Leaks in your chimney can lead to water damage, structural issues, and mold growth. Many homeowners wonder who to call for a chimney leak and how to ensure proper repairs. At HealthGardeners, our Chimney Expert Team compiles guidance from trusted home-safety resources to help you understand chimney leak issues, the types of professionals who can assist, and steps to protect your home. This article is for educational purposes only; always consult a licensed chimney or roofing professional for inspections and repairs.
Understanding Chimney Leaks
Chimney leaks happen when water enters the chimney structure through cracks, missing flashing, damaged mortar, or an improperly sealed crown. These leaks can cause:
-
Rust or deterioration of metal components
-
Crumbling bricks or mortar damage
-
Water stains inside the fireplace or on ceilings
-
Mold or mildew growth in attic spaces
-
Reduced fireplace efficiency
Leaks often develop over time due to weather exposure, ice formation, or aging materials. Recognizing early signs helps prevent costly repairs.
Common Causes of Chimney Leaks
-
Damaged Crown or Mortar Cap: Cracks allow water to seep into the chimney.
-
Faulty Flashing: Metal flashing seals the gap between the chimney and roof; damaged or loose flashing is a common leak source.
-
Cracked Bricks or Mortar: Water penetrates gaps in masonry.
-
Clogged Chimney Drainage: Debris prevents proper water runoff.
By understanding the root cause, you can determine which professional to call for effective repairs.
Who Should Handle Chimney Leaks?
When dealing with chimney leaks, it’s important to involve the right professional to ensure safety and compliance with building codes. Depending on the issue, you may need:
Chimney Repair Specialists
These licensed professionals assess structural damage, damaged crowns, and flue problems. They can:
-
Inspect the chimney for cracks, gaps, or damaged mortar
-
Repair or replace crowns, caps, and flues
-
Apply waterproof sealants to brickwork
A certified chimney repair expert ensures that the leak is properly addressed without causing further damage.
Roof and Flashing Contractors
Leaks often stem from the roof-chimney junction. Roof specialists can:
-
Inspect flashing around the chimney
-
Replace or reseal metal flashing
-
Check for roof damage contributing to water entry
For combined chimney and roof leaks, calling both a chimney specialist and a roofing contractor may be necessary.
Home Inspectors
A professional home inspector can identify the source of persistent leaks, helping you decide whether to call a chimney or roofing professional. They provide a detailed assessment but usually do not perform repairs themselves.
Steps to Take Before Calling a Professional
Even before a professional arrives, homeowners can take safe steps to prevent further damage:
-
Document the Leak: Note when and where water appears.
-
Remove Debris: Clear leaves or obstructions from the chimney top.
-
Protect Your Home: Place buckets or towels to catch dripping water.
-
Avoid DIY Repairs on the Roof: Do not attempt flashing replacement or crown repairs yourself, especially if the roof is steep or slippery.
These actions help professionals identify the source faster and prevent worsening damage.

When you hire a chimney repair or roofing professional, they typically follow a structured process:
Initial Inspection
