Again, the rubber roof itself will very, very rarely spring a leak - even at 20 - 25 years and more, from what they told me. The problem areas are the seals around everything - and that should be checked at least every year. Let me put it this way - rubber roofs, the same kind as on rv's - are on many, many businesses - including a large amount of Wal-mart stores. Why? Because they don't require maintenance.
That said - my rubber roof got damaged along an edge. I fixed it with the same stuff you'd use to seal around the air conditioner, etc. And I learned the hard way not to use the wrong product - as the first one I purchased and someone else put on for me, didn't work correctly - I'll bet you it had petroleum in it. But the 2nd one I purchased and did myself, did not - although I don't know for sure it was called Lap Sealant - going to have to check
