“Express Building Permit: For Fences, Roofing (Re-Shingle only), Siding, Sheds (200 sq ft or less) and Windows ONLY”
“Fees for building permit applications are $9.00 per $1,000.00 of construction cost (rounded up if only a portion of 1,000), plus a $10.00 application fee.”
“Example: $4,300 construction cost would be (5*9)+10= $55.00”

Why Rochester differs from the national price
Rochester is in Strafford County, which the Bureau of Labor Statistics counts in the Boston-Cambridge-Newton, MA-NH metropolitan area (mostly Massachusetts). The median wage there for carpenters is $36.16 an hour against $29.12 nationally, so the labor part of a national price is scaled by 1.242 (+24.2%). That area is mostly Massachusetts; the New Hampshire statewide median for the same trade is $29.42, so a Rochester quote may land nearer the low end of the range shown.
On this job the labor portion is $3,000 to $9,000 at national rates and $3,750 to $11,200 at Rochester rates, so the midpoint rises $1,450 above the national figure. Against the New Hampshire statewide wage it is $1,400 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 “Siding Replacement, Vinyl” job at $17,950 nationally and $17,600 in New England, and its “Siding Replacement, Fiber-Cement” job at $21,500 nationally and $20,700 in New England. Those are fixed specification jobs, not per-square-foot prices, so they are shown for comparison only.

66% of Rochester's occupied homes are lived in by their owners, fewer than the 72.8% statewide, and the median owner-occupied home is valued at $279,100 (New Hampshire: $402,500). The midpoint estimate for this siding job works out to 4.8% of that median value.
Taking off the old siding
Remove the old siding adds $0.70 to $2 per sq ft nationally (“$0.70 to $2.00 per square foot (old siding removal)”). That work is all labor, so at Rochester's index it is $1,300 to $3,750 for 1,500 sq ft, on top of the estimate above.
Before asking for quotes
- The Rochester 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 $6,750 or above $20,200 is not wrong in itself, but it is worth asking what it includes or leaves out.
