Understanding Windstorm Inspections In Texas

Expert Windstorm Engineering Design Services and Inspections for the State of Texas

When it comes to safeguarding your property in the face of Texas storms, knowledge is your best ally. At JRH Engineering & Environmental Services, Inc. (JRH), we understand the importance of you staying informed and prepared. That's why we've put together this comprehensive blog post to guide you through the intricate world of windstorm inspections in the Lone Star State of Texas.

Understanding Windstorm Inspections

What is a Windstorm Inspection?

A Windstorm Inspection is a critical evaluation of your property's ability to withstand the fierce winds that often accompany Texas storms. These inspections are essential for determining whether your property meets the stringent construction standards set forth by the Texas Department of Insurance (TDI). Contact JRH to determine if your project requires an inspection or visit TDI’s website for a list of of projects that do not require an inspection

Does JRH Engineering Conduct Windstorm Inspections?

Yes! Windstorm inspections in Texas are conducted by JRH who is well-versed in the state's building codes and windstorm-resistant construction requirements.

JRH provides Windstorm Engineering Design Services for structural projects for new construction or to modify existing structures to comply with jurisdictional regulations.

When and How Inspections Are Performed

When is the Inspection Performed?

When it comes to the timing of windstorm inspections, there are crucial considerations:

  • JRH inspectors perform inspections during, not before or after, the construction or repair process. They must witness the work in progress to ensure compliance.

  • A JRH-licensed professional engineer may perform inspections after construction is complete, known as post-construction inspections. However, conducting an inspection during construction is often less invasive and can be more cost-effective.

Does JRH Inspect Our Structure Before We Start Work?

No, JRH inspectors only perform inspections while the work is in progress. However, they are available to meet or discuss any planned work to educate and inform all parties about compliance requirements.

What if the Work was Completed Without an Inspection?

If a new structure, addition to an existing structure, alteration, repair, or re-roof was completed without an inspection, then a JRH licensed professional engineer must perform an inspection. This is known as a post-construction inspection, which ensures that the structure meets windstorm-resistant construction standards.

Building Codes and More

Questions about Building Codes

Are Commercial Structures Required to Follow TDI Construction Guidelines?

Yes, commercial structures must adhere to TDI’s adopted building standards if they are to be insured for wind and hail coverage through the Texas Windstorm Inspection Association (TWIA). As a minimum requirement, the structure must be built in accordance with TDI’s adopted building standards.

What is the Texas Windstorm Insurance Association (TWIA)?

The Texas Windstorm Insurance Association (TWIA) is a not-for-profit organization that provides windstorm and hail insurance to Texas residents who can't get coverage in the private market.

TWIA was established in 1971 by the Texas Legislature to provide coverage to those who can't get insurance from the voluntary insurance market.

TWIA policies only cover property damage caused by wind and hail. They don't cover damage caused by flooding or storm surges.

TWIA policies are available to home and commercial property owners in the coastal counties of Texas. Windstorm insurance isn't required by law in Texas. However, if you live near the coast and have a mortgage, your lender will likely require you to have windstorm coverage.

You can talk to your insurance agent to learn about all of your options.

How Can I Obtain Copies of the International Building Code (IBC) and the International Residential Code (IRC)?

You can purchase these codes from the International Code Council (ICC) at

Can I Get a Listing of Approved Windows, Doors, and Other Products That JRH Engineering & Environmental Services, Inc. Reviewed?

Yes, you can access product evaluations by contacting JRH.

Understanding Roof Terminology

What is a "Roof Pitch"?

The roof pitch indicates the incline of the roof as a ratio of vertical rise to the open span (twice the horizontal run). It is expressed as a fraction. For example, if the total roof rise is 4 feet and the total span is 24 feet, the pitch is 4/24=1/6.

What is "Roof Slope"?

Roof slope is the incline of the roof as a ratio of the vertical rise to the horizontal run. For example, a roof that rises at a rate of 4 inches for each foot of horizontal run is said to have a 4 in 12 (4:12) slope.


Navigating the Windstorm Inspection Procedures in Texas may seem complex, but with the right information and preparation, it becomes a manageable process. Ensuring your property complies with windstorm-resistant construction standards not only provides economic benefits but also safeguards lives and property during severe weather events.
