Flat roof repair and re-roofing is a much different project than a standard pitched roof. Since rain doesn’t run down the side of a flat roof, flat roofs require a much more effective roof covering. Metropolitan Roofing specializes in TPO and PVC flat roofs. Both materials offer a weather-resistant and waterproof seal.
TPO Flat Roofing
Thermoplastic Poly-Olefin (TPO) is a single-ply roofing system. This roofing material can be fully adhered, mechanically fastened, or ballasted. TPO seam strengths are reported to be three to four times higher than EPDM roofing systems. This is a popular choice for green builders as there are no plasticizers added, and TPO does not degrade under UV radiation.
PVC Flat Roofing
Polyvinyl Chloride (PVC) membrane roofing is also known as vinyl roofing. Its heat-welded seams form a permanent, watertight bond that is stronger than the membrane itself. Vinyl roofing provides an energy-efficient option due to its inherently light coloring. While the surface of a black roof can increase temperatures of as much as 90º under the heat of the full sun, a white reflective roof typically increases only 10-25º.
