Question I have a 20 year old rubber roof-flat. It needs patching and coating. It has been patched before with (I think) some asphalt patch and, about 5 years ago, coated with fibered aluminmum coating--apparently a mistake. What kind of patching & coating can I use?
Answer Richard,
You do not ever want to use asphalt products on EPDM (rubber). If all of the old coating is worn off, you may use an elastomeric coating formulated for EPDM or a Hypalon based coating. The Hypalon is the best for long term adhesion and performance.
Patching of the rubber should be performed with pressure sensitive tapes and primer. Make sure the roof is clean clean clean prior to any patching or coating work. If you have a 45mil thick rubber membrane, it may be prudent to replace the entire membrane as it has a limited life remaining (typical). If you have a 60mil thick membrane, and if you get a good job, the repair should last as long as the membrane has left in it; about another 10 years.
