The Freeze/Thaw Effect
As with most potential issues, it starts small, with erosion from wind and rain that over time cause minor cracks in the masonry on the crown and in between bricks or stone chimneys. Once there are cracks in the masonry crown or between the mortar joints on your chimney, rain water and moisture from melting ice and snow seep in and freeze overnight when the temperature drops below freezing.
The water then expands just like it does in ice trays in your freezer, and as it does, the cracks and gaps widen. Once the gaps and cracks get to the point where the masonry is no longer bonded to itself, the bricks can become loose or the mortar crown can lift from the top course of masonry. Both of these issues mean your chimney system is being damaged more and more with time, weather and ever-changing temperatures.
