A proper chimney cap prevents debris from accumulating in the chimney, which can cause a fire hazard. This is especially important during autumn as leaves and branches fall off trees in preparation for winter.Deterioration. Caps that cover the entire top of your chimney protect against deterioration caused by moisture and rainwater. Both can damage your chimney, the damper, and the firebox. Water can also harm your walls and erode brick over time. These hazards often go unrecognized.

A powerful draft can also blow smoke or ash into your home if your chimney isn’t properly covered.Animals.
