Wondering about my 1982 RV's roof, it needs to be fixed.

My 1983 has an aluminum roof and I had to repair a section under a plastic top box. Anodic corrosion had pockmarked holes all over the front of the aluminum skin.

My solution was to use USeal-Band roof repair tape from Home Depot and Eternabond. The U-Seal was the most affordable way to cover a large area and I used 1" strips of Eternabond to seal the seams between strips and the outer edge of the whole repair area.

If you need to seal individual cracks in the roof, clean with acetone or Eternabond prep. and then fix with Eternabond. Use a metal roller.

If you have to repair the entire roof because it is damaged all over, then there is something called BusKote that is specifically designed for buses and RV's (both vehicles that live outdoors and tend to have sectional roof's).

here's a picture of it.

Wow! Thank you, that's great info.

Is that a chassis mount? Looks good. Would be worth the time to get it tip top shape IMO.

We can't see the top but just from the picture it looks like the joints are leaking. If you have a one piece Al roof and the roof is not pitted through or cracked the only place it can leak is around the cut outs for skylights, vents etc. Being corrugated on the side walls I think I would try caulking there, and either caulking or eternabond type tape on the flat top.
