How much does a new roof cost?

Asphalt architectural shingles typically run about $450–$700 per roofing square (100 ft²) installed, 3-tab a little less, and metal roughly $1,000–$1,600 per square. A standard detached home lands in the high four to low five figures once tear-off, flashing, underlayment, and labour are included.

This calculator shows an honest low–high range because steep pitch, multiple old layers, valleys, and decking repair all move the final number. A contractor confirms the measurement and condition on-site.
