What’s the current per-square installed price in Illinois?

For mid-tier architectural shingles in 2026, $475 to $650 per square installed in Madison County, with most jobs landing $525 to $600. That’s the all-in number including materials, labor, underlayment, basic flashing, and removal of the old roof. It does not include code upgrades, decking replacement beyond the 2 to 4 sheet allowance, or premium materials.

The variation is driven by complexity (steep slopes, multiple hips, lots of penetrations) and accessories (skylights, chimneys, gutters). A simple gable roof at 5/12 pitch quotes near the lower end; a complex roof with dormers, valleys, and 10/12 slopes quotes near the upper. Trill prices line-item so you can see what’s driving the per-square number for your specific home.
