A chimney chase cover is a metal covering, generally for a wood-framed chimney chase, which keeps water, snow, debris, and animals from entering your chimney. These covers resemble the lid of a shoebox and are usually standard with pre-fabricated fireplaces.

Galvanized steel chase tops do in fact last long periods of time and that’s what we do 99% of our chase tops in, because its far less expensive than stainless steel and when properly bent & cross-broken, will easily last 10+ years.

A damaged or deteriorating chase cover can be easy to detect since water runoff from a rusty chase cover can cause unsightly discoloration on the chimney.  Heat produced from burning a fire and various environmental conditions contribute to the deterioration of the galvanized coating on chase covers. Once this galvanized coating has disappeared, the metal is left completely unprotected and begins to rust. Once rust is spotted, repairs or replacement should be done immediate. Even a small hole or crack in a chimney case cover can result in extensive water damage which can lead to a number of costly repairs. If you quickly address the situation, you may be able to prevent serious water damage or other issues that can require expensive repairs.

Chase Cover Design

You should ensure that your chimney chase cover is made to exact specifications to your chimney chase. There should be ¼ to ½ inch space all the way around and the cover should be spaced off the chase by about 1/8 to ¼ of an inch to allow for ventilation.  Chase covers also include a large round band called a “storm collar” where the chimney liner venting comes up and is capped off with a “termination cap.”  The storm collar helps to shed water and forms a waterproof seal, helping to keep water and moisture out of your chimney.

Common Issues Caused by Bad Chimney Chase Covers

Coverings such as chimney caps, shrouds, chase covers, and other custom chimney toppers are important for preventing moisture, animals, leaves and other debris from falling down into the chimney causing damage or blockages. Water & moisture is your chimney’s worst enemy and if your chimney chase has deteriorated to the point that it is no longer keeping water and moisture out, you may be facing expensive repairs in your future.  Common issues caused by chimney moisture damage include: rotting wood frame and walls, mold, deterioration & rusting of your firebox, deterioration of chimney liner and masonry components, and possible carbon monoxide leaks.

Materials Used for Chase Covers

Galvanized steel, aluminum, copper, and stainless steel are all materials that a chimney case cover can be made of. Each one has its own advantages:

Chimney ChaseGalvanized Steel– These chimney chase covers are the most common and most economical to use. They can last 10 or more years if properly built and installed.

Aluminum- These chase covers do not rust, but may be damaged easily since the metal is generally too soft to function well as a chimney topper.

Copper- Copper is considered the highest quality choice, but these chase covers are typically the most expensive. The aesthetic appeal has enticed many homeowners to feature a copper chase cover to enhance the appearance of their chimney.

Stainless Steel- Stainless steel is the strongest material used to make chimney chase covers.  It costs more than galvanized steel but never rusts and should never need to be replaced which makes it a great option for homeowners who don’t want to worry about regular chimney chase cover maintenance .
