A Chimney Cap Acts Like a Roof for the Flue

Every chimney needs a cap for the same reason every house needs a roof. Without a cap, the chimney flue and crown are unprotected against the elements. You see, chimney flues are large openings pointing skyward. Chimney caps with “spark arrestors” are used to cover the flue opening and keep out moisture, animals, birds, and other things.

Why It’s Important to Keep the Elements Out of Your Chimney

  • Remember, water is the biggest cause of damage to masonry —but a chimney cap can prevent water penetration. Keeping water out of and off the chimney flue is a good way to prevent deterioration to a masonry chimney.
  • The stainless steel mesh on a chimney cap and spark arrestor is perfect for keeping out squirrels, birds and raccoons.
  • Chimney caps also prevent leaves, twigs, and other debris from entering any type of flue (including oil and gas furnaces) and causing blockages or chimney fires.
  • AND they help eliminate wind-induced downdrafts. This makes it easier to keep that fire or furnace burning without interruption.

What to Keep IN Your Chimney

While we are always talking about what can potentially come into the flue, when talking about caps, we need to also discuss what can come out of the flue: sparks and embers. The mesh that surrounds the cap works to keep those sparks and embers in their place and prevent them from escaping out onto the roof or into brush near the home where they could potentially start a roof fire.
