I disagree with anyone who says that standing water isn't a problem. My Dicor looked like new and still water got in. When water stands for ANY length of time, you are increasing the odds of failure of a sealant/seam. The proper solution is a properly sealed roof that has a good crown and no barriers to water draining off the roof.

At one time we tried wrapping the roof around the edges.

The radial edges wouldn't flex while going down the road then they would develop cracks in the roof. There are still some manufacturers that use the rolled over fiberglass roof but recently they have ran into the same issue with roof cracks.

Thanks for the info Josh - also if you're reading this I was always wondering on the new Forrester and Sunseeker if you guys have a steel backer underneath the front cap Transition for those screws to bite into ?

It makes sense that that type of fiberglass roof would have cracks if you try to roll it or really bend it at all - I have always wondered though is it that much more expensive to make a one piece fiberglass roof just like the front cap But the whole roof ? Or is that more of an issue with it not flexing and getting cracks ? Or another thing I have seen there are RV repair shops around here that have replaced the roofs with a sheet of aluminum which is easily bendable and is a lot stronger than fiberglass - Plus it will not crack and is a lot more resistant to all the elements - I am sure aluminum cost more than fiberglass though

I assume you are referring to me - the dicor is not there to seal anything it is simply to displace the water that would otherwise pool in the corners - I can see the top of my RV from my deck and every time it rained there used to be water sitting in all four corners for at least a day even in the hot sun - after I put all the dicor there the water can't sit because it has nowhere to sit it has no sealing purpose it is just simply to displace the water - i'm sure it will crack and deteriorate but it will still be serving it's purpose
