Shower Skylite leak

Had a really heavy rain storm last week and now I have discovered that we have a leak in the shower skylite.  Am thinking that Eternabond tape would be  a good fix for this.  Around the outside frame probably?  Anyone have any thoughts.  Only thing is that Eternabond is almost permanent and next to impossible to remove.  Maybe Dicor tape would be better?

I would think that if your skylight is in good shape I'd be inclined to use the Eternabond. I used it on my last motorhome to seal the caps a the rubber roof and all around the vents, including the refer vent/s, and skylight and never had a problem with leaks or having to remove it. The biggest thing is trying to keep it smooth while applying. At the caps to roof I did not roll it over to show. Instead I stopped short and caulked the sides of the roof whee it meets the sides of the moho. Eternabond is great stuff. Apply once and forget about it. Make sure and follow their instructions. Once you use it there is no more caulking to do where it was used. I used he 4" wide tape.

Thanks Jon.  This leak really caught me by surprise.  The coach has been thru several heavy thunderstorms with heavy rain and no problems.  But this storm had a 1 mile wide EF2 tornado touch down about 7 miles away along with several other smaller ones also hitting the area.  Had the shower perfectly clean and went out yesterday to do some work and found a dirty shower.  The sky lite itself is in good shape.  We don't normally get many tornados here.

Pat, On mine the skylite consists of a square box that fits over another square box on the roof.  By removing the screws around the edge you can remove the skylite and then reseal it with builders grade silicon. This will also allow you to inspect the box attached to the roof for cracks etc. and may make it easier to seal with skylite off.

Thanks Gary,  Going to have to get up there on top and look at it again.  Been a while and with a steel plate on one femur, two bad knees, and a skinny ladder, I don't like going up there.

My problem with leaks is......where is it, really?  I also thought my skylite was leaking...after many tries and attempts found I had a crack in the roof; under the aft air conditioner, which no one found till removing shroud....

Part of the problem is that the skylight base is flat and the roof is slightly crowned and upon removal of the whole skylight you will find that some of the screws may be screwed into only the fiberglass/wood sandwich and not into any aluminum framing. With all of the vibration the screws work loose and the caulking seperates. I think Eternabond would be temporary solution if you see the base of the skylight popped up. What I found was that the coach aluminum framing was not the same size as the skylight so it accomodate the skylight frame mounting flange. I built a reducer to bring the size down and to allow a standard 14 x 14 fantastic fan to be mounted. The reducer is built to maintain the same headroom in the shower. I was able to fish a wire over to the existing fan to power the new one. I looked for a picture of the final product but it must be on my other computer

Mine only leaked one time.  It was during extremely heavy rain and high 50 mph wind.  I was not at home at the time it happened, and do not know which direction the rain came from.  But my s-i-l was able to sit on her elevated deck on the south side of her house during this storm and not get a drop of rain when it was pouring.  The deck never got wet, yet it was a downpour with the rain going sideways.  Going to pull the box off and see what is what, and then approach it logically.

I doubt it would be a crack under aft air conditioner, because the water would have to run up hill where I am parked.  But I have seen  crazier things
