What drives the price
- Material. 3-tab asphalt is cheapest, architectural shingles cost a bit more but last longer, and standing-seam metal is the priciest upfront with the longest life.
- Roof size & pitch. Steep, multi-level or cut-up roofs take longer and need more safety setup, which raises labor.
- Number of existing layers. NH allows up to two layers, but a full tear-off (vs. an overlay) adds $600–$1,200 in disposal — and is the only way to inspect the deck.
- Labor (50–60% of the bill). The Northeast’s short season and crew shortage push labor rates above the national average.
- Ice-dam protection. NH code and winters often require ice-and-water shield along the eaves — worth it, but it adds material and labor.
Frequently asked
How long does a new asphalt roof last?
Architectural shingles typically last 25–30 years in NH; 3-tab closer to 20. Metal lasts 40–70 years. Ventilation and ice-dam protection have a big effect on lifespan here.
Overlay or full tear-off?
An overlay (new shingles over old) is cheaper short-term but hides deck damage and shortens lifespan. Most NH roofers recommend a tear-off so the deck can be inspected and ice-and-water shield installed.
When is the best time to replace a roof in NH?
Late spring through early fall. Shingles seal best in warmer weather, and crews are less weather-delayed. Booking in the off-season can sometimes lower the price.
Will insurance pay for a replacement?
Homeowners insurance generally covers sudden damage (storm, fallen tree), not age-related wear. A roofer can document storm damage for a claim, but normal aging is on the homeowner.
