Chimney Caps or Rain Caps as they are also referred to, are either square, rectangular, or round in shape with a slight outward slope allowing for rain and snow to run off. They are installed on the top of chimneys to prevent rain water from entering the chimney flue which can cause the hardening of chimney soot making it very difficult to remove while annually servicing and cleaning your chimney. Rain water entering a chimney flue when missing a cap, travels down the flue all the way to the bottom and can rust and deteriorate your appliances components prematurely and can leak into human living space commonly misdiagnosed for a roof leak, and pose a risk of mold and odors. Animals also find refuge and sometimes nest and breed in chimney flues when missing the chimney cap.
