Well without a doubt you have to fix the crack around the skylight no matter what you do to the rest of the roof.
As far as the missing wood I would definitely cut through the rubber roof with a razor blade knife and see what is happening. My guess is you have had a water leak for a while and the wood rotted out.
A few thoughts on cutting the hole.
- Use a razor knife and a straight edge to make the cut.
- Cut a three sided hole (across the back and up the sides) leave the material uncut at the front (the side toward the tongue)
- Make your cut over existing good wood so you have something solid to press down against. In other words if the hole is 4' x 4' make a cut that is 4'6" x 4'6".
- Use 4" wide Eternabond tape and seal the cuts making sure to press down really hard./
If there is water damage you need to make sure you identify and fix the leak. If you can't fix the rafters then lay a sheet of plywood over the hole that is larger than the hole. Taper the edges with a sander and definitely round off any corners. If the wood on top of the hole makes the rubber roof too short you're going to have to fill the gap with something. I would probably tape a strip of Eternabond onto the wood patch under the exposed cut. Then lay the rubber back down and tape Eternabond from the rubber roof to the strips added in the middle.
just noticed what the problem was. Sorry it’s a 4“ x 4“ piece of wood that broke off under the rubber roof when I stepped on it not 4‘ x 4‘. Stupid me.
think I should do?

that is some really good advice.thank you. What I'm having a hard time understanding is the missing wood is/was sitting on nothing. there is a 2-3inch void between where the missing wood piece and the inner ceiling. there is nothing to secure the new piece of wood to (no rafter) at that location.

Well, if it were mine, I'd probably cut the rubber back a little. I'm make sure the inside of the roof was good and dry. I'd make sure the rest of the ceiling is dry, the walls are OK, and nothing is damaged by water intrusion. I'd then get a couple cans of Foam Stuff and pump as much as I could inside that hole, which will adhere the ceiling to the foamy Stuff also, as well as the underside of the roof. But it would seal it all.
Then I'd lay a sheet of tin a bit bigger than the hole between the roof and the rubber with some Liquid Nails between to seal it down. Then lay the rubber back over the tin sheet and then use Eternabond tap to seal the seams of the rubber, and last, logs of RV caulking on top of that. Then ... never step on that spot again. It will last forever.
Edit?
I'm assuming the hole went clear through to the inside, after re-reading your post? If the hole went all the way through the inside ceiling, do the same thing on the inside. Before pumping in the Foamy Stuff, simply find a decorative ceiling "pretty", like a medallion used for lights or ceiling fans. Anything that looks pretty. You can get a nice decorative covering and simply glue it to the ceiling over the hole inside. You may need to use a few fine screws or a staple gun to hold it in place. Liquid Nails is great for stuff like this.
Then when the glue dries, or Liquid Nails dries the covering over the hole, do the outside of the roof and "pump the stuff" full!
