Cut in roof membrane and a void below.
I just discovered a cut, 1/2" to 3/4 " long, in my rubber roof and there is a void a little bigger than a large egg, rotted or soft wood I imagine, below the cut. Probably been there for a while. It is near the edge and at the intersection of a longitudinal beam and a cross beam. What is the best way to repair it?? Do I open the hole up large enough to replace the wood? Do I just seal the hole and live with the void? Undo the edge and lift the roof membrane, if that is possible, to get at the problem.
Please let me know what your thoughts and experience is in this situation.
