Commercial Roofing in Chicago, IL

What Commercial Roofing Involves

Commercial roofing covers the full lifecycle of a flat or low-slope roof: inspection, repair, recover, or full tear-off and replacement. Unlike residential roofing, commercial systems are designed to shed water slowly across a large surface, so the membrane, seams, and flashing must be flawless. We work with TPO, PVC, EPDM, and modified bitumen—each with specific benefits for Chicago's climate.

TPO is our most common recommendation for cost and energy efficiency. Its white surface reflects sunlight, cutting cooling costs in summer. EPDM is a rubber membrane that handles extreme temperature swings without cracking. Modified bitumen offers multiple plies for extra puncture resistance—useful near Wrigley Field where parking lots see heavy traffic.

Every commercial roof we service starts with a thorough inspection. We check for ponding water, membrane blisters, exposed fasteners, and failed seams. We also examine the substrate for rot or decay—problems that wick moisture into the insulation and erode the deck from below. Catching these issues early means a repair instead of a full replacement.

Cost Ranges for Chicago Commercial Roofing

Commercial roofing costs in Chicago typically run $8 to $15 per square foot for a full replacement, depending on the system and deck condition. A 10,000-square-foot roof might land between $80,000 and $150,000. Repairs are far cheaper: $500 to $5,000 for small leaks or seam resealing. We provide free estimates with line-item pricing, so you know exactly what you're paying for.

Your final cost depends on the roof's size, the number of penetrations (HVAC units, vents), and whether we need a full tear-off or can overlay the existing membrane. A recover saves money and reduces landfill waste, but only works if the substrate is sound. We never recommend an overlay over rot or sag—that's a short-term fix that leads to bigger claims.

Permits in Chicago add $200 to $600 for most commercial jobs. We handle the paperwork and schedule inspections with the city, so you don't have to chase permits during business hours.

Signs You Need Commercial Roofing

Water stains on ceiling tiles, musty odors, or visible drips are obvious signs. But many issues are silent: granule loss in the gutters, membrane blisters that flake in the sun, or flashing that has peeled away from the parapet. If your roof is over 20 years old or has had multiple repairs in the last five years, it may be at end-of-life wear. We'll tell you honestly whether a repair or replacement makes more sense.

Chicago's spring thunderstorms bring hail that can spall TPO and dent metal coping. Winter's freeze-thaw cycles cause ice dams that lift seams and let water seep under the membrane. If you notice any of these, call us before the next storm turns a small leak into a structural problem.

Our Commercial Roofing Process

1. Inspection and quote: We assess the roof, take photos, and provide a written estimate within 48 hours.
2. Material selection: We walk you through TPO, EPDM, or modified bitumen options, including energy savings and lifespan.
3. Prep and tear-off (if needed): We remove the old membrane and inspect the deck for rot or decay. Any damaged insulation is replaced.
4. Installation: We lay the membrane in staggered courses, heat-weld seams, and flash all penetrations with self-adhered detail membrane. Ring-shank nails secure the base layers.
5. Quality check: We flood-test the roof to find any leaks before we leave.
6. Cleanup and warranty: We haul away all debris, provide a workmanship warranty, and register the manufacturer's warranty.

Insurance and Warranty Info

We work with your insurance adjuster for storm damage claims. We document everything with photos and provide a scope of work that meets Chicago code. Most commercial policies cover hail and wind damage; we help you file and fight for the full replacement cost.

Our workmanship warranty covers leaks for 5 years, and manufacturer warranties run 15 to 30 years depending on the membrane. We're licensed and insured, and we display our license number on every contract. That's not just paperwork—it's a promise that we're accountable for our work.

Why Chicago Roofing Team

We've served Chicago since 2005, from Lincoln Park to Bronzeville. We know how lake-effect snow loads and extreme temperature swings stress commercial roofs. We've replaced roofs on 1960s buildings in Hyde Park where the deck had rotted under old tar, and we've repaired hail damage in Logan Square where the membrane had split along every seam. That experience shows in our workmanship.

We're not the cheapest, and we're not the fastest. We're the roofing contractor Chicago property managers call back because we show up on time, communicate clearly, and fix problems the first time. If you're comparing bids, ask about our warranty and our inspection process—you'll see the difference.
