Roof replacement prices in Derry by material
Each row starts from the installed price per square foot of roof published in a national cost guide, then moves only the labor part of that price by Derry's labor index. For 2,000 sq ft:
| Material | National | Derry | Midpoint |
|---|---|---|---|
| Asphalt 3-tab shingles | $6,000–$10,000 | $6,600–$11,200 | $8,900 |
| Architectural asphalt shingles | $8,000–$12,000 | $8,600–$13,200 | $10,900 |
| Metal roofing | $10,000–$32,000 | $10,600–$33,200 | $21,900 |
By size
| Roof area (sq ft) | Derry estimate | Permit at midpoint |
|---|---|---|
| 1,200 sq ft | $5,150–$7,900 | $67.66 |
| 1,500 sq ft | $6,450–$9,900 | $75.82 |

Permit fee in Derry
General rate The fee schedule has no separate line for this work; the town's general residential building-permit rate is shown as what it would charge if the building department requires a permit for it.
“108.2.1: application fee of $35 for residential and $45 for commercial plus an additional fee of $5 per $1,000 of construction cost.”
Applied to a 2,000 sq ft roof estimated at $8,600 to $13,200, that gives $77.95 to $100.91, about 0.82% of the midpoint price. Among the 16 towns on this site whose schedules cover this work, Derry ranks 2 from the cheapest; Bow is lowest at $40 and Hartford highest at $352.86 for its own midpoint job.
Schedule: Town of Derry Code, Chapter 30 Building and Property Maintenance Codes, § 30-4 (effective 1-3-2017, amended 5-15-2025). The building department decides whether a permit is required and what valuation it accepts; the national guide puts roof permits at $100–$500.
Why Derry differs from the national price
Derry 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 Derry 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 Derry 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.
Derry at a glance
Derry had 34,691 residents in the state's 2025 estimate, up 4.8% from 33,109 in 2010, slower than the state's 7.5%. Its density of 973 people per square mile puts it 9 of 24 among the towns on this site.
The Census Bureau's QuickFacts page for Derry covers only the Derry census-designated place, not the whole town, so its housing figures are not used here.
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 Derry'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 Derry 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.
