I'm new to the forum and RVs. We just bought our first RV - a 2003 Jayco Kiwi M23B. To my untrained eye it looks very clean. The roof, walls, and floor are solid. The previous owner said he resealed the roof as needed, but I'm going to assume he never did. I was thinking that I would replace the A/C seal, remove old sealant on roof and reseal w/ Dicor, and caulk the sides. I've been reading about liquid roof and was wondering if I should just clean up the old sealant and coat the roof with this stuff to be safe. The roof looks ok, it isn't too chalky. Is it nearing the end of its life? Is there any reason not to coat it with the liquid roof? It has been raining like crazy here in TX for the last few days and I don't see any signs of leaks so it seems to be currently sealed. Is there anything I'm missing? Is this overkill?
if I replace the A/C seal is there any reason not to seal the edges of the roof where it was cut for the A/C so that if there is ever a leak it won't be absorbed into the roof?
Membrane roofs generally last 15 to 20 years or more. If the A/C is properly sealed to the roof with the new foam seal (NO CAULKING!), it won't leak.
Sealing the roof is important, but also seal the other intrusion points such as the TV antenna, vents, clearance lights, windows, vents, tail lights, front cap, etc. Caulk or EternaBond. Keep us posted and ask if you need anything!
