finding the leak

[waynefi]

My old TT had water damage to the floor. I never saw the water, and I was never really sure where the leak was.

I know I’m supposed to check the roof seams for leaks, but what am I looking for. Will it be obvious that there is a gap? Is the roof the most common problem?

The damage was in two places, the bathroom and near the door, which is also near the sink. Could the leak be around the door frame, or something to do with the drain pipes?

Do you remove the old caulking first? Sounds like that could cause as many problems as it fixes.

I am dealing with rubber roofs. The old trailer that had the leaks was a 2012, but now I’m more concerned about the brand new one.

Tape a box fan in place over an open window (blowing into the window). Use cardboard and tape to seal around it.

Close the door and any other windows. Set the fan to high and go around the seams with soapy water.

PS: Yes, you can often see where the sealant is pulling away but not always.

What year is your trailer? Does it have aluminum roof or rubber roof? Different problems depending on material.
