Not a DIY for most; it means working on the roof at the chimney top, so a fall is the main risk.
Common questions
Why cap?
A cap keeps rain, animals and debris out of the flue. Water can damage the liner and bricks, and a mesh keeps sparks inside.
Is it required?
Often yes by code in many places, and always smart. Check with your town. It is a low-cost way to protect the chimney.
Stainless or copper?
Stainless steel costs less and lasts for years. Copper looks better and lasts longer, but costs more and may not be worth it for most homes.
