We install both. Here is what we think.
DeHart Roofing is certified by both GAF (Master Elite) and Owens Corning (Platinum Preferred). We install both product lines regularly and have no financial incentive to push one over the other. This comparison is based on our real-world experience installing thousands of roofs in the Central Valley.
Product lines compared
GAF Timberline HDZ is GAF's most popular shingle. It is durable, wind-rated to 130 mph, and available in a wide color range. The Timberline NS (no shadow) and Timberline AS II (advanced) offer premium aesthetics.
Owens Corning Duration is OC's flagship architectural shingle. It features the patented SureNail strip for superior wind resistance (130 mph). Duration Premium, Duration Flex, and Duration COOL offer specialized performance.
Warranty comparison
GAF Golden Pledge (available through Master Elite contractors): 50-year non-prorated material warranty plus 25-year workmanship warranty including tear-off costs. This is GAF's best warranty.
Owens Corning Platinum Protection (available through Platinum Preferred contractors): Lifetime material warranty plus 25-year workmanship warranty. Non-prorated for the first 10 years. This is OC's best warranty.
Both warranties are excellent. The key difference: OC's Platinum Protection is only available from top 1% contractors, while GAF's Golden Pledge is available from top 2% contractors.
Which should you choose
Both are excellent products. GAF Timberline offers a slightly wider color selection. Owens Corning Duration has the SureNail advantage for wind resistance. In practice, both perform similarly in the Central Valley. We help you choose based on color preference, warranty terms, and budget during your free inspection.
