Below are a few of the most common commercial and industrial roofing membranes we work with:

Modified Bitumen

Developed in Europe in the early 1960’s, polymer-modified bitumen or modified bitumen (MB) sheet membranes have been used in the U.S. since the mid 1970’s. These roofing membranes are made from reinforcing fabrics that serve as carriers for the hot polymer-modified bitumen. MB membranes feature multiple layers (much like BUR membranes) and are installed as a 2-ply system. They are almost always fully adhered.

There are 2 types of modified bitumen roofing membranes:

  1. SBS polymer-modified bitumen. These roofing membranes are installed in hot-moppings of asphalt or cold adhesive. Some types contain an adhesive backing, making them self-adhering.
  2. APP polymer-modified bitumen. These roofing membranes are usually applied via torch or heat-welded.

Thermoplastic Olefin (TPO)

The absence of chemical crosslinking sets thermoplastic materials such as TPO apart from thermoset materials. Thermoplastic roofing membranes can be repeatedly softened by heating or hardened by cooling without incurring damage. Because of their chemical nature, TPO membranes are often installed via heat welding with hot air or solvent welding.

TPO membranes are made by calendaring with a variety of techniques including lamination, extrusion with lamination, or extrusion-coating. Fabricated with a blend of polypropylene and ethylene propylene polymers, TPO membranes are typically reinforced with polyester for additional strength and durability. For customization purposes and to ensure longevity, these membranes contain colorant, flame retardants, UV absorbers, and other proprietary substances.

EPDM Roof Membranes

These thermoset roofing membranes feature chemically cross-linked or vulcanized principal polymers. “Cured” vulcanized membranes can only bond to similar materials using adhesives. EPDM is the most common thermoset roofing membrane.

EPDM is primarily made up of 2 compounds, ethylene and propylene, which are derived from oil and natural gas. EPDM membranes can be installed fully adhered, mechanically attached, or ballasted. Most do not receive surfacing.
