I need a roof soon (1960 ranch, tear off, climbable, 31 squares) was thinking 30 lb felt, bidders want 15 lb, I am looking at Owens Corning synthetic deck protector "felt" as a possible upgrade, and also a 35? lb dimensional shingle, (Indiana). Anyway, I think labor is the biggie so I will go for the better materials as possible with probably small incremental cost. Any other upgrades? Hurricane straps? Comments?
