So the material I am removing, (according to my build sheet it is rubber) is thick and in very good shape. Where I see the failure of the roof, NEWMAR did not place additional bracing along the outer edges of the AC units. Because of this, there was not a firm seal along the edges and eventually allowed water to get in.
I will be adding bracing between the roof frame work that will support the ACs one all 4 sides. There will be no antennas, horns and for now solar panels on the roof. I removed the luggage rack as well.
If I add a antenna, it will either be attached to a mirror frame or to the side of the coach.
My coach has aluminum sides that curve over the top and meets the roofing material on top. It appears that Newmar butted these to together and held them in place with a retaining strip with sealant and thousands of screws. I know I am not a engineer, put I see damage along this rail. I am going to sandwich the filon under the aluminum with sealant between them and under the retaining strip, then cover with more sealant and maybe tape. I am using a sturdier rail that I got from one of my customers that builds enclosed trailers. Like the factory piece, it is a [ shape. Newmar installed it flat side down. I am thinking ( since it is more robust) installing it flat side up, to give it more clamping force.
I may tape off the retaining rails and apply a 4" to 6" wide liquid rubber roof coating material to that area.
I also want to build some dams around the AC unit to divert water away. Probably do that out of 1" aluminum L angle metal. And just glue it down. Seal the top against the AC unit.
But 1st I need the clouds to go away so I can remove the trap and get back to work.
I STILL hate lap sealant..
Have only about 500,000 more screws to remove.
