Best Months to Schedule Roof replacement & repair in Illinois
Derived from NOAA climate normals for IL: heating/cooling degree days, freeze months, and annual precipitation.
Why these months
Mixed-season weather (39" annual rain, 4 freeze months) means shoulder months avoid summer storms and winter freeze-thaw on flashing.
