What's wrong with these Velux windows?

[londoner123]

First time poster hoping to get some advice from those in the know....

I'm having a loft dormer conversion, which includes the installation of some velux windows on the slated part of the roof. There seems to be a serious problem with the way the windows are installed as they do not look level to the roof. The tiles seem to rise on a slant up to the window.

Can anyone suggest or advise on exactly what is wrong with the way they're installed so i can pinpoint this to the contractor? Many thanks in advance for any help

The flashing might be pushing the tiles up a little but it's hard to tell from this photo how much that's happening. The one on the left looks a bit too high.
Can you take a photo out of the skylights?

They have fitted the brackets too high on the frame, or packed the frame up past the laths.

Or not cut the tiles back far enough on the flashing, or cut the nib off, causing them to ride on the flashing.

Or not cut the foam filler piece, and just wedged it in, pushing the tiles up.

So what eactly are you saying Woody - crap job then.

You know the jobs been done wrong Londoner, so just bite the bullet, and tell the fitters that you're not happy with it, and would they please do it properly. More importantly, if they can't fit the velux windows correctly, how will they get on with the rest of the conversion.

I don't know about crap. But something is certainly amiss, and it could be one or several reasons for this.

Looks like they have used the wrong flashing kit. Also look like tile n halves which would make it look worse.

 

[Doggit]

But seriously though, experienced loft convertors shouldn't need to be advised that they haven't fitted the windows properly. What else does the OP need to keep an eye on. Where did he find them, who recommended them, have they demanded all the money up front, etc etc.

Probably over the stairwell or in a bathroom.

It isn't right for sure, Woody has highlighted all the options apart from possibly wrong flashing should be EDP for plain tiles

I have fitted loads using plains and have not had as much kick as is shown on the OP's Velux. The installer needs to fit the tiles with a certain amount of care in order to minimise the kick, as per Woodfillers points above.

Wouldn't fitting the brackets higher on the frame seat it lower in relation to the roof......?

Just sayin Woods...

 

[chappers]

shouldn't make any difference the flashing can only go as low as the battens

Not if they turned the frame over first to fit them.

Otherwise, maybe, just maybe.

Aren't there a couple of slots routed in the frame, and the brackets go in one or another depending on the tiles .... or something like that?

The last one I did was like that. Pretty hard to get it wrong IIRC - maybe they have some special circumstance they're trying to work around, like a shower room with restricted head height like you say.

I always thought a bit of kick was desirable - like you'd have on a verge or ridge end. Those seem a bit much and the brand new tile-and-a-halfs that draw your eyes don't help - can't you get some old ones from the reclaim yard?

 

[chappers]

you will always have a slight kick as the tile goes over the flashing, depending on tile thickness but it should be like in Nose's pics.
the correct flashing is EDP the one with the stepped soakers, which are generally pretty much spot on.
But things could be worse.

Correct. Some are colour coded (Keylite).
