September brings the most downpours to Rowan County, part of 9.6 heavy-rain days a year. Check the sump first.
Sewage backups in Rowan County spike on heavy-rain days, about 9.6 a year, when sewer mains fill up and water finds the lowest drain.
Rowan County's wettest day in the 2015–2024 record brought 2.94 inches, and about 61 freeze-thaw days a year mean ice dams in some winters.
5% of occupied homes in Rowan County heat mainly with wood or propane, below the North Carolina county median of 11.7%.

51/100 Water Damage Risk Index: Elevated Rowan County ranks 53 of 100 North Carolina counties. See the statewide ranking and method.The three factors where Rowan County ranks highest compared with other North Carolina counties.
For frozen pipes, Rowan County is a typical North Carolina county, which is still plenty. From 2015–2024 it averaged 6 nights a year at 20°F or colder, the range where pipes in exterior walls, crawl spaces and unheated garages freeze, and 63 nights at or below 32°F. That ranks 43rd of 100 counties.
The freeze season here runs December to February, with January the coldest. If you travel then, leave the thermostat at 55°F or above and open sink cabinets on outside walls.
On average the first fall freeze arrives around Nov 6 and the last spring freeze around Mar 29.
Rowan gets fewer downpours than most North Carolina counties, but they still fill basements. Of roughly 46.6 inches of yearly precipitation, the damage comes from the 9.6 days a year with an inch or more, ranked 94th of 100. May, September and October see the most. The single wettest day in the record: 2.94 inches, August 9, 2024. Multi-day storms matter most for basements; the wettest three days on record here totaled 5.3 inches (through August 10, 2024).
The temperature crosses 32°F in both directions on roughly 61 days a year. Each cycle melts and refreezes water at roof edges and in foundation cracks, which is how ice dams and basement seepage get started.
Housing
North Carolina's 100 counties range widely in housing age; Rowan ranks 30th, with 47% of its homes built before 1980.
24% 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 28% 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 15% 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.
Beyond water
Summer nights that don't drop below 65°F, a good marker of humid air, come about 80 times a year here, close to the North Carolina county median of 88.5. Mold grows when indoor humidity stays above about 60%, the EPA's ceiling. A basement dehumidifier set to 50% and drying anything wet within 24 to 48 hours prevents most problems.
Mold remediation: what to expectBy main heating fuel, Rowan County homes break down as 24% utility gas, 68% electric, 4% propane and 2% wood. Heating equipment, cooking and electrical failures cause most home fires nationally. Even a small kitchen fire can leave soot through the whole house, because smoke follows air currents into closets, ducts and attic space.
