This month’s focus on metal in Roofing Contractor provides a great opportunity to look at the sustainability of one of the oldest roofing systems. Before anyone started talking about green construction, metal roofing was delivering sustainable benefits to buildings across the globe. Few construction materials are as recyclable as metal, and the total recycled content of metal roof panels is among the highest available. In terms of durability and service life, perhaps only slate and tile are in the same league.
Today’s metal roof finishes offer cool roof options in a wide variety of colors, and the standing ribs of many metal roof systems offer an easy and simple means of attaching PV and solar-thermal modules. Add in the capability to direct and store rainwater and resist fire threats, and you check all the boxes for sustainable roofing.
