Chimney repair and removal on Jacksonville roofs
Updated September 2026
A chimney is the biggest hole in most roofs, and in Florida many of them are barely used. When one leaks, the cause is usually the crown, the cap or the flashing around it. We find which one and fix it, or take an unused chimney down below the roofline and close the roof over it.
- Calls answered 24/7
- Crowns, caps and flashing
- Removal with a matched roof patch
Chimney repair in Jacksonville, FL covers cracked crowns and missing or rusted caps that let rain into the flue, leaks at the flashing where the chimney meets the roof, and removal of unused chimneys below the roofline with the deck and roof patched to match. Masonry rebuilding beyond the crown is work for a mason, and we coordinate it where it is needed.
What to look for
Signs your chimney needs attention
Stains on the ceiling or wall beside the chimney
Water is getting in at the crown, cap, brick or flashing.
Cracks across the crown
Rain soaks into the chimney from the top.
A missing or rusted cap
Rain and animals can get straight into the flue.
Crumbling mortar or flaking brick
The masonry is taking on water; a mason's job.
A damp or musty smell from the fireplace
Water is coming down the flue.

Three leak paths
How chimneys let water in
Water gets into a chimney in three ways: down the flue when the cap is missing, through a cracked crown on top, and around the base where the flashing meets the roof. The first two are chimney problems that show up as roof leaks; the third is a roofing problem. Stains on the ceiling beside a chimney could be any of the three.
Many Jacksonville chimneys serve fireplaces that are rarely lit, and some serve nothing at all. For those, removing the chimney below the roofline and closing the roof over it ends the leak for good and removes a joint that storms test every season.
Chimney Repair & Removal
Chimney crown and cap repair
The crown is the mortar or concrete slab that caps the top of the chimney, and it cracks with age and heat. Small cracks are sealed with a crown sealer made for masonry; a crown that is crumbling or pitched the wrong way is rebuilt with an overhang so water drips clear of the brick. A stainless cap with a screen goes over the flue to keep rain and animals out.
Brick that is loose or spalling below the crown is flagged for a mason rather than patched over.
Typical market range for chimney and skylight flashing repair, Jacksonville: $1,200 to $2,500 (source). A planning figure, not a quote.
Chimney Repair & Removal
Chimney leak diagnosis
A leak beside a chimney is traced before anything is replaced. We check the cap and crown from the roof, the flashing and cricket at the base, and the chimney's brick for cracks and open mortar joints, then look from the attic for where the water actually runs. A hose test on one part at a time, starting low and working up, separates flashing leaks from masonry leaks.
Flashing problems are repaired as flashing repair; masonry problems go to a mason with our findings.
Chimney Repair & Removal
Chimney removal and roof patch
An unused chimney can be taken down below the roofline, which removes the crown, cap and flashing leak points in one job. The brick is removed down into the attic, the opening is framed to match the rafters, new decking goes in, and the roof covering is woven into the surrounding shingles or panels. Where the chimney continues through the house, the remaining masonry is capped inside the attic.
A chimney that still vents an appliance is never removed; that flue has to be rerouted by the right trade first.
Roofing in Jacksonville
Old chimneys, historic districts and storms
Many of Jacksonville's chimneys sit on older houses, and in the city's three locally designated historic districts, including Riverside Avondale and Springfield, a Certificate of Appropriateness is required for exterior work, which includes rebuilding or removing a visible chimney. Storms test the rest: the National Hurricane Center's report on Irma records hurricane-force gusts and widespread tree damage across northeast Florida, the kind of wind that finds a loose cap or a cracked crown.
Do it yourself?
What you can check, and what needs a roofer or mason
| Task | Homeowner | Roofer or mason |
|---|---|---|
| Spotting a missing cap or cracked crown | From the ground with binoculars | Not needed |
| Checking the attic beside the chimney | Yes, with a flashlight | Tracing the leak path |
| Sealing the crown or replacing the cap | No; it means working at the top of the roof | Roofer |
| Repointing or rebuilding brick | No | Mason, with our findings |
Never cap or close a flue that still vents a furnace, water heater or fireplace in use.
Cost factors
What decides the cost of chimney work
What failed
A cap or crown seal is small; a crown rebuild or new flashing is more.
Chimney height and access
Tall chimneys on steep roofs need more safety setup.
Removal
Taking a chimney below the roofline adds carpentry and roofing.
Masonry
Brick and mortar repairs by a mason are priced separately.

Questions we hear
Chimney questions
Wind-driven rain gets past loose flashing or a missing cap that ordinary rain does not reach.
Yes, on any chimney that stays open. A screened cap keeps out rain and animals.
Yes, below the roofline, with the roof patched to match, as long as the flue no longer vents anything.
We repair crowns, caps and flashing and handle removal. Rebuilding brick is a mason's work, and we coordinate it.
Visible changes need a Certificate of Appropriateness first. See historic home roofing.
