Roof Replacement Cost in Illinois (2027 Price Guide)
Adjust the house size or the roof slope in Illinois
A roof's pitch is its rise in inches over twelve inches of run. Steeper roofs like 9/12 need roof jacks and harness work, so they cost more. We assume 7/12 for Illinois; pick yours above.
Budget $10,440 to $15,910 to strip and re-shingle a typical 1,700 sq. ft. single-story house in Illinois with standard asphalt. We get there from roughly 20.8 squares of roof (2,083 sq. ft.) pitched at 7/12; one layer comes off, and labor plus materials are in the number.
Roofers bid by the square, which is a hundred square feet of roof; here the installed rate works out to $610.94 a square. Two common step-ups: architectural 50-year shingles at $11,600 to $17,680, and steel shingles, the entry metal, from about $22,450.
- Home: 1,700 sq. ft., 1 floor
- Under roof: 1,700 sq. ft.
- Roof surface: 2,083 sq. ft. (20.8 squares), 7/12
- 30-year asphalt: $10,440 to $15,910
- 50-year architectural: $11,600 to $17,680
- Metal: $22,450 to $46,590
- Flat (EPDM), full footprint: $14,220 to $18,470

Where the numbers come from: the roof replacement calculator for shingles, the metal roof calculator for metal and the flat roof calculator for flat membranes, each set to Great Lakes pricing - 3% above the U.S. average for shingles and metal.
Price per Year of Roof
The real cost of a roof is price divided by the years it lasts. Hover a bar: metal costs more up front and less per year.
Service lives follow the climate-bell model above (asphalt peaks in moderate regions; metal assumes correct installation); prices are the Illinois estimates above.
Reading a Illinois Roofing Quote Line by Line
A cheap bid and an expensive bid often describe two different jobs. On this 20.8-square Illinois roof, these items carry real dollars:
- Strip and haul. Expect roughly $3,050 of the bid for one layer off. Each extra layer underneath raises it again, by about $1,980 for the second.
- Hips and valleys. Take a basic gable as the baseline. A hip layout costs roughly $1,260 above it; dormers and valleys scattered across the roof cost about $2,130 above it.
- Building height. Same roof, two stories up: about $910 more, mostly labor and safety staging.
- Roof windows. Each skylight in the scope adds roughly $370 - cheaper now than as a separate job later.
- Sheathing repairs. Soft spots in the roof deck show up during tear-off. A per-sheet price in the contract keeps that from becoming an open-ended charge.
- Accessories. Ridge vents, pipe flashing and drip edge belong in the scope. If the gutters are due too, run them through the gutter cost calculator.
- Paperwork. Local permit fees and dumpster rental vary; ask each roofer to list them rather than add them later.

Figures cover the 7/12 roof above (2,083 sq. ft.) at Illinois prices; add gutters, skylights and any deck repairs separately.
Line the quotes up side by side: layers removed, underlayment type, ice-barrier coverage, flashing, ventilation and the decking price. The lowest bid often leaves one of those out.
Weather, Wear and Your Illinois Roof
Climate Region 2 on the map below covers Illinois. Average winter highs run about 35°F, overnight lows about 19°F, and summer afternoons about 87°F. Below are the stresses that matter most for a Illinois roof, and what to ask for because of them.
Ice dams. With winter lows around 19°F, eave ice is the main leak risk. Insist on ice-barrier membrane at the eaves and in every valley, then cut the attic heat loss that starts the melt. The attic insulation calculator and roof heat cable calculator cover that side.
Freeze-thaw cycles. Water that seeps into a cracked shingle or an open seam freezes at night and widens the gap. Over many winters, small openings become leaks. Ice barrier at the eaves is inexpensive protection.
Wind. Strong storm winds lift shingle edges and peel back roofing at the rakes. Ask for shingles with a high wind rating and the manufacturer's high-wind nailing pattern.
Where Shingles Live Longest: the Climate Bell
Asphalt life peaks in the moderate middle (Region 3) and falls toward BOTH ends of the map above - cold regions destroy shingles with ice dams, hot ones bake them. Note the middle columns: shingles marketed as “lifetime” are good for about 25 real-world years at best - Illinois is Region 2. Hover any column.
low pitch holds snow and ice - it costs the most years in cold regions
Planning figures from our climate model, for ventilation-correct installs - a baked, unvented attic can take years off any column. Pitch adjusts the asphalt columns only; metal sheds snow at any sane pitch.

Metal Roofing Prices in Illinois
Metal is not one product. Long panels, metal shingles, stone-coated tiles and copper each solve a different problem, and the price gap between them is wide.
- Standing seam: $29,930 to $45,620. Tall ribs, clips under the seams, nothing exposed to rust or work loose. Wide, plain roof planes show it at its best. Here it costs about $22,360 above architectural shingles.
- Steel shingles: $22,450 to $34,230. Aluminum shingles: $24,830 to $37,850. Small metal panels with a shingle or tile profile. They go on much like shingles, so hips and dormers are easier than with long panels. Pick aluminum near the ocean and steel inland.
- Stone-coated steel: $30,560 to $46,590. Steel tiles with a coat of stone granules. They are quiet in the rain, hard to dent, and look like tile or shake from the street.
- Copper: custom quote only. Copper is a craft job, so we leave it out of the calculator and you will need a custom bid. It costs the most of any metal by a wide margin. A small copper accent over a bay window gives you the look without the whole-roof bill.
Metal sheds snow fast, and that starves ice dams before they start. Less ice at the eaves means fewer leaks, less rot, and a roof that lasts decades longer than asphalt in this cold. Snow guards keep the slide away from doors.
The case for metal rests on how long you will stay. Keep the house for decades and one metal roof can replace two asphalt roofs; sell soon and the premium rarely comes back. Want a firmer metal number? Try the metal roof calculator with your measurements.

Roofing Season in Illinois
Cold winters (highs around 35°F) push most re-roofing into the warm months, when shingle seal strips can bond. Get bids in late winter to secure a spring or summer slot.
After a big storm, out-of-area crews go door to door. Before signing, confirm liability and workers' compensation insurance, a local address, and any license your state or town requires.
Pricing Low-Slope Roofs in Illinois
Porches, additions, garages and some whole houses have roofs too flat for shingles; they get a membrane. Priced on the full 1,700 sq. ft. footprint in Illinois:
- EPDM rubber: $14,220 to $18,470. Old-school rubber roofing, and still a fair choice. It takes a hailstorm and a hard freeze in stride. The dark color soaks up sun, so it fits best where nobody lives right under it.
- TPO, 60-mil: $12,240 to $15,900. A white single-ply sheet whose seams are welded with hot air into one piece. It reflects the sun and now covers most new flat roofs on homes and shops.
- PVC, 60-mil: $14,800 to $19,220. PVC is the one to pay up for when the roof works hard: a deck with chairs on it, a grill, a corner that never quite dries. Its welded seams and chemical resistance outlast the cheaper sheets there.
Price order in Illinois: TPO first, PVC last, with EPDM between them. These figures assume polyiso insulation and one layer removed. Small roofs carry a premium because setup is the same for any size. Make sure a new flat roof drains completely; trapped water and winter freezes are a bad combination. The flat roof calculator handles other membranes and insulation levels.
Snow load and slow melt are the test in Illinois. Any of the three can pass it if the seams are done right and the water has a clear path off the roof. Ask how the bid handles drains and low corners.

Before You Re-Roof in Illinois
Should my roofer get a permit in Illinois?
Usually. Permit rules are set locally, and most require one for a complete re-roof. A licensed roofer pulls it in their own name.
What does a roof square mean on a quote?
Take the footprint (1,700 sq. ft. here) and adjust for pitch (7/12): about 20.8 squares, or 2,083 sq. ft., counting overhang and waste. Get the square count on every quote.
Will a roof replacement take more than a day?
Most shingle re-roofs on a house this size (2,083 sq. ft. of roof) finish within a few working days. Extra layers, steep pitch or rain add time; metal takes longer.
Does homeowners insurance cover roof replacement?
Insurance covers storm and impact damage, not wear. A worn-out roof is a maintenance cost - here about $10,440 to $15,910 for asphalt. After a storm, take photos and have a roofer look before you open a claim. Storm deductibles in Illinois are often a percentage of coverage rather than a flat amount, so the out-of-pocket share can be large.
