Roof Replacement in Nashua, NH

Nashua, the Gate City, is New Hampshire's second-largest city. It grew up around textile mills on the Nashua River, including the Nashua Manufacturing Company, founded in 1823.

The houses we roof in Nashua

According to the U.S. Census Bureau's American Community Survey (2020 to 2024 estimates), Nashua has about 38,800 homes. The median home in the city was built in 1975. About 20 percent were built before 1940, 60 percent before 1980 and 13 percent in 2000 or later. About 50 percent are single-family houses, 16 percent are in buildings with two to four units, and 56 percent are lived in by their owners.

What the housing means for Nashua roofs

• 20 percent of Nashua homes were built before 1940. On roofs that old we expect more than one layer to strip and, under them, plank decks left from wood shingles. Gaps and rotted boards get new sheathing before the shingles go on, priced once the old roof is off.
• 47 percent of homes are in buildings with two or more units. Three-story roofs, and low-slope sections flatter than 4-in-12, need a staging or underlayment plan we set on site, so they are priced after a visit.
• The median Nashua home was built in 1975, before modern attic insulation levels. Ice dams on those houses come from heat leaking into the attic, so we check the ceiling and the attic before we blame the roof.
• 8 percent of Nashua households heat mainly with oil and 6 percent with propane; 70 percent use utility gas. Heat lost through the ceiling is what melts snow on the roof, so attic leaks cost fuel and feed ice dams.
• 44 percent of Nashua households rent. For landlords, a roof is often paired with rental property maintenance on the same building.

Ice barrier, ice dams and the code in Nashua

Nashua is in Hillsborough County, climate zone 5. Where the code's climate table marks ice-dam history, state code section R905.1.2 sets how far up the roof the ice barrier must reach (details). Our Nashua ballparks include it at the eaves and valleys either way.

Permits in Nashua

Whether a roof replacement needs a building permit is set by the town, and it can depend on the scope. Before work starts we confirm it with Nashua's Building Safety Department. Town permit fees, where they apply, are listed separately on the estimate.

An example roofing ballpark for Nashua

Our pricing engine returns $5,900 to $6,300 for one-story ranch, simple gable roof about 40 by 26 feet at a 6-in-12 pitch, one layer off, in architectural asphalt shingles, with travel to Nashua included. That is an example, not a quote. For your own roof, the Instant Ballpark gives an asphalt shingle ballpark from the same engine, or call or text (603) 688-6096.
