Installed in Tulsa, Broken Arrow & NE Oklahoma
Duration with SBS polymer-modified (rubberized) asphalt: UL 2218 Class 4 impact rating, a wind warranty up to 160 mph, and the same SureNail® strip. Owens Corning's best shingle for Oklahoma hail.
The Oklahoma verdict
Duration FLEX carries a UL 2218 Class 4 rating, the highest impact rating available. In Oklahoma hail country that is the rating we recommend on any roof you plan to keep for more than a few years. Many Oklahoma insurers offer a premium credit for Class 4 roofs; ask your agent before you choose, and we will put the rating on your invoice so you can claim it.
Compare it with our Class 4 cost-vs-savings math and the hail-damage checklist.
