The Class 4 upgrade math
Standard HDZ vs Class 4 AS II: $2 per square foot upcharge typically. On a 2,500 sq ft home, $5,000 difference. The Minnesota Class 4 insurance discount of 10–30% on a typical $2,400/year premium = $240–$720/year in savings. Pays back the upcharge in 7–20 years. Over a 25-year roof life, the discount stack reaches $6,000–$18,000 — almost always net-positive.
