I have this leaking valley to replace, and I am wondering what to do with that ‘angle’ section above. The valley metal overlap is supposed to be approx. 12", but nothing like that will be possible in duplicating that current bend at the top. Any suggestions on what to do with that short patch there…use low slope flat roof material & treat it like a cricket? That small section is low slope and I dont know that shingling it would be an option…Thanks!!
