Metal Retrofit Tired of your leaking roof but aren't sure what's causing the leaks? Problems Causes Metal Corrosion Rusting and corrosion of metal roofs occurs from normal precipitation and acid rain as well as ponding water.  Over time, this corrosion makes its way through the metal, leaving holes for water to penetrate Expansion and Contraction As seasons and temperatures change, leaks can occur.  As the metal roof expands and contracts fasteners loosen at the joints.  The thermal movement ends up leaving loose seams and cracks at penetrations leading to leaks in your roof. Condensation Metal roofs are difficult to seal and insulate.  Moist interior air can condense on the back side of the metal.  The condensate drips into the building, causing the same problems as leaks. Transition Areas Metal roofs are only watertight if the slope is adequate.  Transitions, valleys and interior gutters are prone to leaking with metal roofing.
