Single-ply roofing is classified as flexible sheets of compounded plastic-derived material that are used to cover and
protect flat and low-sloped buildings. These prefabricated membranes are manufactured in a factory to strict
quality control requirements and can be attached in a variety of methods. In the last 30 years, single-ply roofing has
displaced older materials, such as tar paper, as the go-to roofing material for commercial roofing contractors.
Properly installed, single-ply roofing systems offer an inherent advantage over traditional materials due to their
strength, flexibility, and high durability.
There are four primary methods for installing single-ply roofing systems:
The Mechanically Attached System: This system fastens the flat roofing in place by first fixing mounting plates
through the insulation to the roof deck, laying the membrane in place, and then attaching it to the underlying
The Fully Adhered System: This system can be used in roofs that have a little bit of slope to them. The mounting
plates are used to anchor the roof insulation to the roof deck and then the single-ply roofing is bonded directly to
Induction-Welded Roof Installation: When mechanical attachment is not possible, an induction-welded roof system
can decrease the amount of penetrating fasteners by up to 50 percent.
The Ballasted System: This system provides fast coverage at minimal cost. It utilizes large panels of rubber roofing
membrane, up to 50 feet by 200 feet, loose-laid on the insulation and then covered by approved ballast, such as
There are three main types of single-ply roofs:
PVC membrane roofs have been in use for decades. They are time tested and still a popular roofing system. For
many years, EPDM roofing had been the top choice for single-ply roofing. However, TPO roofing is considered the
gold standard of roofing materials.

Single-ply roofing is classified as flexible sheets of compounded plastic-derived material that are used to cover and protect flat and low-sloped buildings.
TPO is the fastest-growing commercial membrane roofing system around and is on the forefront of single-ply roofing technology.
For over 50 years, EPDM has continued to be one of the most frequently used roofing materials on the market. Architects, consultants, and engineers continue to specify EPDM as a high-performance and energy-efficient roofing system.
Whether you and your business care about a triple bottom line (people, planet, and profits) or just a single bottom line, thermoplastic polyvinyl chloride (PVC) is a roofing membrane infused with benefits.
Modified bitumen is a very durable product, especially in high-traffic areas and when confined to smaller roof areas with a high density of service equipment.
For years, low-slope metal roofing has been a favorite roof covering for commercial and industrial buildings because of its reliability against weather conditions.
