Water on inside of roofing felt

[neil1203]

I've just been up into the loft to retrieve the xmas decs and noticed that the underfelt on one pitch of the roof had water droplets on the inside.

Just to explain that it's a pitched/tiled roof with underfelt and a north/south aspect.

It's the northern aspect that has the water droplets and they look almost like condensation droplets. I've had a feel into the gaps where the felt overlaps and it doesn't feel wet although I can't feel that far in. The southern aspect is completely dry.

Could this just be condensation or is it an indication of something more serious.

Cheers
Neil

99% condensation

Is it well ventilated?

It is as been said condensation so just make sure your eaves in the loft are not stuffed with insulation they must be kept clear for ventilation which reduces condensation it won't stop it.

I have cleared eaves and felt lined roof and have minimal condensation I'm afraid you have to live with it as you cannot completely stop it.
