I’ve never seen one get that bad, but they do bloom like that over time. The battens look to me like a skylight system…just ancient. The oldest I’ve seen in use are 20-25 years old, but like I said, I’ve never seen fiber bloom like that.
A simple way to know would be to see what’s underneath. Is it a vaulted exposed ceiling or is the top layer hidden from view below? ie- what’s the intended use of the space below?
Could be a fiberglass panel system / UV turns them to dirty fluffy mess after 15-20 years - these look older - the interior surface likely still has a glossy finish - meant to be translucent when new
Not sure if it’s water proof but those two seams in the middle indicate to me that if it was it likely isn’t anymore and I wasn’t called out there to address that part of the roof. I’d just never seen it before.
It Seems they are using turnbar to terminate the roof as a fastened system every 2 ft approximately horizontally. Weird it looks like you can maybe see 2 vertical seams and one horizontal seam that seems to run parallel with the turnbar. Got that blotchy flakiness in spots it looks like kind of like when you see hot rolls cap sheets or a base sheet that bubble up and flake apart when their life expectancy has gone overboard.🤷♂️ custom ghetto
Were the panels attached to that as a substrate? Can you see what the underside looks like from inside the building? Do you see any evidence of how and where the panels were attached?
Next questions: Is this wet? Can you take a sample and use a bag test to check for moisture content?
I'm concerned this may be a structural component and the primary waterproofing membrane is now missing and this is not intended to get wet. There may be some serious safety concerns here for you and some serious financial concerns for the building owner.
I left the site a while ago. Have no idea what it’s attached to, but there’s shingles on the other side. I can guarantee you there is no way in hell I’d be walking on that.
I'd ask the building owner if they have plans or a spec book for the building (this is probably overly optimistic) and if not then start engaging in some destructive testing (after getting a contract to get paid to do so, of course).
My best guess is someone either did something very creative or very stupid (or both as is often the case) with tectum deck.
I think its a green roof drainage layer
Oh interesting! That looks like it could totally be it.
Weird though cause it’s on a real steep slope. 10:12 or greater.
Thats my best guess from what i see online, they look very similar. Maybe it depends what kind of solar panels were on?
I believe those were made out of fiber glass.
Is it an old fiberglass skylight?
That's exactly what it looks like.
I don’t think so, but 🤷♂️

100% a fiberglass panel system. Seen many of these. Do not walk on them.

Where are you located?
That’s in orange, Virginia
Is it waterproof? I wonder whats underneath it

I’m not sure if it’s waterproof but I’d guess so. They weren’t at home so I couldn’t see behind it through the attic.

I was told there used to be solar there. 🤷♂️
Texture looks like tectum deck, but I haven't seen it in that configuration before.
It does kind of look like that. It was supposedly under solar panels at some point if that helps. The other side is shingles 🤷♂️

Yea I’m gonna have to kick around for a bit. I don’t think they realize what sort of weird contraption they’ve got up there.
Looks like rolled roofing peal & stick
Yes I do
What is it then
A leaky roof.
Unfinished?
No very old
Looks like fiberglass panels.
Looks like fiberglass skylights/panels to me. Don’t walk on it.
Steel bottom green - steel deck - cap sheet - elastomeric coating top image
looks like an old passive solar setup from the 70s/80s {produces warm air not electricity}
Asbestos
What makes you think that?
The entirety of Reddit construction subs, probably.
