Even though flat roofs aren’t sloped like residential homes, wind speeds and uplift pressure can still damage them. Wind damage often appears on flat roof membranes in the form of frayed and damaged membrane edges. When strong winds hit a flat roof, its uplift pressure becomes greater than its speed and bears down on the roof membrane’s edges. This pressure lifts the edges, separating them from the rest of the membrane. If a roofing contractor installs the membrane improperly, the edges can get severely affected, and the membrane could eventually fly off the building.
Wind lifts the edges of roof membranes on TPO and EPDM roofs, while hail and debris cause cracks throughout these singly-ply membranes.
