What is the difference between Owens Corning and Malarkey shingles?
The difference between Owens Corning and Malarkey shingles is primarily in their asphalt technology and sustainability approach. Owens Corning is a global building materials leader known for its patented SureNail® Technology and vibrant TruDefinition® color platform, while Malarkey is a family-owned manufacturer that uses polymer-modified (rubberized) asphalt with upcycled rubber and plastic.
This makes Malarkey one of the more environmentally advanced shingle brands available today.
Owens Corning offers a broad product range spanning entry-level through premium architectural shingles. Their Oakridge® series is a popular mid-range architectural option, while the TruDefinition® Duration® series is their flagship line, featuring a woven reinforcing fabric strip in the nailing zone that delivers outstanding grip, wind resistance, and a cleaner installation process.
Malarkey’s NEX® Polymer Modified Asphalt technology, used across their architectural and designer lines, incorporates upcycled rubber and plastic polymers directly into the shingle’s core. This produces a more flexible, impact-resistant product that handles Wisconsin’s freeze-thaw cycles particularly well.
Several Malarkey product lines also include 3M™ smog-reducing granules — a sustainability feature no other major shingle brand currently offers.

Durability: How do Owens Corning and Malarkey shingles hold up?
When it comes to durability in Wisconsin’s climate, both brands perform well, but they get there differently.
Owens Corning offers two main architectural tiers relevant to most homeowners. The Oakridge® series is a dependable laminate shingle built for long-term performance, featuring a strong fiberglass base and StreakGuard™ algae resistance.
The TruDefinition® Duration® series steps up with SureNail® Technology — a tough woven fabric strip in the nailing area that improves holding power and wind resistance through triple-layer construction. For maximum impact protection, the Duration® STORM offers a Class 4 impact rating, worth considering given the hail events that regularly affect the Madison and Sun Prairie area.
Malarkey’s durability story is rooted in their NEX® Polymer Modified Asphalt, used across the Highlander® NEX® AR, Vista® AR, and Legacy® architectural lines. Standard asphalt becomes brittle in extreme cold; Malarkey’s polymer-modified core stays more pliable through temperature swings.
That matters in Wisconsin, where the Wisconsin State Climatology Office records Madison averaging 51.8 inches of snowfall per season, and the EPA’s freeze-thaw conditions indicator documents the significant freeze-thaw cycling that characterizes Wisconsin’s seasonal climate. Repeated contraction and expansion is one of the leading causes of shingle cracking over time, and Malarkey’s flexible core directly addresses that.
Winner: Malarkey, for Wisconsin specifically
Malarkey’s polymer-modified asphalt gives it a meaningful advantage in cold-climate performance that standard asphalt products cannot match. At Prairie Exteriors, this is one of the first things we discuss with homeowners who are weighing up these two brands for a Wisconsin roof.
Quality: Which brand builds a better shingle?
Quality in a roofing shingle comes down to material construction, wind resistance, fire rating, impact protection, and algae resistance. These are the factors that directly affect how long your roof performs without problems.
Owens Corning maintains strong quality standards across its range. Both Oakridge® and Duration® lines carry a Class A fire rating and 130 mph wind resistance, and the Duration® series adds SureNail® Technology along with a 25-year algae resistance warranty.
Their premium lines — including Duration® STORM and Duration® FLEX® — offer Class 4 impact resistance. Research from the Insurance Institute for Business & Home Safety confirms that polymer-modified asphalt shingles outperform traditional Class 4 products across most impact test categories.
Malarkey brings Class 4 impact resistance as a standard feature across their Highlander® NEX® AR, Vista® AR, and Legacy® architectural lines — not as a premium upgrade. Their NEX® polymer-modified asphalt produces a denser, heavier shingle with superior granule adhesion.
The Zone® Nailing Area also provides a larger, more accurate target for contractors, reducing installation errors that can compromise long-term performance.
Winner: Malarkey
Malarkey’s Class 4 rating as a standard, combined with polymer-modified asphalt construction, gives it a quality edge that is particularly relevant in Wisconsin’s hail season. We can help you assess which specific product line within each brand best fits your home and budget.

Energy efficiency: Which brand is greener?
Both Owens Corning and Malarkey offer cool roofing options rated through the Cool Roof Rating Council (CRRC), the recognized third-party program for independently verifying solar reflectance and thermal emittance in roofing products, referenced in building codes, LEED, and Green Globes.
One thing worth being upfront about for Wisconsin homeowners: cool roofing delivers the most meaningful energy savings in cooling-dominated climates, and Wisconsin is a heating-dominated climate. Where it does add local value is in reducing heat gain during Wisconsin’s warm summers and contributing to urban heat island reduction in areas like Madison and Sun Prairie.
Owens Corning’s Duration® COOL and Duration® COOL Plus lines carry CRRC ratings for solar reflectance and comply with California Title 24 cool roofing standards. Their TruDefinition® color platform also includes solar reflective color options across the Duration® lineup.
Malarkey goes further on the environmental side, with several product lines incorporating 3M™ Smog-Reducing Granules that actively convert smog gases into harmless water-soluble compounds, reducing air pollution beyond the roof itself. Solar reflective color options across their range also carry CRRC ratings.
Winner: Malarkey
Malarkey’s 3M™ smog-reducing granule technology is a differentiator no other major shingle brand currently matches. For Wisconsin homeowners, the sustainability case for Malarkey is stronger than the energy savings one, and we are happy to walk you through what that means practically for your project.
Maintenance: How much upkeep do these shingles need?
Both brands are engineered to minimize maintenance requirements, with neither demanding anything beyond periodic inspections and occasional cleaning.
Owens Corning uses StreakGuard™ algae resistance on Oakridge® and copper-lined granules on Duration® lines to inhibit blue-green algae growth. This is backed by a 25-year algae resistance warranty on Duration® lines.
Malarkey uses 3M™ Copper Granules for algae resistance alongside 3M™ Smog-Reducing Granules that reduce the organic buildup algae and moss feed on, giving the roof surface a proactive layer of protection. The Zone® Nailing Area also benefits long-term maintenance indirectly, as shingles installed with greater precision are less likely to develop wind-related lifting or separation issues.
The Wisconsin Department of Safety and Professional Services provides guidance on licensed contractor standards for roofing work in Wisconsin.
Winner: Tied
Both brands are low-maintenance by design, and the difference in granule technology is not significant enough to separate them here. Our team can advise on the right maintenance schedule for whichever product you choose, based on your roof’s specific exposure and age.
Price: Which brand offers better value?
Cost is a real consideration, and the two brands sit at different points in the market. Owens Corning covers a wider price spectrum, with the Oakridge® series in the accessible mid-range and the Duration® series in the upper-mid tier, making it a practical option for homeowners working with a defined budget.
Malarkey shingles carry a higher material cost across their range, reflecting the polymer-modified asphalt composition, 3M™ granule technology, and standard Class 4 impact ratings. That said, price should not be the primary deciding factor — the relevant question is total value over the roof’s lifespan, accounting for Wisconsin winter performance, potential insurance savings from Class 4 ratings, and long-term durability.
Winner: Owens Corning
On upfront material cost, Owens Corning is typically the more accessible option, particularly through the Oakridge® line. We will always help you weigh that upfront difference against the long-term performance picture before you commit to a product.

Warranty: Which brand backs its product better?
Both brands offer limited lifetime warranties on their architectural shingle lines, with non-prorated coverage periods that provide the strongest protection in the early years of ownership.
Owens Corning’s TruPROtection® Period provides non-prorated coverage for materials and labor, reaching up to 50 years on qualifying system installs across Oakridge® and Duration® lines. Unlocking the highest coverage tiers requires installation by an Owens Corning Preferred Contractor.
Malarkey’s Right Start™ Period provides non-prorated coverage for 7 to 15 years, depending on the product line, with the higher end applying to premium architectural lines installed under an Emerald Pro or Emerald Premium warranty program. Beyond the Right Start™ Period, coverage transitions to prorated for the remaining lifetime of the shingle.
Both warranties are transferable to a subsequent homeowner during the qualifying period, a meaningful selling point if you plan to sell your home.
Winner: Owens Corning
Owens Corning’s TruPROtection® Period is longer and the system warranty reaches up to 50 years on qualifying installs, providing broader non-prorated protection than Malarkey’s Right Start™ program. We can confirm exactly which warranty tier applies to your project before any work begins.
Is Owens Corning or Malarkey the better shingle for Wisconsin homes?
Both are strong products, and the right choice depends on what matters most to you. Here is how we frame the decision for Wisconsin homeowners:
Choose Malarkey if:
- Impact resistance is a top priority — Class 4 is standard across their architectural range, not an upgrade
- You want a shingle built with cold-climate flexibility in the core material, designed to handle repeated freeze-thaw cycling
- Sustainability matters to you — Malarkey’s use of upcycled materials and smog-reducing granules is genuinely differentiated in this market
- Your area has seen repeated hail events, and you want the strongest possible granule adhesion and surface protection
Choose Owens Corning if:
- Budget is a key consideration — the Oakridge® line offers dependable quality at an accessible price point
- A longer non-prorated warranty period is your priority
- You are replacing a roof after storm damage and want broad product availability and fast material sourcing
- You want a step up in aesthetics and performance without a significant premium — the Duration® series delivers that
What matters equally alongside product choice is installation quality, because even the best shingle underperforms when it is not put down correctly. That is where having the right contractor in your corner makes the difference.

Frequently asked questions
Is it okay to mix Owens Corning and Malarkey shingles on the same roof?
No — mixing Owens Corning and Malarkey products on the same roof is not recommended. Both manufacturers engineer their shingles, starter strips, ridge caps, and underlayments to work as a matched system, and combining brands can void warranty coverage and compromise performance at joints and transitions.
Using components from a single manufacturer ensures the system performs as tested and keeps your warranty intact. At Prairie Exteriors, we always confirm full system compatibility before any install begins.
Do I need a certified contractor to get the full warranty on Owens Corning or Malarkey shingles?
Yes — both Owens Corning and Malarkey require installation by a certified contractor to unlock their highest warranty tiers. A base limited lifetime warranty still applies without certification, but the non-prorated labor and material coverage periods will be shorter, which affects your protection in the early years of ownership.
Always confirm your contractor’s certification status before signing. Prairie Exteriors can walk you through exactly which warranty tier applies to your project before work begins.
How well do Owens Corning and Malarkey shingles handle Madison's heavy snow loads?
Both Owens Corning and Malarkey shingles are rated to handle the snow loads typical of Madison winters when installed over a properly engineered roof deck. Madison averages 51.8 inches of snowfall per season, according to the Wisconsin State Climatology Office, but ice dam formation at the eaves is the more common concern in our region.
Ice dams are largely a ventilation and insulation issue rather than a shingle issue — something Prairie Exteriors always assesses as part of any roofing project in the Madison and Sun Prairie area.
Can choosing an impact-resistant shingle lower my homeowner's insurance in Wisconsin?
Class 4 impact-resistant shingles may qualify Wisconsin homeowners for a premium discount, depending on the insurer and policy. Malarkey’s Class 4 rating is standard across their architectural range; Owens Corning offers it on select lines such as Duration® STORM. Availability and discount amounts vary by provider.
We recommend contacting your insurer before your roof replacement to confirm whether a Class 4 upgrade would produce savings that offset any additional material cost. Prairie Exteriors can provide product documentation to support your inquiry.
How long do asphalt shingles last on a Wisconsin roof?
A quality architectural shingle roof, properly installed and maintained, typically lasts 25 to 30 years in Wisconsin’s climate. Harsh winters, freeze-thaw cycling, and summer UV exposure all accelerate aging compared to milder regions, according to guidance from the Wisconsin Department of Safety and Professional Services.
