The craft, done properly
CHIMNEY FLASHING & LEAK REPAIR IN ANN ARBOR, MI

Flashing is the metal seal where the chimney passes through the roof, and it is the most leak-prone spot on most Ann Arbor houses. It works in two layers — step flashing woven into the shingle courses, counter-flashing set into the masonry above it — so water sheds outward at every level. In a Michigan winter that seal faces something rain never does: snow that sits, melts slowly against the roof, and backs up under the flashing instead of running off it.

Brown Chimney repairs and replaces flashing, priced by scope and access — every option is on our flashing repair pricing page. We install step, counter, and saddle flashing in aluminium or lead-coated copper only — never plastic, never rubber, both of which go brittle in a Washtenaw County cold snap — sealed with chimney-rated elastomeric caulk. Chimneys wider than 30 inches at the roofline need a cricket by code to divert water and snow around the upslope side, and that is identified during the assessment.

The Work

What flashing repair does for an Ann Arbor home.

The stain on your ceiling is rarely under the hole. Water enters at the flashing, runs along the roof deck or down the outside of the flue, and surfaces wherever gravity and framing let it. That is why the first job is diagnosis, not sealant — sealing the wrong seam is money spent to keep the leak.

Ann Arbor adds a seasonal wrinkle: leaks that only appear during a thaw are usually flashing, because snowmelt backs up under a lifted seam where a summer downpour would run straight past it. Flashing is also only one of several ways water gets in. A crazed crown, a missing cap, and failed mortar all deliver water into the same structure. If the crown is part of the problem, crown repair gets quoted alongside the flashing so both entry points close in one visit rather than one leak-chasing trip after another.

We trace and repair chimney leaks across Washtenaw County and in Brighton and Northville. See the local service list on the Ann Arbor page.

When to book

What are the signs your chimney flashing has failed?

Flashing failure shows up inside the house long before anyone looks at the roof — and in Ann Arbor it often shows up first during a January thaw. These are the signs our crews hear about most.

01

Water stains on the ceiling or wall near the chimney

02

Damp or discoloured framing visible in the attic around the chimney

03

Shingles lifting, curling, or missing where the chimney meets the roof

04

Rusted, bent, or visibly separated metal at the roofline

05

Sealant that has hardened, cracked, or pulled away from the masonry

06

Leaks that appear during a thaw or in driving rain from one direction

‍

If water is showing inside, the entry point needs finding before anything gets sealed. An inspection traces it and gives you a repair quote, and the fee is credited toward repair work booked within 30 days.

What to expect

What happens during a leak repair?

Leak work in Ann Arbor is diagnosed first, quoted second. Most flashing repairs complete in a single visit; jobs needing a cricket or extensive roof work are scoped during the assessment.

01

Leak source diagnosis

Water stains rarely start where they show. We trace the actual entry point — flashing, crown, cap, or masonry — before quoting anything, because sealing the wrong spot solves nothing.

02

Written quote before the roof is opened

You approve the exact price before anything is lifted. Chimneys wider than 30 inches at the roofline need a cricket by code — if yours does, that's identified and priced up front.

03

Old flashing removal

Failed flashing and hardened sealant come off down to sound roof deck. Any pre-existing shingle damage is documented and quoted separately rather than quietly absorbed.

04

New flashing installation

Step, counter, and saddle flashing set in aluminum or lead-coated copper — never plastic, never rubber — and sealed with chimney-rated elastomeric caulk.

05

Roof restored, photos taken

The roof area around the chimney base is restored, the work photographed before and after, and the labor covered by the 1-year workmanship warranty.

Leak path tracer

Where is the water actually getting in?

The stain on your ceiling is rarely under the hole. Water gets in at the flashing, the crown, the cap or a failed mortar joint, then runs along the roof deck or down the flue and shows up wherever gravity takes it. Tell us what you see and when, and we trace the likely entry point and show what the repair involves.

Chimney flashing

Flashing is the metal seal where the chimney passes through the roof, and most chimney leaks start there. Water gets under a lifted or caulk-patched seam, runs along the roof deck, and shows up on the ceiling, often away from the chimney itself.

  • Chimney flashing$300 – $3,500, depending on its condition

    Flashing that is intact but leaking at the seams is cleaned, re-secured and resealed; aging flashing that is still solid can be coated as one piece; rusted or lifted flashing is replaced.

    Most likely
  • Chimney crown$250 – $900 sealing · repair or rebuild measured

    A crown with hairline cracks is sealed with a flexible crown coating. Open cracks need a crown repair (length × width in inches plus $250), and a crown too damaged to repair is rebuilt, priced after measurement.

    Also possible
  • Mortar joints and brick face$40 per sq ft, min. $600

    Worn joints are cleaned out and repacked with mortar matched as closely as possible; deep or badly deteriorated joints are priced on site. Waterproofing is recommended afterward.

    Also possible
  • Leak diagnosis visit: the entry point is found before any repair$150
  • Diagnosis fee credited toward repair work booked within 30 days−$150
  • Likely repair on these answers$300 – $3,500, depending on its condition
  • Leaks that only show in certain weatherMay need a second visit, quoted separately
  • Workmanship warranty1 year on repair labor

The ranking is a guide, not a diagnosis: the entry point is confirmed on site and put in writing. The diagnosis fee is credited toward repair work booked within 30 days. Some leaks only show in certain weather and may need a second visit, quoted separately. Final prices are set on site and confirmed with you before work begins; repairs carry a 1-year workmanship warranty on labor.

Moe (and team) did a great job with our chimney repairs! Moe’s inspection was thorough and he took the time to explain each task in the quote. Scheduling the repairs was easy and after the work was complete, he explained everything they did. Moe also took lots of pictures before and after the work to document, which I appreciated.

FAQs

Common questions about flashing & leak repair in Ann Arbor

1 icon

How is chimney flashing repair priced in Ann Arbor?

By scope, chimney size, and complexity — from resealing seams to full replacement. Chimneys requiring a cricket, or those needing lift access, are identified during the assessment and priced up front — the written quote comes before anything is lifted. Every option and its price is on our flashing repair pricing page.
Faq Number

Why does my chimney only leak when the snow melts?

Because meltwater behaves differently than rain. Snow sits against the roof and works sideways under a lifted flashing seam, where a vertical downpour runs straight past it. Thaw-only leaks are one of the clearest signs that flashing, not masonry, is the entry point.
3 icon

What material should chimney flashing be?

Aluminium or lead-coated copper — Brown Chimney installs nothing else. Plastic and rubber flashing go brittle under Michigan temperature swings and fail years sooner, which is why they are excluded regardless of cost. Joints are sealed with chimney-rated elastomeric caulk.
4 icon

What is a chimney cricket and do I need one?

A cricket is a small peaked structure behind the chimney that diverts water and snow around it instead of letting it pool against the upslope side. Code requires one on chimneys wider than 30 inches at the roofline — particularly important where snow load sits for weeks.
5 icon

Can I just caulk the flashing myself?

Caulk on failed flashing buys a season at most, and in Michigan often less — it seals the symptom while water keeps entering behind the metal. Proper repair means removing failed flashing down to sound roof deck and setting new step and counter-flashing.
