flat roof edge detailing

[bluebaron]

anyone any idea how to finish the detailing on this flat roof?

I won't have an 'upstand' on the edge or the roof as plan on using these EPDM trims:

as such shall I just leave it at that or will it look a bit odd? Don't really have any fixings for a fascia board.

Roofs should overhang walls unless you want the wall to be soaked every time it rains

He is using edge trim which provides upstand.But not clear if he understands this is attached to overhanging facia boards.

Yes exactly. Usually I would fascia then trim but as from my (badly drawn) diagram you can see that the Joists run parallel to the wall and the top of the joist is level with the wall hence when I add 18mm OSB I will run it over the joist/wall to the edge. how would I fix the fascia? unless I glue it to the wall?

I've seen plenty of flat roof garage's with no overhang its pretty standard I believe.

Makes no difference, and it's nothing to with roof run off . All walls should have a roof overhang, be it a verge a soffit, a parapet, whatever other wise the wall gets wet at the top.

LOL.

Yeah I see litter everywhere, bad driving and men wearing black belts with brown shoes and it does not mean its right.

I can’t add an overhang on the other side as it’s up against a road and trucks will hit it.

This photo looks like the existing roof has a fascia board? Why can you not construct it in the same manner?

 

[bluebaron]

Yep I guess I won’t tell until I start stripping it back I think that’s attached to the wooden upstand that won’t be replaced with as I’m using a Modern EPDM roof as edge trim.

I took a photo looks like what I said above,

Which he has.

Oh yes, silly me, my mistake

You are forgiven.

So the question remains, is a fascia board required and if so how to fix it?
