Roof Felting
I'm in the process of reroofing a small shed and have reached a bit of a dilemma.
I've replaced the wood, however it then starting raining hard the other day and I left it unfelted to do when it was dry. Now the forecast looks
poor, I'd like to finish it but laying felt on damp wood doesn't seem like a good plan as I'd imagine the moisture will get
trapped.
So is it best to leave it unfelted and wait until the wood has dried fully (who knows when that'll be!) or felt it with some moisture in the
wood to stop the shed getting damper now? It's 18mm OSB if that makes any difference.
Thanks
Oli

Was the OSB conditioned ? If so you should be able to felt it.

I'd do a temporary job, with the felt, if you've enough or some cheapo visqueen (sp) spaced at 20 or 30mm from the wet roof, that way you
will prevent further water ingress and allow the timber to breath and dry. Then do the job properly in better weather / when its dry.

Just felt it and it'll be fine....
I'm a roofer by trade and we sark tiled roofs up here (NE Scotland )with it above the trusses. Sometimes the OSB sits nailed on the roof for
days before it's felted and the worse case scenario is that it'll swell a little, but it won't ruin the integrity of the board.

Let it dry out naturally (no added heat and it should be fine)

tarpoline it for now and come back to it when the weather dries up.
tuck the tarp under the wood and nail in with tarp nails and put card on the corners to stop it splitting the tarp.
the felt maybe ok if the wood dries out but may rot.
