hiring a roofing contractor for chimney flashing repair benefits your project:

• Inspect the roof to find leaks, rust, cracks, or gaps.

• Integrate flashing with shingles and underlayment so water sheds cleanly.

• Use metalworking tools to cut, bend, and fit flashing.

• Identify non-flashing roof issues uncovered during inspection and address them.

• Manage moisture buildup that leads to mold and further deterioration.

• Deliver long-term, watertight results rather than short-lived patching.

• Work with proper safety practices and equipment to prevent falls.

If you’re dealing with persistent leaks or complex roof–chimney junction issues, you might want to consider a roof repair pro near you to ensure the job is done safely and correctly.

Can I Hire a Chimney Repair Contractor?

Hire a chimney repair specialist when the problem ties back to the chimney’s structure. These pros repair brick, mortar, and stone, tackling cracked masonry or loose joints that undermine flashing performance. The right sequence matters: fix structural damage first, then reinstall flashing for a lasting seal. If the root cause is roof-related rather than masonry, choose a roofer.

How Do Pros Fix Chimney Flashing?

Pros follow a clear process to ensure a watertight result:

1. Inspect existing flashing for rust, cracks, failed sealant, and gaps where water enters.

2. Remove old flashing and any surrounding caulk or roofing cement to expose clean surfaces.

3. Cut and shape new metal flashing—aluminum, copper, or galvanized steel—to fit snugly.

4. Install base and counterflashing in layered pieces that tie into shingles and mortar joints, overlapping to shed water.

5. Apply roofing cement and appropriate caulk at seams to secure and seal the system.

6. Verify a tight, continuous seal and proper water flow away from the chimney.

How Much Does Chimney Flashing Repair Cost?

Repairing chimney flashing costs $150 to $500. These costs can reach $1,000 or more in cases where flashing damage is more widespread across your roof. Roofing contractors charge between $45 and $75 per hour for repairs, often with a minimum call-out fee.
