This house was damaged after the September hailstorm that came through Krebs, OK. We upgraded this roofing system to Class 3 Impact Resistant Shingles. For this installation, we used Owens Corning TruDef Duration. Owens Corning is one of the best leading shingle manufacturers in the Nation. Also, we used flat roofing material for the low pitch section, which the previous contractor failed to ensure it was done right the first time.
