How to dry out loft?

Hoploz

OK so we laid loft insulation last winter, then boarded it all out, leaving a gap at the edges for ventilation, but then filled it with boxes and it suddenly seems to have gone all mouldy and drippy wet on the top of the ridge on the felt

I am assuming we are at fault for stacking the boxes too near the edges stopping the ventilation. Also we've had an extension across the back so we've had wet bricks and plaster in recent weeks as well which I guess won't have helped. Also a storm on the weekend the roof was opened up great fun)

Question is how to best dry it out? Should we use a dehumidifier or will that dry it out too quickly? Is just leaving the loft hatch open enough? Don't want rotten joists and a new flippin roof!!

Thanks for any replies.

Do you have any vents in the roof to the outside?

Google "Roof Vents" to see an example.

I mopped the worst of it up with towels, then left a couple of desk fans running

check its not also being caused by steam from an expansion tank you may have in the loft

Don't leave the loft hatch open! Unless you live in a fridge leaving the hatch open will let more warm air into the loft and that will condense when it hits the roofing felt. You'll have more condensation. A dehumidifier will probably be your best bet although you could have a look at increasing the ventilation capabilities of you existing roof. You can get screw in vents that you attach to the soffit. They are dirt cheap and 0 running costs.
