I've got a 2004 CM Norstar - has the fiberglass roof that is (somewhat) like the Harts...it was built about 6 months out of the window from the big recall that CM had years ago about the roofs being bad.  Even if it fell in that window it wouldn't help me any as I'm probably the 2nd or 3rd owner. 

I've had it for about 3-4 months and when I got it the roof was leaking...something that WAS disclosed.  I went on top and removed all the outer caulk and recaulked the entire outer seals/bolts, as well as the mid seams...and it no longer leaks.

My question is...it appears that the original owner had a trailer place put an extra coating of "something" on the rest of the roof.   CM and other dealers said that they put an epoxy on the roofs of these years models to assist in keeping the roof from leaking. 

Only thing is that...now the "epoxy" is no longer adhering to the roof and has a bubble effect all across the roof - which of course allows for water to pool when it is parked and not under any cover.  The water does not seep through. 

Any ideas on how to remedy this?  CM just flat out said to replace the roof at a cost of $5k.  It looks like the epoxy could be removed and reapplied.  Like I said...its not leaking now...just trying to be proactive...

thanks

The only way to properly remove the loose epoxy is by sanding. Do not use heat or chemical strippers. A random orbit sander with 80 grit paper, will leave a finished surface that can be over coated with a variety of products.

A new gell coating can be applied. The roof can be painted with a variety of products. Elastomeric products can be used. All of these remedies can be addressed for a fraction of your $5000 quote, that will result in a newly finished, long lasting roof.

All of these applications can be addressed in a DIY fashion, with the only initial cost being a sander, respirator, sand paper, masking materials, and some prepsol or acetone.

Thanks for the responses...removal of it would be pretty easy as it appears to still only really be attached to the roof at the edges.  In the middle it is just bubbly - you can just press your hand down on it and it will pop right back up.  I was thinking about just cutting it off at the edges and it would probably just peel right off.  I had researched some products and was thinking about trying out the elastomeric product call "Snow-Roof".....talked to two CM dealers and the best they could do about telling me about the epoxy was that the manufacturer had sent it to them (which was probably 6-7 yrs ago) - and CM/Cimarron hasnt been much help on "epoxy" :-)

If the roof wasn't properly prepared before the epoxy was added, its bonding would have been compromised, as you see with the results you are now experiencing. Before you add any other surfacing agent, you too, should first address this issue.

Elastomeric coatings are made by several manufacturers. There are differences in the products of quality and warranties. The coatings are as easy to apply as latex paint, and can usually be recoated without problems. Not only will they protect a fiberglass roof, but will seal it and reflect much of the UV, which eventually damages the gell coatings of FRP construction. A secondary benefit is the lowering of the roof temperatures, especially if the product is applied to a bare aluminum roof.

I would try to make sure it's just the coating that's come loose, and not the top layer of the roof that has delaminated. That was the issue with the material that was used on those trailers was that the sun would eventually cause the roof to delaminate.  

As long as you have a rigid substrate to work with, the entire roof does not have to be replaced. Once the epoxy or resin or whatever coating that has been applied, is removed, if necessary, the remaining surface can fairly easily be rebuilt by adding more materials.

If the top layer is delaminated, it can be sanded until until the laminate reveals a bonded area. If this weakens the remaining materials, an additional coating of mat and glass can be added to rebuild its strength. Holes or weak areas can be first reinforced and faired with a variety of materials. The original roof can provide enough strength, to support the new materials until they harden. It's fairly easy to recoat large flat areas with additional glass layers. Once the layers have bonded, the new surface is prepared for an overcoating of the same surfacing options as was previously discussed.

FRP construction and repairs in this case are relatively simple, and not overly expensive to effect. These larger repairs may not be necessary, depending upon what is discovered when the loose material is removed.

I think 2004 and 2005. You can call Cimarron and ask them. If you have the VIN, they will tell you if it applied to that particular trailer.
