Currently, one of the fastest growing products for use in commercial roofing is TPO (or, thermoplastic polyolefin). Throughout the roofing industry, TPO roofing membranes have many advantages, both in terms of installation and performance. As the world continues to focus on roofing systems that are energy-efficient, TPO roofing systems resist ultraviolet, ozone and chemical exposure levels in significant amounts.
TPO membranes are environmentally friendly, and their flexibility makes them highly durable and resistant to punctures. These membranes are usually laid across the roof, and then secured in one of three ways: “fully adhered” means that an adhesive is applied to the roof’s surface prior to the TPO being placed atop it; “mechanically attached” means that the TPO is secured to the roof’s surface using some type of screw; “ballasted” means that the TPO is laid across the roof’s surface before being weighted down with rocks, gravel, or similar materials. TPO roofing systems have been in use for over 10 years. TPO roofs are gaining in popularity for new construction and as the replacement roof of choice.
