TPO Roofing Licensed & Insured Contractors – Birmingham, AL Professional Roofers




Thermoplastic polyolefin (TPO) roofing was first introduced in the early 1990's as a economical and efficient option to PVC roofing materials. TPO roofing membranes are usually used on industrial properties and flat roof structures and have achieved recognition in numerous industries due to their toughness and ease of installation. There is also a growing need for TPO roofing methods because they are energy efficient and heat-reflective, along with resistant to chemical and UV exposure.

Thermoplastic Polyolefin single-ply roofing membranes are made from a mixture of polyprophylene and ethylene-propylene polymers which are reinforced with polyester. Other fillers applied to strengthen the TPO membrane's strength and toughness include fiberglass, wollastonite, talc, metal oxy sulfate, and carbon fiber. The TPO membrane has been particularly created to have the attributes of rubber roofing along with hot-air weldable seams for a tough waterproof bond between the sheets. The TPO membrane is composed of 3 layers:


  1. TPO polymer base
  2. Polyester-reinforced fabric center (scrim)
  3. Thermoplastic polyolefin intensified top ply


TPO varies in thickness and measurements and is employed in big rolls. Installation is done either with a completely adhered, ballasted, or mechanically connected method, enabling the white membrane to stay exposed throughout the life of the roof.

Thermoplastic polyolefin roofing is developed to offer the benefits of PVC and EPDM roofing systems, but without having the additional costs and downsides.

  3. Considering that TPO membranes have just been newly launched in the industry, there are documented functionality failures and had to be called back for corrections and improvements. Credible producers have treated these issues and complied with ASTM standards.
  4. The top layer of the TPO product is laminated which can initiate vulnerabilities that can lead to degeneration, cracks, and shrinkings on the surface. TPO rolls likewise can be found in rather small width size and in several variety of thickness.



If properly installed and serviced, a TPO roofing system can supply a functional life time functionality of 10-20 years. Aspects such as the slope of the roof, kind of installation method employed, the substrate that it is used upon, geographical conditions, and regular examination and upkeep will significantly impact the sustainability of the roof. The most important aspect that will determine the sustainability of any type of roofing system, not only TPO roofs, is the right installation by a licensed roofing professional.
