Best way to correct a bent down roof?
My daughter's bus (which I'm working on) was used as a Burning Man vehicle for about 9 years, and that included multiple occasions of people dancing on the roof - up to 20 apparently. As a result, the rooftop is a little low in the middle, maybe 3/8 inch or so. It's not a lot, but it does mean water pools up on the top of the bus.
Right now the interior is gutted, and I've propped a few long pieces of wood between floor and ceiling ribs to push it up. If I remove them, the roof goes back down a bit. I suppose if I leave them a while (or push so hard I actually put a bend in the ribs) that might make it permanent.
Thoughs? Anyone else dealt with this?
