While both Malarkey Legacy and Vista shingles share the same core NEX rubberized polymer-modified asphalt technology, a Class 4 impact rating, and an oversized "The Zone" nailing area, they occupy different performance tiers. Legacy shingles are roughly 19% thicker, possess greater tear strength, feature a longer standard non-prorated warranty period (20 years vs. 15 years for Vista), and integrate lifetime 3M Scotchgard protection, whereas Vista utilizes standard algae-resistant granules.
