The county surrounding Chelmsford averages 3.1 significant hail events per year (hail diameter ≥ 1"). High-wind events average 30.3 per year.

With 5,922 annual heating degree days, Chelmsford is in a climate where ice dams are a real seasonal hazard — attic heat escapes through the roof deck, melts snow, and the meltwater refreezes at the cold eaves, backing up under shingles and causing interior moisture damage. 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.

EPA Radon Zone 1 — Middlesex County
Middlesex 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.
