How Much Does Roof Replacement Cost in Decatur?
Asphalt-shingle replacement in Decatur, Illinois runs $6,790 to $15,035 (2,000 sq ft, tear-off and underlayment included). That is the national base range scaled by Decatur's labor-and-materials index of 0.97× — 3% below what the same job costs nationally, in a county NOAA credits with 45 hail events over the last 10 years.
Decatur's 2020 census population was 70,522, though the city has seen ongoing decline. The economy anchors on large industrial and agri-processing employers: Archer Daniels Midland employs roughly 4,000 people and Caterpillar Inc. about 3,150, alongside Decatur Memorial Hospital (1,903) and Decatur Public Schools (1,752). The aging industrial building stock and steady owner-occupied housing base sustain consistent demand for commercial and residential roofing contractors.

Hail History in Decatur — and What It Means for Your Roof Budget
County-level NOAA Storm Events archives record 45 hail events near Decatur over the past decade — hail reaching 2.50″ at its peak (archive last updated 2024-05-27). Stones that size tear through shingles rather than just bruise them. With 45 events in ten years, Decatur homeowners are effectively on an insurance-replacement cycle: any bid should include Class 4 impact-resistant shingles as a line item (10–20% more upfront, often recovered through the insurer premium discount that hail counties typically unlock). Know your wind/hail deductible before the next storm hits, not the day after. Verify your own address risk at hail risk lookup.
