That actually crossed my mind. Maybe it was supposed to be temporary for some reason and was never addressed? But the tar or whatever it is used to seal it? That's just terrible on a rubber roof. Makes me think it wasn't temporary or done by someone with a clue.I didn't go through the roof, but about three weeks ago I ran about 75' of sealtite across a commercial roof for a kitchen exhaust fan. It's supposed to be temporary while the roof gets replaced but if the roofers don't get it together and get finished pretty soon, I might forget about it and my temporary fix might become permanent.
