Storms are how most Des Moines roofs actually end.

Hail frequency in the Des Moines metro runs well above the US average, and claim rates reflect it. A meaningful fraction of homeowners here will file a wind or hail claim during any given roof's service life. Knowing what to look for, when to involve insurance, and what simple maintenance extends the roof between events is how you get twenty-five years out of a roof that nationally averages twenty.

Section onePost-storm self-inspection, from the ground

After any storm with hail larger than a quarter or winds above roughly 55 mph, do a ground-level walk of the house. Look for granule piles at downspout outlets (the roof shed its protective layer), dents in gutters or window screens, splatter marks on horizontal deck boards or AC condensers (those correlate well with roof-surface hail strikes), and any obvious missing or lifted shingles. If you see any of those, a professional inspection is warranted — but you do not need to climb the roof yourself.

Section twoWhen to file, when not to

Iowa homeowners policies vary, but most have a windstorm/hail deductible that's higher than the all-perils deductible, and some have percentage deductibles (1 or 2 percent of dwelling coverage). For minor cosmetic damage — a few dings, no leaks, no missing shingles — filing may not make financial sense once you compare likely payout against deductible and future premium impact. For substantial damage, filing promptly matters — most policies give you a limited window (often one year) from the date of loss.

Section threeThe storm-chaser warning

Within 72 hours of any significant Iowa storm event, out-of-state contractors descend on affected neighborhoods. They knock, offer free inspections, "find" damage, and pressure a same-day signature on an "contingency agreement" that ties you to them if insurance approves. Several have left Iowa homeowners with half-done roofs after failing to pass final city inspection. Never sign anything during a door-knock visit. Always vet a post-storm contractor through BBB, Secretary of State business registration, and local references.

Section fourAnnual maintenance that's worth doing

Once or twice a year, have the gutters cleared; clogged gutters back water under the shingles at the eave. Every two to three years, have a roofer do a top-to-bottom inspection of flashings, pipe boots (the rubber gaskets around vent pipes crack reliably after 10 to 15 Iowa summers), and sealant at chimneys. Trim any tree limbs within six feet of the roof — squirrels, abrasion, and shade-induced moss growth all shorten shingle life.

Section fiveSnow, ice dams, and attic ventilation

Ice dams form when heat escapes into the attic, melts snow above, and re-freezes at the cold eave. The resulting ice backs up under the shingles and leaks into walls. The fix is rarely at the roof surface — it's attic insulation and ventilation. Any Des Moines roofer doing a replacement should check baffle airflow from soffit to ridge and flag inadequate insulation. Ridge vent plus clear soffit intake is the standard solution.
