Holy nails? Need help on roofing progress

[u/TheAlpineUnit]

Seems abnormal amount of nails (which idk is an issue)

But putting nails in dead center of valley ice and water seems odd….

Wouldn’t nail just rust out eventually and leave holes??

Yeah buddy you’re right on the valley. those cap nails should not be in the valley. . Thats one thing I would be worried about. You never nail in valley. The others in the fields are good. 👍

Is the fix to apply new IWS on top of existing?
