A chimney cap is a black or silver manufactured box that sits on top of your chimney. It has four major purposes:
1 - It prevents sparks and burning debris from getting out of your chimney onto the roof or surrounding areas. Chimney caps are sometimes
called “spark arresters”.
2 - It keeps rain from entering your chimney. Water is very destructive to the inside of your chimney. It mixes with the creosote
inside your chimney, which eats away at the mortar inside. Also, rain causes the metal parts inside your fireplace, such as the damper,
to rust. A chimney cap acts like an umbrella on top of your chimney to keep out the rain.
3 - It keeps out birds, squirrels and other animals.
4 - It keeps out leaves and branches.
