Class A Rubber Roof is Sticky

[Class A Rubber Roof is Sticky]

Bought this 2003 Georgetown by fr early 2015 and thought I had checked it out really well. went up on the roof and inspected everything and all looked fine. the roof looked to have a fresh coat of rubber roof paint or roll on sealant applied. had a medical problem after I returned home and haven`t been out since last year. when I went up on the roof to check things I found dry leaves had stuck to the roof and the surface was sticky but not so much that I couldn't walk on it. does anyone know what`s making the roof sticky? when I was up there last year the roof surface was dry and cured. am at a loss
