Modern single-ply membranes like TPO or EPDM can last 20-30 years with proper care. Key factors include the quality of the initial installation, local climate, and consistent maintenance to address minor issues before they become major. Regular professional inspections are crucial. When repairs become frequent and extensive, a full replacement is more cost-effective.
