>I would not let anything touch a rubber roof during storage or any >other time.
I'm curious about that because I've gotten a wide range of advice. Some people have told me that as long as I allow for vent air movement and "breathing", they recommended using aluminum "tubing frame" or even things like plastic gallon jugs tied together to space a tarp over a rubber roof. If a rubber roof is strong enough to walk on it and moisture is not being trapped, what is the main danger/risk you are warning against? (Obviously, if outdoors, one must always allow for rain to drain without pooling. I've seen that done quite effectively with draped tarps over plastic milk jugs tied together in heaped-clusters. What is the down side?)
(Thank you all for your helpful posts.)
