Local field notes
For pavement, the useful numbers are not the averages but how often the ground and the surface cross 32 degrees. Water gets into any open crack, freezes, expands and pries the crack wider, then thaws and runs deeper. Derry gets that cycle on roughly 95 days a year, and a further 34 or so days stay frozen all day. Summers are warm rather than extreme, with about 16 days at or above 90 degrees, which matters mostly for how soft a new surface is under turning loads and when sealer and striping cure properly.
NOAA 1991-2020 climate normals for the Manchester-Boston Regional Airport station, about 12 miles from Derry. Derry's own conditions vary a little with elevation and distance from the Merrimack Valley, so treat these as a close local benchmark rather than a measurement taken in town.
Under the pavement
Derry sits in the glaciated landscape of southeastern New Hampshire, where sand and gravel laid down by meltwater sit close to denser glacial till and to the wetter ground along brooks and ponds. That mix is the main reason two lots a mile apart can age very differently, and it is why base and drainage usually matter more here than the thickness of the asphalt on top.
What fails here
Ridges, humps and soft, pumping areas that appear in late winter and early spring, often with cracking along the edges of the heave. Some settle by summer; the cracks they leave do not close.
Likely causes
When to get it looked at: When a heave returns in the same place every spring, or when the surface is pumping water or fines under traffic, the problem is in the base or the drainage and a surface patch will not hold.
Transverse and longitudinal cracks, then wider cracking and potholes where the pavement has been opened up. With about 95 freeze-and-thaw days a year, an unsealed crack is an open invitation every winter.
Likely causes
When to get it looked at: Sealing is worth doing while cracks are narrow and the surrounding pavement is sound. Once the cracks connect into a block pattern, the structure underneath is failing and sealing alone will not fix it.
Puddles that stay after rain, fine cracking in a pattern like alligator skin, and soft spots, usually in low areas of a lot or beside a drainage swale or wetland.
Likely causes
When to get it looked at: Water that returns after every storm, or a failure that keeps coming back after a patch, calls for a look at grading and drainage before any more asphalt goes down.
Scaling and spalling on concrete aprons, curbs and sidewalks, and a general roughening of the surface where salt is applied heavily and water is slow to leave.
Likely causes
When to get it looked at: Scaling that exposes aggregate, or spalls near the edges of entrances and ramps, is worth repairing before the next winter so water cannot get under the surface.
Through the year
Thawing goes from the top down, so for a few weeks the surface layer is saturated and weak over still-frozen ground. This is when heaves and potholes show up, and it is the wrong time for heavy loads on soft pavement. Cold-patch what is unsafe and plan the permanent repairs for when the ground is thawed and dry.
The working window for resurfacing, sealcoating and striping, with about 16 days a year at or above 90 degrees. Hot pavement is soft under turning wheels, so a fresh surface in a busy lot needs to cure before heavy truck traffic.
The last stretch for crack sealing and drainage work before the ground freezes. Roughly 19 days between September and November already have a low at or below freezing, and fall is also a wet season, with about 11 inches of precipitation on average between September and November.
About 81 of the year's 129 freezing days fall in December through February, with about 44 lows at or below 20 degrees. Salt does little below about 15 degrees, so heavier application at those temperatures mostly adds cost and runoff.

Local context
Derry is a commuter town with two village centers and two commercial spines. Most of the demand for paving contractors is retail and institutional lots, plus the driveways and neighborhood roads of a large residential town.
Before you bid
Resurfacing an existing lot in place is a different matter from building or expanding one, and the rules that apply depend on the site. These are the checks worth making before a project is bid; none of this is legal advice.
Local answers
Almost always because water is in the ground under the surface. Where the soil has a lot of silt or very fine sand, freezing draws water upward into ice lenses that lift the pavement, and the spring thaw then leaves a saturated, weak layer on top. Cracks that were left open and drainage that does not carry water away make it worse. A contractor should look at the base and the drainage, not only the surface.
Using NOAA's 1991-2020 normals for the Manchester airport station, about 129 days a year have a low at or below freezing and about 34 stay at or below freezing all day. That implies roughly 95 days a year when the temperature falls below freezing and then rises above it. That last number is our own subtraction, not a published figure, and the station is about 12 miles from Derry.
Resurfacing in place usually does not trigger the state's Alteration of Terrain permit, which starts at 100,000 square feet of disturbance (50,000 near protected waters). Changing the footprint, the grading or the drainage can bring in town site-plan review, and some parcels sit in the town's groundwater protection district. Check with Derry's Planning and Public Works departments for the specific property.
Salt tends to be harder on concrete, which scales when salt-laden water sits on it and freezes, than on asphalt, and it is a major water-quality issue. The New Hampshire Department of Environmental Services reports that private roads and parking lots account for a large share of the salt in some southern watersheds, and it runs the Green SnowPro certification to help applicators use less.
The USDA Web Soil Survey is free and shows the mapped soil type, its drainage class and the typical depth to the water table for any address. It describes general conditions across a map unit, so for a large lot or a repeated failure a geotechnical boring or test pit gives the real answer.

Soil, drainage and permit requirements vary parcel by parcel and by project, so confirm them with the town, the state agency and a qualified professional before work is scoped.
Regional field notes
Cold, freeze-thaw climate
In cold northern climates, the single biggest enemy of pavement is water that freezes and thaws. Meltwater and rain seep into small cracks, freeze overnight, expand, and pry the crack wider — then the cycle repeats dozens of times each winter. Combined with snowplowing, de-icing salt, and a short paving season, this makes proactive crack and moisture management far more important here than in mild climates.
Water trapped in cracks and base layers expands about 9% when it freezes, widening cracks and undermining the surface. Repeated cycles turn hairline cracks into potholes, especially in late winter and early spring.
When moisture in the sub-base freezes it can lift and distort the pavement (frost heave), then leave voids as it thaws. Good drainage and a well-compacted base matter more here than almost anywhere else.
De-icing chemicals and plow blades accelerate surface raveling and scrape sealcoat and striping. Markings and thin surface treatments wear out faster and need more frequent renewal.
Hot-mix asphalt and sealcoat both need warm, dry conditions to cure. The workable window is compressed into the warmer months, so scheduling paving and maintenance early is important.
