Wind, hail and the prairie edge
On the edge of the city, wind arrives with nothing to slow it. Strong gusts can crease shingles, lift ridge caps and work at sealing strips that have not fully sealed down. Roofs installed in cold weather sometimes never seal properly, and those are the first to show loose tabs after a windy spell.
Summer storms bring hail from the plains, and a newer roof is not immune. Hail can bruise the shingle mat, knock granules loose and leave soft spots that do not leak right away. In winter, drifting snow loads valleys and low-pitch sections, and sun on the south slopes can melt snow that refreezes at the eaves, so ice dams are possible even on new houses.
