Quality Metal Roof Manufacture & Sales Inc. (Quality Metal Roofing) products are finished with a factory backed high performance pain coating. The surface of this coating has proven resistant to many environmental elements such as air pollution, acid rain, and airborne dirt. It is designed for exterior color retention and resistance to chalking.
If the need to clean or remove deposits from your coating does arise, a variety of methods for cleaning are available. Note two precautions: (1) Do not use wire, brushes, abrasives, or cleaning tools which will mechanically abrade the surface coating, and (2) Certain cleaning agents listed below should be tested in an inconspicuous area before use on a large scale. Misuse or abuse of any cleaning agents will result in voiding warranty for affected surfaces.
