Roof Replacement in New Hampshire is 15% above the national average of $7,470. This is primarily due to higher labor costs and stronger demand in New Hampshire.
New Hampshire experiences a cold humid continental climate with long, snowy winters and short, mild summers. Frost lines of 48 inches or more and deep snow loads compress most exterior construction into a May-through-October window, and the White Mountain region faces some of the highest design snow loads in the country. For roof replacement projects specifically, this means timing and material selection are key factors in both cost and quality.
New Hampshire's costs are close to the national average, reflecting a balanced supply-demand dynamic in the local construction market.
