Although single-ply membrane roofing systems constitute the majority of roofs installed today, the technology that has resulted in such popularity is in some instances decades old. Many materials and installation techniques were developed and refined in Europe prior to making an appearance in the U.S. marketplace.

There are three basic groups of single-ply products:

1.    Vulcanized elastomers such as ethylene propylene diene monmer (EPDM) or "rubber" and neoprene.

2.    Non-vulcanized elastomers such as chlorosulfonated polyethylene (CSPE or "Hypalon"), chlorinated polyethylene (CPE), and polyvinyl chloride (PVC).

3.    Thermoplastics such as polyvinyl chloride(PVC) and TPO.

The methods of securement of these systems range from ballasted to mechanically fastened to totally adhered. Seams can be taped, glued, heat-welded, solvent welded, and mechanically fastened to provide a strong, watertight monolithic system.

The many available options can cover a variety of requirements and Olsson Roofing is very well versed in assisting our customers in determining the appropriate system to service their needs.
