PolyMod shingles is a common shorthand search term for polymer-modified asphalt shingles. For Malarkey products, the official term is NEX® Polymer Modified (Rubberized) Asphalt. The company modifies asphalt with rubber and plastic polymers rather than relying only on conventional oxidized asphalt. The intent is to produce a shingle core that stays more flexible and holds granules more effectively through weathering.
Why “polymer modified” matters
Asphalt provides waterproofing and weathering characteristics, but standard oxidized asphalt becomes harder as it ages. Polymer modification changes the material properties. Malarkey describes NEX® as rubberizing the asphalt core for improved flexibility, all-weather resilience, impact resistance and granule adhesion.
Are “PolyMod shingles” an official Malarkey product name?
Homeowners and contractors may shorten polymer-modified asphalt to “PolyMod,” “poly mod,” or “poly-mod.” Malarkey’s official terminology is NEX® Polymer Modified (Rubberized) Asphalt. Faith Home Improvement will use the current manufacturer product name in written specifications so the homeowner can compare the proposal to Malarkey’s literature.
Which Malarkey shingles use NEX®?
Other Malarkey features that work with the asphalt core
The shingle is more than the asphalt. Malarkey also emphasizes rubberized adhesive bonds, roofing granules, smog-reducing granules, impact-resistance design and accessory components. The exact combination varies by product line, which is why a product-specific comparison is more useful than a broad “rubberized shingle” label.
