a big run of felting has come off the shed roof. ive tacked it back down for now. Adding more layers over the top seems a half arsed solution compared to stripping it all off and starting again, but, its winter.
I would replace as soon as you can be arsed/it dries out as you don't want to trap moisture underneath and rot the roof. Tarpaulin would be an acceptable half-arsed solution if a) you can secure it and b) you plan to strip the felt soon anyway.
