Soffit Overhang

[Onoff]

What's the ideal overhang distance for a soffit like this? Shallow, tiled roof above. Thinking to redo in uPVC. If it's say 300mm I'll trim all the roof joist ends down. They're a bit in and out anyway.

200mm is fine - can go to 150mm if you want to. Just may end up with a shorter fascia. 

[tonyshouse]

Taller fascia if cutting back the existing and keeping the soffit in the same place. 

[Gone West]

Our standard soffits are 250mm. I like the look of deep soffits and at the back of the house they're 750mm to tie in with the balcony.

[joe90]

I too like deep soffits, mine are 400mm ? (and have false rafters to make it look “cottagey “).

[Pocster]

Based on the title ; I suffer that occasionally

Am I missing something 

if you reduce the soffit size, will you not have to change the roof above ??

Not if you instal a bigger facia board ?

Have you been on the sherry @joe90

 

if you reduce the soffit size then surely the length of the roof from ridge to facia will decrease, so the facia gets taller, but the roof gets shorter. 

 

But knowing @Onoff maybe he’s thinking of installing a flux capacitor in the void or something.

Tbh the tile projection over the gutter varies a bit and could do with equalling up along its length. I'll fire the laser along to get a line and see what the minimum is. Might aim for a 300mm wide soffit as that's off the shelf.

tiles yes but roof structure no. (I don’t like Sherry ?).

is the size of the soffit reflected on the rafter timber size and if you have a room in roof?

Not really.

[Vijay]

I'd have thought a larger soffit increase the room size though?

Building a loft room and roof maybe but this structure already exists.

I've got 300mm stated on my drawings from architect. Also he's got a note saying boot ends are not allowed.

What's a boot end?

This. 

[SuperJohnG]

My architect likes this...apparently a nicer detail. 

 

I've yet to figure out how I get lights in the soffit. 

[Alexphd1]

Are you redoing the roof? What look/style do you want to achieve? I don't think there is a ideal soffit size, but more down to personal taste. For me I like big soffits and flat on the horizontal run but I also hate boot ends (never heard them called that before). My architect originally drew no soffits and skews which protrude above the slate at the gables, these got changed to make build simpler.

No. All the soffits and fascias need redoing. Rotting in parts tbh. Been putting it off as I want to change the roof but that isn't going to happen anytime soon so I'd best get on it in good old basic, (cheap), white uPVC. Working backwards tbh, all the felt edges are shot and need eaves protectors adding at least.

I have done a Lot of those in the past, rip off facia, soffit etc and a few rows of tiles and battens, straighten the joist ends a little, tuck in eave protectors, new facia and soffit, replace battens, tiles and guttering, simples ?.
