Chimney Flashing Repair in Knoxville, TN
Most chimney leaks in Knoxville are not shingle problems. They are flashing failures — and most contractors patch them with caulk instead of fixing the system correctly.
If your chimney has leaked more than once, it's because the flashing was never properly rebuilt. We fix the actual cause — step flashing, counter flashing, and full integration with siding and shingles — so the leak doesn't come back.

From a customer who builds houses for a living:
★★★★★
Mi Home Siding did a great job. Mel was very profrssional and was on time. He replaced sidng on my chimney and flashed the top. I would highly recommed them. As a previous home builder, Mel's craftmansship was surperb. I will call them again for future work.

Why Chimneys Are a Common Source of Roof Leaks
Chimneys are where shingles, brick, and metal flashing all meet. When any part of that connection fails, water gets in — and keeps getting in until the system is rebuilt correctly.
These are installation failures, not material failures. See how we approach roof leak detection and repair in Knoxville.
Signs Your Chimney Flashing Has Failed
Water stains on the ceiling near the fireplace. Moisture in the attic after rain. A leak that was repaired before but came back. Drywall damage that keeps spreading.
If it has happened more than once, the flashing system was never repaired correctly. Our roofing contractor in Knoxville inspects the full system before touching anything.
Why You Should Fix Chimney Leaks Quickly
Ignoring a chimney leak can lead to serious damage:
Water spreads quickly once it enters your home.
01
mold growth
02
damaged insulation
03
ceiling collapse
04
wood rot
05
higher repair costs
Common Chimney Flashing Problems We Fix
Improper step flashing — installed flat instead of layered with shingles, so water runs directly under it.
Missing counter flashing — sitting on top of the chimney instead of embedded into it. Lifts in wind, gaps in rain.
No flashing behind the chimney — the most overlooked point, where water pools and enters from the back.
Caulk used instead of a proper system — holds one season, cracks the next.
Flashing not integrated with siding — water trapped in the wall cavity. Also related: roof flashing repair in Knoxville and missing flashing repair.
Our Chimney Flashing Repair Process
We do not patch. We inspect, remove the failed system, and rebuild correctly.
Step 1 — Full inspection of the chimney, surrounding shingles, and attic below.
Step 2 — Removal of incorrect flashing and any caulk-only repairs.
Step 3 — Installation of proper step flashing, layered correctly with shingles.
Step 4 — Counter flashing embedded into the chimney for long-term weatherproofing.
Step 5 — Integration with siding and back-chimney flashing where needed.
Step 6 — Final inspection and written documentation of all work completed.

Why Caulk Is Not a Fix
A caulk-only repair may temporarily slow a leak, but it does not replace a properly installed metal flashing system.
Proper chimney flashing uses metal that lasts as long as the roof when installed correctly. If the original installation was the problem, see bad roof installation repair in Knoxville.
Structural Integrity and Hidden Damage Policy
- 01If we find rotted decking, damaged framing, or moisture damage during the repair — we stop. We photograph it, explain what we found, and issue a written Change Order before continuing. Sealing is not a substitute for the repair, so what is underneath gets documented first.
- 02If the damage is extensive, we explain whether roof repair or full roof replacement is the right call.
Why Homeowners Choose Us
We have repaired chimneys on new roofs that were still leaking because the original contractor skipped the flashing system entirely. We have rebuilt systems on homes where previous contractors used caulk and called it fixed.

What a Chimney Flashing Repair Includes, and What It Is Worth
A chimney is the most common place we are called to after someone else has already tried to fix it. What separates a repair that lasts from one that does not is whether the counter flashing is actually let into the masonry rather than sealed against it.
What the written proposal spells out. Not a single square-foot number. We name the components being replaced, the area being opened, the materials by name, what happens if the cause turns out to sit somewhere other than where the symptom appeared, and the schedule. Photographs of what we found go with it, so the scope and the evidence arrive together.
How long it takes. Most of our roofing projects run approximately one to two working days, and a focused repair normally sits at the shorter end of that. It is a typical range, not a promise about your roof: size and pitch, access, how many layers are involved, the material, what the decking looks like once it is open, the weather window and anything hidden we find can all move it. The schedule goes in the written proposal.
What the warranty covers on work like this. Our workmanship warranty runs one year on a repair and five years on a replacement. A repair also cannot carry a manufacturer system warranty: those cover a complete installed system, not a section of one. Anyone offering decades of warranty on a single repair is describing something the manufacturer documents do not support.

Frequently Asked Questions – 🔻 FAQs
Why does my roof leak around the chimney?
Most chimney leaks come from failed or missing flashing — not the shingles. When step flashing or counter flashing is wrong or missing, water gets in every time it rains. See our full roof leak detection page for more.
Why does it keep coming back after being repaired?
Because most repairs use caulk instead of rebuilding the flashing system. Caulk fails within one to two seasons. The only permanent fix is correct metal flashing installation.
What is the difference between step flashing and counter flashing?
Step flashing layers with the shingles along the chimney sides to redirect water. Counter flashing embeds into the chimney and caps the step flashing. Both are required for a watertight system.
Can chimney flashing be repaired without replacing the entire roof?
Yes. In most cases the flashing can be rebuilt without touching the rest of the roof. If you are unsure, see roof repair vs replacement in Knoxville.
How long does chimney flashing repair take?
Most repairs are completed in one day.
Is the inspection free?
Yes for standard cases. Complex inspections are covered under our $350 Technical Assessment — credited back if you move forward.
