Is the chimney flashing completed correctly?


I just had a new roof installed. Was the chimney flashing installed correctly?


I’ve seen worse. Does it leak?


I really don’t like the fasteners through the counter into the roof. Lot of guys here do it though I’m not sure what the perceived benefit is.
If it doesn’t leak I wouldn’t mess with it


Need closer pictures I can’t see if the counter flashing is inserted into a raggle, by the way it is angled at the vertices tells me it’s not likely.
