I have just had my roof done by a great crew of guys who worked very fast in super cold weather (15 F) but they seemed really skilled and competent. Roof looks great!
Then a week later I am up on the roof to clear snow off some skylights and I see a row of exposed nail heads on the top row of shingles where our kitchen addition roof meets the wall of the old house. Then I look around and see another row of nail heads on another section of roof that is an apron-like thing over the garage doors. Again, it is the top row of shingles where they go up against a wall of siding. I also now see exposed heads on the last cap shingle on the house and garage and shed ridges.
So what do you think? Should I call them back to redo those shingles or put special caulk on the heads? I was able to determine that row of shingles below the nailed ones (on the kitchen roof) have been slid under the flashing which makes me feel better.
Was I foolish to have it done in such cold weather?
This is my first roof as a homeowner so I invite your knowledgeable thoughts.
