Hi,
For an outbuilding, we have 9inch (220mm) roof joists and 4in (100mm) insulation and 18mm OSB3 boards for a warm flat roof.
Based on this I think I will need at least 340mm Fascia boards - but I can't seem to find any; most seem to go up to 225mm only..
I was planning on using 18m fascia boards which i could nail directly onto the joists, rather than put timber board on top.
Will be putting on an EPDM roof membrane on top if that makes any difference.
But am a bit stuck as the 225mm facia boards are too small and i can't find the right size ones..
Any suggestions on what I can do to fix this?
