I was thinking the same thing, but here’s my guess:
-Cold, foggy night/morning = frost forming
-Cloudy until early-morning so the sun doesn’t warm the shingles
-Clouds clear up a bit by mid-morning, and the sun rapidly warms up the shingles, leading to the frost evaporating quickly relative to the shadow’s motion
This can’t be a coincidence. Something has to be going on. Do you have a refrigerator in your attic that is that exact shape?
Is there even a shadow of a doubt?
Ooookay, got a chuckle out of me man, thanks.

Maybe his neighbor is a climate controlling liberal?
