Every business owner in Cleveland County knows the date, even if they weren’t here for it: May 20, 2013. The National Weather Service in Norman rated the tornado an EF-5 — the top of the scale — as it struck the Newcastle, south OKC, and Moore areas in McClain and Cleveland Counties. Per the NWS storm survey, it carved a path length of approximately 14 miles, stayed on the ground approximately 40 minutes, and reached a preliminary maximum path width of 1.1 miles. Twenty-four people were killed and 212 injured, and over 300 homes experienced EF-4/EF-5 damage along the tornado path.

The homes made the national news. But along that same 14 miles sat businesses — shops, offices, medical practices, restaurants — and their owners spent the next months and years learning, the hard way, exactly what their commercial property policies did and didn’t do.

We’ve been insuring businesses in Norman and the OKC metro since 1997, which means we lived through 2013 with our clients. These are the lessons that still hold — because this risk hasn’t gone anywhere. NWS Norman’s county tornado data shows Cleveland County has recorded 111 tornadoes from 1950 through 2025, ranked 5th among Oklahoma counties. And 2024 set the state’s all-time record with 152 tornadoes, the highest annual total on record since 1950. This is a current exposure, not a history lesson.

Lesson 1: The building limit has to survive a disaster economy

Most commercial property policies pay based on replacement cost — what it takes to rebuild. Here’s what 2013 taught: rebuilding after a widespread disaster doesn’t happen at normal prices. When hundreds of structures need contractors, lumber, and roofers at once, demand outruns supply and costs climb precisely when you need every dollar of your limit.

The practical moves:

  • Set your building limit to a realistic current rebuild cost, not the purchase price, not the tax valuation, not the loan balance. Construction costs in the OKC metro have moved substantially in the last decade; a limit set years ago is almost certainly stale.
  • Understand your co-insurance clause. Most policies require you to insure to a stated percentage of value (often 80–90%). Fall short, and the carrier reduces every claim payment proportionally — even small ones. Our archive posts on co-insurance in Oklahoma commercial property and avoiding underinsurance penalties walk through the math.
  • Ask about ordinance or law coverage. If your building is older, current building codes may require upgrades during reconstruction that a standard policy won’t pay for. After a total loss, you rebuild to today’s code, not 1985’s.

Lesson 2: The check for the building isn’t the whole loss

Ask any owner who went through it: the building was only half the problem. The other half was the months of zero revenue while they rebuilt — with payroll, loan payments, and taxes still due.

That’s what business interruption coverage (also called business income coverage) exists for. It replaces the income your business loses during a covered shutdown and pays the continuing expenses that don’t stop just because the doors are closed. Add extra expense coverage, and the policy also funds the costs of getting back up and running fast — temporary space, rented equipment, moving costs.

Three details matter enormously here:

  1. The period of restoration. Coverage runs until the property is (or reasonably should be) restored. After a major tornado, when every contractor in the metro is booked, restoration takes longer than anyone expects. Make sure your limits and time frames reflect a disaster-market timeline, not a normal one.
  2. Extended business income. Reopening day is not back-to-normal day. Customers drift back slowly. Extended business income coverage continues payments for a period after reopening while revenue recovers.
  3. Realistic worksheets. Business income limits should come from your actual financials, not a guess. We’d rather spend twenty minutes with your P&L than watch a client discover mid-claim that their limit covers ninety days of a nine-month closure.

Our archive piece Business Interruption Insurance: Real-Life Examples in Oklahoma shows how this plays out in practice.

Lesson 3: Know your wind/hail deductible before the storm does

Oklahoma commercial policies commonly carry a separate wind/hail deductible, often expressed as a percentage of the building limit rather than a flat dollar amount. On a $2 million building, a 2% wind/hail deductible is $40,000 out of pocket — a very different conversation than a $5,000 flat deductible, and one you want to have at renewal, not at the claims desk.

There’s no universally right answer; a higher percentage deductible buys real premium savings, and for some businesses that trade makes sense. The failure mode isn’t choosing a percentage deductible — it’s not knowing you have one.

Lesson 4: Preparation is a coverage multiplier

The businesses that recovered fastest in 2013 had three boring things in place: current photo/video documentation of their premises and contents, copies of key records stored off-site or in the cloud, and a one-page plan for who calls whom after a loss. None of that costs money. All of it speeds up a claim. Keep our archive checklist What to Do Immediately After Storm Damage in Oklahoma bookmarked — it applies to commercial losses as much as homes.

The annual review that Moore made non-negotiable

Here’s the discipline we recommend to every commercial client, ideally each spring before storm season peaks:

  • Re-check building and contents limits against current rebuild and replacement costs.
  • Confirm you’re clear of any co-insurance penalty.
  • Review business income limits against your latest financials.
  • Confirm your wind/hail deductible and what it means in dollars.
  • Ask whether ordinance/law and extended business income are on the policy.

That’s a thirty-minute conversation once a year. May 20, 2013 is why we insist on it.

Let us stress-test your policy — the zero-hassle way

You don’t need to become a policy expert; that’s our job.
