A chimney crown in Hebron , CT was deteriorated due to water damage.  The water allows moss to grow , which damages the chimney further , especially in freeze-thaw cycles.  Algae , moss, lichen , or mold on the chimney signifies a problem that water has penetrated the chimney. This can do damage to the interior chimney liner , which is the safety aspect of the chimney venting system. If caught soon , a certified chimney professional could scrape off the moss on the chimney , or in cracks in the mortar and then apply a waterproof product to help prevent regrowth.  In this case , the situation was caught too late , so we had to rebuild the crown, or cement cap as some laymen call it.
