Anybody ever replaced a rubber roof as a DIY project? These
folks offer a "kit" with instructional video:

Anybody know anything about this? Apparently over the years my roof has
leaked a slight amouint at a time and the plywood underlayment has
rotted out. I cut a 2" triangular slit in it and the wood is just
plumb rotted. It's only a small area near the front, probably about
6-8 sq. ft., but an RV repair shop told me they replace the entire
roof in a case like that, pretty expensive, and I suppose most of that
expense is labor.

I doubt it is labor. Most of the expense is likely the glues you need
to apply the roof. I suspect your roof didn't fail, the calking is
likely what failed.

Whatever it was that failed, the end result is the same - the wood
underlayment is rotted out. The rotten wood is not wet, so the leak
has stopped somehow.

All of the rotted wood would have to be replaced before applying any type of
roof sealer.

I would agree with Bob V.,
I have rebuilded a roof on a pop-up, not saying it is the same or different.

First look at where the leaks are, look hard as someone said water WILL find
the path of least resistance.

See where it is getting in. Probably a calk line next to a seem.

It is time to open her up like a sardine can.
Find where it is leaking first then peel/open the rubber replace ALL wood
that is rotted. I know this is a PIA (pain in the buttocks) but your work
will be complete.

If it is Only the plywood be thankful.
Check the main beams. Solid pieces that provied frame work.

The rot is probably around the window which is facing forward in about a 22
degree pitch.
Your calking failed, about 2 yrs ago based upon the ply rotting and when
traveling wind makes it worse.

A few solutions:
Remove the window and rebuild the wood with frame and plywood. This is the
best option as every window in the front of an RV leaks.
Also, I hate the heat generated in this window.
I have never opened the front yet it continues to haunt me.

When rebuilding the framework use "Treated wood for all framing."

Also,
If you want to fix a leak forever, use truckbed liner. The trade off is in
the weight and what it will be hauling.
This is where you MUST replace all damaged wood framing.
