Hello Garry,
I just purchased a 1987 coachmen catalina motorhome with of all things a bad roof. The motorhome sat for a couple of years while an elderly gent owned it and it leaked due to standing water. The roof is in pretty bad shape in the center but not so bad out to ward the sides. My question to you is not so much from a greenhorn perspective as it is in looking for good suggestions to give this puppy some pitch, I have repaired leak damage before on a slide in and Im confident in what I have bought and my/our skill set to get this done right. Im pretty sure it is a metal frame sanwiched by the interior ply and an exterior ply with metal on top. About 1/2 of the roof is junk and the plan is to open this thing like a sardine can - come up with a pitch and put it back together.
The side molding on this coach seems to promote standing water as there is no easy escape for it with the molding creating about a 1/4'' lip it would need to jump. What can I use and where can I get a product or new molding that will lose that lip? Any suggestions you have are greatly appreciated by both me and my two devoted helpers in what some have said "your nuts" for trying. The coach has only 18K on it and is otherwise Mint - and I generally do not use that term mildly.
Best Regards and Thank you.
Justin

Justin,

    First off, WOW, I will have to agree, you have a big project on your hands. You have the right approach, open it like a sardine can and see what is left, what is salvagable.  Just about any RV supplier should have a catalog with several different types of mouldings to choose from. You can see our catalog online at WWW.NICHOLSRV.COM

Answer
If you want to put pitch in the roof, cut strips of luan plywood and lay them accross the roof trusses and secure them.  gradually cut them shorter, securing each one,(staples work best) and over lay the previous until you have the rise in the middle you want.  It doesn't take much.  The standard for plumbing is 1" drop for 8 feet of run but you wouldn't need that much just to have enough run off in this application.
