Ridge Roofing Inc.

EPDM – Ethylene Propylene Diene Monomer

Ridge Roofing Inc. has the ability to solve all of your roofing needs with our EPDM Roofing Systems. All systems offer a full line of accessory products and insulation. Because each product has its own individual requirements, choosing the right roof is only part of the total solution.

Selection of the appropriate attachment method, ensures every roof installed by Ridge Roofing Inc. will provide the protection and value it is designed to deliver. Depending on the membrane and application, our roofing systems can be warranted for up to 30-years

EPDM Thicknesses Available

EPDM Membranes available in .045, .060 and .075 reinforced EPDM are manufactured with a polyester reinforcement completely encapsulated between two plies of EPDM. Specially developed for Mechanically Attached Systems, Metal Retrofit and Fully Adhered Systems, the membrane offers superior fatigue and puncture resistance.

Non-reinforced membrane, in 60-mil thickness is available in 10′ widths and 50′ and 100′ lengths, which helps reduce seams and lower installation costs. It has UL Class A, B and Universal Slope ratings available over most deck types.

About EPDM:

EPDM is a synthetic rubber material that can be formulated with extensive flexibility for use as rubber membrane sheet roofing. EPDM is used for flat roofing as a vulcanized material. When you think of an inner tube for a tire, that is basically the same material we are talking about when it comes to EPDM rubber roofing. EPDM membranes exhibit good resistance to ozone, UV rays, weathering, and abrasion. EPDM also has good low temperature flexibility. EPDM is resistant to some acids; alkalis; and oxygenated solvents, such as ketones, esters and alcohols. On the other hand, exposure to animal and vegetable oils and petroleum based products, should be avoided to prevent membrane swelling and distortion, and possible deterioration.

Rubber roof system performance is a function of several factors, including proper splice and end lap construction, membrane sheet layout, fastener spacing and installation, and surfacing application. Material manufacturers/ suppliers may have proprietary requirements for these factors. The most effective means to evaluate the quality of a rubber roof membrane installation is by thorough, continuous visual inspection and evaluation at the time of the application by a person who is knowledgeable of rubber roof technology and good workmanship practices.

Adhesives of different types (e.g., contact adhesive, tape), primers and conditioners are used in the construction of rubber roof membrane systems. On the same project, more than one adhesive may be used. For example, in the installation of an adhered rubber membrane, one type of adhesive may be used to adhere the membrane to its substrate, another type may be used to adhere the seams, and a third may be used to adhere the flashings to masonry or to metal edge components. Different primers may be needed to work in conjunction with these adhesives.

It is important that the proper adhesive be used only for its intended purpose. Substituting one adhesive for another may affect both the long- and short-term performance of the roof system.
