Did a condo transition inspection, Sunday.
30 unit building, originally built in 1927. Flat roof with a big chimney (for the old, common boiler. Now, each unit had its own furnace.). Also on the roof were about 7 small (4’ H, 3’ wide and 2’ deep) brick chimneys that, most probably, served the small, gas fireplaces / space heaters in the original configuration.
Was looking in one of the top floor units (they had had some water, so the ceiling was open) and I found this.
There, flush with the underside of the roof decking, was the cut off bottom of one of the small chimneys. They just took out the underlying brick and left the chimney, unsupported (well, probably held up by the roof flashing, which was pretty good).
Association rep was shocked (she had one in her unit, as well, right over her new granite countertop and sink) and the buillder kept saying “Hey, there is no problem. The code inspector said it was OK.”. I told him, “Hey, hows about we call them up, right now, and make sure, shall we?”
Please, someone, calculate the weight of this thing and guestimate what would happen if the flashings, suddenly, decided they didn’t want to hold this anymore.
Recommended that they remove the chimney, or, at least, support it with some beams between the roof rafters.
