Which roofing attachment method is specifically required in Hawaii's hurricane zones for asphalt shingles on residential construction?
Correct Answer
C) 6 nails per shingle with corrosion-resistant fasteners
Hawaii requires 6 nails per shingle with corrosion-resistant fasteners in hurricane zones to meet enhanced wind uplift requirements and resist salt air corrosion.
Why This Is the Correct Answer
Hawaii's hurricane zones require 6 nails per shingle with corrosion-resistant fasteners for asphalt shingles on residential construction. This enhanced fastening pattern provides superior wind uplift resistance necessary for hurricane-force winds. The corrosion-resistant requirement addresses Hawaii's salt air environment which rapidly degrades standard fasteners. This specification exceeds standard roofing practices to meet the extreme weather conditions and coastal environment unique to Hawaii's hurricane-prone areas.
Why the Other Options Are Wrong
Option A: Staples with minimum 1-inch crown width
Staples with 1-inch crown width are insufficient for Hawaii's hurricane zones. While staples may be acceptable in some standard applications, they don't provide the holding power needed for extreme wind conditions. The crown width specification doesn't address the critical need for increased fastener quantity and corrosion resistance required in Hawaii's coastal hurricane environment.
Option B: Adhesive strips with mechanical fasteners as backup
Adhesive strips with mechanical fasteners as backup don't meet Hawaii's specific hurricane zone requirements. While adhesive can supplement attachment, it's not reliable as a primary method in extreme weather. Hawaii specifically mandates 6 nails per shingle, not a combination system. Adhesives can fail in high heat and humidity conditions common in tropical climates.
Option D: 4 nails per shingle, hand-driven only
Four nails per shingle is insufficient for Hawaii's hurricane zones, even if hand-driven. Standard residential construction typically uses 4 nails, but Hawaii's enhanced wind requirements mandate 6 nails per shingle. Hand-driving doesn't address the quantity deficiency or the critical need for corrosion-resistant fasteners in the salt air environment.
Memory Technique
Remember 'Hawaii SIX-pack': 6 nails per shingle for Hawaii's hurricane zones, plus corrosion-resistant fasteners for the salty Pacific environment.
