Roof leak or storm: what to do in your Belmont County home right now
In Belmont County, 3.52 inches fell on the wettest day of the 2015–2024 record. Storms like that, and ice dams in snowy winters, cause most roof leaks.
Belmont County covers 532 square miles of eastern Ohio, with about 65,473 residents and 31,522 homes. St. Clairsville is the county seat; Martins Ferry, Barnesville and Bellaire are the next largest communities. The county's median home was built in 1965.
The three factors where Belmont County ranks highest compared with other Ohio counties.
Weather
For frozen pipes, Belmont County is a typical Ohio county, which is still plenty. It averaged 113 freezing nights a year over 2015–2024, 30 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 49th.
The longest cold spell was straight 13 days without the temperature rising above freezing, ending in January 2018. The coldest night reached about -8°F on February 20, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
The freeze season here runs November to March, 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 Oct 27 and the last spring freeze around Apr 25.
Heavy rain is a bigger factor here than in most of Ohio. About 6.5 days a year bring an inch or more (27th of 88), most often in June, out of 46.3 inches of total precipitation. On September 10, 2018, 3.52 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 5.76 inches (through September 11, 2018).
Freeze-thaw days, below freezing overnight and above it by afternoon, come about 91 times a year here. They're the main driver of ice dams and of water working its way through foundation cracks in late winter.

Housing
What Belmont County's homes are made of
71% of homes in Belmont County predate 1980, above the Ohio county median of 61.1%, which ranks 19th of Ohio's 88 counties.
46% 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.
The Census counted 14% 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 Belmont County
Mold
About 28 nights a year in Belmont County stay at 65°F or warmer, a sign of muggy summer air (71st of 88 counties). June is the wettest month. 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.
By main heating fuel, Belmont County homes break down as 47% utility gas, 30% electric, 10% propane and 3% wood. Fires here are likelier to start in the kitchen or the wiring than in the furnace. After any fire, keep the HVAC off until ducts are checked, or soot will travel through the house.
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.

How often do pipes freeze in Belmont County?
Pipe-freeze weather, 20°F or colder, comes about 30 nights a year in Belmont County, from November to March. Pipes along outside walls and in crawl spaces go first.
What causes the most water damage in Belmont County?
Based on the county's housing and weather data, the biggest local factors are freeze-thaw and ice dams, aging plumbing and leaks in empty homes. Appliance supply lines and water heaters cause leaks everywhere.
Will my insurance cover water damage in Belmont 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 6.5 heavy-rain days a year here.
How fast does mold start in a Belmont County home?
The EPA advises drying wet materials within 24 to 48 hours. In June, the county's wettest month, and on the 28 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.
