Why Your Chimney Should Be Domed

What Is A Chimney Dome?

A chimney dome is a relatively easy and generally inexpensive way to ensure proper water runoff on the top of your chimney. It is comprised of masonry cement and an adhesive admixture (glue) that increases the bond between the dome and the chimney top or crown.

Why Dome Your Chimney?

By adding a slope of masonry cement around your flue tile and chimney liner, you prevent water from sitting on the crown. In the late fall and early spring months, when water freezes at night and thaws in the day time, water stuck on top of your chimney can cause erosion and even form cracks. Also, the added cement secures the individual parts of the crown.

How Often Do You Need To Dome Your Chimney?

There is no set duration that a dome will last. It all depends on the individual chimney’s exposure to weather, as well as the health of the rest of the chimney. Chimney’s should be inspected every so often in order to get ahead of any further damage that may be caused by improper water runoff.

Why You Should Hire A Mason To Dome Your Chimney

Repairing the crown of your chimney can be a relatively quick job, but should be handled by someone properly trained in working at heights. Many chimneys can be difficult to access and require scaffold, taller than average ladders and proper harnesses to be worked on. Beyond that, you want an expert who knows the proper repair techniques for each specific job, each individual chimney requires it’s own custom dome.

How Do I Know If My Chimney Needs To Be Domed?

While most home owners have no easy access to the tops of their chimneys, you may be able to tell from the ground if your chimney needs to be properly domed. Water leaking into your fireplace can be a sign that repair is needed. Check your fireplace for water during heavy rain.
