Flat Roof - Fascia and soffit installation

[Stuckster]

Hi all,

IMG20250218121703-EDIT.jpg

Working on a flat roof extension for a large under cover deck (not enclosed).

What would you call this end beam?
Its a 200x63 LVL tying all of the rafters together.

Secondly, how would you go about installing a metal fascia and ceiling cladding/soffit in this situation?

Standard fascia clips won't work since the rafter ends are not exposed.

So... maybe screw a timber fascia board over the top then proceed as normal, or attach a metal fascia cover and guttering directly onto the beam? What would the soffit hook into?

Appreciate any ideas/insights.
cheers

I believe it would be classed as a veranda beam.
If you are wanting to cover it with a metal fascia you may need to install blocking to mount the brackets.
Can you not use the beam as the fascia ?

Yes it could be used as the fascia. But I'd like to protect it with a metal fascia to match the rest of the house and to save painting it every 2 years!However standard fascia covers are only designed to fit 25-30mm fascia board, not 63mm beams! Perhaps custom flashing may be the only option?

By the photo, it looks like the fall is away from the beam. If so, I would ask (and have in the the past) my roofer to have Lysaght form a steel fascia that caps the roofing ends, covers the front of the beam and bends under the bottom of the rafters to take ceiling cladding.

If the fall is away from the beam, I'll post a drawing if required

If you used a metal fascia cover over the bottom face of the beam that would leave about 35mm uncovered at the top, your gutter would cover that gap.You could even have a flashing to cover that top section if you were worried about weather damage, the gutter would cover the join.https://www.mrbsupplies.com/flashing...cia-coverThere would be 28mm of the underside of the beam exposed where the soffit could be attached, or put it on before the fascia cover.

Actually, regardless of the direction of fall, you can have a steel fascia folded to anything you'd like to specify in this situation

No, just a deceptive angle. The roof will pitch towards the beam about 2 degrees.

I presume you mean something a little like this?

Good thoughts.
So it looks like either a custom flashing or a combination of a standard fascia cover and additional flashing to cover the top.

Thanks both for your input.

What are your thoughts on ceiling battens to attach the ceiling cladding and soffit?

They're not required by code (if your framing meets certain tolerance, which ours does), but do you have strong opinions either way?

The rafters are set at 450 centres and are LVLs. So they are already well spaced and level. The roof will have anticon blanket and ceiling batts, so moisture and condensation should be very minimal.

Battens would provide an air gap under the bottom side of the rafters, but other than that are they overkill for the extra time and money?

The fascia would obviously have to accomodate the additional height of battens if installed.
