St Francis has a population of 8,372 and a median household income of $111,198, which tells you something about the area. (Data source: U.S. Census Bureau / Data Commons.) These are newer, well-kept homes on larger lots, and homeowners here take maintenance seriously. A lot of the housing stock was built in the 1990s and 2000s, which means a lot of roofs are hitting that 25-to-30-year mark right now. That's exactly when asphalt shingles start to go.
The climate here is no joke. St Francis sits at about 45.4 degrees north latitude, which puts it squarely in Minnesota's freeze-thaw zone. Winters bring heavy snow loads, ice dams, and hard temperature swings that work on your shingles season after season. Spring storms roll through Anoka County with high winds and hail. By the time summer arrives, UV exposure bakes whatever the winter left behind. That cycle repeats every year, and roofs wear out faster here than in milder climates.
