Sometimes people ask me if there is such a thing as a "Masonry Emergency." The answer is yes; I get several calls a year where a client has an emergency situation. Most of these involve aging chimneys with stones falling, endangering the inhabitants and the roof. Most recently, I was contacted by an individual who had large river stones falling from his chimney and damaging the metal roof below. It was pretty disturbing for them to hear stones hitting the roof when they were inside the house (not to mention the chance of being hit by a fallen stone), and the family was planning a retreat over Thanksgiving and needed the project completed by then. The extreme part of the job was the scaffolding needed to make the repairs. We had to erect three sets of scaffold, 2 of which were on top of the metal roof.
