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). Owens Corning TruDefinition Duration shingles carry a limited lifetime warranty and a 130 MPH wind rating. Color shown is Teak. Call for your free estimate: 419-212-3200.
