Best Shingles for Illinois Snow & Wind in 2026 (Roofer's Pick)
GAF, Owens Corning, CertainTeed, and Atlas — which ones actually hold up to Illinois winters.
GAF Timberline HDZ
Our most-installed shingle. The LayerLock technology gives a wide nailing zone that's harder to mess up, and the wind warranty is industry-leading at 130 mph. A strong performer in Chicagoland's variable weather.
Owens Corning Duration
SureNail technology is genuinely useful in high-wind areas. Duration shingles handle Chicagoland winters well and the color selection is solid.
CertainTeed Landmark
A proven workhorse. Landmark Pro upgrades are worth it for premium colors and a thicker profile.
Atlas StormMaster
Atlas's impact-resistant line is worth a look in hail-prone areas. The HP42 polymer reinforcement holds up.
What actually matters more
All four major brands make good shingles. The difference between a 15-year roof and a 25-year roof is almost always installation, not the brand. Get the best installer you can find — then pick the shingle that fits your color preference and budget.
