Aluminum roof repair,,

Hi, Our old motor home has a flat one piece aluminum roof. The aluminum is getting more and more tiny holes that are from the aluminum corroding. I have been caulking up the bad spots as they show up. Is there something I can coat the whole roof with to stop the leaks before the camper is junk from water damage? It needs to be something that will stand up to standing water.

    My 1983 had a rooftop storage box. When I rebuilt the cabover, I discovered that the box would trap dirt and moisture underneath, which would turn acidic and cause corrosion. Only that spot had corrosion. My fix was to use U-Seal roof tape from Home Depot on the area, then I used Eternabond to double seal seams and all around the edges.

    My advice is to identify why the roof is corroding and evaluate a spot repair. Wash the aluminum roof periodically and it should last the life of the RV. If it has already gotten damaged all over, then a liquid repair would be my choice. Bus Kote is another really well known product worth looking into.

    if you plan on keeping it a while, get it rhino lined or similar.

    From what I am finding it looks like liquid roof is the best stuff. Pretty expensive though, at least to me it is.
