Will County, Illinois homeowners in Mokena, New Lenox, Homer Glen, Joliet, Lockport, Plainfield, and Romeoville face different roofing cost factors than their neighbors in Cook County or Indiana. This guide gives you accurate 2025 pricing for your area.
The Short Answer for Will County
- Asphalt shingles: $10,500 – $24,000
- Metal roofing: $20,000 – $36,000
- Average Will County home: 1,700–2,400 sq ft | 19–27 roofing squares

Why Will County Costs Are Different from the National Average
National roofing cost calculators typically use an average that doesn’t reflect:
– Local labor rates: Will County labor runs slightly higher than rural Indiana markets
– Home sizes: Will County’s newer suburban developments have larger footprints and more complex rooflines
– Permit costs: Will County municipalities each have their own permit fee schedules
– Material transportation: Materials delivered to western Will County suburbs carry slightly higher delivery costs
