How bad is this roof job?

[Jonno67]

Got my entire roof redone at the end of last year. All looks great from the outside but I’ve just ventured up to the attic and you’ll see from the pictures how the job was left.

OSB boards don’t meet, there’s damp everywhere and mould is beginning to grow. Going to get in touch with the roofer and ask him to come round - he subcontracted the job out so wasn’t on site during the work.

Could the damp be caused by condensation from the warm air rising from the house? Never had an issue with the old roof but there were holes in the tiles which probably aided ventilation.

Any advice on how to deal with the damp and roof would be greatly appreciated, never had a roof done before, so nothing to compare it to.

Cheers!

Why does it have sarking boards?

are you in Scotland, sarking isn’t too common in England. I assume it’s a conventional tiled roof.

If you had your roof redone, did they do the insulation at the same time?


Your roof should have ventilation - so you need to make sure your loft insulation isn’t blocking eves ventilation.

You also need to seal and insulate the loft floor to minimise warm air getting through into the loft…especially from a bathroom or airing cupboard.

Thanks for replying. Yes, I'm in Scotland and it's a conventional tiled roof.

They didn't touch the insulation on the loft floor when they were here. That's been down since I moved in 6 years ago. I'm confused though, how do I seal and insulate the loft floor without blocking eves ventilation?
