Does my chimney need a cap?

A chimney cap prevents water from entering the chimney. Moisture can enter the flue anytime it rains, without a chimney cap. This can cause water to get inside the attic or house as it runs down the brickwork. It is best to choose a chimney cap with the mesh siding to prevent critter from entering your chimney.

Beside this, what size chimney cap do I need?

For example an 8″ x 8″ cap may mate to flues from 6″ to 8.5″ in both width and length. If your flue is oval or round you will need to use a top mount style cap. Measure the total crown width and length, length and width of the area surrounding the flue, and the height of the flue if extended.

How do I choose a chimney cap?

A properly sized chimney cap should not interfere with draft. Draft is that which controls how well smoke is drawn up and out of your chimney. The lid of the cap should be at least 5” above the top of the any flue tiles it is covering. Having more clearance than 5” is a good idea.
