Roof Replace

I am having to replace the roof on a Jayco Siesmic 310W 2015 Toy hauler. It seems that the bolts that hold in the three mounted AC units have been leaking...allowing for water to seep into the roof and wood substrate. There are now 2 specific soft spots when walking on the roof and you can see the sag in the roof in those areas. Absolutely no tears or penetrations in the roof membrane itself. VERY bummed. Again it lines up with 20 other issues I have repaired on my own and points to how quick and sloppy they build these units with very little attention to detail. I will replace the entire roof and water damaged wood substrate with a Rv FlexArmor.... (RVroof.com) solving forever any issues with leaks. This is a spay on 167mm thick coating compared to the 27 rubber membrane EPDM. Anyone else experience a roof issue like this?

Sorry your going through this. The AC bolts are notorious for vibrating loose, I check our just about every trip. Good luck..

You may solve leaks forever in other areas but if you let the bolts get loose again the water will once again flow into the roof rotting it out. Nothing is perfect and maintenance free, need to check the bolts now and then

Understood....NOW. Dealer never mentioned it in the PDI. Cleaning roof....and resealing caulking around vents etc...yes that was mentioned, and that work has been performed. But how a 4 bolt system can come loose and allow for water to seep through a gasket is not acceptable. I am an engineer by trade. We have to design things better than this. From what I have been told if you over tighten them, they will leak as well after over compressing the gasket.

I check my bolts every year or two. They where only loose when I purchased the camper.

Yes, you do not want to over tighten them. Over time, you may need to tighten them. When the gasket is fully collapsed, then you need to replace it.

This may be a dumb question, but how do you get access to see the bolts. I guess you have to remove the air conditioner plastic cover???

Very disturbing, I am sorry. I agree with you. this is just another case of "designed, assembled and/or installed to fail." We are about a decade off from our next RV purchase. At that point, We may downsize to something like an Oliver, not because we want to go smaller, but to get something with fewer problems and maintenance issues as we get older. There has to be a better way.

What I have done is lift the roof material careful and installed 2 x 1/2" ply strips under the roof material. Never had this problem again from leaking. It doesn't mean I have to check the bolts every season. RV's have lots of design flaws its is just a matter to fix them as a owner. You get what you buy, if you don't like it, don't buy.

Take the grill on the inside off and in each corner is a small bolt that pulls the unit down. Just tighten them enough to snug them. As stated before , do not wrench it down.

Thanks for the response, but on my 2016 Jayco 355W, there is no access to the middle air conditioner unit. The finished interior ceiling hides and covers the actual air conditioner mount in the roof assembly as shown in picture. However the main bedroom unit does have access. Scary with the middle one, you won't know until a problem arises, then it's too late.
