    Can anyone tell me (just by looking at these pictures) if I have a damp problem from outside or inside the house?

    This paint started bubbling up and blistering in May and we haven't found the cause yet. The wall is an external breeze block in the kitchen below which there is a kettle used to make the tea. My parents who's place it is don't think it's caused by steam because no problem has occured in the last 6 years.

    The roof is flat, felted and sloped downwards to wards a gutter on the outside edge which overhangs the wall by a good 12-18 inches. As seen by the pictures, the coving is intact and not showing any damp at all - it's just the wall above and around the top inner edge.

    As you can see I have painted over some damp seal to see if it made a difference where some plaster was peeling off but I don't think it has. :cry:

    I thought about the window and gutter too but the roof extends past the wall by at least 12-18 inches so there is an overhang. I would have thought it impossible for any water to make its way into the the window from the front. It is fitted flush with the wall but due to the overhang I ruled that out.

    Still confused what is going on. I'm not able to take any more pictures from outside as my parents are in London and I'm based in the Midlands. :(

    If the felt has become split where it turns to the overhang, water gets in and runs back......then becomes absorbed by the nearest absorbent material, I guess.
    Again, check for gutter leaks or overflowing, and the condition of the sealant between the window frame and brickwork needs to be perfect.

    Finally got this sorted at more expense! :(

    The flat roof felt above was cracked in several places with water collecting above the window, hence the damp. It's all been refelted now but there are no stones on top. Is it worth brushing on a layer of stones to protect from heat damage?
