GAF Timberline CS: Golden Pledge warranty available through GAF Master Elite contractors (50-year non-prorated, 25-year workmanship).

Josh Brooks Construction Recommendation

Both are excellent Class 4 products for Colorado. Owens Corning Duration Storm has a slight edge in shingle nail zone innovation (SureNail strip). GAF Timberline CS has the better warranty path with Golden Pledge. For most Colorado homeowners filing an insurance claim, either product is an excellent choice. Josh Brooks helps you choose based on your specific insurance carrier’s discount program and your long-term goals.
