Could you have water leaking in from the roof??

Hi, thanks for the reply.

We've had builders around to have a look and they didn't see a leak. We have this problem in all 3 of the bedrooms in our house. We've had airing tiles put in as well, which doesn't appear to have helped the situation. The markings are only getting worse over time and it could end up costing us a foretune!! (not to mention it looks a mess)

Looks to me like condensation. You may have a gap in the loft insulation in the corner and around the edge where the water in the air condenses and then grows black mould in the coldest spots.

Take a look in the loft and top up the insulation around the edges and in the corners and make sure it is well tucked into any gaps. Keeping the bedrooms well aired and warmer will help too.

If you haven't got cavity wall insulation, that will help as well. Most Councils do schemes so it doesn't cost too much (and top-up insulation for the loft to get it to 270mm).

It looks like condensation. I had this problem it was caused by lack on insulation in the roof at the ends near the walls

Cold the insulation be wet? If so, would this have to be replaced, and who would do this (roofer, etc).

Yes it can be wet. Best thing is to clean it with anti fugal cleaner allow to dry opening windows for a day or two when weather is nice and dry then paint but you may need some insulation or at least try and not dry things on rads, have showers/baths without opening windows for an hour or so

You can get anti condensation paint made by INternation and yes it does work in mild condensation

I had the exact same problem some years back it was made worse when loft got insulated but the left large gaps near the edge. I went up put more in and pushed insulation in the gaps with a piece of wood. I didnt have this problem in the 2 years after but I now moved house

It was so bad I had environmental health around it got on a wall into warddrobe and damaged clothes

Another thing with condesation you get less in a warm room as warm air can hold more water, you could increase heat, have more insulation or use a dehumifier or have a window on trickle vent
