About roofing in New Hampshire

A residential roof replacement covers tear-off of the existing roofing, inspection and repair of the decking, new underlayment, drip edge, flashing, vents, and shingle installation. For a typical 2,000 square foot home with a moderate pitch, that's a one-week job for an established crew.

Asphalt shingles are still the dominant residential roofing material in the US — about 80% of replacements. Tile is common in the Southwest and on Spanish-style homes; metal roofing is growing in mountain and coastal regions; cedar shake is niche. Material choice can swing the total cost 2-3× even before you account for regional labor differences.

What moves the price

Material choice

3-tab asphalt: $90–$130 per square (100 sq ft). Architectural / dimensional asphalt: $130–$200 per square. Metal standing-seam: $400–$900 per square. Clay or concrete tile: $400–$1,200 per square. Cedar shake: $400–$700 per square. The material is usually 35–50% of the total job cost; the rest is labor, tear-off, and accessories.

Roof complexity

A simple gable roof is the cheapest installation. Hip roofs add 10–15%. Multiple dormers, valleys, skylights, and chimneys add labor at every penetration. A complex roof can cost 30–60% more per square than a simple one of the same area.

Tear-off vs overlay

Most jurisdictions allow only one shingle layer; if your existing roof already has two, you must tear off. Tear-off adds $1.50–$3.50 per square foot in labor plus $400–$900 in disposal fees. Some areas now require tear-off regardless because layered roofs hide damage and complicate insurance inspections.

Decking repair

Once the old roof is off, you may find soft or rotted sheathing — typically 5–15% of the deck needs replacement on a 20+ year roof. Budget $70–$120 per 4x8 sheet of OSB or plywood installed. On bigger replacements (1,500+ sqft) you'll often hit $500–$2,000 in deck repair you didn't see in the original bid.

Permit and disposal fees

Permits run $150–$700 depending on jurisdiction. Disposal of 20+ year asphalt is typically by the cubic yard at a transfer station — $400–$1,000 for a 2,000 sq ft tear-off. Some states charge tipping fees on top.

Wind, snow, and impact ratings

Code-required wind ratings vary by climate zone. Coastal hurricane zones require 120–150 mph rated shingles installed with a tighter nailing pattern (6 nails per shingle vs 4). Hail-prone regions in the Midwest and Plains often install Class 4 impact-rated shingles that earn an insurance discount; these run 15–25% more in material.

Roofing cost across New Hampshire metros

Within New Hampshire the spread between metros is usually 25–40% of the state midpoint. Major metros pay more than rural areas because of labor demand, permit complexity, and material delivery overhead.

  • Manchester / Nashua — typical home build $180–$410/sq ft range
  • Concord — typical home build $165–$380/sq ft range
  • Seacoast (Portsmouth) — typical home build $200–$460/sq ft range
  • Lakes Region — typical home build $190–$430/sq ft range

Frequently asked questions

How much does a roof replacement cost in New Hampshire?
A typical asphalt shingle roof replacement in New Hampshire runs $11,800–$26,200 for a 1,800–2,200 sq ft home with standard architectural shingles, tear-off included. That's roughly $5.90–$13.85 per square foot installed. Upgrading to metal or tile doubles or triples that range.
What does the New Hampshire cost include?
The $11,800–$26,200 range covers labor, materials, tear-off and disposal of one existing layer, new underlayment, drip edge, flashing, and ridge venting. It does not include decking repair (if needed), skylight replacement, gutter work, or solar panel removal and reinstall.
Why is roofing more expensive in some New Hampshire metros than others?
Within New Hampshire, the spread is driven by local labor availability, permit complexity, and disposal fees. Major metros pay 15–35% more than rural counties for the same scope. Coastal and hurricane-prone areas in New Hampshire add a wind-rating premium of 8–15% on top of metro-level pricing.
When should I replace vs repair my New Hampshire roof?
If the roof is under 12–15 years old and the damage is localized (a few missing shingles, one leak, isolated flashing), repair. If it is 18+ years old, has multiple leaks, or shows widespread granule loss, replacement is more cost-effective than ongoing repairs. New Hampshire's climate accelerates aging in some cases — sun-baked southern asphalt typically gives 18–22 years versus 25–28 in mild northern climates.
Should I file an insurance claim for storm damage in New Hampshire?
If the damage looks weather-related and your deductible is reasonable relative to the replacement cost, yes. Get a contractor inspection and photo documentation before calling the adjuster. Many New Hampshire insurers have specific rules around the age of the roof (full ACV vs depreciated payout) so verify your policy. Some states have public adjuster regulations that affect how the claim is handled.
