A chimney cap prevents rain from entering the chimney, causing damper and firebox rust leading to expensive repairs.
Most chimney caps will not allow birds, bats, squirrels or other animals to enter the chimney to nest.
Where certain wind conditions exist, a chimney cap will discourage downdrafts. Some caps are specifically designed to prevent wind from blowing across the chimney, others actually create and updraft when wind blows through them!
Many chimney caps include 18 gauge wire mesh to reduce the amount of sparks and large ash that is normally blown into the air and onto rooftops.
