A proper Chase Cover is 26 gauge galvanized sheet metal hood that covers the top of a chimney that contains one or more factory built, prefabricated fireplaces and their venting systems (chimneys). The Chase Cover should have a 4-inch down hang, closed and sealed corners, and incorporate a drip edge. The chimney pass-through should be extruded (pressed) into the main body of the Chase Cover. This eliminates leaking and allows room for expansion and contraction of the chimney as it heats and cools. In addition, a storm-collar and chimney cap are added at the time of the installation to insure proper water shedding.

Most chase covers installed at the time of original construction, were built of a very thin 30 gauge sheet metal, which was bent on the construction site, usually by hand. This resulted in a poor fitting cover that did not allow for expansion, contraction, or proper water shedding, causing excessive wear, rusting and leaking into the chase cover and ultimately the fireplace.

Our Chase Covers are customized to fit your chimney’s exact specifications. We us highly trained sheet metal professionals to make our chase covers, specifically for the Chimney Department.

By providing proper water shedding of the chimney, a properly sized Chase Cover prevents water damage and discoloration (rust stains) of the wood chase and preserves the integrity and safety of your prefabricated (metal) fireplace. It also enhances the appearance of your home.

Our custom built Chase Covers carry a 25 year “no rust through warranty.”
