Roof leaks here come from summer downpours and, with about 104 freeze-thaw days a year, from winter ice dams. Most show up as ceiling stains in the room below.

Local risk profile
Kalkaska County covers 560 square miles of northern Lower Michigan, with about 18,239 residents and 11,690 homes. Besides Kalkaska, the county seat, the biggest communities are Rapid City, South Boardman and Manistee Lake. The county's median home was built in 1980.
38/100 Water Damage Risk Index: Moderate Kalkaska County ranks 67 of 83 Michigan counties. See the statewide ranking and method.The three factors where Kalkaska County ranks highest compared with other Michigan counties.
Kalkaska is on the colder side of Michigan for pipes. It averaged 163 freezing nights a year over 2015–2024, 68 of them at 20°F or colder, cold enough for pipes in outside walls and crawl spaces to freeze. Among 83 Michigan counties that's 21st.
The longest cold spell was straight 41 days without the temperature rising above freezing, ending in March 2015. The coldest night reached about -27°F on February 20, 2015. Burst pipes usually show up when a spell like that breaks and the ice thaws.
Most freezing nights fall from November to April, 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.
On average the first fall freeze arrives around Oct 15 and the last spring freeze around May 20.
Rainfall is about average for Michigan. Of roughly 35.2 inches of yearly precipitation, the damage comes from the 3.7 days a year with an inch or more, ranked 46th of 83. June, August and October see the most. The single wettest day in the record: 3.03 inches, October 24, 2017. Multi-day storms matter most for basements; the wettest three days on record here totaled 5.41 inches (through October 25, 2017).
About 104 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
Roughly 51% of the county's housing was built before 1980. That puts Kalkaska among the newer housing stocks of Michigan's 83 counties.
Older and newer homes sit side by side here: 17% predate 1960 and 19% are from 2000 or later. Corroded pipe is the typical failure in the first group, burst supply hoses in the second.
30% 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.
Manufactured and mobile homes make up 14% 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.
33% of homes were vacant at survey time. A leak in an empty rental or seasonal house can run for days before anyone notices, which is why those losses tend to be larger.
Beyond water
Kalkaska County averages 5 warm, muggy nights a year (lows of 65°F or more) and gets the most rain in October. 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 Kalkaska County it's 37% utility gas, 7% electric, 42% propane and 13% wood. Wood and propane heat are 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.
