Chimney Chase Covers

As some homes near their 20th year of service, not only are the roofs are losing their serviceability so are
the chimney chase covers.These are the metal covers that are placed on top of the chimney.  They are designed to keep water from entering the chimney and fireplace. They are usually metal, mostly steel.

As you can imagine, with steel comes oxidation and rust.  Many times the rust is so pervasive, it leaves
severe rust stains on the siding of the chimney.

Here is a photo of a nearly completed chase cover we recently installed here in Raleigh.  The cap still has to be reinstalled above the flue.

If you look carefully, you will see the top is "partitioned" or bent in order to prevent water from "standing or ponding" on the top.  Also, we provide a  3/8" "kick-out" on the vertical edges to prevent water from falling directly on the siding below.

This chase cover will provide another 20 years of uninterrupted service.
