The 12:54 to Asgard

I've started this one several times, but I keep getting stuck on puzzle 1 - fixing a roof. I don't know how to fix a roof out of game, but my character should know in-game, and he wasn't helping me at all. The problem for me was having too many pieces of potential solutions, lots of equipment that could maybe be used to patch a roof, but I could not figure out how/if to combine them. I consider that not having played it, and I am not going to really review it based on that alone.
