Costs at a Glance
Every figure here comes from an online cost publisher, not from a bid on an actual Rockford house. Use them to set expectations and to spot a quote that seems far off. The Rockford shingle range dates from 2024, so it may trail current material and labor prices.
| Cost row | Figure | Source (year) |
|---|---|---|
| Whole roof, Illinois average | about $6,525 (typical range $5,081–$16,643) | This Old House (2026) |
| Asphalt shingles, Illinois average | about $4.70 per sq ft | This Old House (2026) |
| Asphalt shingles, Rockford | $5–$7 per sq ft | HomeBlue (2024, dated) |
| Metal, Illinois average | about $8.77 per sq ft | This Old House (2026) |
| Steel metal roofing, Chicago area | $6–$16 per sq ft | Angi (no date given) |
Apply the per-square-foot rows to your roof's surface, not to the living space listed on your tax bill. Slope and overhangs make a roof larger than the floor below it. As a quick example, 2,000 square feet of roof surface at $4.70 to $7.00 works out to roughly $9,400 to $14,000 for asphalt shingles. Roofers often price by the "square," which equals 100 square feet.
The statewide whole-roof average mixes small and large jobs from all over Illinois, so a big two-story house in Rockford can land well above it. The steel range is wide because panel style, gauge and trim all change the price.
What Adds to the Bill
Two houses on the same block can get bids thousands of dollars apart. Size and material set the starting point. The rest depends on what turns up once the old roof is open and on what the city requires.
- Size and shape. More surface means more shingles and more hours. Dormers, valleys, skylights and chimneys add cutting and flashing, so a busy roof costs more per square than a simple gable.
- Pitch. Steep roofs call for harnesses, roof jacks and a slower pace. Many older homes near downtown have tall, steep roofs, and that shows up on the labor line.
- Rockford's two-layer limit. The city's FAQ allows no more than two layers of most roofing, and only one for wood shake, slate, clay or cement. If your house already has two, the bid needs a full tear-off and disposal.
- Decking. Soft or rotted boards usually stay hidden until the shingles come off. Ask for a per-sheet price in the bid so any replacement boards are priced before work starts.
- Ice barrier. A 2018 city memo requires ice barrier on some re-roofs, such as where ice has damaged the eaves or where one was already in place. It runs from the lowest edge to at least 24 inches inside the wall line.
- Permits. Rockford requires a permit for all roofing work. Your roofer pulls it through the Building Department (425 E. State St., 779-348-7158), and applications can go through the city's online permit portal. A dumpster parked on the street needs a separate right-of-way permit from Public Works.
Historic districts add a step. Homes in a historic district need the preservation commission's approval first, and that includes Haight Village and the city's other listed districts. If your house sits in one, say so up front so the roofer can plan for the review.
Itemized Means Itemized
A lone total at the bottom of a page tells you almost nothing. Ask every roofer to split the job into parts and to quote the same scope, so you end up weighing prices rather than guessing what each one skipped. These are the lines worth lining up side by side:
- Tear-off: how many layers come off, and who hauls the debris.
- Decking: the price per sheet if boards need replacing.
- Underlayment, ice barrier, drip edge, flashing and vents, each named.
- The shingle or metal panel brand and product line.
- The permit, the final inspection and cleanup of nails and scraps.
- Warranty terms from the manufacturer and for the workmanship, in writing.
Illinois gives you an easy way to check who is bidding. State law requires each roofer to put its license number and licensed name on every bid and contract. Find both on the paper, then search the roofer on the Illinois Department of Financial and Professional Regulation (IDFPR) online license lookup. On jobs over $1,000, the contractor must also give you the "Home Repair: Know Your Consumer Rights" pamphlet and have you sign that you received it.
If one bid comes in far below the rest, compare the lines first. A low price can hide an overlay where a tear-off is needed, a skipped ice barrier, or decking left as an open-ended extra.
How Insurance Changes the Math
When hail or wind damages a roof, a homeowner's policy may pay for part of the replacement, minus your deductible. Your insurer decides what counts as covered damage, and policies differ on older roofs, so call your agent before the inspection.
- Deductible offers. Illinois bans contractors from advertising or promising to pay or rebate any part of your insurance deductible (815 ILCS 513/18(b)). A roofer who offers to "eat" or "cover" it is describing something state law forbids, so walk away.
- Claim takeovers. A roofer may inspect, photograph and price the damage and talk repairs with your insurer. The claim stays with you and your insurer, along with a licensed public adjuster if you choose to hire one (513/18(i)).
- Pressure to sign today. For a contract paid from an insurance claim, you can cancel in writing until midnight on the earlier of two days: the 5th business day after the insurer's written notice that some or all of the claim isn't covered, or the 30th business day after it receives your proof of loss (513/18(e)).
Some carriers lower premiums for impact-resistant roofs, but each company sets its own terms, and Illinois has no current state grant for them. If you are weighing Class 4 shingles or metal, ask your insurer whether the choice would change your rate before you decide.
From Range to Real Quote
Published ranges only get you part of the way. The real price depends on your roof's size, pitch, layers and decking, and someone has to see it in person. Request a free inspection and we connect you with a local roofer licensed by the Illinois Department of Financial and Professional Regulation (IDFPR), who measures the roof and writes up an itemized estimate.
