What you need to know about chimney chase covers

Chimney chase covers are fundamental to protect not only the top
of your chimney but also its sides. A cover is important to help eliminate
water absorption on surfaces making it slide off without compromising
the chimney’s structure. It is also relevant against animals such as birds
and bats from entering your house through the chimney. Chimney chase
covers are basically situated on top of your chimney and is visible from
the outside.

Chimney Crown VS Chimney Chase Cover

You might be wondering what the difference between a chase cover
and a chimney crown is. They are almost the same thing but what differs
them is the material in which they are made of. Chimney chase covers are
made of metal, the best option being stainless steel to avoid stain, rust and
water leaks.
On the other hand, a crown is made of concrete usually used on
masonry chimneys. It basically has the same function of a chase cover,
however, in some cases, it needs to be repaired and sealed more often to
avoid cracks and help with water deflection.

Leaking & Rusting Chimney

Leaking chimney chase covers can occur, and that is due to cheap
materials or even improper installation. If they are not installed properly
or cut correctly it will cause water or snow to enter your chimney through
its gap. If you notice water coming in your chimney, damp bricks, white
stains, discoloration or any type of moisture, make sure to contact a
professional and they will be able to detect its cause. Your crown or chase
cover might need to be patched, rebuild or reinstalled.
