Damaged Chase Covers

Damaged Chase Covers

Chase covers might not be the most visible aspect of a chimney, but they play a vital role in protecting it from the elements and maintaining its structural integrity. However, like any component of a chimney, chase covers can suffer damage over time due to weather, wear and tear, or poor installation. In this blog post, we will explore the signs of a damaged chase cover, the risks associated with neglecting the issue, and the solutions to rectify the problem.

Understanding Chase Covers

Before delving into the issue of damaged chase covers, let’s first understand what they are. A chase cover is a protective lid made of metal (usually stainless steel, galvanized steel, or copper) that sits on top of a chimney chase. A chase is a structure that encloses a chimney on the exterior of a building, commonly found in houses with prefabricated or factory-built fireplaces.

Chase covers serve several crucial purposes:

  1. Preventing Water Intrusion: Chase covers act as a barrier, preventing rain, snow, and other forms of moisture from entering the chimney, which could cause damage to the chimney’s structure and compromise its efficiency.

  2. Protecting Against Debris and Animals: They keep debris, leaves, branches, and animals from entering the chimney, ensuring it remains clear and safe for use.

  3. Enhancing Aesthetics: Chase covers contribute to the visual appeal of the chimney, providing a polished and finished look to the structure.

Signs of Damaged Chase Covers

Detecting a damaged chase cover is essential to address the issue promptly and prevent further damage to your chimney and home. Here are some common signs of a damaged chase cover:

  1. Rust and Corrosion: Rust and corrosion are clear indications that the chase cover is deteriorating. Rust weakens the structure and compromises its ability to provide adequate protection against moisture.

  2. Water Stains on Walls or Ceilings: If water is seeping into the chimney due to a damaged chase cover, you might notice water stains on the walls or ceilings near the fireplace. This can also lead to a musty odor.

  3. Visible Holes or Gaps: Any visible holes, gaps, or cracks on the chase cover allow water, debris, and animals to enter the chimney. This compromises its functionality and safety.

  4. Sagging or Deterioration: Over time, chase covers can sag or show signs of general deterioration. This is a clear indicator that the cover is no longer structurally sound.

  5. Rusting Chimney Chase: If the chimney chase itself is showing signs of rust, it’s likely that the chase cover is no longer effectively protecting it from moisture.

Risks of Neglecting Damaged Chase Covers

Ignoring a damaged chase cover can have serious consequences, impacting both your chimney and your home. Some of the risks associated with neglecting this issue include:

  1. Water Damage: A damaged chase cover allows water to enter the chimney, leading to water damage to the chimney structure, walls, ceilings, and potentially causing mold growth.

  2. Structural Damage: Moisture seeping into the chimney can weaken its structure over time, posing a risk of collapse or further damage that can be expensive to repair.

  3. Fire Hazard: Debris accumulation due to a damaged chase cover can become a fire hazard if ignited by sparks or embers from the fireplace.

  4. Increased Repair Costs: Ignoring a damaged chase cover can escalate repair costs, as the damage may extend beyond the cover itself to the chimney structure and surrounding areas.

Solutions for Damaged Chase Covers

Addressing a damaged chase cover promptly is crucial to avoid further deterioration and associated risks. Here are the steps you can take to rectify the issue:

  1. Chase Cover Replacement: If your chase cover is significantly damaged, rusted, or corroded, it’s advisable to replace it with a new, durable chase cover made from quality materials such as stainless steel or copper.

  2. Professional Inspection and Installation: Seek assistance from a professional chimney sweep or a certified technician to conduct a thorough inspection of your chimney and install a new chase cover correctly.

  3. Regular Maintenance: Implement a regular maintenance schedule for your chimney, including inspections and cleanings, to detect any issues early and address them promptly.

  4. Quality Materials: When replacing a chase cover, opt for high-quality, durable materials that are resistant to rust and corrosion to ensure a longer lifespan and optimal protection for your chimney.


In conclusion, ensuring that your chase cover is in good condition is crucial for the longevity and safety of your chimney. Regular inspections, prompt repairs, and using quality materials are key to maintaining a functional and efficient chase cover that protects your chimney and home from the elements. Don’t overlook the significance of a chase cover; it’s a small component that can make a big difference in the overall performance and safety of your chimney system.
