    Thanks in advance for any help on this.
    I am a long time Coleman owner and I am not one to move from rig to rig. I have a 1992 Arcadia that I bought brand new in Jan 1993 and we have used it well over the past 25 years.
    With that said, I am aware of all of the leak and repair issues with it's aluminum skin and I have had to do some reconstruction.

    I have Just purchased a 2008 Fleetwood Niagara form the original owner. This rig is in excellent condition except for one concerning thing, soft spots in the ceiling.
    Just forward of where the Air conditioning would be located there is an area about 12 inches square the ceiling is soft if you push on it. Also further forward on the ceiling there are 3-4 bubbles between 1 and 3 inches around.

    The roof appears solid with no voids and as I understand this roof is a 1 piece fiberglass unit.

    Questions;
    Has anyone seen this before on this roof type and what has been the result?
    What is the make-up of the roof under the fiberglass (foam then luan, then vinyl?

    Hope I didn't get myself into a huge project. Previous owner super nice and honest but was pretty clueless regarding maint and the workings of his equipment.

    Ideas?

    Than

    I have an '08 Bayside with the same roof as your Niagara. The soft spots are probably caused by a leak around the A/C unit. The gasket is probably shot, or wasn't replaced before it started to leak. The time water got in my roof was from an old gasket and a small crack from the corner of the opening. It was an easy repair and no more leaks! (the gasket is ~ $14.00 from Amazon) The roof is as you have surmised, fiberglass, Styrofoam like foam, luan with a coating.
    If you pull the ceiling off then it is a project. When you pull the A/C unit, which you'll have to to replace the gasket, you may be able to let the ceiling dry by itself and work around re-gluing the ceiling panels. I did not have to pull my ceiling panels, just let them dry, and kept a small space heater going to help. But probably you may want to remove the front couple of ceiling pieces and and dry the inside of the ceiling. You may not need to replace the foam and the glue holding it to the roof is probably OK. Just need some pop rivets for the door track and a new paint job/wrap for the new ceiling panels. (might be a good time to look at vinyl wall art to wrap the panels. How cool would a starscape be on the ceiling :) )

    Thanks for the response.
    This one doesn't have an air conditioner so I will have to do a really good look at the roof to see if there is a void/crack I can find.
    But thanks for confirming the roof components, it appears that regardless of the outer shell (ABS, Aluminum, Fiberglass, etc.) Fleetwood/Coleman used the same foam/luan/vinyl ceiling. Thanks for your recommendations for repair

    With no A/C it's probably leaking from failed caulk from the corner caps or track/side walls. Still the same kind of fix. Good luck!

    Get up there and take a really close look at that roof. I found 2 small holes in mine (about 1/4 inch dia), Filled with epoxy and coated my roof with a clear sealer that is UV stable. Fleetwood also did not seal the side caps / roof rack tracks to the roof, they relied on the sealing of the Filon top to the Filon sides under the tracks (you can't see it), I sealed mine to the roof with Sikaflex urethane caulk.

    Thanks, Sikaflex is always a good choice. Used it on my 1992 Arcadia.

    Thanks for the advice gentlemen, I do appreciate the help

    It gets even better than I expected. After picking up the trailer and setting it up for the first time at my place we noted all of the ceiling spots, cleaned off the roof so we could see better and HOLY CRAPOLA! The roof has small cracks all over the front 3rd of the trailer.

    What did you use to seal the top? I am not sure I want to go the Grizzly Grip path but may have no options

    Are they hairline cracks or larger?

    I used a product called Seal-Krete. Stuff is as thin as water but it penetrates, sticks to anything that is reasonably clean, it's UV stable and it's commonly used as a binder so anything sticks to it.
    Cleaned and scrubbed the roof with TSP.
    Put 1 coat of Seal-Krete on the roof making sure the stuff runs under the side rails and let dry for 30 minutes.
    Sealed the side rails to the roof with Sikaflex Urethane caulk (Fleetwood doesn't do this).
    Rolled 2 more coats of Seal Krete on with about a 2 hour wait between coats.
    You could roll any thing you want on top after if you wish, I didn't but other than the 2 holes I patched up, I only had a few hairline cracks.
    I repeat 2 coats every year in the Fall, makes the roof look line new.

    .
    Sounds like a plan. Doing maint every couple of years keeps you on top of any potential issues. What Seal Krete are you using? I have only used it on concrete garages and patios?
    Thanks for all the good info.

    The same stuff, comes in a gallon jug and states can be mixed with paint but the primary purpose is for concrete. Also covered my PVC bike rack to give it UV protection. Stuff sticks to everything.

    BTW, I may cover the Seal Krete with something some day but it works great as is. Also made my weathered old TT filon outside walls look like new again. Only did that once but after 5 years it still looked good when I sold it.

    Hi! I have the same issue with an 07 Fleetwood Niagara. The roof looks rock solid but I suspect the AC gasket is probably defective. Do you know if the Fleetwood Niagara roof is 1 piece? There is that track on the upper sidewalls and I'm not sure if that would cause a leak as it seems like sitting on top of the 1 piece roof.

    Hi Kevin! I know this is an old thread but I hope you can help me with some answers. I just purchased an 07 Fleetwood Niagara and I have the same problem of some roof leaking. I suspect my AC gasket is defective but I noticed also some signs of roof leak on the rear part. Have you fixed the roof problem on your camper? Also I am leaning towards applying an elastomeric roof coating but also have second thoughts since the roof looks rock solid. Thanks for any response.

    Welcome to the forum!
    I did fix the leak issue, and yes I am absolutely sure after the deluge of rain we got this winter in So Cal:grin:
    I used Grizzly Grip https://www.grizzlygrip.com/camper-top-repair and sealed my roof. I do not have AC but have been told by many that the gasket is a culprit for most leaking.
    On your 2007 I believe you have the Filon (fiberglass) roof with tracks on each side. Coleman laid down a strip of Butyl tape and then put the tracks on top. This fails after time.
    So what worked for me was clean the roof with acetone, Grizzly Grip, 2 coats, and then applied Sikaflex caulk to ALL of the seams.
    If you have AC you are going to need to pull it off and after sealing the roof, put it back on with a new seal.

    I finished mine about 2 years ago and is leak free. I have been traveling for business non-stop so I am just now repairing the damage to the ceiling. I have just pulled down the bad areas and I am lucky because everything is dry I just have to replace sections of the Luan and put new vinyl up.

    Hope this helps, ping me if you need anything else.

    Thanks Kevin for the reply. I have started sealing the roof I'm using gorilla heavy duty construction adhesive and will be sealing with Rust-Oleum elastomeric roof paint. I've also ordered the AC gasket and hopefully this will stop the leaking. Thanks again for the valuable information.

    If you buy the AC gasket kit from Colemanpopupparts, it will include another foam block that sits further toward the back of the AC unit and helps to support it so it doesn't sag toward the back. That's what happened with mine and it caused the front of the AC to raise just a bit which caused the leak.

    I have the same issue on my niagara. I didn't think to take the a/c off and look for a seal, I was planning on scrubbing the roof and using a sealant and caulking the seams...
    I will have to get up there and check for the a/c seal as well. It's getting late in the season so I may end up pulling it under the car port or throwing a giant tarp over it for winter.
