Coating systems can deliver a wide range of benefits for building owners willing to consider a pro-active approach to their roofs and sidewalls. Aside from leak protection, the fundamental benefit of asset preservation is first and foremost. Roof replacement is a costly proposition. If the roof can be preserved via a timely, quality minded coating effort, the savings can be substantial. In most instances metal roofs and single-ply membranes can be coated and preserved indefinitely. In fact, the mechanical fastening systems and glues (associated with fully adhered membranes) will likely present a greater design challenge over a 40 or 50 year time span than the preservation of the roofing material itself. Additionally, buildings that draw air from the roof or with rooftop AC units will achieve substantial energy savings when highly reflective white or pastel shades are used over black or conductive metal surfaces.
