I've had 2 velux windows installed in an old slate roof.

The bottom edge of one is perfectly level, but the other one isn't. It's about 15mm out along it's width which will cause unequal distances between window pane and future ceiling plasterboard.

Obviously, it's going to look a right mess when I try to finish the inside plasterboard.

I'm thinking that the installer is going to say the rafters are sagging or something and nothing can be done about it, but they're not.

I'm assuming they're going to need to start from scratch to fix this. Is that the case? If so will a new flashing kit be needed?

Thanks. It seems they've included one rafter which is not in the same plane as the others when judging the position.
Anyway, what's the best way to proceed?
If I use equal depths of plaster board for the jamb extensions, will the slope be blended into the rest of the ceiling if I shim the plasterboard in places? Sloped ceiling is 380cm wide by 150cm. Windows are 98 by 78 and about 140cm apart.

Yes, it's top hinged.

I've just had my first chance to have a look outside in daylight. What's everyone's opinion on this? Should the flashing up the sides be covered?

Thanks. It's a new velux window. It doesn't leak but I can't find another example on the web that looks like that when fitted regarding the side flashing. The top cover isn't straight either and the trim on the bottom left is bent as well.

Regarding the 15mm, am I going to end up with the reveal looking like this?..

Also, looking at the bottom edge, the right hand side sits higher than the left. This corresponds to the lack of level on the inside. Surely if it was the old timbers that were causing the level to be out, then the window wouldn't sit higher than the slates on one side than the other? The bottom edge of the window would be parallel to the slates wouldn't it?

Yep. Sent the photo to Velux and got a report back in a few hours detailing all the problems.
Other one looks better/OK?
