Reasons For Chimney Leaks

The ubiquitous masonry chimney is one of the most recognizable features of a home. Its height, perched above the roof, is essential for expelling smoke and combustion gases from the residence while folks inside enjoy a warm and cozy space. However, this visibility means that the chimney is continuously exposed to the weather, whether it’s a winter snowstorm, spring rains, or humid summers, they all take their toll on masonry surfaces. For these reasons, chimney leaks are among the most common problems for homeowners.

Why Is My Chimney Leaking?

Is it raining in your fireplace? Do you see wet spots on the walls or ceiling near the fireplace or stove? Several vulnerabilities can compromise the integrity of your chimney, paving the way for water intrusion:

Damaged or Missing Chimney Cap 

Perhaps the most common reason for chimney leaks is a missing, damaged, or improperly fitted cap. Without a secure cap, rain and snow fall directly into the flue, leading to significant leaks, typically showing up as puddles in the firebox. Installing a properly fitted chimney cap is the first line of defense against precipitation, debris, and even curious critters. A full-width chimney cap also helps protect the crown.

Chimney Crown Cracks

The chimney crown, that concrete or masonry slab at the very top of the chimney surrounds the flue pipe, preventing water damage to the interior masonry walls. However, exposure to hail, thermal expansion, and settling can cause cracks and deterioration in the crown. Once compromised, water can easily penetrate the chimney’s structure. For minor crown damage, products like EverCrown offer a viable repair solution, sealing those initial cracks and preventing further damage.

Flashing Failures

Flashing is the sheet metal that seals the space where the chimney meets the roof. Its watertight seal directs water away from this vulnerable intersection. If the flashing is improperly installed, corroded, bent, or has loose or missing sections, water can easily find its way inside, damaging the attic, ceiling, and walls.

Damaged Masonry

Brick and mortar, while durable, are not entirely impervious to water. After years of exposure, the porous masonry surface can crack, allowing water to be absorbed like a sponge. Cracks in the mortar joints, spalling (where brick faces flake off), and general deterioration provide direct pathways for water to enter the chimney structure.

Preventing Chimney Leaks

Proactive measures are always the most cost-effective way to avoid the headache and expense of chimney leaks. Here’s how you can bolster your chimney’s defenses:

• Regular Inspections: Annual professional chimney inspections are paramount. A qualified chimney sweep can identify potential problems early, such as minor cracks in the crown or flashing issues, before they escalate into significant leaks.
• Invest in a Quality Chimney Cap: Ensure your chimney has a properly sized and securely installed chimney cap. This simple addition offers significant protection against rain, snow, debris, and animals.
• Maintain the Flashing: Regularly inspect the flashing around your chimney for any signs of damage, corrosion, or loose sections. Resolve any issues promptly with professional repairs.
• Waterproof Your Masonry: For long-lasting protection against water intrusion through porous masonry, consider professional waterproofing treatments. RainTite, with its advanced weather resistance formula, is specifically designed to penetrate and seal masonry surfaces, providing a reliable barrier against moisture. This helps prevent water from seeping into the pores and cracks of the brick and mortar, safeguarding the chimney’s structural integrity.
