EPDM Rubber Roofing & TPO Roofing Systems
Frequently Asked Questions
What is EPDM rubber roofing?
EPDM is an elastomeric compound that is manufactured from ethylene, propylene, and a small amount of diene monomer. These ingredients are synthesized to produce a product that exhibits a high degree of ozone, ultraviolet, weathering and abrasion resistance, and outstanding low temperature flexibility. These ingredients also contribute to resistance to acids, alkalis, and oxygenated solvents (i. e. , ketones, esters, and alcohols).
What does EPDM rubber roofing look like?
Black EPDM has a smooth surface similar to natural gray slate and does not contain surface granules that can eventually be lost on other materials. White EPDM also has a smooth surface, but is white. It combines the high-performance standards of traditional EPDM with a highly reflective, environmentally friendly surface designed to cut energy costs. When used appropriately, usually in warm climates, white EPDM can reduce air-conditioning costs without sacrificing durability of the roofing system.
Is there a difference from Black EPDM rubber roofing and White EPDM rubber roofing?
In addition to the oils and the polymers used to make an EPDM membrane, another ingredient is added to the mix to enhance UV resistance. In the case of a black membrane, carbon black is added, which converts UV rays into heat. With white membrane, in lieu of carbon black, titanium dioxide is typically used to reflect UV rays and prevent it from attacking the polymer.
How long has EPDM rubber roofing been in commercial use?
For over 40 years, and with over 1 billion square feet of membrane installed worldwide, EPDM has established itself as the membrane for all climatic conditions. This is supported by various laboratory studies and actual field installations. This excellent track record is the result of unique and unmatched physical characteristics:
EPDM has superior resistance to UV (ultraviolet) radiation
- EPDM has unmatched resistance to thermal shock
- EPDM exhibits superior resistance to cyclic fatigue
- EPDM has superior resistance to hail damage
- EPDM will not become brittle and will not shatter due to low temperature flexibility
How long is my new EPDM rubber roof expected to last?
Over forty years ago the very first rubber roof was installed. With only basic maintenance, it is still in place today. Your new EPDM rubber roofing system has a life expectancy of over forty years! That is exceptional and combined with all of the great features that EDPM rubber roofing systems have to offer, your choice to have an EPDM Rubber Roofing Systems installed is a cost effective, stress free way to protect your property.
What is a TPO Roofing System?
TPO (Thermoplastic polyolefin) is a single-ply roofing membrane which is among one of the fastest growing commercial roofing products which have gained broad industry acceptance for their many performance and installation benefits. TPO fully adhered roofing systems are ideal for both low- and steep-sloped roof designs. The aesthetically pleasing white membrane is ideal in climates where reduction in cooling and heating costs are desired.
What is Fully Adhered Rubber Roofing Installation?
The EPDM fully adhered system is a lightweight roofing system with exceptional design flexibility. The ideal roofing system option for flat roofs, contoured roofs, irregularly shaped roofs and roofs that have limited load bearing capabilities.
Using panels measuring up to 30 feet by 100 feet, the membrane is bonded to the insulation, which has been physically attached, utilizing mechanical fasteners, stress plates and/or adhesives. Either non-reinforced or scrim reinforced membrane can be used, with the non-reinforced membrane making up most adhered installations. Fully adhered systems are lightweight and ideal for a wide range of building sizes and geometric configurations, including high-slope applications.
What are the benefits of the Fully Adhered Rubber Roofing Installation?
- Applicable for installation on any type of roofing slope
- Idea for unusual roofing configurations
- Lightweight rubber roofing system
- Exceptional high wind uplift performance
- Great fit for roofs with PV installation and for green roofs
