There are 3 main types of flat roof systems found in Miami and Broward. The first are called "Hot mop" systems or BUR systems (stands for built up roofing). Layers of roofing felts are coated with hot tar or hot asphalt and finally covered with some type of gravel or stone. The final layer of the bur roofing system assists with protecting the flat roof from the sun and makes it more durable.

The second type of flat roof is a modified built-up roof called a modified bitumen roof system. Modified bitumen roofing systems use a base sheet with layers of asphalt (modified bitumen) that use fiberglass or polyester as reinforcement. A final mineral layer is added for wear and tear. These roofing systems are great at resisting the extreme temperatures found in the south Florida region.

The third type of flat roof is a TPO roof or EPDM roof. Known as single ply roofing systems, these are waterproof membranes that come in rolls and are adhered using mechanical attachment or an adhesive to the roof surface. TPO roofing systems are lightweight and energy efficient reflecting ultraviolet light saving on energy costs. Single ply membranes are also easier to install and are the best of the flat roofing solutions especially when they are tapered and insulated.
