If your roof is leaking around your chimney

The problem is almost always the flashing.

This is one of the most common failure points we see across Nashville homes. Water runs down your roof, hits the chimney, and if that area is not sealed correctly, it works its way inside.

At Mr. GoodRoof, we specialize in chimney flashing replacement to properly seal this area and stop leaks at the source.

Why Chimney Flashing Is One of the Most Important Parts of Your Roof

Your chimney creates a break in the roofing system. That means water is constantly hitting a vertical surface and trying to find its way in.

Shingles alone cannot protect this area. A proper flashing system is required to:

  • Direct water around the chimney
  • Prevent pooling and buildup
  • Seal transitions between roof and structure

If this system fails, leaks are almost guaranteed.

Why Chimney Flashing Fails

Chimney flashing on a roof in nashville tn

From what we see in the field, most chimney flashing problems come down to how it was originally installed.

Common causes include:

  • Reusing old flashing during a roof replacement
  • Improper step flashing installation
  • Missing or poorly installed counter flashing
  • No cricket installed on larger chimneys
  • Sealant used instead of proper metal flashing

We constantly see situations where flashing was reused just to save cost, and that ends up costing the homeowner much more later.

Signs You Need Chimney Flashing Replacement

  • Leaks near the chimney during rain
  • Water stains on ceilings or walls
  • Cracked or deteriorating seal around the chimney
  • Previous repairs that did not fix the issue

These problems rarely fix themselves and typically get worse over time.

Repair vs Replacement – What Do You Actually Need?

In some cases, minor flashing issues can be repaired.

However, if the flashing was installed incorrectly or is failing across multiple points, replacement is the only way to fix the issue long-term.

We will walk you through exactly what is happening so you can make the right decision without guessing.

How We Diagnose Chimney Leaks

We do not assume the problem. We find it.

Our team gets on the roof and inspects the chimney from every angle, including:

  • Front apron flashing
  • Step flashing along the sides
  • Counter flashing attached to the chimney
  • Back side where water tends to collect

From our experience, leaks often show up in one place but originate somewhere else. That is why a full inspection matters.

Our Chimney Flashing Replacement Process

  • Remove all existing flashing (no reuse)
  • Inspect decking and surrounding materials
  • Install new step flashing along sides
  • Install apron flashing at the base
  • Install counter flashing for full protection
  • Add cricket if needed to redirect water
  • Integrate with shingles and leak barrier

This creates a complete system that directs water away instead of allowing it to sit and penetrate.

Why Other Chimney Repairs Fail

We are often called out after another contractor has “fixed” the problem.

Most of the time, the issue comes down to shortcuts like:

  • Using caulk instead of proper flashing
  • Reusing old materials
  • Not addressing water flow behind the chimney
  • Skipping critical components like step flashing

These are temporary fixes, not long-term solutions.

Frequently Asked Questions

Replacement becomes the right call when **multiple components have failed** or the original installation was wrong from the start. Specific red flags include rust or pinholes through the metal, counter-flashing pulled loose from crumbling mortar joints, missing or absent step flashing on the chimney’s sides, and recurring leaks that have already been repaired once or twice. If the previous installer skipped the cricket on a wide chimney, full replacement is also the opportunity to add one. A free Mr. GoodRoof inspection will tell you whether targeted repair will hold or whether rebuilding the entire system is the only fix that lasts.
Yes — and in most cases it should be. If the surrounding shingles are still in good condition, **chimney flashing can be replaced as a standalone job** without tearing off the roof. Our crew lifts the lower courses of shingles around the chimney, removes all four components of the existing flashing system (apron, step, counter-flashing, and any cricket if present), addresses any decking damage, then installs new flashing with proper integration before re-setting the shingles. The result is a fully rebuilt chimney seal without the cost or disruption of a full roof tear-off.
A real replacement is a system rebuild — not a metal swap. Our process: **remove all existing flashing** (no reuse), inspect the underlying decking and chimney masonry for hidden damage, install fresh **step flashing** along both sides woven between shingle courses, install new **apron flashing** across the front, install new **counter-flashing** properly seated into the chimney’s mortar joints (cutting fresh reglets if needed), install or rebuild a **cricket** behind the chimney if width warrants it, and integrate everything with the surrounding shingles and ice/water shield. Most replacements are completed in a single day.
Chimney flashing has a slightly different material calculus than other roof flashing because the **counter-flashing layer interfaces with masonry**. **Lead** is the traditional premium choice — it’s malleable enough to form perfectly into mortar joints, lasts 50+ years, and is often specified for historic Nashville homes. **Copper** is comparable in lifespan, develops a beautiful patina, and is excellent for high-end chimneys. **Aluminum and galvanized steel** are budget-friendly and work well for standard chimneys when properly installed. Mr. GoodRoof can install any of the four; we’ll recommend the right material based on chimney type, home architecture, and budget.
In almost every case, **yes**. New flashing is one of the smallest line items on a roof replacement quote and one of the biggest determinants of whether the new roof will leak. Old chimney flashing has been bent into the shape of the previous shingle profile, often has corroded counter-flashing pulled out of degraded mortar, and rarely seats correctly against new courses. Mr. GoodRoof always installs fresh chimney flashing with every full roof replacement. If a contractor’s roof replacement quote includes language like “reuse existing flashing,” that’s a red flag worth questioning before signing.
If the mortar joints are already failing, **yes** — and there’s a strong practical reason to do both at once. Counter-flashing is embedded into the chimney’s mortar joints (called reglets), so any new counter-flashing is only as durable as the masonry it sits in. If the mortar is crumbling, new flashing has nothing solid to anchor into and will fail prematurely. Mr. GoodRoof inspects mortar condition during every chimney flashing assessment and will coordinate the repointing alongside the flashing replacement so the entire system is rebuilt together — not patched twice in two years.
When properly installed with sound mortar joints, new chimney flashing lasts **as long as — or longer than — the roof itself**. A standard galvanized or aluminum installation typically lasts 20 to 30 years, copper or lead 50+ years, and the underlying counter-flashing seal can outlive the surrounding shingles entirely if the masonry holds up. The variable is rarely the metal; it’s the **quality of the installation** and the integrity of the chimney’s mortar. That’s why we always assess masonry condition during replacement and why every job comes with a written workmanship warranty.
It depends on the cause of the failure. If your chimney flashing was damaged by a covered peril — a windstorm, a hail event, lightning strike, or a fallen tree limb hitting the chimney — most Tennessee homeowner’s policies will cover replacement, often net of your deductible. Failures from age, wear, deteriorated mortar, or previous improper installation are classified as maintenance and are generally not covered. Mr. GoodRoof offers full insurance claims assistance, including damage documentation, photo evidence, and meeting your adjuster on-site, which often determines whether a borderline chimney claim is approved or denied.
