Commercial Single-Ply Roofing

Single-ply membranes are generally categorized as either thermoplastic or thermoset. Thermoplastic materials can be repeatedly softened when heated and hardened when cooled. Thermoset materials solidify, or “set,” irreversibly after heating. Single ply membranes commonly are referred to by their chemical acronyms, such as ethylene propylene diene terpolymer (EPDM).

Single-ply membranes may contain reinforcement layers. Common reinforcements for single ply membranes include polyester fabrics or scrims, glass fiber, or a felt or fleece backing. A finished sheet’s thickness typically is referred to as mil thickness; 1 mil equals 0.001 inch. Common mil thicknesses for these sheet membranes range from 30 mils to 60 mils. Single-ply membranes can be installed fully adhered, mechanically attached or held down with ballast. Most single-ply roof systems do not receive surfacing.

In many instances, a combination of attachment methods are us

PVC Roofing

Poly Vinyl Carbonate

These systems are among the easiest single-ply roofing membranes to install and heat-weld together.

  • These systems are able to resist various chemical effluents.
  • They provide superior resistance to punctures and tears.
  • PVC systems are especially suited for roofs that are exposed to concentrations of grease, oils and many kinds of fuels.
  • In areas where acid rain or other forms of acidic outflow is a problem, PVC roofs are the preferred solution.

What is PVC roofing? Made from polyvinyl chloride (or in layman’s terms, plastic), PVC is a great single-ply roofing solution. It’s made from a lower percentage of oil and petroleum than thermoplastic polyolefin (TPO) or ethylene propylene diene terpolymer (EPDM). As a cool roof membrane, it carries both Energy Star and Cool Roof ratings.

Properly installed EPDM roofs last between 22 and 35 years before minor repair work is needed, and usually last for up to 40, even 50 years. It is widely known as the “forever roof” of the flat roofing world.

Important to know that EPDM manufacturer warranties will cover both labor and material costs, however, every job must be inspected by the manufacturer and the work done by a certified installer AND installed to spec.

EPDM Roofing

Ethlyene Propylene Diene Terpolymer

  • This system is a black single-ply membrane, often referred to as “rubber roofing.”
  • EPDM systems require minimal maintenance and are resistant to UV radiation and ozone.
  • EPDM technology has proven effective for more than 40 years.
  • It withstands temperature extremes and expands and contracts with the building.

EPDM Waterproof Membrane is a non-reinforced cured single-ply EPDM waterproofing/Roofing Membrane. The rubber film is made of synthetic EPDM rubber. EPDM rubber film is a single-layer film that can be used for a variety of applications such as waterproofing of basements, roofs/terraces, expansion joints, wet areas (toilet seats), facades, etc. It is a single product that can be used to waterproof most parts of a building.

EPDM rubber waterproofing membranes are much better technically and commercially than alternatives such as asphalt membranes, crystalline products, admixtures, various coatings, etc. These products can be avoided in projects using EPDM rubber films. EPDM waterproofing membranes are an excellent alternative to flare-type waterproofing membranes.
