MI Homesiding & Roofing

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.
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 Knoxvilleinspects the full system before touching anything.
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
aulk expands and contracts with Tennessee heat cycles. It cracks within one to two seasons. Every contractor who patched your chimney with caulk bought you one winter — not a solution.
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
If 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. We never seal over hidden damage.
If the damage is extensive, we explain whether roof repair or full roof replacement is the right call.
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.

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.
