loose Alpha TPO roof beside fridge vent on roof

Question

I just finished re-sealing the roof with Alpha 1010 sealant, and noticed that between the refrigerator vent and edge of roof, the TPO membrane seems to not be glued down. All other areas seem fine, except there.

Any ideas what I should do? Bury it in sealant? Layer it with Eternabond from good area across this area? Or maybe its not a problem and I should forgetaboutit.

How big of an area are we talking about?

Many roofs are not glued down on the outer edges. If there are no obvious tears in the membrane and the membrane wraps over the edge I would not worry about it.

The only time they do not install glue is ON the radius from the roof to the sidewall IF the RV has radius instead of a 90 degree edge. The reason they do not on a radius has to do with the radius does not absorb the glue like wood and will cause discoloration below the rubber. Doug
