Metal roofing is a low maintenance alternative to asphalt panels. The panels are lightweight, making it easier to install them.
Another benefit to metal roofing panels is that they are not affected by mildew, fungus, or moss. There is no risk of termite or rodent infestations.
Metal roofing panels do not crack, leak, split, or chip like asphalt roofs often do.
These are some of the many reasons that people use metal for their pole building roofs.
