Benefits of having a chimney cap:

• Reduction of Moisture. The chimney cap functions as an umbrella that keeps rain, snow, sleet, and hail from coming into your home via the chimney. Moisture rusts stainless steel liners, chimney dampers, and chimney mortar joints. At the same time, it also produces toxic mold and mildew.

• Restricts Animal Access. The chimney is a warm, out-of-the-wind dark place to build a nest for birds, raccoons and squirrels. Sometimes wildlife goes into the chimney but can’t get out. If they should die inside the chimney there will be extremely odious smells in your home.

• Blocking of Downdrafts. If the wind blows a strong draft down into your fireplace you could have a smoke-filled living room. The chimney cap prevents windy downdrafts from blowing back into your home.

• Prevent Sparks and Embers. The chimney cap helps prevent sparks from blowing out of the chimney and landing on the roof or some other area that could catch fire.
