Proper attic insulation, air sealing, and ice-and-water shield at the eaves are the primary defenses. Source: Open-Meteo ERA5 Climate Reanalysis, 2014–2023 average.

At this frequency, specifying Class 4 (UL 2218) impact-resistant shingles or standing-seam metal is a sound investment — many carriers offer 20–30% premium discounts for Class 4 roofs in high-hail counties, often paying back the upgrade within the roof's life.

EPA Radon Zone 1 — Polk County
Polk County is classified as EPA Radon Zone 1 — the highest potential for elevated indoor radon (4+ pCi/L per EPA action level). While roofing work itself does not directly affect radon, adequate attic ventilation and sealed roof penetrations help control attic air pressure, which influences soil-gas draw through the foundation. A radon test is recommended for any home in Zone 1 counties, particularly after major weatherization or re-roofing projects. Source: U.S. Environmental Protection Agency, Map of Radon Zones, 2024.
