Ceiling bump, seam, or ??
** This is my third attempt to post. After 32 years in IT perhaps I am losing my touch. Hopefully this isn't a triplicate.
Hello,
So we were on our last camp out of the season and I was laying on the bed and one of the ceiling lights were on. I looked up and noticed a small bump in center of the ceiling, looked to be about 1/2 inch by 6 inch extending cross wise (side wall to side wall). It's not soft at all and I can tell by pushing up that its not at a joist. Now, its only noticeable with a light shining across it at the right angle. While I never saw it before, it may have been there since I bought the trailer and just noticed it.
Thinking I had a possible leak I got home and washed the roof and did a caulk inspection as planned before winter layup anyways. All looks good to me.
Being that it is about a foot away from the skylight I went ahead a took down the inner skylight. I was able to put my hand in and felt right up to the area. The insulation was not wet at all, nothing was. I did feel what is like a seam going across this exact area. Feels like some hardened glue or something extends across in a line at this area as far as I can reach in and around.
Not sure how they build these, but would they put a seam in where there would be no joist? Some flexing going on at this spot with heat and cold cycles perhaps causing a slight buckle at that spot? My inner skylight cracked at one of the holes for screw near there which I noticed this spring - I think it may be related ?
I am taking a watch and wait approach to this. I was just happy that it wasn't water getting in there.
Tried a photo but it is impossible to see in a picture. Just need to be at right lighting and angle to see it. I think I will just take that bulb out of that particular light LOL.
Regards, Jim
