A residential home with an uncapped chimney leaves a huge hole straight into the home. This will need to be closed by adding a damper to prevent various problem from occurring. A chimney cap offer many benefits to homeowners they may not even realize. The opening of a chimney is a means for exhaust or smoke from a fire to vent into the air. However, rain, snow, and even animals can easily enter chimneys that are not capped. Another reason to have us installed is to keep burning embers in the chamber so they do not fly up on the roof.
