The chimney is susceptible to damage from moss. Both crown and mortar joints are in danger from the roots of moss digging into the mortar and tearing it apart, as you can see in the pictures below.
If unchecked, the moss can completely rip apart both crown and mortar joints, destroying your chimney's structural integrity, as you can see in the images below.
The chimney will either have to be tuck pointed, or torn down and rebuilt if the damage affects the chimney's structural integrity, as it has in the picture to the right above. Once the damage occurs to the crown, it will need to be torn off and a new crown re laid. To prevent this from happening, call Metro Chimney to remove the moss and kill the roots once it has been removed. To keep moss from forming and destroying your chimney after this, have it waterproofed with the product that we use, specifically made for chimneys, that is covered with a 10 year warranty by the manufacturer. Call us for details. See the below pictures for two examples of before and after moss removal jobs.
