What moves the price in New Hampshire
Labour
New Hampshire roofers earn a mean of $30.69/hr (BLS OEWS May 2025; 270 employed statewide). Our model weights labour at ~45% of job cost, giving New Hampshire a factor of 1.04 against the national 1.00.
Material choice
Asphalt is the budget end; standing-seam metal, tile and slate cost 2–4× more upfront and last 2–4× longer. Lifespan per dollar often favours metal — compare on the calculator.
Roof shape
Pitch, valleys, dormers and stories all add labour and waste. A steep or cut-up roof can price 10–25% above the same area in a simple gable. Measure yours →
Tear-off vs overlay
Skipping tear-off saves money today and can void warranties and hide deck damage. When each makes sense →

- For a typical 2,000 sq ft roof in architectural asphalt shingles, our model estimates $11,500 to $15,700 in New Hampshire. The range is modelled from national material prices adjusted by a New Hampshire labour factor of 1.04 (BLS OEWS May 2025 roofer wages). It is an estimate, not a quote.
- Why do roof prices differ in New Hampshire?
- Labour is roughly 45% of a replacement job, and roofer wages in New Hampshire average $30.69/hr against a $27.95/hr national mean (BLS OEWS May 2025). Materials are priced close to national, so wages, demand and code requirements explain most of the local difference.
