What are Chimney Caps? Why do I need one?
Chimney caps are simply a cap to cover the vent or chimney on your home. A chimney is essentially a hole in your roof. If not properly covered, a whole host of problems could occur from various things entering that outlet.
Exposing your chimney to Mother Natures elements can lead to extensive and costly damages.

Additionally, water that seeps into existing cracks may expand and cause more damage. Without a flue cap, rain and coal soot mix to form sulfuric acid, which is particularly damaging to your chimney and not exactly something to which you want your family exposed.
Without a fireplace chimney cap, critters may crawl, slide, or fly into the chimney as well. Its a warm and protected space that animals find appealing in cold weather. Not only can this lead to the untimely death of the fuzzy creature, but some woodland animals carry parasites, rabies, and other unpleasantries that can be transmitted to your home and family. Even worse, an animal caught in a flue can cause fires, carbon monoxide backup, and very unpleasant smells if not detected.
Finally an open chimney without a flue cap or fireplace chimney cap is a fire hazard. Embers and sparks can fly from the top and land on your roof, dry leaves in your rain gutters, or surrounding foliage and quickly cause a blazing and lethal fire.
