Fascia board kick up height

Evening everyone hope all is well.

I'm doing a 40 degree gable roof tomorrow using 4x2 , it's only a small roof.

I'm using plain tiles and a 200mm fascia board.

I'm presuming I need to cut the soffit of the rafter to allow the fascia to lift up to allow kick up for the eaves course.

Question is, is there a standard height to do this, I don't want to kick the tile up to high.

Same goes for Redland 49s aswell.

Thank you all

Do one and half inch, the tiler will add a lathe if necessary
There is a formula a carpenter once told me (type of tile/slate + pitch =) but im not a carpenter
Rule of thumb is if using inch batten inch kick off fascia. Lower pitches (below 30 inch and a half) .

Don't forget to factor in (if applicable) over-fascia vents. You may need to reduce the fascia depth by say 25mm in order to accommodate this type of vent.

As for fascia kick - 40mm minimum. Sometimes it is more.
With that angle and fascia, you'll likely need kickers on each rafter.

And as you have preselected the fascia depth rather than chose it to match the design and kick the tile up, a lath would be better to kick the tile up instead of relying on the fascia.

Don't forget the felt support tray.
Thanks for all your comments! Really helpful and made sence.

I've got another cheeky question if ya wouldn't mind, no point starting another thread because I know someone here knows the answer :)

I've been looking at this box end this fella has done off google and trying to figure out what he measured up for the first small undercloak and how he acheievd that first little angle, I guess once this is sorted I'll know what angle to cut my timber kicker/wedge

Cheers lads,

P.s I'm using a 200mm soffit and taking it 100mm around the wall and fixing it behind the wall plate
