If your roof is leaking where it meets a chimney or wall

The problem is often the apron flashing.

This is one of the most common leak points we see across Nashville homes, especially after heavy rain or storms. When this area is not sealed correctly, water is pushed directly into your roofing system.

At Mr. GoodRoof, we provide apron flashing repair in Nashville to stop leaks at the source and restore proper water flow.

What Apron Flashing Does

Apron flashing is installed at the base of vertical structures like chimneys and walls on the downhill side.

Its job is to:

  • Direct water away from the base of the structure
  • Prevent water from getting behind shingles
  • Create a smooth path for water to flow down the roof

When this component fails, water has a direct path into your home.

Why Apron Flashing Problems Are So Common

From what we see in the field, apron flashing issues usually come from shortcuts during installation or temporary repairs.

Common causes include:

  • Cracked or deteriorating sealant
  • Improper overlap with shingles
  • Damage from storms or shifting materials
  • Previous repairs that did not address the full system

Many of these problems come from trying to patch the issue instead of fixing it properly.

Signs You Need Apron Flashing Repair

  • Leaks at the base of a chimney or wall
  • Water stains near these areas inside your home
  • Issues that show up during heavy rain
  • Previous flashing repairs that did not last

If you are seeing these signs, the issue should be inspected before it worsens.

Why Many Apron Flashing Repairs Fail

We are often called out after homeowners have already tried to fix the problem.

Most of the time, the issue comes down to temporary fixes such as:

  • Using caulk instead of replacing flashing
  • Repairing shingles without addressing flashing
  • Ignoring how water is flowing into the area

From our experience, if the flashing is not repaired correctly, the leak will come back.

How We Diagnose Apron Flashing Issues

We do not just look at the flashing itself. We evaluate how water is moving across your roof.

Our inspection includes:

  • Checking apron flashing condition and placement
  • Inspecting surrounding flashing systems
  • Evaluating water flow toward the structure
  • Identifying areas where water may be pooling

This allows us to find the real source of the problem.

Repair vs Replacement – What Do You Actually Need?

If the damage is minor and localized, repair is often the best option.

If the flashing is failing across multiple areas or was installed incorrectly, replacement may be recommended.

We will walk you through exactly what we are seeing so you can make the right decision.

Frequently Asked Questions

**Apron flashing** is a piece of metal flashing installed at the base of a vertical surface where it meets a sloped roof — most commonly the downhill side of a chimney, dormer, or sidewall. Its job is to direct rainwater away from that vertical structure and onto the shingles below, where it can flow safely off the roof. When apron flashing is missing, damaged, or installed incorrectly, water has a direct path behind the shingles and into your roof deck, walls, and ceiling. It’s a small component with an outsized impact on whether your roof actually keeps water out.

Leaks at the base of a chimney, dormer, or sidewall are almost always a **flashing failure** — not a shingle problem. The most common culprits we see in Nashville are deteriorated or cracked sealant, apron flashing that was never properly overlapped with the shingles, storm-loosened metal, and previous DIY repairs that addressed the symptom rather than the source. Because chimneys and walls take the full force of wind-driven rain during Middle Tennessee storms, even small flashing flaws turn into active leaks quickly. A proper inspection identifies the real failure point so the leak doesn’t return.

Often, yes. If the flashing is structurally sound but the sealant has failed, the overlap was sloppy, or one section was damaged in a storm, a targeted **repair** can restore performance and stop the leak for years. If the metal itself is corroded, bent, or was installed incorrectly across multiple transition points, full replacement is the better long-term call. Mr. GoodRoof inspects the surrounding flashing system — not just the obvious leak point — and walks you through exactly what we’re seeing so you can make the right decision for your home.

Caulking a flashing leak is one of the most common DIY mistakes we get called out to fix. **Caulk is a temporary band-aid, not a flashing repair.** It hides the symptom for a few months, then cracks under UV exposure and freeze-thaw cycles, and the leak returns — often worse than before because moisture has been trapped against the wood deck the whole time. Proper apron flashing repair addresses the root cause: lifting and re-bedding the metal, correcting overlap with the shingles, and restoring the water path. That’s what makes a repair last.

Most apron flashing repairs are completed in a **single visit, typically two to four hours**, depending on access and how much surrounding work is needed. If the surrounding shingles, counter-flashing, or chimney mortar also need attention, the job can extend into a half- or full-day project. We’ll quote everything upfront based on what the inspection reveals — no surprise add-ons after we start. In urgent leak situations, same-day service is often available across Nashville and Middle Tennessee.

When apron flashing is repaired correctly — meaning the metal is properly seated, overlapped with the shingles, and sealed at the right transition points — a quality repair can last **the remaining life of your roof**, often 10 to 20 years or more. The repairs that fail prematurely are almost always the ones that relied on caulk or skipped the surrounding flashing system. Mr. GoodRoof’s apron flashing repairs are backed by a workmanship warranty, and we replace flashing rather than reusing it whenever the metal shows any sign of fatigue.

Both are types of roof flashing, but they handle different parts of the same problem. **Apron flashing** is a single, continuous piece of metal that runs across the **downhill side** of a chimney, dormer, or wall — it directs water away and onto the shingles below. **Step flashing** is a series of overlapping rectangular pieces installed along the **sides** of those same vertical structures, layered between each row of shingles. A complete chimney flashing system uses both — plus counter-flashing on top — and a leak often means one of the three has failed.

It depends on the cause. If your apron flashing was damaged by a covered peril — such as a windstorm, hail event, or fallen tree — most Tennessee homeowner’s policies will cover the repair, often net of your deductible. If the failure is due to age, wear, or a previous improper installation, it falls under maintenance and is generally **not** covered. Mr. GoodRoof offers full insurance claims assistance, including documentation, photo evidence, and meeting your adjuster on-site, which often makes the difference between a denied claim and an approved one.
