Why Londonderry differs from the national price
Londonderry is in Rockingham County, which the Bureau of Labor Statistics counts in the Boston-Cambridge-Newton, MA-NH metropolitan area (mostly Massachusetts). The median wage there for roofers is $31.90 an hour against $26.65 nationally, so the labor part of a national price is scaled by 1.197 (+19.7%). That area is mostly Massachusetts; the New Hampshire statewide median for the same trade is $28.76, so a Londonderry quote may land nearer the low end of the range shown.
On this job the labor portion is $3,000 to $6,000 at national rates and $3,600 to $7,200 at Londonderry rates, so the midpoint rises $890 above the national figure. Against the New Hampshire statewide wage it is $530 higher. Materials are priced at the national figure: shingle, lumber and equipment prices are set by distributors, not by a town.
A second published benchmark points the same way for the region: Remodeling's 2025 Cost vs Value report prices its “Roofing Replacement, Asphalt Shingles” job at $31,850 nationally and $35,700 in New England, and its “Roofing Replacement, Metal” job at $51,850 nationally and $56,300 in New England. Those are fixed specification jobs, not per-square-foot prices, so they are shown for comparison only.
Londonderry at a glance
Londonderry had 28,437 residents in the state's 2025 estimate, up 17.9% from 24,129 in 2010, faster than the state's 7.5% over the same years. Its density of 656 people per square mile puts it 10 of 19 among the towns on this site.
85.6% of Londonderry's occupied homes are lived in by their owners, more than the 72.8% statewide, and the median owner-occupied home is valued at $505,200 (New Hampshire: $402,500). The midpoint estimate for this roof works out to 2.2% of that median value.
Taking off the old roof
Tear off the old roof adds $1 to $5 per sq ft nationally (“The cost to tear off a roof is $1 to $5 per square foot for labor to remove the old material”). That work is all labor, so at Londonderry's index it is $2,400 to $11,950 for 2,000 sq ft, on top of the estimate above.
Before asking for quotes
- The Londonderry building department can say for free whether this job needs a permit and what it will cost; the schedule linked above is its own published document.
- Written quotes that list the same scope (area, material line, removal, disposal, permit) can be compared line by line; the quote comparison guide walks through it with these numbers.
- A quote far below $8,600 or above $13,200 is not wrong in itself, but it is worth asking what it includes or leaves out.
