Thank you , really appreciate this.
If only the ridge roll is used on the hip , and nothing else does it matter if no trays?

No.
Hip trays are there to support the ridge tiles due to the longer diagonal incremental spans between the roof tiles. They are not used on the horizontal.
Even with dry ridge, we always compo the ends and junctions....

Good practice though more important for larger format tiles.
The lack of trays will not affect the hips performance.
I have seen hip junctions capped like yours but a lot neater..how it is secured would be my question.

Noticed there is cold air coming in around the new velux that I've had roofers to fit is that normal or should there be no air at all ?

 

[Alastairreid]

Is there a vent bar in the handle?

 

[vw754]

Yes and it's closed , this air can be felt on the sides of the window

 

[Alastairreid]

Should be airtight around the window seals. Is the window sitting square within the frame? Does the bar click shut smoothly?

 

[vw754]

Yes sits ok , looks square from outside and inside , roofers said that until you plaster board it , it's going to get a bit of draught , bar shuts smoothly

 

[Alastairreid]

OK I assumed the draught was within the velux frame.
As your guy said, once the insulation and plasterboard are installed it should be all good.

Really appreciate your help (and everyone else on here)
Roofer said same , he said it will come from under the tiles , because there is no plasterboards or anything so it normal.
Thanks again mate really helpful and much appreciated .

Just an update..... roofers coming back Tuesday , he said he's going to put the flashing under the tiles and mitre the joint and seal it.
He said the guy who put flashing on top has done it because where he used work at his previous job ,that's how he was taught , and roofers apologised and said will sort it Tuesday as that's not how they do it.
