A chimney cap is the fitted metal hood that covers the top of your chimney. A chimney cap plays an important role in your chimney system and helps your chimney perform at its optimum level. They also add curb appeal to your home!

Keeps Rain Out
First and foremost, a chimney cap will block rainwater from getting inside your chimney. Water damage is a chimney’s biggest enemy and can ruin the liner, dampers, and mortar joints. Excess moisture can also cause mold and mildew problems which can spread to the interior of your home.
Prevents Exterior Fires
A chimney cap will act as a barrier to any flying sparks and hot embers that travel up your chimney. If a chimney cap is not present, hot sparks and embers can potentially fly out of your chimney and land on your chimney or nearby trees and catch them on fire.
If you don’t have a chimney cap and use a wood-burning fireplace, you will most likely experience a wind-induced downdraft that will fill your home with smoke and toxic gases. Chimney caps can help prevent downdrafts and some are specially designed to.
Keeps Animals Out
Birds, bats, raccoons, and other animals have easy access to your chimney if it is uncapped which isn’t great for you or the animals. If these animals get into your chimney, they can not only damage the structure of your chimney and make it impossible for you to use your fireplace, they also expose your household to bacteria and disease. Capping a chimney is the best solutions to keeping animals out of your chimney.
Keeps Out Debris
Leaves, twigs, trash, and other debris can fall into your chimney causing blockages. A chimney cap will prevent debris from getting into your chimney and make sure your chimney is venting properly.
