What's the lifespan of a roof in the Minnesota climate?

Minnesota is hard on roofs, so they don't last as long here as the marketing on a shingle bundle suggests. A standard asphalt shingle roof in Coon Rapids typically gives you somewhere in the 15-to-25-year range, and our conditions push toward the shorter end: brutal freeze-thaw cycles, heavy snow load and ice dams in winter, intense summer sun and UV, and the regular hail and wind storms that roll through the north metro. Quality of the shingle, the steepness and ventilation of the roof, and installation all move that number. During an inspection we estimate the roof's apparent age and remaining life, look for storm damage like granule loss and bruising, check flashing and penetrations, and note whether multiple layers were installed over old shingles, which shortens life and complicates the next replacement. We also evaluate attic ventilation and insulation, because poor ventilation cooks shingles from below and feeds ice dams. If a roof is near the end, that's a major budgeting and negotiating item, since replacement is a significant cost. Don't assume a roof is fine just because it isn't leaking yet.
