What are chimney caps for?
A chimney cap is a metal cover that fits over the top of your chimney flue. It's one of the most cost-effective ways to protect your chimney — and your home — from a range of problems.
- Keeps rain and snow out of the flue, preventing moisture damage
- Blocks birds, squirrels, and raccoons from nesting in the flue
- Contains sparks and embers that could land on the roof
- Reduces downdrafts that push smoke back into the home
- Extends the life of the flue liner and firebox
