With 11,584 homes and around 24,155 residents, Shelby County is 796 square miles of eastern Texas. Besides Center, the county seat, the biggest communities are Tenaha, Timpson and Joaquin. The county's median home was built in 1984.
The three factors where Shelby County ranks highest compared with other Texas counties.
Weather
For frozen pipes, Shelby County is a typical Texas county, which is still plenty. In the 2015–2024 record the county logged about 2 nights a year at or below 20°F (126th of 232) and 24 below freezing. Twenty degrees is roughly where uninsulated pipes start to freeze.
Cold snaps are the real risk. The worst in the record lasted 4 days below freezing (ending February 2021), and the low bottomed out near 2°F on February 16, 2021.
With only about 24 freezing nights a year, many homes here aren't built for cold, so a single arctic outbreak can burst pipes across the county. The record low in this data was about 2°F, on February 16, 2021.
Heavy rain is a bigger factor here than in most of Texas. About 17.8 days a year bring an inch or more (5th of 232), most often in April, out of 59 inches of total precipitation. On March 10, 2016, 4.73 inches fell in a single day. Multi-day storms matter most for basements; the wettest three days on record here totaled 10 inches (through March 11, 2016).
About 23 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
What Shelby County's homes are made of
43% of homes in Shelby County predate 1980, close to the Texas county median of 45.8%, which ranks 136th of Texas's 232 counties.
The mix runs from 16% built before 1960 to 26% built since 2000, so older neighborhoods bring aging pipe while newer subdivisions bring failed appliance lines and water heaters.
31% 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.
32% of homes are manufactured or mobile homes, above the Texas county median of 13.4%. 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.
With 19% of homes empty at survey time, landlords and seasonal owners should shut off the main or schedule checks in winter. An unheated vacant house is also where many policies limit freeze coverage.

Beyond water
Mold and fire damage in Shelby County
Mold
About 133 nights a year in Shelby County stay at 65°F or warmer, a sign of muggy summer air (107th of 232 counties). May 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, Shelby County homes break down as 24% utility gas, 67% electric, 6% propane and 3% wood. Wood 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.
Rank 1 is the highest value. Bars run from the lowest to the highest Texas county; the tick marks the median; orange means higher water damage risk than the median, green means lower.
Questions
Shelby County water damage FAQ
Which towns in Shelby County does this cover?
Calls are routed to restoration companies that serve all of Shelby County, including Center, Tenaha, Timpson, Joaquin, Huxley and Shelbyville, plus the townships and rural areas around them. If the first company can't reach you quickly, ask to be connected with another.
How often do pipes freeze in Shelby County?
Pipe-freeze weather, 20°F or colder, comes about 2 nights a year in Shelby County, from midwinter. Pipes along outside walls and in crawl spaces go first.
What causes the most water damage in Shelby County?
Based on the county's housing and weather data, the biggest local factors are heavy rain and basements, mobile home freeze-ups and leaks in empty homes. Appliance supply lines and water heaters cause leaks everywhere.
Will my insurance cover water damage in Shelby 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 17.8 heavy-rain days a year here.
How fast does mold start in a Shelby County home?
The EPA advises drying wet materials within 24 to 48 hours. In May, the county's wettest month, and on the 133 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.
