EPDM Roofing

I am currently restoring a 1982 model camper-trailer. The steel roof is perforated with tiny holes. Can I install EPDM rubber roofing directly over the steel?  If not, can I put down 1/2 or 1/4 in. plywood onto the roof, then install the EPDM onto that? The ceiling joiists are in good condition. The trailer is 8ft.by 28 ft. I plan to remove all projections from the roof before applying the roof.

I wouldn't recommend using the EPDM rubber roofing because of what is involved. I would use the EPDM coating, it goes on much like paint. Do an internet search for " how to apply EPDM coat video", it will explain the prep work and how to apply it.

Thanks for your reply. When you say "because of what is involved", what do you mean? The metal roof I now have is now perforated with literally thousands of tiny holes, and I don't know if a roll coating will suffice.

Can you upload a picture of the roof ?

ron45,

   I did the google search as you suggested for the liquid rubber roofing, and I think you are right.  It looks like that product will fill the bill just right. The videos were very encouraging, and it looks like the project is very do-able and relatively inexpensive.  I am not quite ready, yet, but I will keep you posted as to how it goes. Thanks
