One of the most important things you can do to prolong the life of your chimney system, keep everything looking great and working like new is to keep it properly safeguarded against water entry.

What Is a Chimney Crown?

A cement slab that rests atop your chimney stack, the chimney crown seals off the open cavaity of the chimney, leaving room for the chimney flue – where the smoke exits your system.

This part essentially serves as the roof of your chimney, so it takes on the glaring sun, the pounding rain and hail, and the freezing sleet and snow so that your chimney’s interior doesn’t have to. In order to stand up to these elements season after season, the crown must be constructed of concrete and reinforced with mesh.

But it’s not just the materials that determine the longevity and effectiveness of the chimney crown – it’s also the construction!

How Is a Chimney Crown Built?

So, what determines proper chimney crown construction?

  • A sloped, slight mound-like shape to encourage water run-off
  • A thickness of at least two inches (at the thinnest points)
  • An overhang of at least 3 inches all the way around the top of the chimney

The slope prohibits excess water from pooling on the crown for long amounts of time, the thickness ensures water, animals, and other debris can’t easily penetrate it, and the extension beyond the walls protects the brickwork from direct contact with rain and other elements. If a chimney crown isn’t built correctly, it will only be partially effective, and for a much shorter amount of time.

Unfortunately, many contractors build thin, flat crowns out of readily available mortar mix, and construct them without an overhang. It’s easier and faster for them because it requires no additional equipment or materials, but causes a lot of issues for homeowners down the line.

We see this all the time in our industry, but luckily, at Chim-Cheroo, we also have an expertly trained and professional team of Chimney Safety Institute of America (CSIA)-certified technicians. These talented chimney sweeps know how to tear apart a poorly built crown and replace it with one made properly so that it will stand the test of time.
