Flat Roof - Metal Overhang

[tvrulesme]

I'm in the process of building an extension with a flat roof. Looking to recreate a metal fascia/soffit like the picture below. My google searches have been a little unsuccessful. Most of the fascia's I find are designed for pictched roofs. Would I be looking for off-the shelf fascia/soffits or are these usually something you get fabricated? What should I be searching for? Fascia, soffit, overhang, coping or something else?

 

I'm still in the design phase so would be easy for me to adjust the depths etc of the timber the metal face will be attached to if that saves money on bespoke.

I got a local metal fabricator to make some for me for my garage roof.

 

I screwed up though as we have an EPDM roof which is finished off with a PVC trim piece. I should have had the metal fascia the full height of the roof fascia with the PVC trim over the top of the metal but I stopped the metal short, pretty much level with the base of the PVC trim and it looks a bit rough. 
 

I’ll draw a picture to clarify the above if you’d like.

Thanks a lot @Russdl Still looks very tidy from the pictures but I get what you mean. I'd like to get metal capping to match ideally. 

How did they fabricate the joints? Is it just a overlapping piece or did they do something special?

[Russdl]

The corner pieces overlap the straight fascia bits.

 

One of the reasons I had them locally fabricated is that the corner in the picture below is not a standard 90 degree corner but 75 degrees.

 

I designed mine to be fixed through the soffit element (which would be hidden by the EWI) and the top of the fascia element (that would be hidden by the PVC). The hidden fixing bit worked, I’m just disappointed in the finished look - however you don’t really see it unless it’s pointed out so I should get over it eventually!

Very good point. I have a lot of non-standard angles and some weird gradients to deal with. Will have a chat with some local fabricators.

Look up, GUTTERCREST, they fabricate this sort of stuff. 
if you go for aluminium it will look the best, but cost the most. 
zinc coated steel is available, but will have a bit of a wave effect as it’s relatively thin. 
there’s a company in the midlands who also fabricate these in aluminium, I’ve had all my window cills from them, very nice stuff, but I cannot remember the name, something like ARCHITAL.

We're at an early stage of sourcing similar. I was also going to mention Guttercrest. Alumasc Skyline look like a more 'off the shelf' option

If your in the west mids, go and see mark at archital or something like that, I’ve had a couple of grands worth from him, spot on service.

I bought aluminium copings for my parapet because I like the look but  mainly because I have spent many weeks over the years removing and replacing parapet masonry. 
 

I was adamant that I wanted the clean lines of aluminium and when our GRP roofer said he could replicate this using GRP and at a cost saving I was still sceptical and stuck to my guns. Since then I have seen some of his parapet work and I’m very impressed. Next time I will take this route.

It's a listed building and unfortunately the conservation officer requested metal. They don't like fake and they don't like cost saving 😪

The Alumasc stuff looks nice but it is very expensive. I have two 3500mm x 400mm parapet walls to cap and I'm looking at over a grand in Alumasc which seems very punchy. I'm in Kent too and looking for a recommendation for a local fabricator. I had fascia made, but the end caps probably need to be fabricated to get a good finish

I'll keep you posted as I start talking to them. There seem to be a few from the large ones like Rhino

Down to small outfits like this guy who has great reviews

Thanks for the tip.  I will hopefully remember this when I eventually get onto my roof. I expect the GRP solution means there are no visible joints, which would be a big bonus.

I'm not a fan of GRP. My main gripe is photostability. In my (limited) experience GRP tends towards brittleness as it ages.
