Chimney crowns play an important part in protecting the chimney system by keeping water from entering between the flue tile and the bricks surrounding the tile. In the winter the water that gets between the flue and bricks freezes and expands, causing the bricks to be pushed away. This is similar to how pot holes are created. 

The photo to the right is a chimney viewed during an inspection last week. As you can see, the concrete crown is deteriorated and worn. When the crown is repaired it should completely cover the brick and be pitched downward to allow the water to flow away from the flue.

This recently repaired chimney is how the crown should look. A metal chimney cap has also been installed to prevent water from entering the flue. This protects the interior flue and its mortar joints which can also be damaged by water.

If you or someone you know has a drone, this is perfect way to examine the chimney to see for yourself how it looks. Binoculars can also be useful from the ground. If you are unable to view above the chimney you can have a mason look at the condition of the chimney. Ask the mason for pictures so you can see the condition of the chimney yourself so you’ll have a better understanding of what repairs the mason is recommending.
