It looks MOSTLY safe. The roof should be fine.

You hesitate but lay back against the steel roof, looking up at the night sky. Carmen smiles and lays back next to you, her fingers brushing against your own. You try to ignore it and clasp your hands over your chest, gun by your side.

Carmen is saying something, speaking about the stars above, but your tiredness washes over you as you lay down. Her words drown out and your eyes flutter closed, and finally you get some semi-decent sleep.
