FAQs
Is a chimney cap necessary?
Chimney caps are necessary to keep animals, water and debris from falling in. They also control wind to minimize the risk of a backdraft.
Do chimney caps keep rain out?
Caps minimize rain and ice accumulation inside the chimney. They must remain partially open to allow exhaust to escape. As such, they do not provide a completely waterproof barrier.
How long does a chimney cap last?
Chimney caps last 3 to 25+ years, depending mostly on the material. Stainless steel and copper ones tend to last longer than galvanized.
How tall should a chimney cap be?
As a general rule, the top of the chimney cap must be at least 5 inches above the top of the flue.
