Adam Olson and Jesse Simpson, leveraging Heartland Roofing & Siding data, advise choice depends on budget and specific homeowner needs.
Quick Answer
An unbiased contractor's breakdown of the "Big Three" asphalt shingle manufacturers.
If you get three roofing quotes in Iowa, there is a 99% chance the contractors are pitching products from one of three manufacturers: Owens Corning, GAF, or CertainTeed. Together, they dominate the North American roofing market. But which brand actually delivers the best performance against Midwest wind and hail?

Owens Corning (Duration Series)
Owens Corning (the creators of the Pink Panther insulation) revolutionized the shingle industry with their patented "SureNail" technology.
What We Love
- • The SureNail Strip: A tough woven fabric strip embedded in the nailing zone. It provides an incredibly visible target for installers (reducing human error) and delivers unrivaled grip against high winds.
- • Wind Resistance: In our post-derecho inspections, Owens Corning Duration shingles consistently suffered the fewest blow-offs.
- • Color Contrast: Their "TruDefinition" color palettes offer incredibly vibrant, high-contrast aesthetics that boost curb appeal.
The Drawbacks
- • Weight: They are slightly lighter overall than a comparable CertainTeed shingle, relying heavily on the SureNail strip for strength rather than sheer mass.
- • Algae Defense: While they offer StreakGuard, historically their algae resistance has slightly lagged behind 3M-powered competitors (though recent updates have improved this).
GAF (Timberline HDZ)
GAF is the largest roofing manufacturer in North America. Their Timberline series is the best-selling shingle on the continent.
What We Love
- • LayerLock & StrikeZone: GAF's answer to SureNail. They created a massive, highly visible nailing area that mechanically fuses the shingle layers together, speeding up installation and reducing errors.
- • Unlimited Wind Warranty: When installed with the required GAF accessories, the Timberline HDZ carries an unprecedented "WindProven" infinite wind speed warranty (not just 130 mph).
- • Algae Tech: Their Time-Release Algae Protection is highly effective at preventing black streaks over the long term.
The Drawbacks
- • Aesthetics: While clean, the standard HDZ colors lack the high-definition "pop" and dramatic drop-shadows seen in Owens Corning's TruDefinition line.
- • Mass: Like OC, GAF has shifted toward lighter, more technologically advanced shingles rather than traditional sheer weight.
CertainTeed (Landmark)
CertainTeed has long positioned itself as the premium, heavyweight champion of the asphalt shingle industry.
What We Love
- • Heavyweight Construction: CertainTeed leans heavily on mass. Their Landmark shingle is undeniably thick and heavy, which provides excellent durability against physical impact and weathering.
- • Rich Colors: Their color blends are classically beautiful and highly sought after by homeowners doing premium custom builds.
- • Quality Control: Historically known for very rigorous quality control and remarkably low factory defect rates.
The Drawbacks
- • Nailing Zone: Their standard nailing area is narrower and less reinforced compared to OC's SureNail or GAF's StrikeZone, giving contractors a smaller margin for error.
- • Price Point: Often the most expensive option among the "Big Three" standard architectural lines.
The Final Word
You cannot go wrong with the top-tier products from any of these three manufacturers if they are installed perfectly. However, because human error is the #1 cause of roof failure in Iowa, our hosts give the slight edge to Owens Corning Duration and GAF Timberline HDZ. Their aggressively reinforced nailing zones offer an incredibly forgiving high-wind defense system that actively prevents contractor installation errors.
