How much does a new roof cost?
Roofers price by the square, which is 100 ft² of roof. Installed prices, including material, tear-off, flashing and labour, by shingle type:
- 3-tab asphalt
- $415–$565 per square
- Architectural shingle
- $475–$650 per square
- Metal
- $1,020–$1,385 per square
A 1,500 ft² footprint is about 18 squares at a standard pitch. With architectural shingles and one old layer torn off, it usually comes to $8,600 to $11,650 installed.
A steep pitch, extra old layers, valleys and rotten decking all push the price up. Your roofer confirms the final quote after measuring the roof and checking its condition.
