Howdy,
Called Alpha Systems and they said as long as I got surface dirt off and the existing material isn't hard and crumbling (which it is not) or moldy/mildew slimy (which it is not), I am good to go with laying new material down on top of the old. The old material is still adhered well to the membrane and I'm not about to try to peel it off and really make a mess of things (that would be a real battle). Just odd that it is a stained brown color on the surface (still white underneath if you scratch it), but they said don't worry about it, their stuff will adhere to it. So I will attack it today.
