The Short Answer
For most single-family homes in Chicago and the surrounding suburbs, a full roof replacement typically costs between $8,000 and $25,000. The average homeowner pays around $12,000 to $16,000 for a standard asphalt shingle roof on a 1,500–2,000 sq ft home.
That's a wide range because every roof is different. The final price depends on your roof's size, pitch, the materials you choose, how many layers need to be torn off, and whether there's any underlying damage to the decking. Here's what drives those numbers.
Average Roof Replacement Costs by Material
| Roofing Material | Cost Per Sq Ft (Installed) | Average Total Cost | Lifespan |
|---|---|---|---|
| 3-Tab Asphalt Shingles | $3.50 – $5.50 | $7,000 – $11,000 | 15–20 years |
| Architectural Shingles | $4.50 – $7.00 | $9,000 – $14,000 | 25–30 years |
| Metal Roofing | $7.00 – $14.00 | $14,000 – $28,000 | 40–70 years |
| TPO (Flat Roof) | $5.50 – $9.00 | $8,000 – $18,000 | 20–30 years |
| Modified Bitumen (Flat) | $4.00 – $7.50 | $6,000 – $15,000 | 15–20 years |
| Wood Shake | $8.00 – $14.00 | $16,000 – $28,000 | 25–30 years |
| Slate | $15.00 – $30.00 | $30,000 – $60,000 | 75–100+ years |
Most Chicago homeowners go with architectural shingles — they offer the best balance of durability, appearance, and cost. For commercial properties and flat roofs, TPO has become the go-to choice due to its energy efficiency and longevity.
What Factors Affect Your Roof Replacement Cost?
1. Roof Size and Complexity
A simple ranch-style home with a basic gable roof is going to cost significantly less than a multi-story Victorian with dormers, valleys, and steep pitches. More complexity means more labor hours, more cuts, and more flashing work around penetrations.
2. Tear-Off and Disposal
If your existing roof has one layer of shingles, the tear-off is straightforward. If there are two or three layers (common in older Chicago homes), that's more labor and more dumpster fees. Illinois building code limits you to two layers of asphalt shingles before a full tear-off is required.
3. Decking Condition
Once the old shingles come off, we inspect the plywood decking underneath. Rotted or water-damaged decking needs to be replaced before new roofing goes on. This can add $1,000 to $3,000+ depending on how much needs replacement. We won't know the full extent until tear-off day.
4. Ventilation and Insulation
Proper attic ventilation extends your roof's life significantly. If your home doesn't have adequate ridge vents, soffit vents, or attic ventilation, adding these during the replacement is a smart investment that prevents premature shingle failure.
5. Chicago Weather
Our freeze-thaw cycles, summer storms, and occasional hail are tough on roofs. That's why we recommend ice and water shield along eaves and valleys, and quality synthetic underlayment like VB Shield across the entire deck. These upgrades add a few hundred dollars but prevent thousands in future damage.
Does Insurance Cover Roof Replacement?
If your roof was damaged by a storm — hail, wind, falling debris — your homeowner's insurance likely covers part or all of the replacement cost. The key is having a proper inspection and documentation before filing the claim.
At GSKI Construction, we work directly with your insurance company to handle the claim process. We document all damage, meet with the adjuster on-site, and make sure you get the coverage you deserve. Many of our clients have had their entire roof replacement covered by insurance with only their deductible out of pocket.

How to Save Money on Your Roof Replacement
Get multiple quotes — but don't just go with the cheapest. Ask about warranties, insurance, and whether they'll handle permits. The lowest bid often means corners being cut.
Time it right — late fall and early spring are slower seasons for roofers in Chicago. You may be able to negotiate better pricing during these off-peak months.
Check your insurance first — before paying out of pocket, have a professional inspect for storm damage. You might be eligible for an insurance-covered replacement.
Don't delay — a small leak today becomes a $10,000 decking replacement tomorrow. Addressing roof issues early always costs less than waiting.
