Best fixing for roof window trimmers.

[Watshot]

Hi,

I don't mean the standard practise, what I am doing is increasing the height above the rafters by about 100mm to accommodate a warm roof (pitched). The over rafter insulation plus the counter battens means I have to add timber to the top of the rafters to lift the windows to the new height.

I don't think smacking a nail through that kind of depth would work, so would you rely on careful skew nailing? Or drilling and counter sinking screws or something else?

I just get the impression that trying to hold a piece of timber on top of a rafter whilst skew nailing it accurately is going to be a challenge! So just checking with you guys whether I'm missing something first.

Many thanks.

get an impact gun and screw using say 4" screws no pre drilling just go straight in.

I'm guessing you mean at an angle Gregers, like skew nailing? As a four inch screw wouldn't reach through the total depth.

I've got six windows to do at different times so hiring wouldn't be that cost effective. Would the 'manual' version be to drill and screw at an angle?

Thanks for your help.

mmmm,ok could you not use something like a paslode then??

Same problem really, it's a one off on my own place, so hire/purchase cost is disproportionate to the requirement.

I'm assuming that the powered options you mentioned make the operation easier given the slightly awkward nature of trying to fix a relatively deep section onto a narrow face.

Is it mainly a time saving thing when compared to doing it manually or is it just a bit of a ham fisted way of going about it? I have time on my side, just didn't want to make a pigs ear of the fixing!

So given my tool limitations, is screwing at an angle the best way to fix?

Cheers.
