Does roofing sealant work on aluminum roofs and if so, what is the best brand to buy?
I have a 1988 Fleetwood 5th wheel trailer with an aluminum roof. The roof appears to be painted with a grayish material that is flaking off. There are several places where the rain leaks into the trailer. It also appears like a former owner tried to use silicone in several locations. Before applying anything new, I will use in industrial stuff bristled floor brush to remove the flaking material.
I assume all aluminum roofs have seams at regular intervals. My RV around 7 seams in the roof. I am thinking that leaking is mostly at the seams, because I notice a seam-crack in the "gray stuff" near the place with the worst leaking. Expansion/contraction could be a problem for the seams, because the RV is parked in direct sunlight. Using a temperature probe today, I measured 147F while the shad temp was 90F. A few weeks ago the shade temp was over 103F. When water was sprayed on the roof and I could hear creaking during the contraction.
The last time it rained, I covered the outside of the trailer with 2 mil painters tarp. The wind was not too bad and that kept out the rain but for a few drops.
