How this estimate works

These are ballpark planning figures, not a quote. They assume:

HVHZ-compliant dock-high doors (impact-rated, reinforced track and hardware) run about $3,500 to $5,500 installed, each.
HVHZ-compliant drive-in or grade-level doors run about $4,500 to $7,500 installed, each, since they are larger and typically need a heavier impact-rated panel.
HVHZ-compliant roof replacement (TPO or modified bitumen systems rated for the wind uplift and impact requirements in Miami-Dade and Broward) runs about $8 to $12 per square foot, materials and labor.
These ranges are generic planning figures, not a price for any specific product, building, or contractor. Actual cost depends on door size, wind zone within HVHZ, roof deck condition, permitting, and current material pricing.
