Soffits and Fascias replacing advice
James - 31/7/14 at 09:14 PM

Greetings all!

The fascias are rotten and the guttering has dropped off round most of the house! It's been empty for 4 years so fairly unkempt! (those fascia tiles are sorted btw!)

I want PVCu and there's a supplier nearby.

It's a job I'm thinking of doing myself with scaffolding as there's fairly good access all around.

However, I've had slightly conflicting advice as to what to use.

Obviously I'll be ripping all the old fascia (and soffit) off but am I meant to then fit 18mm PVC instead, or is it meant to be treated timber first followed by the 18mm PVC?

Or something else?

Any other hints or tips?

Thanks!
James

Just to add,

we live on a fairly busy road also, if it affects the ventilation at all, we might have a loft conversion at some point.

The fascia is fixed directly to the end of the rafters, wood or pvcu. Maybe your getting confused with a cladding or capping fascia that is thinner (approx 8mm) and is fixed to the old existing wooden fascia to cover it up. If you're removing the old fascia you want 18mm thick.

There are essentially 2 types of soffits You want the "full replacement" type which is more rigid and designed to support guttering ect. The cover up type is only about 9 mm thick and very soft/ weak which needs to be fitted to already sound wooden soffits.

Okay, so 18mm "full replacement" is good enough on its own then? Without timber beneath. With guttering hanging off it?
Is there any benefit to fitting new timber and then covering it with 9mm over the proper 18mm?

What are the opinions of those plastic trays that go under the final sheet of felt and sit in the gutter (I forget the name)? Beneficial? Added complication?

EDIT:
Also, should I be fitting those round vents (or any other type)? If the house (1960's) wasn't 'designed' for that level of ventilation, is there any benefit?

Thanks!

There's no benefit with wood and thin soffit. It just creates twice as much work. Most new build low maintenance houses use the 18mm. I did with my garage. I screwed through into the ends of roof trusses to support gutter but was told by supplier the facia will support it no probs just make sure you use chip board screws as they grab better.
The plastic tray is to repair the edge of old bituminous felt that has rotted away due to sun exposure so with it being and old house then it would be good to fit it.
Vents are a good idea to keep fresh air circulating and prevent damp/ rot

Can't you just cover the old wood or is it mega rotten.

I didn't use scaffolding u just used 2 people and 2 ladders.

5 lads are out doing mine right now, looks like they've taken the old wood fascias down with guttering still attached, and putting up 18mm PVC fascia and soffit (with vents all along) straight on. though i've not really been watching, just seeing whats come off, and what had been delivered
