Flat roofs in Florida typically last between 10-25 years, depending on the specific material used. Built-up roofing (BUR) systems generally provide 15-20 years of service, while modern TPO and PVC membranes can reach the 20-25-year mark with proper care. Modified bitumen typically falls in the middle range. The shorter lifespan compared to pitched roofs stems from water pooling issues and Florida’s intense UV exposure. Regular inspections and maintenance are crucial—small issues can quickly become major problems on flat surfaces. With professional semi-annual inspections and prompt repairs, you can maximize your flat roof’s potential lifespan.
