RV Repair: Roof Replacement, vent holes, metal roofs

Question
I was just given a 197? Shasta 20ft travel trailer but it had a leak for a long time and I have 1/4 of the floor removed to to total rot. I want to replace the roof with a coplete new piece of sheet metal since their repair did not work. how do I do this.
                         Thanks.

Answer
Metal roofs are pretty much a thing of the past. I recommend putting on a rubber roof.
Here are instructions -
I would plan on about a weeks time for 2 people who have never attempted this. You will have to remove everything that is attached to the roof first. Then remove the old metal roof. Next you will need to sand the decking to get it ready for the new roof, and put masking tape over the seams where the decking joins. Then you can put the glue down with a brush or roller (roller with a long handle is easiest) and roll the rubber out. It's a good idea to roll the rubber out completely first to make sure that it is square on the roof and then roll it about half way up and start gluing down and then glue the other half. Be careful not to step in the vent holes, etc., while they are covered up. Then all that's left is to remount everything that was previously removed.
