Also called chase tops, chimney chase covers are metal coverings made generally for the wood-framed boxes that rise along the side of a house or protrude from the roofline and contain a chimney flue. A chimney chase cover is designed to protect a home, keeping harsh weather conditions and pests from entering through the cavity where your flue or chimney liner runs. A masonry or brick chimney often will have a concrete chimney crown that acts in a similar way, although you might use a chase cover on a masonry chimney, depending on your application.
Chimney chase covers are made from four main types of materials: galvanized steel, aluminum, stainless steel, and copper.
- Galvanized steel is the lowest cost option and comes standard on many new home builds. It is known to rust quickly and may need replacement in a short period of time.
- Aluminum does not rust, and is considered too soft, and is easily damaged by hail. It is not a good choice for most applications and is hard to get in the required sizes.
- Stainless steel is the strongest and most popular of all the available choices. And while it might cost more than galvanized, it doesn't rust and will virtually last forever.
- Copper is the highest quality and costs nearly 2x more than stainless steel options. They are the perfect choice for luxury and historic houses. They do not rust but weather to a protective blue-green patina.
- Powder coating is also available for stainless steel options. With many colors to choose from, including custom blends its easy to find a color that matches your home's look and trim colors.
Should you replace your chimney chase cover?
If you have read this far, you likely already know if your chimney chase cover needs replacement. That said, a chimney chase cover needs replacement once rust starts to form or you notice leaks coming from your chimney. Rust, the most common indication you need a replacement, can drip down the side of your chimney chase and stain masonry, siding, and your roof. You will likely notice the telltale rust streaks along your siding or brickwork before you see any other signs.
Don’t wait; the longer a damaged or end-of-life chase cover remains in place, the higher the likelihood you will need more extensive repairs to the chimney chase, your roof or siding.
