A few low spots

[Lindey S]

I have a few slight low spots on the roof where water gathers on my 2005 Jayco Jayfeather camper, what is the best way to fix this, It does not appear to leak at this point in time but just wondering if there is a way to do a fix?

Are you talking about on your roof? How deep are these low spots and where are they? You may already have taken on water. The AC units are notorious for having the mounting screws loosen over time allowing water to seep under the seal and into the roof. Most of us tighten them down once a year.

In the 2000s unfortunately the roofs were still flat. The newer models have a slight crown in them.

We just purchased it last Wednesday.

A few spots right close to the edge, and yes a bit right close to the AC. Underneath the AC the ceiling has a very slight wave but it did just rain very hard a few days before we purchased it and also since we purchased it, and we can see any water on the inside.

Maybe there is a very slight leak? When I touch the wavy ceiling it doesn't feel like their is any water there right now.

Problem may be, if water gets in, it runs down the wall and if this is done over a period of time, it can rot the wall. NO amount of water is "OK". I doubt you would feel water in the ceiling, perhaps just a soft spot if rot has started.



Good Luck...

X2 what Wags said.

That cover looks like it has water stains on it, like enough water seeped through there to cause drips at one point. I'd take that cover off and inspect inside and see what it looks like.

Those screw heads look rusty. A good way to know is to pull one of those screws out of the corner. If the threads are rusty then you’ve had water or are still getting water in there somewhere.

Ok, I will check that tonight, any tips on what to do if there has been slight leakage? Is a total roof replacement the only true solution?

[Screwby]

No, if it’s been a small leak and you don’t have major damage or mold then you just need to find the leak and seal it. Rule of thumb is check the roof seams for leaks every year. I do it every six months at least. Water can travel long distances and sometimes even uphill a little. So go on the roof and inspect every single seam, antenna mount, AC flange under the plastic cover, skylight, fridge vent....if it goes through the roof inspect it’s condition. Dicor (the gooey white stuff you’ll see up there) has a tendency to age and crack. If it looks like it might be, go over it with some new Dicor or Eternabond tape. Seal that thing up, every screw, every seam, if water can get in seal it up or pay the price down the road!
