I would like my brick chimney removed completely and disposed of and have the roof repaired just in the specific area that the chimney was located. Otherwise the roof is in perfect shape so only the footprint of where the chimney meets the roof needs to be addressed I live in a 100 year old semi detached brick house in downtown Toronto. The chimney is in bad shape and not functional. I will instead have a direct vent gas fireplace installed which does not require any chimney. I would like an approximate cost .
