Commercial EPDM Flat Roofs

EPDM stands for Ethylene Propylene Diene Monomer. It is a synthetic rubber derived from oil and natural gas (ethylene propylene).

EPDM roofing  is commercial roofing material that has been used for over 40 years on low-slope roofs and is used by many companies that offer commercial roofing services. EPDM is a durable rubber membrane that protects flat or low-slope commercial buildings from water, wind, sun and other elements. EPDM is tough to be one of the best commercial roof applications available.


The true test of any product is whether it actually performs in a live environment. EPDM roofing has shown that it can handle the elements as promised and newer improvements have been made to ensure that it will only become more reliable. Commercial builders choose EPDM for a variety of reasons:

Wind resistance.
EPDM can resist wind damage and uplift. EPDM roofs can be rated to resist high winds, anywhere from 60 to 120 MPH.
Heat resistance.
These rubber roof coatings are both heat and fire resistant making them perfect for the hot, St.Louis weather.
UV radiation resistance.
EPDM is resistant to ultraviolet radiation.
Weather elements.
Hail, wind, rain, and snow are all handled well by this high endurance rubber membrane. One of the main benefits of having A EPDM roof is that there is no needed maintenance on these roofs.


EPDM roofing comes in two main types, white and black. In warmer climates, white is the most commonly used due to its energy-saving capabilities. White EPDM has a reflective, environmentally friendly surface that enhances the membranes ability to reflect UV rays. cooler climates, the black EPDM is preferred, attracting heat and reducing heating costs.


There are three main ways to install EPDM roofing: Ballasted, mechanically attached and fully adhered systems.
Mechanically attached system.
The most economical installation method is using the mechanically attached system. This method is lightweight and works well in areas without high winds.
Fully adhered systems.

Fully adhered systems are becoming the preferred type of EPDM system due to the longevity and advances in the application. The membrane is bonded to the insulation and attached in large panels. EPDM panel seams are sealed with either a liquid adhesive or specially formulated factory applied tape. The tape has made seaming easier, less labor-intensive and creates stronger seams than in the past.
