Technology has advanced to the point where modern metal finishes not only offer aesthetic value, but they also protect the roof panels from moisture and pollution.
The success of a metal roof system depends on its ability to resist rust and corrosion. Rust and corrosion compromise a metal roof’s waterproofing ability, detracts from its physical appearance and reduces its service life. Technology has advanced to the point where modern metal finishes not only offer aesthetic value, they also protect the roof panels from moisture and pollution. There has also been advancement in the formulations of paints and coatings used in the maintenance of metal panels. These coatings can extend a metal roof’s service life.
Metal panel finishes must be durable enough to withstand peeling, cracking, and discoloring for a reasonable period of time. The finishes must also provide superior fade resistance, particularly in areas with large concentrations of sun and continual ultraviolet exposure. UV radiation can be especially destructive to metal panels, chiefly on darker colors such as red and blue.
