I bought this 5th wheel 6 years ago. It had a roof repair using just Dicor along the edge of the roof which has been water-tight for the 6 years I have owned it. The previous owner must have dragged the trailer along a tree branch or other object. It is along the top of the edge of the roof (just before it bends over the edge and tucks under the molding). The repair has come loose in two places (one 4 inches wide and the other about 3 inches wide). I need to address this before the winds and rain come.I had a mobile roof repair guy come out today and he took one look at it and said the only fix is a new roof (quoted $7500). The rest of the roof is in perfect (age-appropriate) shape. He said there is no repair he can make that would hold up to the wind.OK. So, I agree this is probably the worst place a roof can be damaged. But, I'm not so quick to give up on the possibility of a repair. It seems to me that the molding could be pulled back, and a wide (e.g. 12") roll of eternabond tape could be applied to the length of the damaged area with 2" or so overhanging the edge. Then roll it over the edge and re-attach the molding over it and trim as necessary. Is there any reason this wouldn't work? Has anyone had this kind of damage and successfully repaired it?

Prior owner made repairs that lasted at least 6 years. Make that repair for another 6 years.

Based on your description, I’d go with 12 inch Eternabond tape.

I'm pretty sure Dicor alone isn't going to cut it this time.But maybe I could just carry the eternabond to the edge of the molding to avoid removing it and pulling it back. I'm just not sure there's enough surface there over the edge to stick to. I think the right way would be to go under the molding like the original roof material.

I have a similar tear along edge on my FW, I repaired with Eternabond tape without going under the moulding on side, then applied self levelling Dicor to edge has been there for several years, was told also that roof had to be replaced and insurance not willing to pay more than 50% Frank

I eventually put a new roof on it. But, it didn't cost anywhere near $7500. More like half of that. Inflation?

Seems like anymore people will catch you at a vulnerable position unable to fix things yourself and just throw a ridiculous price on it to see if you will take the bait. If the repairman has other work lined up he will put a high price on you to see if you bite. If you do he will put other work on hold and go do the ridiculous priced job. Go find someone with less workload and get an estimate. Get on youtube and see how others have fixed problems like this.

I did the same, caught a branch leaving the house, right at the bend. Used 4" eternabond tape right down to the little rain gutter. Done a number of years and many miles ago and still holding tight. That stuff is just about impossible to remove once secured in place.
I'd remove the Dicor as best as you could and cover the entire area with eternabond tape and call it a day.

I'll add my vote for using Eternabond as you described. I've been using it for over 20 years on 5 different motorhomes around roof vents, a/c flashing, roof seams and front and rear caps. Never a leak on any of them.

No need to remove the molding. Just use the Eterna bond tape up to the edge of the molding. First remove as much of the Dicor as you can. Install your Eterna bond and cover edges with fresh Dicor. You should be good to go. Good luck.
