Rubber Roof Bubbling

by Noreen
(Midway, Arkansas)

Question: I failed to maintain the roof on my 96 Coachmen Catalina and discovered water damage. The interior wall next to the sink bowed out and I now feel a soft spot in the floor nearby. I cannot see any water spots inside the bowed out wall and have tried to look through every access possible to get a glimpse of the floor (inside the cabinets, etc) but no luck... I cleaned and removed as much sealant as possible. I used Roofers Choice butyl magic tape (supposed to be like Eternabond) around the vents, antenna and along the seams and edges of the roof. I could not see any evidence of leaks from this application. I did not use it around the AC. The roof had bubbled up in spots along the rear seam by the luggage rails and the area over the bathroom vent which also had a tear. I did notice the water damage in the ceiling of the bathroom under this spot which may be the cause of the soft spot in the floor. I taped over these bubbles. I now need to use a sealer to cover the tape and the railing attachments. Would you recommend that I use a self leveling sealer (as you mentioned) or would I need to cover the entire roof with something like liquid rubber roof? Should I remain concerned about the bubbles? Also, how can I check for leaks around the windows and lights near the roof without having to remove them? Should I just seal around them anyway? What product would you recommend for that application?
