"Impeccable work, and the attentiveness and professionalism leading up to the work was extraordinary for a contractor (and I've dealt with many). La Roca designed and installed a TPO flat roof on my upper level and replaced my downspouts with wider ones. The roof seams are so tight and perfect it looks like a robot installed it, not humans. Everything turned out way beyond my expectations. This is a young company, but they are definitely running on all cylinders. This was a residential job in Palos Heights."
