Benefits of a Healthy Chimney Crown

Prevent Leaks

A functioning crown stops water from seeping into the chimney and damaging the flue liner, damper, and firebox.

Protect Your Home

Prevents water leaks that can lead to structural damage and mold growth inside your home.

Maintain Chimney Efficiency

A damaged crown can disrupt airflow and lead to poor burning in your fireplace.

Extend Chimney Lifespan

A healthy crown protects the chimney structure from deterioration caused by moisture.

How Crowns are Built

Even though the chimney crown may seem simple enough, a lot goes into the construction of a quality crown.

 If it’s to withstand the rain and moisture, season after season, the chimney crown should be 2 inches thick at its thinnest point. Anything less than that will deteriorate much more quickly.

A quality constructed crown should be angled on the top so that water runs off of it, as opposed to settling on its surface. If not properly angled, water can puddle and will eventually wear through the crown.

 We’ve seen many chimney crowns end right at the edge of the masonry chimney stack. This type of design drops water directly down into the masonry chimney stack and onto the flashing, where it can do extensive damage and lead to major leaks. A properly built crown will extend past the masonry chimney stack by at least 2 inches.

If you want a chimney crown that lasts, it should be constructed of concrete and reinforcing metal or steel mesh. If constructed of regular mortar, it’s only a matter of time before cracks develop and the crown deteriorates.
