1978 winnebago brave renos and roof replacement

[Leon bourassa]

Hey guys,
I'm in the process of doing a full Reno on my 1978 winnebago brave, and I've run into a bit of a predicament. Wen I removed the roof, I performed a not so graceful cut and toss procedure. The inside has now been completely gutted as I couldn't see a way of accessing the screws holding the roof down without removing all upper cabinets, which were attached to the lower cabinets and the bathroom walls, and so on and so forth...

Anyway, rv is gutted, and I have reframed the roof using 2x4s cut at a radius. Joining the new roof sheeting was easy enough, but I am having trouble figuring out a solid plan for connecting the rear. The back radius seems to be nothing but tin and foam. I have a small amount of the radius still intact, and I'm not sure if I should cut it off, or what. I've read a number of write ups on roof replacement, but none of them seem to reference how they made the transition from old to new.

The new roof is sheeted with 2layers of 3/8" exterior plywood, and will be covered with commercial grade epdm rubber.

Any help would be appreciated.

Your new roof looks good!    Dad and I did this to a 1972 Winnebago a few years ago.    The 2nd to the last truss we made half as tall with a bit less curve, then the end truss we left flat.   This allowed the original back of the RV to match up to the new roof line.      You can do the same thing to the front but leave about a foot of the old roof so you can fold it over the new rubber roof.    From the ground you couldn't even tell it was a curved roof.

We also only used one layer of 1/4" plywood.   At one time we had Black EPDM rubber on it, later we replaced it with white TPO.  (White makes a HUGE difference in the summer time)

Tim's first Winnebago motorhome roof replacement looked great.When Tim and his dad finished that RV the interior was upgraded as well.Check out Tim's photo's.

i was just curious, where did you buy the EPDM?

[Leon bourassa]

I got the rubber straight from work. We build rig camps and use the rubber for our roofs

[John D]

is this stuff available at places like Home Depot and Lowes?  will the roofing rubber work with a coat of Kool Seal?

[Leon bourassa]

I honestly have no idea. We get it from a building supplies wholesaler.

My neighbor worked for a roofing company and gave me enough EPDM to cover the roof.    Later I replaced it with white TPO, I found it on Ebay.     Its a lot tougher than EPDM, but stiffer to work with.
