Roof Insulation of 1960s Block

[ColdUpHere]

The roof insulation of a block, which still has its original flat roof, is minimal. The lower flats are unaffected because they are insulated from above. The owners of the top flat are the only ones that are affected.

The addition of exterior roof insulation would be expensive and surely get voted down at an AGM.

But, if and when a new roof is required, is there legislation that will require a new flat roof to have exterior insulation that meets current standards?

The block is leasehold with ‘right to manage’ by its owner occupiers

Thanks in advance for comments.

Yes. Part L building Regulations.

Commercial re-roofs are handled by roofing contractors that use shaped insulation with falls included. Obviously any objects exiting the roof are taken into account, during the survey process.
