ROOFING
Asphalt shingles dominate the North American residential market —they're cheap and familiar. But for importers, developers, and anyone thinking long-term, stone coated metal roof tiles tell a very different story. Let's compare the numbers honestly.
| Factor | Asphalt Shingles | Stone Coated Steel |
|---|---|---|
| Weight | 10-15 kg/m² | 6-7 kg/m² |
| Lifespan | 15-20 years | 50+ years |
| Fire Rating | Class A (fiberglass) Class C (organic) | Class A —non-combustible |
| Wind Resistance | 60-130 mph (depends on install) | 120+ mph (193 km/h) |
| Hail Resistance | Class 1-3 impact | Class 4 —highest rating |
| Maintenance (50yr) | Replace 2-3脳 | Near-zero |
| Recyclable | 11 million tons/yr to landfill (US alone) | 100% recyclable steel |
Asphalt shingles cost $3-5/m² for materials —undeniably cheap upfront. Stone coated steel runs $8-15/m². But roofing isn't a one-time purchase. Here's the real math for a 200m² roof over 50 years:
| Cost Over 50 Years | Asphalt Shingles | Stone Coated Steel |
|---|---|---|
| Installations needed | 3 (every 17 years) | 1 |
| Material cost (200m²) | $1,800-3,000 脳 3 | $1,600-3,000 脳 1 |
| Labor (3 installs) | $3,000-5,000 脳 3 | $1,200-2,000 脳 1 |
| Tear-off & disposal (2脳) | $2,000-4,000 | $0 |
| 50-Year Total | $10,400-22,000 | $2,800-5,000 |
* Conservative estimates. Actual costs vary by region and labor rates. Assumes 200m² roof, mid-range products.
1. Lifetime value. Stone coated steel costs 3-4脳 less over 50 years when you factor in replacements.
2. Insurance savings. Class 4 hail rating and Class A fire rating often qualify for significant insurance premium discounts —ask your insurer.
3. No landfill guilt. The US discards 11 million tons of asphalt shingles annually. Steel recycles forever without degradation.
4. Tropical climate ready. In humid regions (Southeast Asia, Africa, Caribbean), asphalt shingles absorb moisture, grow moss, and curl at edges within 8-12 years. Stone coated steel with Alu-zinc coating resists corrosion for decades.
If you're flipping a house for quick resale, asphalt is fine. If the budget is extremely tight and you need a roof now, asphalt gets the job done. But for any project where you plan to own the building longer than 15 years —or you're an importer supplying developers —stone coated steel is the economically rational choice.
