Selecting the right metal finish can help protect roof panels from rust, moisture and corrosion.
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.
