Everything Roofers, Architects, and Permitting Officials Need to Know

When it comes to roofing in Florida, few topics are more important—or more misunderstood—than wind uplift testing and calculations. With hurricanes, tropical storms, and daily high-wind events, roofs in Florida must meet stringent building codes. For metal roofing, this means more than just selecting a strong panel. It requires tested assemblies, proper fastening patterns, and accurate uplift calculations that comply with Florida Product Approval and Miami-Dade NOA standards.

At Gulf Coast Supply & Manufacturing, we’ve been at the forefront of wind uplift engineering for over 30 years. In this article (with two embedded videos—a condensed version and a full in-depth version), you’ll learn how to calculate wind uplift, why it matters, and how inspectors, contractors, and homeowners alike can ensure roofs meet or exceed code.

What is Wind Uplift?

Wind uplift is the force of wind creating suction that literally tries to lift a roof off the structure. The stronger the wind and the closer you are to Florida’s coastline, the greater the forces at play.

Florida Building Code requires that roofing assemblies meet specific uplift pressures through testing and engineering documentation. These requirements vary by exposure category, building height, and location within the state.


Key Takeaways from Our Video Training

We’ve created two video resources for you:

  • Condensed 3-Minute Version: A quick overview for roofers, inspectors, and homeowners who want the essentials.
  • Full 15-Minute Training: A deep dive into calculation methods, pressures, and engineering behind uplift requirements.

Watch both versions below:

Video Summary

In these videos, Jared Pearce from Gulf Coast Supply walks through:

  • The basics of wind uplift forces and why they are critical.
  • Step-by-step process of calculating pressures based on building specs.
  • How to apply Florida Product Approval and Miami-Dade NOA standards.
  • Examples of real calculations from Gulf Coast projects.
  • Tools and resources roofers can use to avoid failed inspections.

By the end, you’ll understand not just the math, but the why behind uplift requirements.


Why Wind Uplift Matters in Florida

  • Hurricane Zone: Florida roofs must withstand Category 4–5 winds.
  • Permitting & Inspection: Incorrect uplift design = failed inspections, costly delays.
  • Liability: Contractors who cut corners risk lawsuits, code violations, and unhappy customers.
  • Resale Value: Homeowners and developers want roofs backed by proper engineering.
