GAF, Owens Corning, and CertainTeed are three of the best shingle brands available — and at Prairie Exteriors, we regularly compare all three brands to help Wisconsin homeowners understand the real differences in performance and warranty coverage. With more than 60 years of combined experience serving Madison, Sun Prairie, and South-Central Wisconsin, we’re in a position to give you an honest, side-by-side comparison based on what actually matters in our climate.
Each brand has its own strengths. No single brand is right for every home — and in Wisconsin, the stakes are higher than most. Between our freeze-thaw cycles, heavy snow loads, and severe summer storms, your shingle choice needs to match your home’s specific exposure. This guide breaks down what actually separates these three brands so you can make a confident, informed decision.

What is the difference between CertainTeed, GAF, and Owens Corning shingles?
The difference between CertainTeed, GAF, and Owens Corning shingles comes down to their flagship technologies, performance strengths, and design approaches — GAF leads on wind resistance, Owens Corning stands out for energy efficiency and overall quality, and CertainTeed offers the widest color selection and the highest impact rating across its standard product lines.
To be more specific: GAF’s Timberline HDZ shingles are built around Dura Grip™ Adhesive seals and StainGuard Plus™ technology, which resist wind uplift and inhibit algae growth.
Owens Corning’s Duration series features patented SureNail® technology — a woven reinforcing fabric at the nail line that delivers superior grip and wind resistance — along with a TruDefinition color platform that produces bold, consistent color.
CertainTeed’s Landmark series uses a dual-layered construction with a fiberglass mat base and an asphalt-based adhesive coating, giving it the highest impact rating available in a standard architectural shingle.
These differences play out in real ways on Wisconsin roofs. The Wisconsin State Climatology Office documents the state’s challenging continental climate — including the freeze-thaw cycles and heavy seasonal snowfall that put ongoing stress on roofing materials across South-Central Wisconsin. We factor all of this in when helping our customers choose the right product for their home.

CertainTeed Landmark vs GAF Timberline HDZ vs Owens Corning Duration: Which is more durable?
All three shingles are built to last, and each holds its own against Wisconsin’s seasonal extremes — but they achieve that durability through different engineering approaches.
The GAF Timberline HDZ uses Dura Grip™ Adhesive seals along the shingle edge, bonding shingles together to resist wind uplift. When installed with qualifying GAF accessories, it qualifies for the WindProven™ limited wind warranty with no maximum speed limitation — a real advantage in a state where severe spring and summer storm systems bring damaging straight-line winds.
The Owens Corning Duration relies on SureNail® technology, which places a tough woven fabric strip along the nailing zone. This provides up to 2.5 times better nail pull-through resistance and up to two times better delamination resistance compared to standard nailing, with wind resistance rated to 130 mph.
The CertainTeed Landmark uses dual-layer construction — two layers of asphalt-saturated fiberglass mat bonded together. This adds mass and rigidity, which holds up well through Wisconsin’s repeated temperature swings from well below zero in winter to the 90s in summer. The Landmark Pro series upgrades this further with Max Def color technology and a tougher fiberglass backing.
Winner: Tied
All three deliver comparable lifespans of 25 to 30-plus years when properly installed. At Prairie Exteriors, we help you match the right shingle to your home’s specific exposure — whether that’s wind, hail, or thermal stress — so you’re not making that call alone.

Quality of CertainTeed vs GAF vs Owens Corning shingles
When comparing quality, the factors that matter most are material construction, fire resistance, wind resistance, algae protection, and impact rating.
GAF brings Class A fire resistance, a 25-year StainGuard Plus™ algae protection warranty, and Advanced Protection Shingle Technology designed to maximize durability. Their Wide Nail Zone also makes installation more consistent, which matters because installation quality directly affects how well a shingle performs over the years.
Owens Corning matches GAF on fire resistance and wind resistance, and adds a 25-year algae resistance warranty. Their SureNail® fabric strip is one of the most independently tested innovations in the shingle category, and the Duration line carries a Class 3 impact rating — above average for a standard architectural shingle.
CertainTeed Landmark carries a Class 3 impact rating, the same as Owens Corning’s Duration. GAF’s standard Timberline HDZ does not publish a UL 2218 impact rating. For Wisconsin homeowners in areas prone to hail, this is worth weighing carefully. The trade-off is a shorter algae resistance warranty of 10 to 15 years compared to the 25-year coverage from the other two brands.
Winner: Owens Corning
Its SureNail® technology, 25-year algae resistance warranty, and consistent quality across all product lines give it the edge overall. CertainTeed’s Class 3 impact rating matches Owens Corning, but Owens Corning’s consistency across the full Duration line makes it the quality leader in this three-way comparison. Our team can walk you through which quality factors matter most for your specific home and location.

Which is more energy efficient?
Energy efficiency in roofing shingles is measured by solar reflectance and thermal emittance — how well a shingle reflects sunlight and releases absorbed heat. In Wisconsin, this matters most in summer, when a heat-absorbing roof can drive up cooling costs in older homes with limited attic insulation.
Owens Corning’s Duration COOL range includes CRRC-rated shingles with reflective granules designed to reduce cooling loads.
CertainTeed’s Landmark Solaris range includes CRRC-rated solar reflective options designed to reduce cooling loads in warmer months.
GAF holds a CRRC (Cool Roof Rating Council) rating and California Title 24 cool roofing approval across select products, though fewer of their flagship Timberline HDZ lines carry the same energy performance designations as the top Owens Corning and CertainTeed offerings.

Winner: Owens Corning
Broader energy performance recognition across its product line gives Owens Corning the edge. Wisconsin homeowners pairing new shingles with insulation upgrades may also want to explore Focus on Energy, Wisconsin’s statewide energy efficiency program, for available rebates on related home improvements. We’re happy to point you in the right direction on that front.
From Owens Corning's COOL Roof Collection to GAF's Timberline HDZ, Prairie Exteriors helps you choose the most energy-efficient shingle for your Wisconsin home. Contact us today.
What about maintenance?
All three brands require minimal maintenance, and day-to-day upkeep is broadly similar. Wisconsin conditions do introduce some specific maintenance considerations worth keeping in mind.
GAF’s StainGuard Plus™ technology releases copper over time to inhibit algae growth, reducing how often cleaning is needed to maintain curb appeal. Regular visual inspections after major weather events are still recommended.
Owens Corning’s StreakGuard™ Algae Resistance Protection blends copper-lined granules throughout the shingle surface, with 25 years of algae coverage. Occasional cleaning and post-storm inspection keep the roof performing well.
CertainTeed’s StreakFighter® technology similarly uses copper-infused granules, though with a shorter warranty coverage period of 10 to 15 years. In Wisconsin’s humid summers — conditions that promote algae growth — this shorter window is worth factoring into long-term planning.
⚖️ One Wisconsin-specific note: ice dams. Heat escaping through an inadequately insulated roof deck can melt snow that refreezes at the eaves, causing costly water damage.
No shingle brand eliminates ice dam risk on its own — that’s a ventilation and insulation issue — but all three brands perform better when installed over a proper ice and water shield, which Wisconsin building codes require in vulnerable areas. If you’re unsure whether your current setup is at risk, we can assess that as part of your roofing consultation.
Winner: Tied
All three are low-maintenance options. Owens Corning’s longer algae warranty gives it a slight edge over CertainTeed in that specific area, but day-to-day requirements are comparable across all three.
How do the costs compare?
Price is a valid consideration, but it should not be the main deciding factor when choosing between these three brands. The true value of a shingle comes from its longevity, the protection it offers, its energy performance, and the return on investment it delivers over the life of your roof.
In terms of relative positioning, GAF sits at the mid-range of the market, making it a strong option for homeowners who want solid performance without paying a premium. Owens Corning comes in at a slightly higher price point, though the gap is not significant — and the energy performance benefits and higher impact rating can offset that difference over time. CertainTeed is generally the most premium-priced of the three at the standard architectural tier, reflecting its heavier dual-layer construction.
The cost difference between all three brands is not significant enough to be a deciding factor on its own. Factors like your roof’s size, pitch, the specific product tier you select, and your location in Wisconsin will influence the final installed cost more than the brand choice alone.
At Prairie Exteriors, we provide clear, itemized quotes so you can see exactly what you’re getting for your investment — and why.
Winner: GAF
For homeowners prioritizing upfront value, GAF offers the most competitive entry point at the architectural shingle tier. That said, the premium for Owens Corning or CertainTeed is modest relative to the total cost of a roof replacement, and the performance advantages may well justify the difference depending on your priorities.

Warranty comparison
Warranties tell you a lot about how confident a manufacturer is in their product — but the coverage details matter more than the headline terms.
GAF offers a limited lifetime warranty on materials for the original homeowner, covering both materials and labor at 100% within the first 10 years. Wind resistance is covered up to 130 mph, and when installed with qualifying LayerLock accessories by a certified contractor, the WindProven™ warranty covers wind damage with no maximum speed limitation.
The Golden Pledge warranty extends workmanship coverage up to 25 years and is only available through GAF Master Elite contractors.
Owens Corning provides a limited lifetime material warranty, with a TruPROtection® Period that covers both shingles and labor — up to 50 years on select lines. Their Preferred Protection warranty, available through certified contractors, extends workmanship coverage up to 20 years. Standard wind warranty covers up to 130 mph.
CertainTeed offers a limited lifetime material warranty along with SureStart® protection covering both materials and labor from day one. Their SureStart PLUS warranty — available up to the 5-Star level through certified contractors — provides up to 50 years of non-prorated coverage including labor, tear-off, and disposal. This warranty is also transferable, which can add value at resale.
Winner: Tied
All three manufacturers offer robust lifetime warranty coverage, each with a standout feature: GAF’s WindProven™ no-speed-limit wind coverage, Owens Corning’s TruPROtection® Period, and CertainTeed’s transferable SureStart PLUS non-prorated coverage.

Which is best? Our key takeaways
GAF, Owens Corning, and CertainTeed are all excellent choices — and the best one for your home depends on what your roof needs to handle most. All three deliver durable, high-quality shingles, but each has individual strengths that may make one a better fit for your specific situation.
If energy efficiency is your top priority, Owens Corning is likely your best option. Their Duration COOL range includes CRRC-rated shingles designed to reduce cooling costs. For Wisconsin homeowners upgrading attic insulation at the same time, Owens Corning’s full roofing system approach pairs well with that investment.
If you want the best blend of quality and value, GAF is a strong contender. The Timberline HDZ delivers durability, weather resistance, and aesthetic appeal at a mid-range price point — and the WindProven™ no-speed-limit wind warranty is a standout for homeowners in exposed locations or areas prone to severe summer storms across South-Central Wisconsin.
If impact protection is your first concern, all three brands carry a Class 3, which is worth noting for Wisconsin communities that see regular hail activity. However, CertainTeed leads in color variety and offers the most transferable warranty coverage of the three.
Regular inspections after Wisconsin’s heavy snow seasons and spring hailstorms will extend the life of any of these roofs. Our team is always available to help with that, too.

FAQs
Is it safe to install new shingles over my existing roof in Wisconsin?
Installing new shingles over an existing layer is sometimes permitted, but Prairie Exteriors does not recommend it for most Wisconsin homes. Our freeze-thaw cycles and heavy snow loads can trap moisture between layers, accelerating deck deterioration. A full tear-off also lets us inspect and repair any hidden damage before your new shingles go down — protecting your warranty and your investment.
Will GAF, Owens Corning, or CertainTeed shingles hold up to Wisconsin hailstorms?
All three brands offer Class 3 shingles rated for impact resistance. At Prairie Exteriors, we can match the right impact-rated product to your location and budget.
Does mixing shingle brands during a repair void my warranty in Wisconsin?
Yes, using a different brand of shingles during a partial repair can void the warranty on your existing roof. Each manufacturer — GAF, Owens Corning, and CertainTeed — requires their own certified products to be used throughout the system. Prairie Exteriors always matches your existing product line exactly when replacing damaged sections to keep your warranty fully intact.
How does Wisconsin's climate affect how long my asphalt shingles will last?
Wisconsin’s 30 to 40 freeze-thaw cycles per season put more stress on roofing materials than most other U.S. climates. Architectural shingles from GAF, Owens Corning, and CertainTeed are rated for 25 to 30-plus years, but actual lifespan depends heavily on installation quality, attic ventilation, and maintenance. Prairie Exteriors factors all of these conditions into every project we complete across Madison and South-Central Wisconsin.
