A Chimney Cap Acts Like a Roof for the Flue

Every chimney needs a cap for the same reason every house needs a roof. Chimney flues can be 12 inches square or larger and chimney caps or “spark arrestors” are used to cover the flue opening.

Keep Out Animals And Elements: Rain, Sleet And Snow

  • Remember, water is the biggest cause of damage to masonry — but a chimney cap can prevent water penetration. Keeping water out of a flue is a good way to slow down deterioration to a masonry chimney.
  • The stainless steel mesh is perfect for keeping out squirrels, birds and raccoon’s.
  • Chimney caps also prevent leaves, twigs and other debris from entering any type of flue ( including oil and gas furnaces), which could lead to a blockages or chimney fires
  • AND they help eliminate wind-induced downdrafts. This makes it easier to keep that fire or furnace burning.

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 discuss what can come out of the flue that you might not want to: sparks and embers. The mesh that surrounds the cap works to keep those sparks and embers in their place and not let them escape out onto the roof where they could potentially start a roof fire.

Don’t Lose that Warranty

Most caps are fastened to the top of the flue and must be attached by a certified chimney sweep in order to be covered by the warranty. Just another reason to deal with a reputable company that is dedicated to certification and education!
