Solar panels on rooftops, something we see more and more of, offer energy solutions, but also attract and reflect heat and light that can cause blisters on built-up roofs, and warping on EPDM (rubber) roofs. Another issue or concern we often see on rubber roofs, is the moving of rock (which is the ballast that holds the roof in place) during the installation of solar panels. Without that weight in all the right places, the insulation can heave, potentially ripping seams and exposing insulation and roof decking. Many of these solar panels are installed using six-inch stanchions with very little weight (rock) put back around them. And there’s always the risk of unintended punctures during installation. These are just some of the reasons it’s important to involve a commercial roofing contractor before and after panels are installed on a rooftop. They can often make suggestions for paver systems or plant materials to help address some of these problems. And, of course, regular preventative maintenance will help keep your green initiatives from making you see red.
