Can I use sloping roof void?

DavidJonas

We have a sloping roof over the porch. It is tiled up to the second floor which is set back a little bit.

We are having an extension built and where the guys have ripped away the side of this (the slope will carry across the front of the new room), it has revealed what is inside. Which of course is basically nothing. Looks like a big bit of chipboard and then a big void between that and the wood supporting the tiles.

Would it be easy to open this up? Would it be wise?

This would in theory give the porch considerably more height as the roof would slope up. It would be add much more space to this bit of the house. Not functional, but you know, nice.

Could it carry across into the new room?

Is this sort of thing easy/cheap to do? I would like to know if possible before asking the builders !

Although the kitchen is not being touched, part of me now wonders whether that (currently a flat roof) could potentially be sloped up to the second storey with Velux windows. Would certainly get more light into a north facing room. A job for the future perhaps.

You've not explained your layout very well. I can't provide any specific advice.

But of course it's possible to vault a ceiling, it depends on how the roof is constructed. Ceiling joists more often than not form part of the roof structure so it may not be easy to convert an existing one.

Insulation is also a concern. It all needs to be planned before being built. If you want a vaulted ceiling, it has to be planned and costed before being built. It will cost more than one with a level ceiling as solid insulation is expensive, as a start.

Thanks. Yes, it probably is a bit late in the day !

Think I will rein in my ambitions.
