After our trip to the sierras we noticed that the roof on our
lite house sags in the middle causing water to puddle on the roof when level. There is a piece that runs the length of the trailer on top that was supposed to keep the roof strait but now is curved in. How would i go about strengthening it to re curve the roof in the correct direction? What would be good to add to the inside of the beam to add rigidity? i was thinking maybe a
fiberglass board and then add matting and resin around it? Thanks for the help, curt
