I have a colonial built in 1913 and iI live in NYS. My roof was just completed today and I have exposed nails across the entire roof and it!
It was not like this before. When iI asked the contractor about it, he said this is normal. But im, but I'm having a difficult time accepting this answer. I have included a picture to show what the entire roof looks like from the inside of the attic. I appreciate your feedback. Thanks.
