Velux window removal?
Anyone done it? Removed one and made good the roof?
I have one in France and water gets around the outer "guttering" under the tiles, gets through the roof, flows down the outside of the vapour barrier and is wetting the edges of my newly installed plasterbaord, turning it black.
Ideally, being as we now have two windows in the room with roller shutters, I'd like to remove the Velux and replace the roof as solid.
Is it do-able?
I'm quite handy, but don't want to make it worse.

Vapor barrier shouldn't be touching plasterboard. it should go as far down as the guttering. There should be an eaves tray on outer edge to guide water into gutter

The vapour barrier is an internal one I put over the insulation and under the plasterboard.
Not sure about if the flashing is the correct type, installed correctly etc, as I didn't do it. It's quite shallow....... And the foam upstands lasted about a year

Vapour barrier shouldn't touch insulation, be installed under tiles on battens or cross battens. If youre fitting insulation between rafters then an air gap below the barrier a least 25mm ideally 50mm. This is dependent on rafter depth.
a breather felt like Tyvek is ideal. it allows water vapour to escape but won't allow water to penetrate if fitted correctly. It sounds like you need a re roof to do the job properly
