Video Blog: EPDM: Standard Installation Procedures

Ethylene propylene diene monomer (EPDM) is a type of synthetic rubber that has become a popular roofing option for commercial properties. This low-cost and durable roofing option can be installed using several different methods.

In the following video, roofing and siding contractor Universal Roofing & Exteriors shares an overview of these installation methods.

Fully Adhered Installation

EPDM is manufactured and delivered as rolls of roofing material, installed over insulation and substrate. The fully adhered installation method involves the use of water- or solvent-based adhesives, much like how wallpaper is installed. This method leaves no air gaps after the adhesive has cured. Fully adhered EPDM roofs generally provide better performance against high winds, foot traffic and impact from hail and airborne debris. A skilled commercial roofing contractor should make allowances for the difference in expansion and contraction rates between EPDM and substrate layers.

Mechanically Fastened Installation

Mechanically fastened EPDM roofing is the most popular method of installation among commercial property owners because it’s faster and thus less costly. Manufacturer-approved mechanical fasteners are used for installation, with narrow batten strips serving as both reinforcement and a guide for the fasteners. The seams may require welding or adhesives.

Mechanical fasteners eliminate the need for curing, therefore, a mechanically fastened EPDM roof is ready to go right after installation. EPDM can be installed loosely to allow for differences in expansion and contraction. While the loose parts do tend to flutter in the wind, properly installed fasteners prevent the EPDM layer from being torn.

Loose-Laid Installation

While not discussed in the video, EPDM can also be installed loosely laid. With this installation method, the EPDM layer is secured only at the roofing perimeter and at areas that require flashing, such as vent pipes. The seams are also welded or adhered, while most other areas are weighted or ballasted using smooth stones or concrete pavers. Loose-laid EPDM is ideal for situations where installation time is critical, such as during roofing emergencies. It should be noted that loosely-laid single-ply roofing is not recommended for roofs with significant foot traffic.
