Flat Roof - Fascia and soffit installation

[Stuckster]

Hi all,

Working on a flat roof extension for a large undercover 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/ceiling cladding sit on where it meets the fascia?

Appreciate any ideas/insights.
cheers

Hello @Stuckster 

The beam at the end that ties all the rafters together is commonly referred to as a "fascia beam," "end beam," or "ledger beam" in this context. Given that it is an LVL (Laminated Veneer Lumber) beam, it is structurally designed to provide support for the rafter ends while also potentially carrying the weight of the guttering system and soffit.

Fascia & Gutter Installation Options

Since the rafter ends are not exposed, standard metal fascia clips won't work. Here are two possible solutions:

Timber Fascia Board Approach (More Traditional)

• Screw a timber fascia board onto the face of the LVL beam.
   
• Attach the metal fascia to the timber fascia board using standard fascia brackets.
   
• This provides a more standard setup for installing gutters and also gives a neat finish.
   
• The soffit/ceiling cladding can then be fixed to battens installed underneath the rafters, meeting the back of the fascia board.
   

Direct Metal Fascia & Guttering (More Modern)

• Instead of a timber fascia, you can fix a metal fascia cover (such as COLORBOND fascia covers) directly to the LVL beam using appropriate fasteners.
   
• The gutter can be secured directly to the fascia cover using concealed gutter brackets.
   
• For the soffit, install a timber batten or metal top hat section underneath the rafters, right behind the fascia, to provide a fixing point for the ceiling cladding.
   

Soffit/Ceiling Cladding Fixing
 

• To support the soffit (e.g., VJ boards, FC sheeting, or aluminium battens), you’ll need support battens running perpendicular to the rafters.
   
• The battens can be timber (e.g., 70x35mm pine) or metal top hats, spaced as needed to support the cladding.
   
• Where the soffit meets the fascia, you can either:
  
  Fix it directly to the back of the fascia board if using timber.
  
  Use a small L-angle or timber trim to create a neat transition.
   
• Key Considerations
  
  Ensure the gutter has the correct fall for drainage.
  
  If using a metal fascia cover, check compatibility with your chosen gutter system.
  
  Plan for ventilation under the roof, depending on local building codes.

Hi @Stuckster 

I don't think I can add any more information than the great advice already provided by @EricL, other than your cheapest and easiest facia material will be timber. I love the finish of a metal facia, but it is very difficult to install as it can bend or twist in the process as it can kink fairly easily ruining the finish.

Morning @Stuckster 

I am with the same opinion as @Nailbag , If I had to choose one to recommend I like the idea of the added timber facia board to make it easier overall that @EricL has suggested as the one id choose, but all of them work  

With the timber battens to support the underside of the facia (soffit) I had to look up the meaning of the name I also agree with that as the way it should be done.
