An experienced company can confirm the cause with a quick inspection.

What Local Wind And Debris Rules Mean For Window Projects

It is usually about wind load, opening protection, and whether the home sits in a wind-borne debris region that changes what is allowed on the building envelope.

Even when a property is not treated as a high-velocity hurricane zone, the surrounding risk still pushes the project toward impact-rated or otherwise code-compliant assemblies.
