HVHZ Material Requirements

All materials must meet Miami-Dade standards for hurricane construction

Roof Sheathing

Minimum 15/32" CDX plywood or 7/16" OSB. Must be rated for structural use.

APA Rated Sheathing

Hurricane Straps

Metal connectors rated for your uplift loads. Typically H2.5A or stronger for HVHZ.

1,500+ lb Uplift

Ring-Shank Nails

8d (2.5") for sheathing with deformed shank for better holding power.

Hot-Dipped Galvanized

Anchor Bolts

1/2" x 10" minimum, spaced per plans. Embedded in foundation.

6 ft Max Spacing

Hold-Downs

Heavy-duty connectors for shear walls. Sized based on calculated loads.

Per Engineering

Strap Nails

Special nails for hurricane connector installation. Follow connector specs.

Frequently Asked Questions

Common questions about HVHZ material takeoffs

How many hurricane straps do I need per roof truss?
Typically 2 straps per truss connection - one on each side connecting the truss to the top plate. For high-wind areas in HVHZ, you may need stronger straps or additional connectors. Check your approved plans for specific connector requirements. Some situations call for 4 connectors per truss.
How do I calculate roof sheathing for HVHZ?
Calculate roof area (length x width x 2 for gable roofs, adjusted for pitch), then divide by 32 sq ft per 4x8 sheet. Add 10-15% for waste and cuts. In HVHZ, use minimum 15/32 inch CDX plywood or 7/16 inch OSB with proper nail schedule. Our calculator above does this math automatically.
What fasteners are required for HVHZ construction?
HVHZ requires ring-shank or deformed shank nails for better holding power. Roof sheathing typically needs 8d (2.5 inch) nails at 4 inch edge / 6 inch field spacing (or 3/4 for high wind). Framing uses 16d nails. All fasteners should be hot-dipped galvanized for corrosion resistance.
How much waste should I add to my material estimate?
For sheathing, add 10-15% for cuts and waste. For fasteners, add 5-10%. Hurricane straps have minimal waste - order exact count plus a few spares. Better to have extra materials than to stop work waiting for a delivery. Return unused materials for credit.
