Hello, I have a 85 Newmar Kountry Aire, the aluminum roof has waves in it, were the adhesive under it appears to have failed. It is not leaking for I can not see any water stains in the interior. It appears to be a total of 4 panels that cover the roof, they are only riveted using the outer edge of the panels. I thought of running screws inside of each panel and resealing in attempt to keep the aluminum sheets flat.thge roof feels firm so I assume the wood under the sheats are good and should hold the screws firmly. Has anyone else ran into this problem or have any suggestions for me? Thanx in advance.
