While reroofing and venting this home, our crew pulled off the flashing cover and heard a loud crash.  When they looked into the hole now in the roof where the flashing was..they saw this cast iron flashing piece inside of the home. 


Homeowners should check to see that the plumbing flashing pipe isn't rusted through to the point it will fall and then serve no purpose.  This piece had its threading still in tact, but just as they removed the cover, it weight was no longer able to be supported and fell from the roof.
