Tissue paper for roofing?

[TrainNut]

I heard about this idea some time ago and thought I'd try it on a couple structures I got from Mooreway. The results, hmmm welll, I think it needs more work. I tore little strips off of single ply TP, laid them down in rows on the roof, dripped watered down Elmers on top of that. When the watered down Elmers came into contact with the TP, it expanded, leaving ridges. I tried pulling on the edges ever so gently to stretch it back out and smooth out the ridges but it was so fragile after becoming wet that most of the time, it just tore. After it had all dried, for some reason, I went over it with a brown marker instead of black... I guess I wanted a different roof texture. The results are... hmmm, well less than ideal.
