Choosing between metal and asphalt shingles is Jamaica's most common roofing dilemma. With 15 years of installation data across all 14 parishes, Weathershield Limited reveals which material outperforms tropical heat, hurricane winds, and long-term value.
Material Science BreakdownModern Metal Roofing: 26-gauge Galvalume® steel with Kynar 500® finish resists fading and corrosion. Stone-chip coatings provide impact resistance against hail and flying debris.
Advanced Asphalt Shingles: Fiberglass mats with algae-fighting copper granules and rubber-modified flexibility for heat expansion.
Performance Comparison| Factor | Metal Roofing | Asphalt Shingles |
|---|---|---|
| Heat Resistance | Reflects 85% solar radiation | Absorbs heat |
| Wind Rating | 180mph (UWI Mona tested) | 130mph (with adhesives) |
| Salt Corrosion | 40-year coastal warranty | Granule loss in 7-10 yrs |
| Lifespan | 50+ years | 15-25 years |
- Choose Metal If: Within 5 miles of coast, planning solar installation, or prioritizing longevity
- Choose Shingles If: In cooler elevated parishes, have complex roof architecture, or need phased installation due to budget
- Metal Roof: J$2.55 million total (including maintenance)
- Shingle Roofing: J$3.77 million (including replacement at year 15) While shingles save 35% upfront, metal provides 48% long-term savings in Jamaica's climate.
200+ installations shows:
- Metal roofs maintain 95% reflectivity after 10 years in coastal environments
- Shingle roofs in humid require 40% more maintenance
- Metal roofs reduced attic temperatures by 20°F versus shingles during heatwaves
