I think i could stand on my foamie roof but i wont try it, dont want to dent it or risk cracking it. Its 1.5 thick 5x12 and i think it could handle it, their pretty strong.
But for snow load here its 22 pounds per square foot minimum. Everything ive built in construction was built for more than that, i think every engineer does here anyway, and roofs still collapse on newer buildings every few years when we get a big snowfall. 2 years ago there were over 20 barn roofs collapsed just in the county i grew up in. But anyway, if you stand on the roof its more like 150 pounds (or whatever you weigh) in the square foot you stand on, but 22 psf means the whole roof, which for my trailer means 1320 pounds total spread out over the whole roof. So im putting vertical supports up to the spars for the winter, lol.
Still pretty light weight, tho.
