Metal Rust - Corrosion occurs when the protective coating or galvanization of the roof wears out and bare metal is exposed. |
Flashings - A majority of metal roof leaks are caused by poor flashing design along penetrations. |
Temporary Repairs - Stop using seam tapes, mastics and silicone sealants on a metal roof. They aggravate the leak! |
Seam Leaks - If you have an older metal building constructed using panels with exposed fasteners and seams. |
Annual maintenance includes patching any holes and treating any rusted areas as soon as possible. Avoid using asphalt mastics, silicone sealants and aluminum and plastic backed tapes on the seams.
