I had a complete tearoff and re-roof done 2 summers ago. Including replacing 6 sheets of plywood, and installing gutter screens and heat cables on the lower level (split level house), it was $12k.
I had 42 square complete tear off and replacement with architect shingles 4 years ago $11,000. Neighbor had his done a few weeks ago. Same company. His roof was only around 36sq. $17,000.
