folks I am sorry that I have ingnored this blog since july of 2010. I hope to spend more time and provide more information in 2011. I did have a question posted in 2010 about bicycle patch kits and why would'nt they work for EPDM roofing. A bicycle tire tube is mostly made of butyl rubber which is easier to stick a patch to than EPDM. The thickness of the intertube is usually under .020mil. The thickness of the EPDM roofing is usually .045 mil. So a patch kit designed for EPDM would be thicker and work better. I am not saying that bicycle patch would not work for small holes but it would not be recommended by the manufacture. Remember however you patch your rubber roof to be sure to clean it thourghly. This is the single most important thing you can do to make any patch stick.
