What Storms Have Hit Johnston Recently?

Johnston sits between Saylorville Lake and the rest of the metro, and spring and summer thunderstorms are common here. One inch (quarter size) is the size the National Weather Service uses for severe hail.

Severe reports (hail 1 inch or larger, wind 58 mph or stronger, wind damage and tornadoes) within about 6 miles of Johnston in the last 24 months, newest first. Source: National Weather Service Des Moines local storm reports via the Iowa Environmental Mesonet (Iowa State University). Report locations are approximate, and a street without a report can still have damage. Updated automatically; last checked November 3, 2026.

Johnston Homes and Hail: What the Numbers Say

Johnston has about 9,720 homes. The median home was built in 2004, and about 63% were built in 2000 or later. The median home value is $369,100.

That means many Johnston roofs are still the original builder-grade shingles, now around 20 years old. As shingles age they lose granules and flexibility, so a hailstorm that a new roof would shrug off can crack or bruise an older one. If your home is in one of the 2000s subdivisions and you have not had the roof checked since it was built, after the next severe storm is a good time to do it.

Many newer Johnston neighborhoods also have HOA rules for shingle color and style. Check your HOA guidelines before choosing a replacement; we will work within them.

How to Spot Hail Damage on a Johnston Roof

On the 2000s-era roofs common in Johnston, hail damage usually shows up as bruises and lost granules rather than holes. Here is what to look for, most of it safely from the ground:

• Dark, shiny spots where hail knocked the granules off. On 20-year-old shingles these can look like normal wear, which is why close-up photos matter.
• Granules piling up at the bottom of your downspouts after the storm.
• Dented vents, gutters, downspouts or AC fins. Soft metal shows hail hits clearly, and if it is dented the shingles were likely hit too.
• Chipped siding or torn window screens on the side of the house that faced the storm.

More photos and examples are in our hail damage roof repair guide.

What Our Johnston Inspection Includes

We start with drone photos of every slope, which matters on the two-story homes and steep roof lines in Johnston’s newer subdivisions. Then we photograph individual hail hits, check vents, gutters, siding and screens, and look in the attic if there are signs of a leak.

You get a written report with dated photos that explains what we found in plain words. The inspection is free, and if we find no storm damage, we will tell you that.

How Does a Hail Claim Work in Johnston?

You file the claim with your insurance company, and they send an adjuster to your Johnston home. We are not public adjusters, and your policy and your insurer decide what is covered.

If you think a recent storm damaged your roof, check your policy for its claim filing deadline. We never offer to pay, cover or waive a deductible.

Should I Repair or Replace My Johnston Roof After Hail?

A repair can work when only a few shingles are damaged, the roof is fairly young and matching shingles are still made.

Many Johnston roofs are original from the early 2000s, though, and patching a 20-year-old roof often means spending money on shingles near the end of their life. In that case a replacement, backed by the Owens Corning 50-year limited material warranty, the 25-year labor warranty through the Platinum Preferred program and our 10-year workmanship warranty, is usually the better value. We will show you the photos and both options.

Impact-Resistant Shingles for Johnston Homes

If your original roof needs replacing, it is a good time to consider impact-resistant shingles. They are rated under the UL 2218 test, with Class 4 the highest rating, and Owens Corning makes Class 4 lines that we install. No shingle is hail-proof, but they hold up better to severe hail like the 1-inch and larger reports in the table above.

Some insurance companies offer a discount for a Class 4 roof. Ask your insurer about any discount before you decide.

Johnston Hail & Storm Damage FAQ

How big does hail have to be to damage a roof in Johnston?

Damage depends on the hail size, wind and the age of your shingles. One-inch hail, the size the National Weather Service calls severe, can bruise or crack older shingles, and wind-driven hail does more harm. If a severe report shows up near Johnston in the table on this page and your roof is 15 years old or more, a free inspection is worth it.

How do I know if the latest storm damaged my Johnston roof?

Start with the storm table on this page. It updates automatically from National Weather Service reports and shows the most recent severe hail and wind near Johnston. A report nearby does not mean your roof was damaged, and damage can happen where nothing was reported, so a free inspection with drone photos is the only way to know.

I cannot see any damage from the ground. Should I still get an inspection?

Yes. Most hail damage is on the top of the shingles and cannot be seen from the yard. Dented gutters, vents or downspouts are a clue the roof was hit too. Our free inspection uses drone photos, so you can see the whole roof for yourself.

Can you be there when the adjuster inspects my Johnston home?

Yes, if you want us there. You still file and manage the claim with your insurer, and your policy decides what is covered.

My Johnston home was built in the 2000s. Is the original roof more likely to be damaged?

Often, yes. Original builder-grade shingles from the 2000s are now 15 to 25 years old. Older shingles are less flexible and have fewer granules, so they bruise and crack more easily in hail. An inspection will tell you where your roof stands.

My Johnston roof is about 20 years old. Is it worth repairing after hail?

Sometimes, if the damage is small and matching shingles are available. But a roof that age is near the end of its life, so a repair may only buy a few years. We will show you the photos and give you an honest comparison of repair and replacement.

Do you have recent jobs in Johnston?

Yes. Our crews check in on NearbyNow at every job, and the live map on this page shows our most recent work in Johnston. You can see more Johnston projects and reviews on our Johnston roofing and siding page.

Do Class 4 impact-resistant shingles stop hail damage?

They do not make a roof hail-proof, but Class 4 shingles hold up better to the hail sizes Johnston usually sees. Some insurers offer a discount for them, so ask your insurance company about any discount before you decide.

Does my HOA need to approve a new roof in Johnston?

Many Johnston neighborhoods have HOA rules for shingle color and style. Check your HOA guidelines or ask your HOA board before you choose a color. We will work within those rules.

How long does a roof replacement take in Johnston?

Most single-family roofs take one to two days once materials are delivered, depending on the size of the roof and the weather. We protect your landscaping and clean up nails and debris before we leave.
