Cleaning an epdm roof
Good morning everyone. I am having trouble getting my epdm roof clean. I bought this 2011 Puma back in July and I don't think the previous owner ever cleaned the roof. I am presently using Lucas #1...

John,
As I said if one is to do any routine maintenance on an EDPM roof then your 4x a year especially using the 303 is IMO probably the one that I will concede is probably the best you can do and will actually extend the life of an EDPM roof. IIRC an application of 303 lasts on the order of 1 to 3 months so at 4x a year you are IMO getting 95% of the benefit of using that and even simply slapping in over even a dirty EDPM roof might be just as effective as cleaning it first and then applying 303, but we won't really know and in the end it's not that important since what you do I readily admit works and I can see why. However, you IMO are the exception to the rule on maintaining an RV in general and your roof maintenance just further demonstrates that and 99% of the folks out there would not do what you have done, nor keep their RV long enough to actually see any end benefit. Of course we can't really tell, but even the roof with all those spider cracks while looking bad are still IMO full serviceable and might last another 10 to 15 years before the membrane would actually need to be replaced and getting 15 to 25 years service out of an EDPM roof should satisify any normal persons expectations and/or requirements. I haven't actually done it, but it would not surprise me if you use upwards of 1 1/2 gal of 303 a year doing an application 4 times per year and at $50/gal over 10 years thats close to $750 in 303 alone which is almost the cost of a new membrane less installation where all the roof replacement cost is admittedly.
