This is a flat roof of a house extension ~ 23sqm

Roofer is quoting to re-felt (boards are ok) but I'm wondering about
these newer materials such as the Firestone Rubber Roofing Membrane or
others.

Any views?

As a person who walked about a lot on flat roofs until last year, I was
always most impressed by the glass fibre ones, and least impressed by
the membrane ones (which puncture easily).

Come across many metal ones (ali rather than lead)?

I daresay the fibreglass are better, but presumably more expensive too?

If you will wear hobnail boots and rest aluminium ladders on them ...

Well no. In all seriousness, I worked on a large development that had
these roofs and they were a real problem to everyone. They made access
to the walls above the flat roofs very difficult.
On older buildings damage is inevitable if roof access is possible.
Tenants will go up there to get balls back or send their aerial
contractors, etc.

I always make a point of wearing plimsolls when going up on mine, and
brushing any stones out of the treads, and have a chunk of 3/4" ply for
a ladder base - I'd want to keep an eye on anyone going up on it ...

Yes it's OK when there's a knowledgeable and watchful owner, but not
really on a block of council flats occupied by council tenants, some of
whom might not have a respectful attitude to the building.

Actually, there's a worse idea. We worked on a major refurb project
which involved removing the top floor and putting a new roof over the
rest. It was decided to install a proprietory roof system that consisted
of large plastic panels which simulated a tiled roof. Afterwards, when
the tenants started to walk about on the roofs (access being a simple
matter of striding over a low wall from the patios of the next row up
the hill) the panels started to dint and bend, and now, 15 years later,
they look shocking.

For a flat garage roof 5m * 5m I receive the following quote

Total£2000+vat
Or
Same as obove laying 1 layer felt .
2nd layer high tensile blue grey 10 year guarantee

--------------------
my preference is for the Epdm. The alternative would be to install a
pitched roof as a DIY project.

I cannot remember exactly what my flat roof was, but your quote sounds
in the right ballpark.
