The black areas are not wear. It is black mold that grows on the surface of the membrane caused by dirt and moisture. That's why you should clean and treat the membrane 4 times a year as recommended by Dicor to help prevent the black mold. I have used bleach full strength to get rid of the black mold on my roof. Attached are instructions from Dicor that came with my RV for maintaining the membrane including using bleach full strength on it.

I just bought eternabond tape from amazon. $50 for a 50 ft roll. This stuff sounds amazing.

The whole rubber roof coating idea scares me!

Just a thought!

I used Liquid EPDM Rubber on my 36 ft 5th wheel over 5 years ago. It still looks like the day I did it, no more white chalking down the sides and it doesn't grow black mold like the bare membrane did.

Thank you very much. I am glad to read that it has lasted now 5 years. We will use scaffolding for the edges, this is a very good idea.

Do I need to put plastic all around the motorhome with tapes to protects the outside walls from the Primer-cleaner? I saw a video where the professionnal was doing this. Another guy said he did wash the walls and then spray wax in the hope to protect the walls from the primer-cleaner.

It scare me too and this is why I created this thread. But I am loosing my roof so I think I have no other cheap choice. It will cost me 900$Can total. 600 for the EDPM and primer. 200$ for a man found on internet for a day of work and 135$ of various cleaning products to clean the whole exterior, rubbers.

I got all my supplies from Alpha this year for under 400 shipped. My roof looked like yours. The primer from Alpha will be tackey when the coating is applied. My RV will stay the same temp inside as out side. It did all day yesterday and it was 90 out. The new coating has to be working better then a half black roof. I posted before and after pics in another post. Tip do the curve to the sides first, then the flatroof.

1 - In fact 400$US is like 600$Canadian including sales taxes of 15.56% in Quebec.

2 - I bought the products from Dicor. The primer is also a cleaner. Is it good enough for my Alpha roof? We put it and then we get rid of it with water.

BTW, do I need to put plastic all around the motorhome with tapes to protect the outside walls from the Primer-cleaner?

I did cover the sides with a thin plastic drop cloth

Thank you. This is reassuring to read this. I have someone do my roof tomorrow if there is no rain for 200$ Can. I will put a Camco Cyclone sewer vent by the same occasion.

Thank you for the comments and advice to everybody.

Just did my roof. I have a 36' motorhome but only 30' is EDPM. So base on what Dicor say I needed 4 gallons. We used 2.5 gallons on three layers. Dicor say to put a minimum of 2 layers so it means 2 is a minimum. The roof is now white but we can still see where it was black before. So I could put 2 more layers or 3 and then spend 4 gallons. So 4 gallons is possible but people quit after 2 or 3 layers.

The result is very good. We were able to do it in a single day. We put plastic paper all around the motorhome just in case, it was 2 hours job to put this on and was not very necessary in my opinion.

I have a Fleetwood Pace Arrow Vision 1999. Fleetwood have EDPM Alpha type roof so it is very important to put the primer-cleaner first.

My roof looks like new now.
