Chimney chases are protective structures that surround the flue of your chimney. They are a barrier against weather elements, keeping moisture out and preventing damage to your roof and home. The primary function is to protect the chimney and the roof from water intrusion. 

This highlights the importance of regular inspection and maintenance of these chimney chases. Let's look more into it!

Signs of Chimney Chase Problems

A chimney chase is a long, narrow space that runs from the fireplace up the chimney and through the roof. Your chimney chase may seem fine, however, some problems aren't immediately visible. Here are a few signs to watch for:

Water Stains or Dampness

If you notice water stains on your ceiling or walls near the chimney, it could indicate a leak in the chase cover. Water damage around the chimney can lead to bigger problems, like mold growth or structural damage. Check the chase cover and the flashing for any gaps or cracks.

Rust or Corrosion

Chimney chase covers, especially metal ones, are prone to rusting. If you see rust streaks running down the chimney or notice the cover looking weathered, it's a sign of corrosion. 

Left unchecked, rust can eat through the metal, allowing water to enter the chase. Regularly inspect the chase cover and replace it if rust has compromised its integrity.

Cracked or Warped Siding

Chimney chases often use wood, vinyl, or other siding materials, which can crack, warp, or rot over time. Look for visible cracks or warping on the chase structure, especially near the base where it meets the roof. Extreme weather conditions can cause this damage, weakening the chimney’s protective shield.

Common Chimney Chase Repairs

Considering your chimney is one of the most vulnerable parts of your roof—since it’s different in design from the rest of the structure—it’s important to stay aware of its overall maintenance. Once you identify the issues, it’s time to take action. Here are some practical solutions to repair common chimney chase problems.

Replacing a Chimney Chase Cover

A damaged cover is one of the most frequent problems with chimney chases. If you spot rust or holes in the cover, it’s time for a replacement. Most covers are made from galvanized steel. Installing a high-quality cover can extend the lifespan of your chimney chase and prevent leaks.

Fixing Flashing Leaks

Flashing is the metal that seals the gap between your chimney and roof. Over time, this flashing can crack or come loose. If you notice leaks around your chimney, flashing could be the culprit. 

This will block water from seeping through the gaps and protect the chase from water intrusion. Consult with an expert if you find leaks. 

Repairing Cracked or Warped Siding

For cracked or warped siding, immediate repair is necessary to prevent further damage. In many cases, replacing the affected panels is the best solution. If your chimney chase uses wooden siding, consider replacing it with vinyl or a more durable material like steel.

When to Call a Professional

Some chimney chase issues are simple enough to fix on your own, but others require professional help. If you notice widespread rust, severe leaks, or structural problems, it’s best to call in an expert. Professionals can assess the full extent of the damage and recommend a long-lasting solution.
