Metal roofing must be able to breathe in the same way as asphalt shingles do. Metal roofing, like other materials, requires sufficient ventilation and natural air movement provided by the structure. Proper ventilation is necessary to maintain cooler temperatures, which will aid in the prevention of condensation. Metal roofs are subject to the same ventilation requirements as other roofing materials! To learn more about metal roofing systems, contact a local roofing professional.
