Common Questions

Click to expand answers

When should I get wind load calculations for hurricane season? +

Get your wind load calculations 2-3 months before hurricane season starts (June 1). This gives you time to order materials with the right ratings and avoid the pre-storm rush when everyone needs calculations at once.

What happens if I wait until a storm is approaching? +

Engineers get overwhelmed with emergency requests. Turnaround times go from 24 hours to 2+ weeks. Supply chains for rated products get strained. Prices go up. Permits take longer to process.

What wind speed should I prepare for in Miami-Dade? +

Miami-Dade County is in the High Velocity Hurricane Zone (HVHZ) with design wind speeds of 170-180 mph per ASCE 7-22. This is one of the highest wind speed requirements in the United States.

Do I need NOA numbers for all products? +

In Miami-Dade HVHZ, yes. Products must have a valid Notice of Acceptance (NOA) from Miami-Dade County showing they meet the high velocity hurricane zone requirements. Regular Florida Product Approvals are not enough.
