Commercial Roofing FAQ

Get answers to some of the most frequently asked commercial roofing questions in Chicagoland.

Our experienced project managers will first identify key attributes of the existing roof such as type, age, repair history and last date of a field inspection with report. This will give you a quick assessment of your roof’s condition. Next, we’ll look for interior damage. Water stains, mold and the underside of the deck for deterioration, dry rot or rusted steel deck and cracks in concrete decks are potential indicators of severe roof damage.  Many times these problems can be solved with repair instead of replacement but there comes a time when repair is not the most cost effective option.  We will walk you through the pros and cons of repair versus replacement and provide highly detailed written estimates for each of these options.

There’s no simple answer to this question.  From EDPM to PVC to Metal and more, there are many factors including business type, structure and budget that will help us answer this more pointedly.  Our team is experienced and certified with each type of roofing system including EDPM, TPO, Modified Bitumen, Metal, PVC and Asphalt.

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!
