It seems to me that your over thinking the roof. If you have no penetrations you won't have much reason to walk on it and even so there's no reason you can't walk on TPO or EPDM. Our trailers have a translucent fiberglass cloth on the roof and we can walk on it. These trailers do a lot of twisting and shaking in their 100K miles/year and I've never had a roof leak. I wouldn't put AL on the roof.
