When you live in Oklahoma, preparing for severe weather is just part of life. Tornadoes, high winds and unpredictable storms can strike with little warning, leaving families only minutes to find safety. For many homeowners, a storm shelter is the ultimate line of defense — a place where you can protect yourself and your loved ones when the skies turn dangerous.
But with so many storm shelter types, sizes and designs available, how do you know which one is right for your home? Choosing the right shelter goes beyond picking the first model you see. You’ll want to think about space, accessibility, installation location and long-term durability.
This guide will walk you through the most important factors to consider, the benefits of different styles and an overview of the underground concrete storm shelters that we offer so you can make an informed decision.

Why a Storm Shelter is Essential in Oklahoma
Oklahoma sits in the heart of tornado alley, where high-risk storms are a regular part of spring and summer weather patterns.
Even outside of peak tornado season, severe thunderstorms can produce damaging winds and hail strong enough to pose serious safety risks.
While in-home safe rooms and basements can provide some protection, an engineered storm shelter offers the highest level of safety in extreme conditions.
Built to withstand EF5-level winds, a properly installed storm shelter creates a secure environment for your family — regardless of the storm’s intensity.
Key Factors to Consider When Choosing a Storm Shelter
When selecting the best storm shelter for your home in Oklahoma, you’ll want to think about more than just cost. Here are some of the most important elements to weigh:
1. Size and Capacity
Consider how many people will be using the shelter. A smaller household might do fine with a compact unit, while larger families (or those who want to store emergency supplies) may need a bigger design.
2. Accessibility
In an emergency, quick access is crucial. A shelter with easy-entry stairs or a gentle slope can make a big difference — especially for older family members or anyone with mobility challenges.
3. Installation Location
Think about where your shelter will go — backyard, garage or another accessible outdoor spot. The location will impact how fast you can get inside during a storm.
4. Ventilation and Comfort
Good airflow is essential, especially if you expect to spend more than a few minutes inside. Consider models that include advanced ventilation systems for better comfort and safety.
5. Durability and Maintenance
In Oklahoma, your shelter should be able to handle decades of exposure to shifting soil and harsh weather conditions. Underground concrete storm shelters are especially durable, requiring minimal upkeep.

Above-Ground vs. Underground Shelters: Why Go Underground?
While some homeowners consider above-ground safe rooms, underground concrete shelters are often the preferred choice in Oklahoma for several reasons:
- Better Wind Resistance — Underground shelters are naturally shielded from high winds and flying debris.
- Temperature Stability — Being below ground keeps the shelter cooler in summer and warmer in winter.
- Less Visible — They blend into the landscape better than above-ground structures.
- Long Lifespan — With proper installation, they can last for decades with minimal upkeep.
Maintenance Tips for Your Storm Shelter
Once you’ve chosen your storm shelter, keeping it in top condition is essential.
Here are some maintenance tips for your storm shelter:
1. Inspect for Leaks — Check after heavy rains to make sure no water is seeping inside.
2. Test the Door Mechanism — Make sure it opens and closes smoothly.
3. Keep it Clean — Sweep out dirt, leaves and debris regularly.
4. Check Ventilation — Make sure the air vents are clear and unobstructed.
