Del-inquent Posted October 24 Share Posted October 24 We are having all the soffits on our Chalet Bungalow taken out shortly as they're asbestos cement and the window installers want it gone first. I'm just not sure about how to replace them, never done any on a roof structure like this before. There is nothing at all supporting the soffits at the moment, they're just sat upon the external leaf and held in place by a groove on the back of the fascia panel, nothing to attach any replacement to at all. The facia's may well be replaced as well, will have a look at the condition of them once the soffits are down as they're currently capped with UPVC (badly). Soffits are 380mm from wall to fascia. I wanted to replace them with UPVC, cheap and cheerful and as little fuss as possible and if the fascia's do need replacing (pretty likely) I'll use 18mm UPVC ones. How would you approach it?

saveasteading Posted October 24 Share Posted October 24 Fix a triangular batten under the rafter against the fascia, and screw up into it? 1 Link to comment Share on other sites More sharing options...

Would you bother with any additional support for the soffit - like ply run underneath the batten before the soffit goes on, or just straight up with some soffit?

saveasteading Posted October 24 Share Posted October 24 Depends on the soffit. Is it stiff and can pan that distance? You will have to fix it at the wall side too. A batten on the wall. Link to comment Share on other sites More sharing options...

I guess as it'll be sitting on top of the wall and pinned every 400mm (or thereabouts) plus supported by the fascia, probably should be okay. Can't put a batten on the wall as the wall stops just below soffit height lol Link to comment Share on other sites More sharing options...

Apparently our uPVC soffits replaced asbestos ones as well. 1 Link to comment Share on other sites More sharing options...

The wind has never moved it. I've not tried hosing it because I didn't want water going in the vent slots. I have brushed it with a broom and it was ok. To a degree it is held in place by the slot in the fascia. I won't be altering it for the time being. Link to comment Share on other sites More sharing options...

Interesting, I’d never have thought that would be sufficient on the width but I do have a habit of over-engineering everything. Link to comment Share on other sites More sharing options...

Run the horizontal batten the full way around the house, not just little bits, you can add a batten front to back as well. 1 Link to comment Share on other sites More sharing options...

Why are you removing them? The best practice for asbestos is to leave it be. Will the window installers work involve them cutting/drilling in to the soffits?

They’re in a bad way as is the facia on one end, so work is needed regardless, plus the soffit sit on top of the window frames and have been sealed to it in the past. Ideally I wouldn’t have touched it but it has to be done Link to comment Share on other sites More sharing options...
TommoUK Posted October 27 Share Posted October 27 If it's AIB (asbestos insulation board) its nasty stuff and notifiable work. Get someone licenced to remove it and ask them for a post completion report so you can show what has been done should you sell. Link to comment Share on other sites More sharing options...

Had it tested a couple of weeks back, it’s not AIB just asbestos cement board, non licensed, however I am still getting someone in to do it as I don’t want to. Some things are best left to the pros. 2 Link to comment Share on other sites More sharing options...
scottishjohn Posted October 28 Share Posted October 28 when you expose the rafters i would look carefully that they are not rotted at the 4 corners of the roof where the barge boards affix i had to cut them out and graft in bits when i was replacing my plywood soffits . iwas lucky in some ways as the actual soffits were T+g boards ,so icould nail everything to the plywood and old soffit boards very common when only single battons are used as they collect crap behind them and make sonewhere for water to sit single battons to me should never be used as there is no direct path vor water to exit ,just makes dams especially as htis is anold roof using roofing felt ,it gets hard and can disintergrate where its not supported 1 Link to comment Share on other sites More sharing options...
