Hi first post on here so please go easy on me !! :cool:

I'm proposing to add a single storey extension to my house.
I want to add a lean to roof with vaulted ceiling with Velux rooflights.
The extension will be approx 6m wide x 4m out and want the whole 6m width to be glazed.
Will I need anything out of the ordinary structurally with a 4m lean to span onto the glazing ?
Also would I need to ventilate the roof space as I'm a bit puzzled on this part with wanting to vault the ceiling ?


Thanks in advance.

I think your idea is bonkers.

Why do you want roof-lights in a glass roof?

The heat loss issues alone will be prohibitive let alone the design for the rafters/glazed roof.

I think he means to do the rear wall in glazing not the roof.

To the OP you'll need a steel beam to span that opening something like a 305 or 254 deep UB. No need to vent the roof if its a warm roof.

No roof will be tiled not glazed.
Do you really think I would want rooflights in a glazed roof.

Did this not give it away slightly ?

Thanks for the replies, appreciated. :D

Can anyone advise the best way to achieve building regs with vaulting the ceiling with a lean to roof in respect of insulation ??
