What repeated hail does to a shingle roof
Missouri storms do not leave roofs alone. Each hail event can remove granules, bruise the mat underneath and loosen the seal between shingles. One storm may do little visible harm, but several over the years add up, and roofs in the eastern metro have lived through plenty of spring weather.
Wind adds its own damage by lifting and creasing tabs, particularly along ridges and rakes. Cheaper builder-grade shingles from the boom years are thinner and may wear faster. Checking collateral damage helps too, since dented gutters, vents and window screens indicate how hard a storm hit. A written inspection that lists what was found, slope by slope, is useful both for repair planning and for talking to an insurer.
