Combining high-grade asphalt with synthetic and upcycled rubber and plastic polymers, proprietary NEX® Polymer Modified (Rubberized) Asphalt formulation rubberizes the asphalt core of the shingle to deliver superior all-weather resilience and longer product life.

Windsor® Scotchgard™ shingles have up to 40% greater tear strength and 65% greater granule retention than the industry standard (ASTM D3462), carry a Class 4 hail impact rating, and meet the stringent IBHS FORTIFIED™ Roof requirements.

Recycled content can sometimes diminish product quality. Not so with our shingles. Polymers from upcycled tires and plastic bags are added to our asphalt formulation to improve shingle strength and durability, while reducing landfill waste – extending product life and landfill life.

Each average-sized roof of Windsor® Scotchgard™ shingles diverts the equivalent of ~7 tires and ~7,100 plastic bags from the landfill.¹

Eight bonds (3 laminate, 2 rain, 3 wind) of synthetic rubber adhesive resist dry-out and deliver extreme protection from high-winds, wind-driven rain, and shingle delamination.

Windsor® Scotchgard™ shingles have up to 50% more adhesive bonds, twice the rain seals, and thrice the wind seals of standard shingles.

Ceramic-coated 3M™ Roofing Granules add lasting color vibrancy, while our NEX asphalt technology dramatically enhances granule retention – the shingle’s primary defense against hail, scuffing, and the aging effects of UV sunlight.

Windsor® Scotchgard™ shingles have up to 65% greater granule retention than the industry standard specification (ASTM D3462).

3M™ Smog-Reducing Granules, which blend inconspicuously into the shingle’s color, harness sunlight to photocatalytically convert dangerous smog gases like nitrogen dioxide (NO₂) into water-soluble salt ions that rinse off the roof with rainwater, actively cleaning the air of these emission-based pollutants.

Each average-sized roof of Windsor® Scotchgard™ shingles helps fight smog air pollution equivalent to planting ~2 trees.²

Algae-resistant 3M™ Copper Granules blend inconspicuously into the shingle’s color and help prevent unsightly black streaks caused by algae growth.

Windsor® Scotchgard™ shingles feature Scotchgard™ Protector which utilizes at least 10% 3M™ Copper Granules, and come with a limited lifetime algae warranty.

At Malarkey, we strive to make shingles that don’t need warranties, but just in case, we offer standard and extended shingle warranties, or our innovative ‘Your Choice’ warranty where we’ll match a competitor’s standard warranty.³

Roofs work better when the parts work together. A complete new roof requires 5 components – shingles, underlayment, ice & water barrier, starter shingles, and hip & ridge shingles.

If your roof is installed by a Malarkey Certified Contractor, who also uses the above Malarkey accessories as a part of a complete roof system, your roof is eligible for extended warranty coverage.
