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.
  
  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.
