Why Mahtomedi is differentWhy do Mahtomedi lakeshore roofs take more wind?
Mahtomedi is on the east side of White Bear Lake, a lake of about 2,400 acres. Summer thunderstorms in Minnesota usually move from west to east, so they cross open water just before they reach Mahtomedi's shoreline. There are no trees or buildings on the lake to slow the wind down, so ridge caps, rakes and siding corners on lake-facing homes take the hardest hits.
Even the school mascot knows it. The Mahtomedi Zephyrs were first named for the 1930s Lincoln Zephyr car, but the name now points to Zephyrus, the Greek god of the west wind. For a roofer, the west wind is the practical part: NOAA's records near Mahtomedi include gusts of 64 mph on August 24, 2021 and 58 mph on July 19, 2023.
Wind damage on a shingle roof is different from hail. We look for shingles that have been lifted and resealed crooked, creases across the tabs, missing ridge caps and loose drip edge along the rakes. On siding we check the corners and the first course above the foundation, where wind gets behind the panels. Lake-side walls get checked first, and every finding goes into a dated photo report.
Big trees add to it. Mahtomedi's older lake streets were platted between 1892 and 1914, and many lots still have the tall oaks and maples that drop limbs in a storm. We photograph limb strikes separately from wind lift, because they get repaired differently.
