I was not talking about seams...rather the membrane. I have been in construction for years and know of no product used on commercial roofs for the membrane....neither do the roofers I know. Sealing the seams of course....they should be checked and touched up every 6 months. As for eternabond....never again
The thickness of a commercial roof is a lot different then the thickness of an RV roof. I'm sure you've carried a roll of commercial roofing up a ladder and know how heavy it can be.
The much thinner membrane on an RV will start to develop fine spider cracks after about 10-15 years. At that point the roof seems to hold onto water longer. Many put on an Elastomeric Roof Coating that can handle standing water to help extend the life of the roof. It will also keep the rig cooler in the summer.
Nice recovery of yours on the sealing of the seams. Funny though that seams are glued and the edges are just touched up with a black rubber roofing caulk that can be bought at any hardware store for about four bucks.
