You charged me almost $200 to tell me that there were bats. That was already known, or you would not have been contacted. You then said you couldn’t do the work until spring, due to snow on the roof. Someone in your business should be equipped to get on a roof in anything other than a lightening storm. They make a ladder, called a roof ladder, that makes roof safely accessible in any condition. I hired another company to do the job and they had it completed within a week.
