OWENS CORNING RULES! Once again, I’ve got another happy customer who has received the best roof in the business. Remember, I always use synthetic felt, ice guard on all eaves, and super-sealed quadruple layered valleys (ice guard, aluminum flashing, synthetic felt, and shingle overlap). On this particular job, we had to repair quite a bit of rot due to the improper installation of ice guard by the previous crew. This roof is good to go for the next 50 years!
