Rubber Roof Problem

I have a 2015 36-foot Crossroads Rushmore 5th-wheel purchased in December 2014 so it was 6 months out of warranty when the problem occurred.

While driving from Glyndon, MN to Bismarck, ND on 6/25/2016, and from Bismarck, ND to Medora, ND on 6/26/2016, we were driving west into a dead-on head wind of 25 mph with gusts to 40 or 45 mph. This was a total of about 350 miles as the strong winds were present all day, both days.
After positioning the trailer at the Medora Campgrounds campsite, I noticed a ripple in the rubber roof membrane about 2-feet to the rear of the joint at the front fiberglass cap.

Also, there was a gap in the caulking almost the entire length of the joint between the fiberglass cap and the roof membrane. The membrane had moved toward the rear about 3/4-inch and taken half of the caulking with it, leaving a gap in the caulking. Note: The edge of the membrane never came out from under the fiberglass cap.

I was able to work the ripple forward and back under the fiberglass cap, and mostly closed-up the gap in the caulking, but it needed sealant applied as the joint was no longer water-tight. I found a local RV tech who installed a patch over the gap which we hoped would get us home where a more complete repair could be done.

After we arrived home, I noted that the ripples had once again appeared plus there was an indication that the membrane had started to pull out from the left and right side rain gutters as well. The rubber membrane was no longer glued to the plywood for at least the first 12 feet back from the fiberglass cap, maybe even further back.

My question is what options should be possible for fixing the roof? My expectation was that the rubber membrane could be re-glued to the plywood since it is still intact with no cuts or tears; however, my dealer tells me that the only fix that will prevent future problems is to completely replace the roof (rubber membrane) to the tune of $9000. The service manager says that the existing membrane has been stretched by the wind, and it will never lay down correctly again.

Has anyone gone thru a similar problem, and if so, how was it repaired?

We has a problem with our roof last year where the staples wer coming through. Luckily it was covered by warranty. We had a new roof put on at the factory. This was in July. We stopped at Erie, PA on the way home, then went on to Niagara Falls. This is where I noticed ripples in our roof. This was a brand new roof! So we took pictures of it and found a local RV tech who fixed the problem. He had to glue the front part down again and he added a second strap to keep it down. We have taken a number of trips since then (PEI, Florida, Alaska) and so far it has held.

I can email you the invoice from him if you want to read what he did. We sent the invoice along with pictures before and after to Crossroads and they reimbursed us.

There are company's now that apply a coating on the roof with lifetime guarantee that is better than the rubber membrane. A lot less than 9000.00

I think that is called RV Armor. I haven't seen any reviews. Curious about it.

I read the article about RV Armor that was in a recent issue of Trailer Life magazine. The coating is applied over a rubber roof, and the rubber must still be glued to the underlayment. In fact, the article says that if the rubber has come loose, the company can also re-glue it.

I would like to see some pics of the repair to your roof if it's not too much trouble...Have seen many RV's (mostly 5ers) running down the road with a big roof bubble right behind the front cap...You know the membrane was not glued down properly...

Yep.....friends here have new Montana Legacy. Went to Michigan, and on return trip roof peeled back. No glue under it at all.

Sorry, I checked and it looks like I deleted the pictures.

I have a 2016 Crossroads Cruiser CF351MK and I am sure without looking up paperwork that the rubber roof is warranted for 10 years. I would think your repairs should be covered by factory warranty. Have you contacted Customer Service by phone?
