I paid around $100 bucks to have our coach's roof resealed about a year ago. They stripped all the old stuff off, cleaned the areas real good, and re-applied a quality sealant. This was done at every penetration except the 2 ac units. The air horns, two antennas, the sat dome, all the vents, sky light over the shower, ladder mounts, everything. I know this was done because I watched, and it took him all of an hour and 15 minutes to do.
