GAF Timberline® AS II (ArmorShield II) Shingles
Installed in Tulsa, Broken Arrow & NE Oklahoma
SBS-modified (rubberized) asphalt shingles that pass the UL 2218 Class 4 impact test. Formerly sold as ArmorShield II. The GAF shingle we recommend most often for Oklahoma hail.

The Oklahoma verdict
Timberline AS II 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.
