Noble County covers 398 square miles of eastern Ohio, with about 14,282 residents and 5,798 homes. The county seat is Caldwell, and Belle Valley, Sarahsville and Summerfield round out the largest towns. Half the homes here were built before 1978, half after.
The three factors where Noble County ranks highest compared with other Ohio counties.
Weather
Pipe-freeze risk in Noble County sits near the middle of the state. It averaged 109 freezing nights a year over 2015–2024, 29 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 88 Ohio counties that's 56th.
On February 24, 2015 the low fell to about -8°F, and in the stretch ending January 2018 the county went 13 days in a row below freezing. Leaks from split pipes typically appear the day the thaw arrives.
Most freezing nights fall from November to March, 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.
Freezing nights typically start around Oct 27 and end around Apr 21.
Rainfall is about average for Ohio. Of roughly 43.8 inches of yearly precipitation, the damage comes from the 5.9 days a year with an inch or more, ranked 38th of 88. June, July and September see the most. The single wettest day in the record: 2.55 inches, November 6, 2017. The worst three-day stretch dropped 4.17 inches, ending September 10, 2018, the kind of soaking that overwhelms sump pumps and storm sewers.
The temperature crosses 32°F in both directions on roughly 90 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
What Noble County's homes are made of
Roughly 53% of the county's housing was built before 1980. That puts Noble among the newer housing stocks of Ohio's 88 counties.
Older and newer homes sit side by side here: 31% predate 1960 and 20% are from 2000 or later. Corroded pipe is the typical failure in the first group, burst supply hoses in the second.
About 27% 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.
16% of homes are manufactured or mobile homes, above the Ohio county median of 5.9%. Their water lines run under the floor behind the skirting, so a torn skirt or failed heat tape freezes them faster than lines in a site-built house.
The Census counted 20% of homes as vacant, above the Ohio county median of 8.4%. Empty houses are where a small leak turns into a large claim, because nobody is there to hear it.

Beyond water
Mold and fire damage in Noble County
Mold
About 30 nights a year in Noble County stay at 65°F or warmer, a sign of muggy summer air (65th of 88 counties). June is the wettest month. 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.
By main heating fuel, Noble County homes break down as 44% utility gas, 19% electric, 16% propane and 11% wood. Wood and propane heat are above the Ohio norm. Annual chimney and vent inspection, which the NFPA recommends, is one of the most effective fire-prevention habits for these homes.
Rank 1 is the highest value. Bars run from the lowest to the highest Ohio county; the tick marks the median; orange means higher water damage risk than the median, green means lower.
Questions

How often do pipes freeze in Noble County?
Pipe-freeze weather, 20°F or colder, comes about 29 nights a year in Noble County, from November to March. Pipes along outside walls and in crawl spaces go first.
What causes the most water damage in Noble County?
Based on the county's housing and weather data, the biggest local factors are leaks in empty homes, freeze-thaw and ice dams and wood and propane heat. Appliance supply lines and water heaters cause leaks everywhere.
Will my insurance cover water damage in Noble County?
Pipe bursts and appliance failures are typically covered; slow leaks, seepage and floodwater typically aren't. Ask your agent about water backup coverage, given 5.9 heavy-rain days a year here.
How fast does mold start in a Noble County home?
The EPA advises drying wet materials within 24 to 48 hours. In June, the county's wettest month, and on the 30 muggy summer nights a year when lows stay at 65°F or above, basements dry slowly on their own, so start fans and dehumidifiers the same day.
Water won't wait. Neither should you.
Peak risk months in Noble County: freezing from November to March, heavy rain in June, July and September.
