Features Of Stone Coated Steel Roofing
What is stone-coated steel roofing?
Stone-coated steel roofing is a high-performance roofing system made from alloy of Aluminium & Zinc (GL) steel panels coated with stone chips. It combines the strength of metal with the appearance of tiles or shingles, offering long-lasting protection and style.
Is stone-coated steel roofing suitable for Indian weather?
Yes. It is ideal for India’s diverse climate—resistant to heavy rain, high heat, humidity, and strong winds. It also performs well in coastal areas due to its corrosion resistance.
Will it keep my home cooler during hot summers?
Absolutely. The stone coating on the roofing sheets being a bad conductor of heat reduces transmission beneath. The sheet also allows for air circulation beneath the panels, helping to reduce indoor temperatures and lower energy costs, especially in peak summer months.
Can it withstand heavy rainfall and monsoons & strong winds?
Yes. The interlocking design and water-resistant coating makes it highly leak-proof and reliable during intense monsoon rains.
It can resist wind speeds up to 120km/h making it suitable for cyclone prone regions like Odisha & West Bengal.
Is it noisy during rain or hailstorms?
No. Despite being a metal product, the stone coating and underlayment reduce noise, making it quiet and comfortable even during heavy rain when compared with a standard GI sheet.
Is it resistant to rust and corrosion?
Yes. The steel is coated with zinc-aluminum (Galvalume AZ 150 GSM) and a stone layer, making it highly resistant to rust, especially in humid and coastal areas like Kerala, Chennai, or Goa.
How long will it last?
Stone-coated steel roofs come with a lifetime limited warranty of 25 years, with very little maintenance. It’s one of the most durable roofing options available in India.
Is it fire resistant?
Yes. It is non-combustible and offers excellent fire resistance—ideal for areas with dry seasons or risk of fire.
Is it expensive compared to traditional Indian roofing materials?
While the initial cost is higher than clay tiles or asbestos sheets, it offers better durability, appearance, and energy savings, making it more cost-effective in the long run.
How environment friendly is this?
Steel being one of the most sustainable products mainly because of its recyclability and longer life proves to be a stand out option in the roofing industry.
