Gracesickles?

I've been running into this quite a lot here in nassau. I suspected it was grace but most of it has been coming from under metal roofs so I couldn't check to see. This is the first I've seen it under fiberglass/asphalt shingles which I was able to lift and see for sure. I know people are gonna blame it on the heat but I've seen it coming from under white metal which remains cool no matter what. Anyone else seen this before?

Wywoody being exposed has nothing to do with it. I've seen it bleed out from under shingles on steep roofs. My first thought was Ole Jack had installed the skylight but when we pulled it apart it was in fact grace bleeding

ARRRRRRRRRRR..AHOY THER..WELL SHIVER ME TIMBERLINES...LOOKS LIKES OLE JACKS CALLIN CARD FOR SUUUUUURE....ARRRRR..A MITE PERTY..AINT IT??

Not to surprised, even though it is a miracle cure for crap installations.

Yes I see it all the time on steep roofs were it was used around chimneys and skylights
