It is pliable and puddled in several places HELP !!
As I said in the other topic, your material is rubber. It is actually a rubber material with a cardboard like material called bud board underneath. If you have a true roof leak, the ceiling luan panel should be rippled from the water getting it wet. Unless you see true tears in your roof, there should be no need to patch/replace it. Most likely, you need to just seal your seams at all edges and at roof accessories like roof vents and vent caps. If this was never done by previous owner(s), it should be done ASAP. The product I've used for sealing seams is Dyco Seam Seal. It simply brushes on the seams like thick paint:
It should be available at your local RV store.
I wouldn't worry about any minor puddling on the roof unless there is a tear in the area where it has puddled or it is near a seam. My roof is sagged right now between the rafters because it had been snowed on and once I cleaned it off, it hasn't gotten warm enough for the rubber to take back its normal shape. If it were raining at the moment (which it did earlier this evening), it would be puddled between the rafters.
If you don't have time to get to it soon, I would suggest covering it with a RV cover, or at last resort, an ordinary tarp. Tarps aren't good because they can trap moisture underneath on the roof, but in your case, it would prevent more moisture from getting in than it would trap.
