Modified Bitumen Roofing Specialists

One of the longer lasting roofing options for flat roofs is bitumen roofing or a modified bitumen roof. Modified bitumen is a type of asphalt product that can be applied in a number of ways to the roof in both hot and cold temperatures. Modified bitumen roofs have a lot of advantages over other types of membrane roofing, and are often seen as the modern alternative to the built up roof.

  •  Durable in extreme cold weather conditions we experience in Chicago
  • Repairs easily
  • Factory manufacturing ensures consistent quality control
  • Expands and contracts with movement of your building
  • Resists UV light, helping to reduce cooling costs

What Our Customers Are Saying

Ron and his crew are amazing!! I called to get a quote for our business and they came out the same day within in an hour. Once we made the decision to go with One Source Roofing they did the repairs 2 days later and then proceeded to contact me for 2 days after that when we had rain to make sure we didn't have any leaking (which there wasn't). They came back to the office to replace the ceiling tiles the following week after we were sure that they had all been fixed. They did an amazing job and everyone was very professional but friendly. I would recommend them to everyone. If I could give more than 5 stars I would. They deserve it. Excellent customer service.

Ron, It’s been a sincere pleasure working with you and your One Source Team on our various roof projects over the past 18 months. Let’s face it, we’ve pretty much faced every challenge and obstacle along the way when tearing off our big roofs last year, and then in prep for our Solar array on two warehouses this Summer. You and your team are always quick to point out the good and bad, and show us which obstacles could create the biggest challenges financially. Your sincerity and trusting ways is what makes the process works when you’re spending over 100k on a project. You’ve always delivered and never overpromised while meeting all of our expectations. Further, your followup for the smallest problems post project are incredible. Just today you had your son over to patch up a small problem that the solar installers created, and it was done quickly and without a hitch! Thank you for all the hard work!
