A Chicago Roof Replacement Done the Right Way
Replacing a commercial roof is one of the biggest capital decisions a property owner makes, and in Chicago it's also one of the most consequential. The roof is what stands between a 100-degree summer swing and a sub-zero January, and it carries the snow load, the wind off the lake, and the freeze-thaw cycling that grinds down a lesser system in a few seasons. Windward Roofing & Construction has been replacing roofs across this city since 1984 out of our headquarters at 919 S Sacramento Blvd on the West Side, and after 42 years we've learned that a good replacement isn't about the cheapest membrane. It's about matching the right system to your building and installing it so it lasts. This is a family-owned business with the Kuhn name on it, and that name rides on every roof we put down.
Tear-Off or Recover: We Look Before We Recommend
The first real question on any replacement is whether to tear the old roof off down to the deck or install a new system over the existing one. A recover costs less, keeps tear-off debris out of a tight downtown alley, and gets the building dry faster. But it's only honest if the assembly underneath is sound. We core-cut the existing roof and check for trapped moisture before we say a word, because Chicago code caps a roof at two membrane layers, and recovering over wet insulation just seals the rot inside. When the field tests dry and you're at a single layer, a recover can save you real money. When it doesn't, a full tear-off is the answer, and we'll tell you that straight.
Choosing the Right System for Your Building
There's no universally best commercial roof. There's the right one for your deck, your slope, your rooftop equipment, and how long you intend to hold the property. We help you weigh the options:
- TPO and PVC. Heat-welded single-ply with reflective white surfaces that cut summer cooling load. Both handle Chicago's freeze-thaw well, and PVC adds chemical resistance for restaurant and industrial exhaust.
- EPDM. A proven rubber membrane that stays flexible in deep cold and is forgiving on roofs crowded with penetrations and equipment curbs.
- Metal. Decades of service life on the right structure, ideal for sloped roofs and buildings where longevity outweighs first cost.
- Coatings. When a roof is sound but tired, a restoration coating can buy years and defer the full capital spend.
Code Upgrades and City of Chicago Permits
A full replacement in Chicago usually triggers more than a like-for-like membrane swap. Because the city runs its own building code through the Department of Buildings rather than adopting the International Building Code as-is, a new roof often has to meet current energy requirements for insulation R-value, updated edge-metal securement to resist wind uplift off Lake Michigan, and present-day fire ratings. We design the new assembly to satisfy those provisions, pull the permit, and coordinate the inspections so nothing stalls the job. You don't get a surprise correction notice after the crew has rolled off.
Keeping Your Operations Running
Most of the buildings we re-roof can't simply shut down, and they don't have to. We phase the work in sections, keep the building watertight overnight, and schedule the loud or disruptive stages around your hours, your tenants, and your shifts. Downtown, that means coordinating crane picks, street permits, and freight access so a hotel or office tower keeps operating. On the South Side and out by O'Hare, it means working around shipping schedules and production lines so a warehouse or plant never goes dark. We've replaced roofs over occupied offices, running production floors, and open retail without putting anyone out.
Warranties and Capital Planning
Because our crews are manufacturer-certified, we install systems that qualify for full manufacturer-backed warranties, the kind that cover material and workmanship for 20 years or more, not the thin paper a non-certified installer can offer. For owners and property managers planning capital budgets, we'll walk the roof, give you an honest read on remaining service life, and help you decide whether this is a replace-now or a coat-and-defer year. If a repair will get you another few seasons, we'll say so.

Frequently Asked Questions
It depends on what's under the membrane. A recover saves money and keeps debris off the street, but Chicago code limits a roof to two membrane layers, and if your insulation is wet or the deck is compromised a recover just buries the problem. We core-cut the existing assembly and check the moisture before we recommend anything. If the field is dry and you're at a single layer, a recover can be the smart call. If not, a full tear-off down to the deck is the honest answer.
There's no single best system, only the right one for your building and your goals. TPO and PVC reflect heat and handle Chicago's freeze-thaw well, EPDM holds up in cold and is forgiving on roofs with lots of penetrations, metal lasts decades on the right structure, and coatings can extend a sound roof you're not ready to replace. We walk your roof, factor in the deck, the slope, the rooftop equipment, and how long you plan to hold the building, then recommend the system that fits.
In almost every case, no. We phase the work section by section, keep the building dry overnight, schedule loud or disruptive stages around your operating hours, and coordinate access and street logistics so a downtown or industrial property keeps running. We've replaced roofs over occupied offices, working plants, and tenant retail without shutting anyone down.
Often yes. Chicago runs its own building code through the Department of Buildings, and a full replacement can trigger added insulation for energy compliance, updated edge-metal securement for wind, and current fire-rating requirements. We design the new assembly to meet those provisions, pull the permit, and coordinate the inspections so the finished roof passes the first time.
