We have a small building with a rubber roof that was installed maybe 15-16
years ago. Visibly it looks good and I can even plainly see an "Armstrong"
logo on the material.
This past fall it started leaking ..but it's leaking in a few places
something that looks like motor oil! ..and quite a bit of it at that. There
is an adjoining, but higher, roof that last year was coated with asphalt
fiber based material. However there is no evidence I can see that this is
the cause and the roofs are separated with a step-down wall with its own
aluminum cap. No evidence of anything running down the wall. (And if the
lower roof didn't leak water, why would it leak anything else that might be
getting on it from an adjoining roof).
Any clue on what this might be?
I know it sounds weird, but the liquid was the viscosity of something
between water and used motor oil ..and probably about the color you would
expect from such a mixture. I wondered if maybe the rubber roof was put down
with some kind of petroleum-based adhesive that was breaking down. When I
looked across the puddle on the floor, it even had the rainbow effect like
an oil and water mixture. And I had to soak it up using oil absorbent (it
generally would not evaporate, but where it did there was even like a black
bakelite/charred type of residue).

There will be some oils from a newly applied roof that water will pick up.
It could be enough to cause the sheen, but I can think of anything that
would cause a viscosity change. Still, if this fluid only appears around
outside precipitation, I'd say common leak. If not, I have no idea.
==================================Not the rubber, nor the rubber cement they used .. if it was correctly
with authorized materials. It is possible that the rubber was placed over
existing asphalt surface? What you are describing fits perfectly with
a piece of ordinary asphalt shingle sitting in mildly acidic water, such as
