punctured the roof on Thursday, Rained like heck on Friday, got water in the coach. (I covered with tarps) I patched (on Sunday after two days of sun) the 7 obvious holes with Eternabond and caulk. Rained like heck again (following Saturday), and got some water in the coach again thru the heat/air return ducts. No idea where it came in. Resorted to insurance claim. (ins adjuster and repair shop both liked the patch job).
They replaced a small section of the roof deck, and then double decked it (std practice apparently, both repair shops). No sign of water in the roof structure, insulation, or ceiling panels.
Only replace membrane, no patching allowed.
