Chimney caps are the top-most protective cover on a chimney.
They act as a barrier to small animals, spark arrestors, as well
as keeping rain water out of the flue. Water erodes the mortar
and longevity of the chimney.
Chimney caps as spark arrestors are very important because they
keep sparks from jumping out of the chimney and lighting the roof
on fire. What’s more important than preventing the house
from catching fire? All you have to do is buy a chimney cap and
install it. Don’t try to make your own. That never works
out.
Chimney caps also help keep small animals out of the chimney.
Birds, raccoons, cats, etc., all pose a threat to the safety of
the chimney. They are an important preventative safety feature
of any chimney, masonry or prefab.
