What is a Chimney Cap?
A chimney cap sits on top of the chimney and protects your flues from debris, rain, and snow. It covers the chimney like a hat and usually has mesh around it to keep animals out of your chimney.
Chimney caps sit on the uppermost part of the chimney, the crown, and is the first line of defense against the elements. The chimney crown also works to keep water out of the chimney, but the cap has the mesh sides to allow for venting
Do I Need a Chimney Cap?
We highly recommend having a chimney cap installed. Not only does it significantly reduce the amount of water that enters your home, but it also works as a spark arrestor, preventing sparks from existing the chimney onto your roof or nearby trees. Having a chimney cap can also prevent animals from entering and potentially dying inside of your chimney, which can cause health issues. Read more about why we think chimney caps are essential.
How Tall Should A Chimney Cap Be?
Your chimney cap should be at least eight inches above the top of the flue tiles that it’s covering, though it is ideal for it to be more than eight inches above. This will ensure that the chimney cap doesn’t interfere with your chimney’s draft, which controls how well smoke is pulled up and out of your chimney.
What is a Chimney Cap Made Of?
Chimney caps are most often made of stainless steel or copper and come with a lifetime warranties against defects and corrosion. Caps made or lesser quality steel often rust and can stain the chimney and surrounding roof.
Can I Install My Chimney Cap Myself?
