i did like 50 squares myself...I went and shingled a garage today. It was small at only 3.5 square. The neighbors dog was barking up a storm when I got there. I told them it would only be 2 hours plus cleanup. But it took 2 hours and 1 minute. Plus clean up. But in my defense it was 2 stories up and there was 30 MPH winds.
