Chimney chase covers are essential components that, much like other types of chimney toppers, redirect rainwater and keep out debris from the chimney chase. Any minor opening or crevice in these covers can lead to significant water damage, necessitating expensive repairs.

The rectangular-shaped covering on top of a chimney, known as a chimney chase cover, is commonly found on chases linked to factory-built fireplaces. When the chimney topper becomes damaged and fails to repel moisture, costly repairs may be required. One way to identify a damaged chase cover is by observing rust stains on the sides of the chimney resulting from water running off the cover. Immediate repairs are crucial upon detecting rust damage, as failure to do so can cause water, debris, and leaves to accumulate in the center of the cover, leading to further deterioration. This can result in cracks and holes developing in the cover, allowing water to penetrate the structure. There are generally two types of chimney chase covers: metal chase covers and masonry chase covers. Metal chase covers are made of galvanized steel, stainless steel, aluminum or copper and are installed over the top of the chimney chase to protect it from water damage. Masonry chase covers, on the other hand, are made of brick, stone, or concrete and are built into the masonry of the chimney itself. There are several options available for constructing custom chase covers, but stainless steel chase tops & chimney cap are a preferred choice due to their resistance to rust.
