On an ancient roof we’ve been band-aiding for what feels like a decade, and may actually be;
These postules are popping up EVERYWHERE:
Something is sucking the EPDM to the insulation. It’s a layer of wood fiber, and they have slowly grown, and spread across the roof. The makeup has fiberglass insulation below the wood fiber, and steel deck.
The rate this stuff has spread, and grown, it can only be some sort of weird fungus attacking the EPDM, as it’s almost suctioned down in these sections only, and has spread and grown over the last decade or so.
This is certainly bizarre, and something I have never seen before. The EPDM is almost 38 years old, and make in Indiana at the time.
Anyone know what the heck this is? Me Either.
Only in roofing.
