There was a specific timeframe (2004-2007 I believe) that Jayco utilized a TPO roofing material (tough stuff) on some models that unfortunately had a "fleece" backing that laid over the roof wood sheathing. In some cases "if" moisture was able to get to the fleece backing material it would 'wick' the moisture over the wood roofing materials and could cause damage over a larger area. I had this problem with my 2005 Eagle and Jayco took care of the repair.
To the best of my knowledge Jayco hasn't used any TPO or EPDM roofing materials with a fleece backing since 2007.
IMO if the 2011 Jayco (or any other brand) your are looking at passes a complete inspection (roof, joints, ceiling, exterior/interior walls, etc.) you should be fine. Like any brand RV..., the roof, seams, and associated mounted products require a careful visual inspection at least twice a year.
