Did Hail Damage Your Siding, Gutters, or Windows? What Iowa Homeowners Should Check

It may have. Hail that can bruise a roof can also crack vinyl siding, chip fiber cement, dent gutters and downspouts, and tear screens or crack window glass. After any storm with hail the size of a quarter or larger, walk around your home, photograph what you see from the ground, and get a registered contractor to inspect before you decide the damage is only cosmetic.

Most homeowners look up at the roof and stop there. That’s understandable, but walls, gutters, and windows take hits from a different angle. Homeowners who call Heartland Roofing, Siding & Solar after a storm often say the siding took most of the hit, or that they never got on a ladder to check the gutters.

Below are the questions Iowa homeowners ask most about hail damage beyond the roof, from spotting it to choosing who fixes it. For the roof itself, read our guide to what insurers check on a hail damaged roof.

Spotting Hail Damage on Your Siding

How do I know if hail damaged my vinyl siding?

Look for cracks, punctures, and small holes, especially on the side of your home that faced the storm. Vinyl tends to get more brittle as it ages and in cooler weather, so older panels can crack from hail that newer siding might shrug off. Check low areas and behind shrubs too.

Hold a flashlight flat against the wall and cracks become much easier to see. Photograph each spot with a coin for scale. Small holes still matter in Iowa, because water that gets behind vinyl can soak the sheathing, the wood layer under your siding, and stay trapped through winter. If panels need replacing, our siding services page explains your material options.

What does hail damage look like on fiber cement or engineered wood siding?

On fiber cement, look for chips, cracked corners, and spots where the paint is knocked off to show the gray board underneath. On engineered wood, such as LP SmartSide, look for dents that break the paint film or expose the wood strand core. Either one can let moisture in if it’s left unsealed.

These boards are thicker than vinyl, but they aren’t hail proof. Damaged spots need to be sealed and painted, or the board replaced, before winter. A chip that looks minor in October can take on water, freeze, and widen by spring. Photograph damage close up and from a few steps back so the pattern across the wall is clear.

How big does hail have to be to damage siding?

There’s no single cutoff, but the National Weather Service classifies hail one inch in diameter or larger, roughly the size of a quarter, as severe. Wind matters too. Hail driven sideways by strong wind hits siding and windows hard, so one side can look fine while another is battered.

Note the date of the storm and the hail size reported for your area. Then inspect the walls that faced the wind first. Smaller hail can still crack older, sun weakened vinyl, so don’t rule out damage just because the reports sounded small. A contractor can compare the damage pattern to the storm date for your claim.

Gutters, Downspouts, and Windows

My gutters are dented but still drain. Is that real damage?

It can be. Dents in aluminum gutters and downspouts are one of the clearest signs of hail, and adjusters often check them as evidence. Whether dents count as covered damage depends on your policy, since some policies exclude damage considered purely cosmetic, like dents that don’t affect function.

Dent size also helps show how big the stones were. Beyond the dents, check for seams pulled apart, hangers knocked loose, and downspouts crushed so they drain slowly. A crushed downspout matters in Iowa because water can back up and spill next to your foundation instead of draining away from it. Our gutter services page covers repair and replacement options.

What does hail damage to windows look like?

Check for cracked or broken glass, torn or punctured screens, dented aluminum wraps, and cracked vinyl frames or sills. Window wraps are the bent metal trim covering the wood around the outside of a window, and they dent easily. Note every damaged window, even when the glass itself is fine.

If glass is broken, cover the opening right away. The Iowa Insurance Division advises homeowners to cover broken windows to prevent more damage and to save receipts for tarps and supplies so they may be reimbursed later. Torn screens are usually a simple fix, but include them in your photos because they help document the storm.

My house was built before 1978. Does that change window replacement?

Yes. Iowa requires at least one certified lead safe renovator on renovations that disturb painted surfaces in housing built before 1978, other than minor repairs, and window replacement never qualifies as a minor repair. Before work starts, you should receive the state pamphlet Lead Poisoning: How to Protect Iowa Families.

Many older homes in Des Moines, Ames, and Iowa City neighborhoods still have original painted trim around their windows. Lead safe work means containing dust with plastic, cleaning carefully, and keeping debris out of your living space. Ask every contractor bidding your hail repair to show their certification before you sign. Our window replacement page covers the options we install.

Insurance and Your Claim

Will homeowners insurance cover hail damage to my siding and gutters?

Most policies cover sudden hail damage, but what gets paid depends on your policy, your deductible, and whether the damage is considered functional or cosmetic. Some policies carry a separate wind and hail deductible. Call your agent, ask how your policy treats siding and gutters, and file promptly once damage looks larger than your deductible.

Hail claims are common. Insurance Information Institute data from ISO shows that nationally, wind and hail averaged 2.80 claims per 100 insured homes per year from 2019 to 2023, nearly twice the rate for water damage and freezing. Policies can also set claim filing deadlines, so don’t wait until spring. Our guide to roof insurance claims in Iowa walks through adjuster visits and payouts.

Can a contractor pay or waive my insurance deductible?

No. Under Iowa Code section 103A.71, a residential contractor can’t advertise or promise to rebate any part of your insurance deductible, including through a discount or allowance. A contract that breaks this rule is void. If someone offers to cover your deductible, treat it as a red flag and keep looking.

The same law requires a written Notice of Contract Obligations and Rights, signed before or when you sign the contract, explaining that you may owe the contractor for the work even if insurance doesn’t pay. Read it carefully before you sign. Your deductible is your share of the claim, and a contractor who offers to absorb it makes the contract void under Iowa law.

Choosing Who Fixes It

Should I sign with the contractor who knocked on my door after the storm?

The Iowa Attorney General notes that legitimate contractors rarely go door to door, and Iowa’s door to door sales law usually gives you three business days to cancel a contract signed at your home. The Iowa Insurance Division suggests getting estimates from at least two registered contractors.

Check registration in the state’s online database. Iowa requires contractors who earn $2,000 or more a year from construction to register, and most contractors based outside Iowa must post a $25,000 bond. Ask where their nearest office is and how long they’ve worked in Iowa. Storm chasers often leave before warranty problems show up.

What warranty should I expect on hail repair work?

Ask for the labor warranty in writing before you sign, separate from the manufacturer’s product warranty. A product warranty covers defects in the siding, gutters, or windows themselves. A labor or workmanship warranty covers how they were installed, which matters most if a rushed storm job goes wrong later.

For reference, Heartland backs every full replacement of roofing, siding, or gutters with a 10 year labor and workmanship warranty. Whoever you hire, confirm which warranty applies to your scope, since replacing a few damaged panels is a repair, not a full replacement.
