What are these things poking out the flat roof?

Spotted them when looking at a fascia job the other day.

Flying leap of a guess is that they are for harness clips to run along. To keep people from falling off the roof?
Never seen them quite like that though...

Yes, they're a fall arrest system.

good call. spot on. there are photos if google roof harness arrestor posts.
the ones in mwrooflines photos are retrofits and they are allowing water into the flat roof. expansion bubbles can be seen.bad roof.
the vent pipe is different to ones ive seen?

the cove above the fascia looks like a wood gutter with lead lining.looks like its failing.
theres also a maybe problem where the parapet cover meets the fascia. just thought i'd mention what you probly now.

Submarine? Is it in Portsmouth?

Anyway, if you are quoting for that job and working off that roof, then you will need to be trained in the use of fall arrest and roof access systems and have your own suitable PPE to connect to it.

Thanks for the replies. It’s a small double storey flat roof. We’re not working on or near it, it was behind what I was looking at. We don’t do flat roofs or work off flat roofs, we just do fascias and cladding off scaffold so I hadn’t a clue what they were. I thought they were gas canisters
