Roofing in Garrison, ND

Garrison holds a city listing on North Dakota's code-enforcement directory at 701-463-2600, and McLean County is not on the county side of it. Outside the city limits the permit goes instead to the county Land Use Administrator at the Washburn courthouse, on 701-462-8541, at one tenth of one percent of construction cost with a ninety dollar minimum and a five hundred dollar residential cap.

So the lake places and the town houses sit under two different offices, and which one applies to you depends on a line that is not obvious from the road. It is worth establishing before work starts rather than afterwards, particularly on a cabin that may sit outside the city on land the county administers.

The housing carries the dam era in it. Sixteen percent of Garrison's units were built between 1950 and 1959, during and after Garrison Dam construction, with 18 percent dating to 1939 or earlier and 17 percent to the 1970s, a median year of 1967, and a further 11 percent built between 2010 and 2019. Three distinct eras of decking inside one town of 1,462.

Garrison sits above Lake Sakakawea with a real mix of year-round houses and places that stand empty through the coldest months, and an unheated building tracks outdoor temperature far more closely than a lived-in one does.

For a seasonal building we care more about ridge vent selection, external baffle design and the gable end detail than about attic insulation depth. That removes most of the interior heat that drives ice damming and replaces it with wind-driven snow entering at the ridge. We inspect part-year buildings at both ends of the year, and the useful visit is the February one, because that is when the fault is being loaded.

Hail here has been regular and mostly moderate: seventeen reports of an inch or more across fourteen separate days since 2006, the largest at two and a half inches on 27 June 2025, the most recent big stone anywhere in our footprint. Gusts of 71 and 70 knots were logged on 7 July 2020.

Around 434 of roughly 574 occupied units are on utility gas and 43 are manufactured homes, which is two very different roof types under one town name. Fort Stevenson State Park brings traffic through and we are here on a normal route.

Roofing work we do in Garrison, ND

Bismarck Roof Pros covers the same range of work in Garrison that we do in Bismarck — nothing is carved out because the address is a few miles up the road:

  • Roof ReplacementSizing a replacement here starts with a number most bids never mention: 159 degrees. That is the distance between Bismarck's record low of 45 below zero and its record high of 114, both on the National Weather Service books for this station.
  • Roof Leak RepairLeaks in this town keep a calendar. A joint squeezed shut on a 95-degree August afternoon sits wide open at 20 below in January, so the drip you could never reproduce with a hose in summer is often the one staining the ceiling in February.
  • Storm Damage RestorationCentral North Dakota storms arrive at the hot end of the year. That matters more than most restoration scopes admit, because the same roof responds differently to the same impact depending on how warm it was when the storm hit.
  • Hail Damage RoofingImpact ratings are lab numbers taken at room temperature. That is the single most useful thing to know about hail products in a market that can hail in June and sit 30 below in January, and almost nobody selling shingles here mentions it.
  • Wind Damage RoofingMost wind failures we open up in Bismarck did not start with wind. They started at the edge metal, and by the time a gust found the roof the edge had already been quietly coming apart for six or seven years.
  • Roof InspectionsOne inspection sees a roof in one thermal state. In a market that travels 159 degrees between its records, that is like judging a door by how it fits in August.

About Garrison, ND — and why local matters here

Garrison sits in McLean County with a population of roughly 1,462, close enough to Bismarck that crews move between the two constantly. Local landmarks and corridors residents know well include Fort Stevenson State Park, Wally the Walleye.

Local knowledge is not a marketing line here. Garrison properties share soil, weather, permit rules and construction eras with the rest of McLean County, and a roofing contractor who works the area weekly already knows what fails locally and what holds up. That is the difference between a bid and an accurate bid.
