    Ive just been in the attic to put the crimbo decorations away and noticed that the ceiling is damp to touch and all the insulation is wet, not soaking but wet.

    Its my 1st christmas in my 1st house and never come accross this before, there are no signs of leaks so I am wondering if this is condensation, does any one else have this problem? if it is condensation what can i do about it?

    The attic floor has almost a foot of insulation on it so the house is very good at retaining heat, im wondering if this is whats causing the problem

    Condensation is generally widespread, whereas a leak would usually be more localised.

    I had exactly the same thing a few years ago. The cause turned out to be a vent pipe that should have been connected to an outlet in the roof, but had been left unfinished when the house was built. Can you see an open ended plastic pipe anywhere in the area with the problem?

    If it isn't that then it could simply be that the area needs more ventilation. You can get roof tiles with air vents fitted. In fact I had that done before I established the cause of my problem, and it didn't cost too much.

    I don't think it can be anything to do with having too much insulation - unless that has caused the air vents (where the floor joins the roof) to become blocked.

    If all else fails contact a reputable roofing specialist and seek advice. And with a problem like that, the sooner the better.

    Once you have found and fixed the problem let the space dry out naturally, or get a dehumidifier. Using a heater is not recommended as it can warp the wood.

    same thing happened to me,

    it was just case of needing more ventlation in the loft, they took out a slate and swopped it for a venting cap

    good luck

    Do you have any water tanks in the attic?

    Recently found water coming through ceiling in my spare room, but on entering attic no sign of wet inside roof. Water was coming from (metal) water tank which was on point of letting go completely! Plumber said that bottom of tank (and the CH header tank) was "paper" thin and I was close to having mains pressure water pouring through. Both tanks now replaced with new plastic equivalents and a combi boiler installation will follow soon which will lose the tanks completely.

    If you have a standard Central Heating system with header tank, etc. it's possible that the boiler may be set to high or the pump speed may be too high. Either of these can result in a slow but steady stream of steam from the open vent pipe above the header tank. The steam then condenses on the colder roof.

    thanks for the responses, it looks as if the air vents where the roof meets the walls are all blocked with the insulation, i hve moved the insulation and will see what happens.

    I dont have any water tanks up there and it looks like its all over the roof so condensation seems likely. I will look at a venting tiles if this does not sort it

    Might be worth leaving the loft hatch open a few inches to encourage the air to flow through for a few days. The warmer air might help the loft to dry out (assuming your loft hatch isn't in the bathroom, in which case it could make things worse).

    Now that you have cleared the vents, I suggest leaving the attic hatch door open for a few days to aid the air flow.

    GaryB got his message in just before me..................

    Or, if it is really bad get a dehumidifier. B&Q and places like that sell them. They are also useful in the summer when humidity levels are high, and they collect a surprising volume of water.
