Last night we had a leak. Rain water was coming around the vent over the upper bed in our Solera S 2011. After inspecting the roof, there is no damage, so I think that it must be coming in from around the forward vent sealant, landing on the duct, and migrating a foot or so forward to emerge around the vent. I don't see any cracks or obvious entry points in the sealant, either...
First, any suggestions on what else might be causing the problem?
Second, any suggestions on a sealant to reseal the vent?
