Aluminium vs Steel Roofing: Cost, Durability & Eco Impact Comparison (2025)
Published by: ALUTimes | Updated on: July 7, 2025
Introduction
As India accelerates construction in smart cities, green buildings, and industrial expansion, choosing the right roofing material is crucial. The battle between aluminium vs steel roofing has intensified in 2025. Builders, contractors, and architects now prioritize not just cost, but also longevity, energy efficiency, and environmental impact. This in-depth comparison will help you decide the best fit for your project.
Why This Topic Matters in 2025
- Green building certifications now require lightweight, recyclable roofing options.
- Solar energy adoption demands roof compatibility with PV installations.
- Corrosion resistance is a major concern due to urban pollution and coastal expansion.
- Material costs have shifted due to global metal price fluctuations and local sourcing incentives.
Basic Properties: Aluminium vs Steel
| Property | Aluminium Roofing | Steel Roofing |
|---|---|---|
| Weight | Lightweight (2.7 g/cm³) | Heavier (7.85 g/cm³) |
| Corrosion Resistance | High (Naturally resistant) | Needs galvanization or coating |
| Thermal Efficiency | Reflective, reduces heat absorption | Moderate, requires insulation |
| Installation | Easy, due to lightness | Requires stronger support structure |
| Recyclability | 100% | 100% |
Cost Comparison (2025)
Here’s the average cost range per square foot in India:
- Aluminium Roofing: ₹350 – ₹550 per sq.ft (premium grades like 5052-H32 costlier)
- Steel Roofing (GI/PPGI): ₹200 – ₹400 per sq.ft (depends on gauge & coating)
Although aluminium roofing has a higher upfront cost, it reduces lifetime maintenance expenses, especially in coastal or industrial zones.
Durability & Maintenance
Aluminium: Naturally forms an oxide layer, preventing rust. Can last over 40–50 years with minimal maintenance.
Steel: Requires coating (like zinc, galvalume) to prevent rust. In harsh climates, coatings may erode over time. Lifespan: 20–35 years.
Environmental Impact
Aluminium is a green metal. It’s 100% recyclable and consumes only 5% of the energy during recycling compared to primary production. It’s often the first choice in LEED & IGBC certified buildings.
Steel is recyclable too, but energy-intensive to produce and coat. Galvanized steel creates hazardous by-products if not processed correctly.
Roofing Applications
- Aluminium: Villas, high-end residential, commercial complexes, coastal regions, solar-ready buildings
- Steel: Warehouses, factories, rural housing, large sheds where cost is priority
Solar Panel Compatibility
Aluminium is ideal for solar panel installations due to its high reflectivity and minimal heat absorption, which helps keep panel performance optimal. It’s also compatible with most aluminium racking systems.
Steel roofing needs insulation to avoid overheating under panels, especially in tropical areas.
Noise, Aesthetics & Customization
Aluminium: Quieter during rain, comes in multiple color-coated sheets, modern appearance
Steel: Louder during rain/hail, available in fewer aesthetic variants
Which Roofing Material Should You Choose?
- Choose Aluminium: If your project is in coastal or high-humidity zones, if you want a lightweight, long-lasting roof with green certifications.
- Choose Steel: For budget-sensitive industrial or temporary structures where aesthetics and lifespan are not top priority.
