We spoke with Radek about roofing job in Burlington, he explained process from start to finish and answered all of our questions and concerns. The Dempsey roofing crew came out and stripped and installed new roof professionally and cleaned jobsite to a pristine condition. I would recommend Radek and his crew to all.
