My parents called me because they had a guy come to replace the facia board around their house. The guy told them he charge what he does becuase he will not bend the flashing. He came and started the job and of course bent the flashing all the way around the house. It looks terrible now and my father told him to not even come back to finish. My question is, is there a way to replace the flashing without messing up the existing shingles and do it make it look normal again?
