My insurance paid me $250-300 a square for owens corning 3 tab, 45 square. I had owens duration put on with ice and water on the whole roof on half of it, synthetic underlayment on the rest, with owens caps and starter, new valleys, drip gutter edge, and aprons, plus tear off one roof layer for $13,500, about 275 a square. Roofer said 3 tab or duration same price due to labor savings, plus that wide strip lets the less than qualified people they hire, as nobody wants to work anymore, get nail them nailed right. It was done april 2020. I say about $9000, I kinda got a covid deal as nobody was working much after the march shutdown. 15 square was 12/12 pitch, the rest was 6/12 and below.
