Which one is right for you?
Choose Owens Corning if…
- You want the deeper Preferred/Platinum contractor bench for competing local bids rather than Malarkey's smaller Emerald Premium roster.
- Platinum Preferred Protection's 25-year component coverage outpublishes Malarkey's Emerald Premium workmanship term at a comparable tier.
- You prefer the SureNail woven-strip reinforcement at the nailing line over Malarkey's NEX laminate construction.
Choose Malarkey Roofing if…
- You're building in a cold or freeze-thaw region and want Malarkey's polymer-modified rubberized NEX asphalt, marketed specifically for low-temperature flexibility.
- You want Scotchgard Protector's lifetime-published algae resistance instead of StreakGuard's term, which varies by Owens Corning product line.
- You care about recycled-content disclosures, and Malarkey publishes shingle-specific rubber and plastic content figures that Owens Corning only reports at the corporate level.
- Picking an asphalt formulation on marketing claims alone rather than asking your roofer whether NEX's cold-weather flexibility matters for your specific roof.
- Treating Malarkey's smaller Emerald Premium contractor count as a quality signal instead of simply fewer local install options.
- Letting warranty registration lapse, which trims the extended coverage window on Platinum Preferred Protection or Emerald Premium alike.
- Assuming Highlander NEX's Class 4 rating applies to every Malarkey shingle rather than confirming it by product line.
