EPDM roofs are another flat roof system that is distinguished as being composed of rubber. These rubber roofs adhere to the top of the roof. Yet another type of roof is known as SPF or Spray Polyurethane Foam.
During installation, special polyurethane foam is sprayed on the surface of the roof and then coated with some type of waterproofing elastomeric topcoat. PVC and TPO are single layers of material that are usually white or grey. These membranes can either be adhered like EPDM or mechanically attached with screws and plates.
