Asbestos Sheets vs Steel Sheets : Which Roofing Material Should You Choose?
Asbestos Sheets vs Steel Sheets : Which Roofing Material Should You Choose?
When it comes to choosing the right roofing material, durability, safety, cost, and maintenance are key considerations. For decades, asbestos cement sheets were a preferred choice in the Indian market for their affordability and insulation capabilities. However, with growing awareness of health risks and evolving technology, steel sheets have gained prominence as a modern, high-performance alternative.
In this blog, we compare Asbestos Sheets and Steel Sheets on all essential parameters to help you make an informed decision.
Steel Sheets
Asbestos Sheets
Composition & Structure
Asbestos Sheets
- Made from cement reinforced with asbestos fibers
- Traditionally used for industrial, rural, and low-cost housing roofing
- Lightweight, insulating, and cost-effective
Steel Sheets
- Made from galvanized steel, sometimes coated with zinc or aluminum (e.g., GI or Galvalume)
- Available in various profiles, thicknesses, and coatings
- Modern and premium roofing option
Durability & Lifespan
Asbestos Sheets
- Typically last 20–25 years
- Prone to breakage on impact
- Susceptible to moss growth and weather-induced wear
Steel Sheets
- Lifespan ranges from 30–50 years depending on coating and maintenance
- Strong impact resistance
- Withstands heavy rains, heat, and wind
Health & Safety
Asbestos Sheets
- Asbestos is a known carcinogen - dangerous when fibers are released during damage or cutting
- Banned or regulated in many countries due to health risks
- Should be handled with caution; not eco-friendly
Steel Sheets
- Safe, non-toxic, and recyclable
- Fire-resistant and mold-resistant
- A safer and sustainable choice for families and commercial setups
Thermal & Sound Insulation
Asbestos Sheets
- Good natural insulation against heat
- Moderately effective in reducing external noise
Steel Sheets
- Tends to heat up faster under direct sun
- Requires insulation backing for better performance
- Can be noisy during rains unless treated
Cost Comparison
Asbestos Sheets
- Inexpensive and widely used in rural areas
- Lower upfront cost, but higher long-term risk (health/environmental)
Steel Sheets
- Higher upfront cost
- Long-term savings on maintenance and repairs
- Better ROI for modern construction
Applications
| Application Area | Asbestos Sheets | Steel Sheets |
|---|---|---|
| Industrial Sheds | ✅ Yes | ✅ Yes |
| Residential Homes | ❌ Not Recommended | ✅ Yes |
| Farmhouses/Rural Homes | ✅ Yes | ✅ Yes |
| Commercial Buildings | ❌ Limited Usage | ✅ Yes |
| High Rainfall Areas | ❌ Prone to Leaks | ✅ Excellent Performance |
Which One Should You Choose?
If you are building a low-cost shed or rural housing with a limited budget, asbestos sheets may still be in use. However, due to increasing regulation and safety concerns, they’re being phased out.
For urban residential, commercial, or industrial use, steel sheets are the smarter long-term investment. They offer better safety, modern aesthetics, eco-friendliness, and durability.
Pro Tip: For better thermal comfort with steel roofing, pair it with a PUF panel, insulation layer, or ventilated roofing systems.
