    Do you mean do a frame on top to help prevent sag? I have been thinking about that. SOmething like plates/bars bolted to each corner, then when you run the lengthwise bar you run it a little shorter in the middle supports to suck up the sag.

    Also nice job! you got lucky with the easy peal abs. Mine had to rip and chisel off here and there, destroying some sections of the foam/fiberglass.

    my thoughts were to remove the roof altogether and make a Rectangular frame with Cross pieces using aluminum square tubing. Runs about $21 for an 8 foot length. Obviously would need many of these. Then skin it with thin plywood. That Should be light enough for the Lift system, but stronger than the saggy foam roof I currently have.

    we have a 2000 Coleman with the ABS roof. it has a couple of cracks but its otherwise solid. Reading here i am going to try some of the products to seal the cracks. I was member here years ago but just came back after getting the pop up camper itch to repair things again. I sold my old pop up a few years ago.

    I decided to try silicone roofing paint from Lowe’s. $60 For 1 coat (I used the full gallon) and 1 hour of work. I’ll let you know If it doesn’t hold up but so far it looks good to me.

    I can't vote because there is no "I have ..., but haven't gotten around to fixing it yet."

    I have a new to me ‘97 Coleman Santa Fe with some pretty significant cracks, and a real bad sag. I’m considering removing the ABS roof all together, filling in cracks with Bondo, and re-sealing with bed liner, but I want to fix the sagging/ warped roof before I do all that. No leaks, pup is kept covered when not in use, so the inside has always been dry (I’m in California). Has anyone fixed their warped roof and have any pointers? I don’t have a lot of experience in RV repair, but I’m hoping it won’t be too difficult. TYIA

    I was thinking the same thing! I love your process, and I’m gonna give it a try once I can fix the sag in my room. I’m lucky that I don’t have A/C, so no chance of a leak there. Thanks for sharing!

    I have a 1999 Coleman Niagara, my roof isn’t sagging but has a few small cracks along the front and rear edge near the bottom. Also has 2 crack approx. 6” on opposite sides just above the roof latches. I was curious if these could just be fiberglassed or bondoed and the just painted?

    I removed the outer layer, it just kept cracking and there wasn’t any “fix” that was going to stop it. I gave the top 4 coats of KoolSeal and another 2 coats this year. I installed usistrut on the inside to support the roof and keep it from sagging. After seven years without the outer layer, the top still looks good.

    What they said, anything other fix is just buying time untill it compleatly delaminates.

    I know of those who have tried this repair with fiberglass and it didn’t work. The fix right now is to find ABS plastic and melt it down with MEK. I tried that but the problem is you will FOREVER be chasing cracks. You fix this one and another pops up.

    My Bayliner cracked like that. When I went to remove it completely, it had delaminates from the foam core. The entire top came off in one piece. The foam core, after I cleaned the foam core off it was in perfect condition, no cracks. It has a rather hard layer for a foam based product. I removed the roof seal and have coated the core 4 or 5 times. It’s been 7 years since I removed it and all is well.

    Those cracks looks fixable with bondo and fiberglass cloth/resin to me without needing to rip the whole ABS layer.

    You can fix it like that, but it will not last. Especially that one that has allready been patched with eternabond and who knows what else and painted. Mine wasn't even that bad, and it looked perfect after i redid it. But 1 year later it started recracking. It just dosent last.

    I used Unistrut. To make this easier to understand, give me a day or so and I’ll have pics for you and I can explain what I did.
