RV Repair: Rubber roof repair, rubber roofs, razor knife

Question
I have a 37' 1997 Newmar Mt. Aire.  A small air bubble has formed right in the front of the rubber roof and migrated its way (as you drive the airflow over the top creates a vacum) into about a 4' by 5' loose patch of rubber on the roof.  The roof is still secured by the trim strip but the lifting action has allowed a small cut to develop as the bubble rubbed against the front of the air horn.  I have it sealed up for now but there was a bit of watter that got in underneath the roof and has softened the a 2' by 2' section of the roof structure under the rubber.

What material, tools and procedures do I need to be aware of when attempting to repair this problem?

Answer
If it were mine, I would use a razor knife and cut out the entire loose roof area about an inch or two beyond the loose area all the way around (cut only deep enough to cut the rubber roofing material).  Once cut out, I would make sure the area under it is completely dry.  I would then reglue the patch back on the roof with a good RV glue and then use a good RV caulk to reseal the seam where you cut. I would then coat the entire area (overlapping the patch) with a rubberized roof material available at most RV parts outlets.
Once you get moisture behind the protective skin, it can only lead to rotted panels and once that happens, the fun really begins.
I am not a fan of rubber roofs for exactly this reason.  I much prefer fiberglass or aluminum.
