Deeper kerb trim

[idris]

SIPs flat roof, to be topped with EPDM. 

3x kerb edges, 1x drip edge / gutter.

 

Pretty much all the UPVC kerb trims I can find have a vertical height of around 90mm, including the up-stand.

I can't find anything deeper. Ideally I'm looking for something around 150mm.

Am I spitting in the wind, and do I need to look at a different way of edging the roof?

Not a SIP roof, but I used UPVC fascia board on my garden room, with the EPDM kerb trims added on top
