Hawaii's Unique Roofing Challenges
Hawaii's island climate destroys standard roofing materials faster than anywhere in the mainland US:
- Salt air: Corrodes metal, degrades adhesives, rusts nails
- Trade winds: 12-15 mph constant, gusts to 40+ mph
- Intense UV: Year-round sun accelerates material breakdown
- Heavy rain: 17-50 inches/year depending on location

Lifespan: 30-40 years · Cost: $20-30/sq ft · Wind rating: 130+ mph
Pros: Generates electricity, pays for itself in 5-7 years in Hawaii, modern look.
Cons: Highest upfront cost, longer installation, requires solar expertise.
Best for: Hawaii's highest electricity costs ($0.35/kWh). ROI is excellent here.
Lifespan: 12-15 years · Cost: $4-6/sq ft · Wind rating: 110+ mph
Pros: Cheapest upfront, fast installation, easy repairs.
Cons: Degrades 40% faster in Hawaii, poor wind resistance, frequent repairs needed.

Our Recommendation
For most Hawaii homeowners: Standing seam metal roofing offers the best value. Higher upfront cost, but lasts 2-3x longer than shingles and requires minimal maintenance in salt air.
If budget allows and you're staying long-term: Solar roof tiles make financial sense given Hawaii's electricity costs.
