These guys are fantastic! During a thaw after lots of snow, we had an ice jam that was causing water to flow into our house. I contacted Windy City Flat roof first thing on Monday morning and Eli call

never returned calls and 18 months after I spent $16k with them the roof has water pooling underneath it. Under no circumstances should you use them.

Fixed a damage area on my roof. Prompt service, quality workmanship, cleanliness, and very professional.
