Professional Chimney Flashing Repair in Franklin Park, IL
Stop Leaks at the Source
Leaky chimney flashing is one of the most common causes of roof and ceiling water damage in Franklin Park, IL. When flashing fails at the roofline joint, water finds a direct path into your home. Often, the damage is hidden until stains appear on your ceiling — by then, water has been entering for one or more seasons.
This page covers chimney flashing inspection, reseal, and full replacement where your chimney meets the roof. We schedule most inspection visits within one to two weeks. As a licensed masonry contractor, we find where the leak starts and fix it before it reaches your walls, roof deck, or insulation.

What Chimney Flashing Repair in Franklin Park, IL Involves
Chimney flashing repair means resealing or replacing the metal that seals the joint between your chimney and roof. A masonry contractor in Franklin Park inspects the full flashing system and finds where metal has lifted or corroded. Then we reseal or replace it to stop water from entering.
Core steps:
- Inspect base, counter, and step flashing at every edge
- Remove failed caulk and mortar at the flashing joint
- Replace corroded or improperly installed flashing sections where needed
Signs Your Chimney Flashing in Franklin Park Is Leaking or Failing
Chimney flashing failures are common in Franklin Park homes. Many homeowners don't spot the problem until water stains show up on a ceiling near the fireplace. By then, water has likely been entering the roofline joint for one or more seasons.
Watch for these signs:
- Water stains on ceilings or walls near the chimney
- Visible rust on the flashing metal at the roofline
- Caulk or mortar that is cracked, missing, or pulling away from the chimney
- Lifted or bent flashing edges visible from the ground
- Musty smell near the fireplace — moisture has built up inside the wall cavity
We inspect the full flashing system and tell you whether it needs a reseal or a full replacement.
What Chimney Flashing Repair Includes — From Reseal to Full Replacement
Not every flashing job is the same. Some Franklin Park homes need a simple reseal of the existing flashing. Others have corroded, improperly installed, or fully separated flashing that needs to come out and be replaced.
A flashing repair or replacement covers:
- Base flashing — the metal that wraps the chimney base at the roof surface
- Counter flashing — the upper layer embedded into the mortar joints on the chimney face
- Step flashing — individual pieces that run alongside the chimney up the roof slope
- Sealant and mortar at all edges to close any remaining gaps
We match the flashing material to your existing roof and chimney type. The job is finished before we leave.
Why Franklin Park Freeze-Thaw Cycles Pull Flashing Away From Your Chimney
Chimney flashing is built to flex as your roof and chimney expand and contract. But in Franklin Park, freeze-thaw cycles run hard from October through March. That constant movement breaks sealant bonds and loosens the mortar that holds counter flashing in place.
Homes near the Mannheim Road corridor face wind-driven rain that hits lifted flashing edges directly. Once a gap opens, each rain event pushes more water into the roofline joint. A small separation that forms in fall can become an active interior leak by February.

Frequently Asked Questions
Water stains on ceilings or walls near your chimney are the most common sign that flashing has failed. We inspect the full roofline joint to confirm the source before any work begins.
Resealing works when the flashing metal is still in good shape but the sealant or mortar has failed. If the metal is corroded, lifted, or was installed incorrectly, replacement is the right call. We make that determination during the inspection.
Minor reseal work typically does not require a permit in Franklin Park. Full flashing replacement may require one depending on the scope of work. We confirm permit requirements before the job starts.
Most chimney flashing repairs in Franklin Park finish in a single day. Full replacement on a larger chimney may take two days.
We use metal flashing — typically aluminum or galvanized steel — matched to your roofline and chimney type. The material is selected to handle Illinois freeze-thaw conditions year after year.
Spring and early fall are the best times for flashing repair in Franklin Park. We can also work through most of winter when temperatures stay above freezing and conditions are safe for roof access.
