I have no chimney, but I do have a low sloped metal roof in snow country. Sometimes (like last winter the ice collected at the eaves up to 8" thick, before it dropped to the ground) Am I better off building a simple chimney outside the building, so that the mechanical action of the forming ice won't defeat the strength of a masonry chimney? Or would you suggest that I go through my metal roof so that the chimney is moderately warm (less creosote) and try my hand at waterproofing a metal roof against leaks (with no approved fittings) and then fighting the ice formation that would put pressuere against the chimney standpipe?
