Roof leaking, but how and where?

Stuka · 09-11-2015, 05:19 AM

Man, there's got to be a way to find this leak and stop it. After a heavy rain, I get seepage around the top of the tub where it meets the back wall. Apparently it is leaking and running down the inside of the wall, and oozing through the seam between the wall and the tub. A few months ago I got on a ladder and applied calking to the roof seams, around the vent, and really could not see any leaks. What should I do next?

Finding the source of a roof leak can be a daunting task sometimes. First suspect is the seal around roof and tank vents. Next suspect is the edge seams. Depending on how the RV is sitting (level) water may enter and run for a bit before coming through a ceiling joint.

I hope when you said you caulked the roof, you meant you sealed with a sealant like Dicor or sikaflex. I would start taking any covers off that you can like vent covers and if the fridge vent is in the area, that too.

Inspect the entire roof front to back and pay special attention to the corners and the front cap seam. ANY gaps in sealant can and will allow water. Check the A/C to be sure its pulled tight, it has a foam seal that is compressed with 4 long bolts and over time they can loosen or the seal can deteriorate. Good luck, take your time and you'll find it.

Do you have a skylight over the tub? If so remove the trim piece inside and check for leaks around the skylight. Check the seal around the skylight on the roof.

I would agree with this. Check the sealant on the roof and look for cracks in the skylight plastic. Pull down the inner cover and look for water.
