Fascia & Soffit work

[Notadecor8ter]

Hi,

I have just started a project to cap over existing on my property.

I've ordered capping fascia and normal soffit so far.

I've begun doing some learning on the garage thats attached and accessible so I've done a gable side of my garage and now doing the back of the garage but it appears the non gable section of current fascia is grooved and they originally have run Ply soffit through the groove and attached to the brick wall.



At the moment I've got U Trim in line with the bottom of the fascia so 20mm below, this seemed ok but im concerned about how long it will last with the weight of a normal soffit.

Looking at the tongue groove approach and this being easier to work at height as well I've ordered hollow Soffit for this but is there any better/cheaper/easier option to complete the eventual over four sides of my house getting this one or is a trim the only option attached to the wall below joist line?

What do you mean by normal sofit and how were you planning on ventilating it. You can see several ways of doing it here. https://www.google.com/search?sca_e...EAHUCKJwMQtKgLegQIEBAB&biw=1470&bih=807&dpr=2

I was going with Circular vents cut out.

Still not sure I want to do the soffits this way on the roof of my house, drilling in it a pain in the arse and I'll need to do an awful lot of it for the four sides of the property.

Should I just put screwed battens down between existing batten on the wall side and the existing soffit ?

Just install soffit vent strips or use pre vented soffit boards?

If you're fitting it over existing (solid non vented) soffit and you don't want to remove this, could you use a cordless mini router to essentially create a gap/vent in the existing soffit, then cover with new vented soffit?

Sorry I apologise, I've not given the whole story as I'm rushing around.

I originally ordered normal soffit but have now gone with Hollow to tounge and groove it.

Reason being it's lighter and I wasn't sure normal soffit would sit in the trim weight wise.

So I'll be using hollow soffit with round vents, it's a case of how I get it aligned with the bottom of the fascia.

Green is Fascia
Purple would be a wood batten
Yellow the trim to put soffit in
Red hollow soffit

If you're doing any drilling/screwing into the existing soffit, ensure it's not asbestos soffit first.

Why don't you cut the soffit so it fits between the brickwork and the inside of th fascia, the bullnose on the fascia will hold the front up then screw along the back and use white screw caps which according to your diagram you'd have had to do anyway?

 

[Notadecor8ter]

Yes, it's possible to do that but it slants at the difference in the batten and bottom of existing fascia. It looked a bit heath Robinson when I've done the back of the garage.

Not too bothered about two storeys up though.

Where would the slant be if the new soffit is tight up under the existing? Don't use the purple batten
