Every hail storm to hit Bismarck-Mandan since 1962.

221 days of one-inch-or-larger hail across Burleigh and Morton counties. 120 of them were golf ball size or bigger. We built this because it is the fastest way to answer the question nobody can ever remember the answer to: when was my roof last replaced?

Why this dates your roof

In this market almost nobody replaces a roof because it wore out. They replace it because hail totalled it and insurance paid. So if you cannot remember the year your roof went on, find the storm you do remember and you have your answer within a season.

The five that re-roofed neighbourhoods

17 June 2016 — 3.25 inch, north Bismarck hardest, $50.3M
29 July 2024 — 4.50 inch softball, $12.3M
21 July 2005 — 2.50 inch, $93M, "extensive and widespread"
21 July 2022 — 2.50 inch, two storms the same day
27 June 2025 — 2.75 inch, NWS logged roof damage by subdivision name

Named subdivisions in the record

The National Weather Service occasionally names the neighbourhood in its own storm narrative. Falconer Estates (10 July 2011, roof and gutter damage to about a dozen homes). The Ranch and Heritage Reserve (27 June 2025, roof and siding damage). Copper Ridge south of Lincoln took 96 mph straight-line wind on 20 June 2025, $5M, several homes severely damaged.

How to use it

Find the most recent storm on this list that hit your area. If your shingles look newer than that storm, that is probably when they went on. If they look older than it, your roof survived a hit it may not have fully recovered from — worth a free look.
