Pipes freeze in Bertie County on about 4 nights a year, mostly January. Older homes, 22% of the stock here, are most at risk.
Heavy rain days of an inch or more come about 11.9 times a year here, most often in September. A sump pump that hasn't run since last season is a common weak point.
Backups often follow heavy rain, which Bertie County gets about 11.9 days a year, when storm water overloads sewer mains and pushes up through the lowest drain in the house.
Roof leaks here come from summer downpours and, with about 46 freeze-thaw days a year, from winter ice dams. Most show up as ceiling stains in the room below.
31% of occupied homes in Bertie County heat mainly with wood or propane, above the North Carolina county median of 11.7%.
Muggy summer nights, lows of 65°F or more, come about 98 times a year in Bertie County. Mold after a leak spreads fastest from June through August.
Local risk profile
About 17,170 people live in Bertie County, 699 square miles in northeast North Carolina, in roughly 8,984 homes. Windsor is the county seat; Aulander, Lewiston Woodville and Roxobel are the next largest communities. The county's median home was built in 1981.
58/100 Water Damage Risk Index: Elevated Bertie County ranks 29 of 100 North Carolina counties. See the statewide ranking and method.The three factors where Bertie County ranks highest compared with other North Carolina counties.
For frozen pipes, Bertie County is a typical North Carolina county, which is still plenty. From 2015–2024 it averaged 4 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 48 nights at or below 32°F. That ranks 58th of 100 counties.
Cold snaps are the real risk. The worst in the record lasted 3 days below freezing (ending February 2015), and the low bottomed out near 4°F on January 7, 2018.
Most freezing nights fall from January, peaking in January. Disconnect garden hoses and shut off outdoor spigots before the first hard frost, and keep the heat at 55°F or higher if you'll be away.
On average the first fall freeze arrives around Nov 19 and the last spring freeze around Mar 18.
Rainfall is about average for North Carolina. The county gets about 52.8 inches of rain and melted snow a year, with 11.9 days of an inch or more (44th of 100). Those downpours cluster in January, April and September, when sump pumps and gutters are tested hardest. The wettest day on record brought 6.27 inches on October 9, 2016. Multi-day storms matter most for basements; the wettest three days on record here totaled 7.94 inches (through September 22, 2016).
About 46 days a year swing from below freezing at night to above freezing by day. Those freeze-thaw cycles feed ice dams on roofs, open cracks in foundations and driveways, and stress pipes that are already marginal.
Housing
North Carolina's 100 counties range widely in housing age; Bertie ranks 23rd, with 48% of its homes built before 1980.
22% were built before 1960. Homes from that era often still have galvanized steel supply pipe, which rusts from the inside until it pinholes, and cast iron drains that crack with age. Slow leaks behind walls are a common start to water damage in these houses.
About 30% of homes went up between 1980 and 1999. Some houses from the late 1970s to the mid-1990s were plumbed with polybutylene, a gray plastic pipe known for failing at fittings. A plumber can tell you in a few minutes whether you have it.
Manufactured and mobile homes make up 31% of the housing here. Water lines in the underbelly depend on intact skirting and working heat tape, and they're usually the first to freeze in a cold snap.
21% of homes were vacant at survey time. A leak in an empty rental or seasonal house can run for days before anyone notices, which is why those losses tend to be larger.
Beyond water
Bertie County averages 98 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in September. Keep indoor humidity under 60%, as the EPA advises, and dry any leak within 24 to 48 hours; in a humid month a wet basement left alone won't dry by itself.
Mold remediation: what to expectMain heating fuel in Bertie County's occupied homes: 3% utility gas, 60% electric, 29% propane and 1% wood. Propane heat is more common here than the state median. Have chimneys swept and fuel-burning appliances serviced each fall, and keep three feet clear around stoves and space heaters.
