Roof air removal and sealing

well, here I am again, allthough happy to have somewhere to go, so to speak, (as the list grows) just discovered after a lite rain, a drip coming threw rear ac unit. just wondering if anyone has pulled off those before, seams like 4 nuts with retention springs on all thread, wire connector for unit control, main power feed. Thought I would try caulking, However it appears that the fiberglass roof around the unit has separated also have to try to repair, ( have separation isues around lower end of unit rear area also) I was wondering about floor adheaseve pl 400 or somthing, may need something that might flow better?? as always, suggestions would be great. Thanks Ray.. someday I may get to drive somewhere?? Thanks again..

If the gasket is not too compressed (normally 1.5" thick) you should be able to tighten it down some more and get a good seal. Do not go much more than about 65" lbs of torque. If this does not resolve the leak a new gasket is in order. You are correct in removing the electric and four bolts to lift the top unit off roof. Good luck and keep us posted.

Remember though: Just because the water comes through by the a/c does not mean it is the a/c itself that is leaking. A water leak anywhere in the rear area will likely drip through the a/c opening - it's the nearest large hole in the ceiling and water runs to it like iron to a magnet.

I had a flood from the front a/c opening and the leak turned out to be several feet away.

Just an update and thanks Mike and Gary the bolts were loose and the gasket so so I had some old style plumbing cord and was able to support the unit above the roof and slip the cord all the way around under the gasket, so far so good, until I get a new gasket. so on to something else, Thanks again. Ray..
