Has any one repaired ceiling after leak near antenna , Ceiling has wrinkled at the seam . Noticed stain in light , appears the ceiling material is starting to bubble .
Probably not much help but from youtube videos, the only way to fix the ceiling material in RVs is to replace it. The videos were talking about how to tell if a RV had/has a leak. They said the ceiling pretty much always are damaged/stained if they leaked.
Maybe someone else on youtube shows their ceiling repair or replacement. Probably not a Lance TC, but maybe something with a similar ceiling method/material.
