    Roof Bubble

    I’ve been thinking about how to ask this for a couple of days. I have a roof bubble forming right at the front. It is half the width of the trailer and extends back about two feet now. 500 miles ago it was only about a foot deep. I am going to replace the roof with flex armor (the guy in Denton) but my appointment is 6 weeks out. I want to head north, way north, to comfortable temperatures until then. So I need to do a temporary repair.

    I’m thinking a making a couple of slices in the TPO. Then using a Loctite spray adhesive to re-attach it as much as possible. Finally I'll re-seal the slices with Dicor. It seems like it would work, but the idea of cutting the TPO bothers me, so I’m looking for other ideas before I commit.

    Thanks

    Check the transition from the front cap to the roof. I'll bet there is a place where wind is getting inner the TPO. My recommendation is to try to squeeze as much of the air out as possible, even if you have to make a slit in the membrane right at the front cap, then run a strip of 6" wide EternaBond from side to side, overlapping the Dicor, front cap, and membrane.

    Several of us have done this as a preventative measure.

    Morning MoonShadow, my TPO is starting to balloon just behind the front cap. The termination strip is tight and the sealant is now split. As I understand it low air pressure (i.e. 65mph + high head winds) passing over the roof is lifting the TPO and stretching it. Do you have any pictures of your fix? thanks, Frank.

    From what you're describing, I think a full-on intervention is needed, i.e., gaining access to the entire area that is no longer adhered. With that kind of area loose, it won't get anything but worse. If this means cutting the membrane to re-glue, that's what has to be done. Resealing with the appropriate self-leveling sealer is fine - and a much better solution than having that large an area not adhered to the roof. A couple of cautions: determine whether you have a TPO or EPDM room membrane (GD Customer Service can help with this with your VIN) to make sure you use a compatible adhesive and the right self-leveling sealant. You don't want an adhesive that can damage the underside of the membrane.

    Thanks Rob, it is just now forming, the area affected is still relatively small. about 4" wide and 3' long right behind the termination strip. geotex1 provided me with what it will take to do a permanent proper repair. I am holding two appointments, one with a dealer (Feb 2023) and one with FlexArmor (Apr 2023). Just trying to mitigate it to finish off this season.

    Here is the thread I started (you can find them using the search function) about the preventative measure I took by putting a 6" wide strip of Eternabond down across the front and the back of the roof membrane where is was gooped with the self-leveling sealant.

    Again, this was a preventative measure.

    Will FlexArmor spray over the existing membrane or remove the membrane before spraying?

    The old membrane is removed, cutting around the A/C and other"permanently" mounted devices, usually most of the sealant comes up with the TPO removal; trim is also removed. Then FlexArmor is "painted" on the roof. At least, that is what I've seen in a couple of videos I watched about a year ago.

    You may want to make sure that they will remove it. I've seen a video recently where the customer wanted it removed and they sprayed over the existing with bubbles under it. They told him it didn't need to be removed after the fact. I'd just check to make sure you are on the same page if removal is what you want.
