Do I have a STYROFOAM ROOF ??

Is it domed like the current (32)BHDS?

[dcavaiani]

Yes, I would say so .........

[dcavaiani]

It is mushy and "crunchy" in several spots around the roof, so might that indicate Styrofoam?

[ctbailey]

mushy and crunchy is not a good sign.

The roof is currently made up with wooden trusses for structure, but then would use a luan and styrofoam for the skin and integrated insulation. Of course wrapped in rubber roof membrane.

If the luan (possibly plywood) is rotted then you could definitely feel the styro insulation.

This needs to be dealt with as soon as possible. The buggies love moving under the rubber membrane, causing a bad situation into a a terrible situation.

I would start on the inside of the coach, go through the ceiling to inspect. ceilings are cheap, Rubber roof membranes are extremely expensive.

You can cut and patch the rubber roof. when doing the actual repair.

This can be done DIY, but needs to be dealt with sooner than later. Remember, "rot" is really just wet wood that has become a breeding ground for microorganisms that feed on wood, and they can work in a low oxygen environment. In fact, they prefer places that are water impenetrable, because the membrane retards the natural drying action that exposed wood would see.

I am truly sorry you are feeling squashiness on your roof. I had a similar situation, but mine was a squishy floor on a previous trailer. I feel your pain, and wish you the best of luck.

It should be 3/8" plywood over wooden trusses, covered by the roof membrane since it is a Jayflight.

I called a local RV Medic and right away he wants to tow it in and replace the whole roof for around 5K. Did not excite me - especially when I see videos where only the bad portion of the roof can be replaced! My concern though is that there are a few other "crunchy" spots near the sloped sides in very different parts of the roof where there are no leaks at all, and where there are no low spots. wondering why that would be??

Short answer is you'll never know for sure until you put eyes on it.

Home Depot is now selling flexible fiber optic cameras that will "see" in a wall cavity from a small drilled hole...

Our 2005 31bhds was the same way, we figured it out while installing a new Ac unit. Luckily a tree limb came through it during a storm, and our insurance paid for a new roof that I installed myself. When I started tearing off the old roof I realized that one whole side of the roof was rotted, so I tore off all of the plywood which was 3/8" Luann, we replaced this with 1/2" plywood as it was readily available, and there is not that much difference in weight. I then installed 1/4" styrofoam insulation and .045 TPO rubber roofing. This was a major undertaking and I probably had over 100 hours of labor in this project with removing Ac, guttering, vents, and cleaning all of these items for reinstallation. Our insurance paid $2500.00 for a new roof which certainly would not have covered a repair facility doing the job. Good luck, and make sure that your repair guy knows what he is doing or you will have more problems than you already have. If yours is like ours was there is know sign of a leak inside, although the condition of the wood indicated that it had probably leaked since it was brand new. I have read on some forums that several years of jay flights had a fabric backed rubber membrane that wicked water and held it on the roof deck. Sorry for the long response, but I can feel your pain.

well first off, is there any delam on the sides of your unit? If so, is the roof crunchy right over the delam? That is where the water is going out, not necessarily where it is coming in.
As far as repairing just a portion of the roof. YES, you can just repair the wood, but if you pull up just a part of the rubber, it will stretch, and the glue wont stick properly when reattached. The actual rubber roof replacement kit does not cost that much. It is the labor that costs, and why risk an ify reattach. Spend a few more $$$ and replace the entire rubber.

JAYCO is very good with prompt answers to qustions like this. Call them and have your VIN NUMBER handy...

I got a full build PDF one time asking about how thick the walls were back then...
