Sewage backups in Warren County spike on heavy-rain days, about 14.2 a year, when sewer mains fill up and water finds the lowest drain.
Warren County's wettest day in the 2015–2024 record brought 3.85 inches, and about 63 freeze-thaw days a year mean ice dams in some winters.
5% of occupied homes in Warren County heat mainly with wood or propane, below the Kentucky county median of 12.6%.

Local risk profile
With 59,868 homes and around 140,918 residents, Warren County is 542 square miles of southern Kentucky. Besides Bowling Green, the county seat, the biggest communities are Plano, Smiths Grove and Plum Springs. Much of its housing is recent, with a median build year of 1993.
44/100 Water Damage Risk Index: Moderate Warren County ranks 86 of 120 Kentucky counties. See the statewide ranking and method.The three factors where Warren County ranks highest compared with other Kentucky counties.
Warren County is milder than most of Kentucky, but not mild enough to skip winterizing. In the 2015–2024 record the county logged about 15 nights a year at or below 20°F (102nd of 120) and 70 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
The longest cold spell was straight 8 days without the temperature rising above freezing, ending in February 2021. The coldest night reached about -7°F on February 19, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
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 2 and the last spring freeze around Mar 30.
Heavy rain is a bigger factor here than in most of Kentucky. About 14.2 days a year bring an inch or more (17th of 120), most often in February, out of 55.8 inches of total precipitation. On September 1, 2017, 3.85 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 6.21 inches (through September 2, 2017).
The temperature crosses 32°F in both directions on roughly 63 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
34% of homes in Warren County predate 1980, below the Kentucky county median of 44.1%, which ranks 103rd of Kentucky's 120 counties.
40% of homes were built in 2000 or later, more than in most of Kentucky. Newer plumbing rarely corrodes, so damage here tends to come from appliance supply lines, water heaters, sump pumps and storms.
27% date from 1980 to 1999, the window when polybutylene, a gray flexible plastic supply pipe, was used in some homes. It's prone to leaks at the fittings, so it's worth checking for in a house from those years.
Renters occupy 44% of homes. If you rent, the building is usually the landlord's to repair, but your belongings are only covered by renters insurance.
Beyond water
About 75 nights a year in Warren County stay at 65°F or warmer, a sign of muggy summer air (22nd of 120 counties). February 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.
Mold remediation: what to expectHeating fuel matters for fire risk. In Warren County it's 38% utility gas, 57% electric, 5% propane and under 1% 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.
