Each roofing system has unique properties. With five Roofing Systems available; 4 EPDM Membranes and 1 Liquid Rubber, we are bound to have the perfect choice for your roof. Please checkout this overview of each to decide which is best for your project.
Does it have to be dry for EPDM roofing to be laid?
Yes, EPDM Membranes require the substrate to be dry prior to installation. This is so the the adhesive & primers can effectively bond the rubber to roof deck. EPDM products will not adhere to wet or damp surfaces. Trapped moisture may vaporize and negatively affect the performance of the membranes.
Each EPDM membrane roofing system can be bonded to a range of different surfaces. This article covers the various do's and don'ts for each roofing system, the surfaces that can be bonded to and the adhesives required.
Today more than 90% of the natural rubber supply comes from Southeast Asia. As rubber trees require a hot, damp climate they grow only in the “Rubber Belt,” an equatorial zone that stretches around the world. General purpose synthetic rubber has its origin in two gases: butadiene, a by-product of petroleum refining, and styrene, captured either in the coking process or as a petroleum refining by-product.
What's the biggest size EPDM roofing sheet I can buy?
The biggest sheet size available in each system is as follows, all sheets can be joined where the roof size is bigger than the maximum sheet size:
ClassicBond & Shedcover 1.2mm - 15.25m x 30.5m (50ft x 100ft)
ClassicBond & Shedcover 1.5mm - 15.25m x 15.25m (50ft x 50ft)
DuoPly 2.54mm - 1.52m x 12.20m (5ft x 40ft)
RESITRIX 2.50mm - 1M x 10M (3ft 4" x 32ft 10")
You will typically need a standard 9" roller set, mini roller and brush for applying the adhesives and primers. A Seam Roller is a useful tool for tapes and joins and the RESITRIX system will require a heat gun for joins.
The first commercial rubber roof was installed in the United States in 1965 by Carlisle Syntec, it is now 50 years old and still going strong. This makes ClassicBond the only EPDM with a proven 50 year life expectancy!
Is there a right side up when installing ClassicBond EPDM Membranes?
Classicbond EPDM membranes are identical on both sides so there is no right or wrong side when installing. However you may sometimes find a small amount of writing printed on one side of the Rubber Membrane and it may be wise to keep this side down so an eyesore is not created.
