Fully-adhered roof system adhered and seamed with a common adhesive

A roofing membrane composite comprising:

• (i) a roofing membrane panel having opposed first and second planar surfaces and first and second lateral edges, said first planar surface including a roof-substrate contacting portion and a lap portion adjacent to one of said first and second lateral edges;
• (ii) a layer of UV-cured pressure-sensitive adhesive disposed on said roof-substrate contacting portion and said lap portion, where the layer of UV-cured pressure-sensitive adhesive is disposed on the entirety of the roof-substrate contacting portion from the first lateral edge to the second lateral edge, the UV-cured pressure-sensitive adhesive including a UV-cured polyacrylate having a gel content, as determined by THF extraction after boiling in THF after four hours, of at least 50% by weight, and where the polyacrylate, prior to UV curing, has a Tg of less than −20° C. and a number average molecular weight of from about 100 to about 350 kg/mol, and where the degree of cure of said UV-cured pressure-sensitive adhesive varies by no more than 10% between said roof-substrate contacting portion and said lap portion;
• and
• (iii) a release member removable affixed to said UV-cured adhesive in both said roof-substrate contacting portion and said lap portion, where said UV-cured adhesive disposed on said roof-substrate portion and said lap portion is substantially homogeneous.
