I'd like to extend my flat with a new single storey extension.
A section of the roof is a shared party structure with the upstairs flat / neighbour (who are tenants).
The neighbours will want to use part of the roof as a walk on terrace with tables and chairs, plants etc, which is fine.
I just need to design it in with a structural engineer to take the load, and choose the most hard wearing low maintenance finish to the roof, that is tenant proof!
So options I'm considering on a concrete deck as a base with insulation on top are:
1) GRP walk on grippy membrane
2) Paving on small pedestals
3) bitumen / polyurethane type single ply membrane (hot applied)
4) cold liquid applied membrane
If the roof terrace belonged solely to me, I would do paving slabs on pedestals, as it's the nicest looking solution.
However, as the roof terrace will be used by the neighbours, who do not have a good track record with maintenance - what is the best solution?
Thanks!
