U225 Roof Repair

I had a couple of blisters on my roof that I was monitoring closely, then after an extended rainy spell found a leak in my driver's side bedroom storage.  Upon examination I found that the roof had cracked leading away from the skylight.
I had already dealt with the skylight.
So after accumulating some book learning and a small pallet full of fiberglass supplies I pulled the skylight and the inner trim.  I found that sealing the outside from coming in helped, but the real problem was the original skylight installation and full time living.
The skylight measures 22.5" square and the opening is 21".  In addition, the skylight was pushed up against the tank vent where it came through the roof and all of this mismatch was pushed to one side.  The resin trim piece hid this, and water was able to sit on the remaining 1.5" ledge soaking into the plywood.  By the time I gave up cutting, the opening was 4' square.
So right now I have 1/4" plywood made with waterproof glue, sealed on the inside face, and 3 layers of fiberglass and resin.  The next stretch of good weather I'll sand and gel coat the exposed surface.
And re-install the skylight modified to clear the roof vent.
And deal with the remaining .75" ledge.

I have finished the fiberglass work and applied two coats of white gel coat and one of polyvinyl alcohol so seal out the air.
What have I learned?  My 10:00 AM until Noon work schedule is sacred and not to be exceeded.  The good news is that I've met my out of pocket for the year.
I've met my roof and we are now friends.
Next time I'll build repair panels on a comfortable height bench and cut them into the roof.
I've developed enough fiberglass skill to begin repair on my bay doors.
Next week?  Clean up the skylight and cut the hole in the roof.
And as always, battle plans work until first contact with the enemy.

Owning a Foretravel  will develop skills you didn't think you needed. Looks great.

Owning a Foretravel makes it possible to develop skill you didn't think you needed.  The construction of the Rockwood was so abysmal that, well, I would have needed to do a frame up restoration.

When I have another water incursion I have a different plan of attack that will involve pre-made repair panels.
