EPDM vs TPO for Chicago Flat Roofs

Chicago's climate, architecture, and insurance landscape make roofing here genuinely different from working in other cities. This article walks through what Chicago property owners need to know — based on what our crews see in the field every week.

The short version: roofs in Chicago are tested twice a year — once in the depth of winter when freeze-thaw and ice dams pry flashings apart, and again in summer when straight-line winds and hail show up with little warning. A roof that handles both gets installed differently than a roof in a milder climate.

What to watch for

Look for granule loss in your gutters (sign of shingle wear), lifted or curled shingle tabs (wind damage), staining at chimney flashings (failing counter-flashing), and any visible ponding on a flat roof 48 hours after a rain (failed drainage). Catching these early is the difference between a $400 repair and a $20,000 replacement.

When to call a roofer

Call sooner than you think you need to. The cheapest roof work is preventive. We offer free inspections for replacement estimates, and our maintenance program clients get scheduled spring and fall visits that have extended roof life by 5–10 years in our experience.

If you're dealing with an active leak, stop reading and call us — that's an emergency response situation and every hour matters.
