The Importance of a Chimney Cap

Ahhh springtime. The trees are budding, the bees are buzzing, and all of our favorite backyard critters are back for another season. While our furry and feathered friends seek out their summer homes, you'll want to make sure your chimney is “off the market” by installing a chimney cap.
What is a Chimney Cap?
A chimney cap is a protective covering that sits at the very top of your chimney. Usually made of stainless steel or copper, a chimney cap keeps out snow, ice, and debris during the burning season. It also contains chimney sparks to reduce the risk of a roof fire. In the off-season, a chimney cap prevents birds, squirrels, raccoons, and even bats from building nests or taking shelter.
Chimney Critter Problems
Once inside, these “seasonal guests” can cause serious problems:
Blockages from nests or debris that prevent proper ventilation during the burning season (and the risk of carbon monoxide build-up)
Odors from nesting materials, droppings, or deceased animals
Health hazards from bacteria and parasites
Structural damage from scratching, chewing, or acidic droppings
A properly installed chimney cap acts as a barrier, preventing animals from entering in the first place.

Now is the Time to Install a Chimney Cap
Spring or summer is the perfect time to install a chimney cap and take care of any other necessary maintenance. The weather is more reliable, and maintaining your chimney now ensures it will operate safely and efficiently during the burning season.
