A proper Chase Cover is a 26 gauge stainless steel or copper 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 ensure proper water shedding.

Why Would A Chase Cover Need Replacing?
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. What Makes Our Chase Covers The Best? Our Chase Covers are customized to fit your chimney’s exact specifications. We use highly trained stainless steel professionals to make our chase covers, specifically for the Chimney Department.

Benefits of a Properly Sized Chase Cover 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.
