A Quick Guide to Fixing Chimney Leaks
Catching a leaking chimney early on and determining the actual cause is essential to prevent the issue from worsening. Periodic chimney inspections can prevent damage and save money on repairs.
Chimney leaks are a common occurrence that several fireplace owners encounter. Extreme weather or heavy rainfall can cause damage, allowing water to penetrate through the chimney. Water and moisture getting in through the chimney can compromise its structural integrity, lead to mold and mildew, damage the attic and ceiling, pose a fire threat, and increase the risk of carbon monoxide exposure.

Here are a few most common causes of chimney leaks homeowners should look into if they suspect a leak. Doing so will help them identify the leak source as a part of regular inspections.
Missing or damaged chimney cap
Every chimney needs a chimney cap over the flue to prevent rainwater, moisture, snow, sleet, critters, debris, and other elements from entering the chimney and the home. A missing or damaged chimney cap can lead to structural issues and an increased fire risk. Install a rust-resistant chimney cap if the chimney does not have one already, or inspect the existing one for repair or replacement.
Broken or worn-down mortar or masonry
Missing mortar in the joint or deep fissures due to exposure to weather elements allows water to enter the masonry, leading to its deterioration and leaks. Bricks used to build chimneys are porous and absorb water. When the moisture penetrates the masonry, the freeze and thaw cycle due to temperature changes can cause a breakdown or other structural issues. Regular inspections can detect mortar issues on time and prevent water intrusion. Chimney tuckpointing and waterproofing can help keep the chimney moisture-free.
Faulty flashing
Flashing creates a watertight seal on the point where the chimney and roof connect. Improperly installed, rusted, shifted, pulling away chimney flashing, or worn-out seals are a few of the most common causes of chimney leaks. It is usually the first thing to check for chimney leaks. If there are any issues with the flashing, call a chimney repair technician to fix the problem and stop or prevent the leak.
Cracks in the chimney crown
The crown at the chimney's top safeguards it against the outdoor elements. Its primary purpose is to prevent water and unwanted moisture from entering the flue and chimney masonry. Over time it can develop cracks or get damaged due to improper construction, shifting chimney structure, and water absorption leading to a freeze and thaw cycle. Fixing the minor cracks quickly or replacing the irreparable chimney crown will prevent leaks or other severe problems.
Poorly built shoulder
The area where the chimney begins to narrow down is called the chimney shoulder. Leaks can develop if the shoulder is built improperly or masonry deteriorates over time. A professional can inspect the shoulder for leaks and fix the issues immediately.
Rusted chase cover, wrong chimney liners, and condensation are other common reasons behind chimney leaks.
Protect the chimney
Regardless of the cause, homeowners should get the chimney leaks fixed as soon as possible by a professional to avoid further damages and costly repairs and replacements. Regular chimney inspections by a reliable chimney service company are the best way to prevent a leaky chimney and ensure its proper and safe functioning.
