I've just found a small leak in my tiled roof, after heavy rain one of the
timbers in the loft is damp & the same ceiling area in the back of a fitted
wardrobe has signs of some damp, probably over some considerable time.
The roof will be fixed ASAP, but i'm more comcerned about the roof timbers &
the effects of the damp.
Once dried out should i be applying something to preserve the timber/reduce
the risk of any rot/kill off any possible fungus, or am i being paranoid?

thanks
