SANGOBUILD Roof Ventilation Innovation: An Ideal Stone-Coated Metal Roof Solution for India's Hot and Humid Climate

As demand for high-performance and long-lasting roofing materials continues to grow across India's residential and commercial construction sectors, global roofing systems leader SANGOBUILD announces that its stone-coated metal tiles have become the ideal solution for addressing the challenges of India's tropical climate—offering excellent compatibility with ventilation systems and superior weather resistance.

Much of India experiences year-round high heat and humidity, making effective roof ventilation a key factor in enhancing indoor comfort and extending the lifespan of buildings. Drawing from global climate data and successful applications in similarly humid regions such as Southeast Asia and Africa, SANGOBUILD has developed a six-part ventilation strategy tailored for the Indian market:

1. Combined Ridge Vent and Soffit Intake System

SANGOBUILD's stone-coated metal tiles support continuous ridge ventilation, allowing hot air to escape efficiently. Intake vents installed at the eaves create a natural airflow cycle, resulting in sustained cooling beneath the roof structure.

2. Use of Ventilated Batten Systems

By installing battens between the tiles and the roof deck, an air gap is formed that significantly reduces heat transmission and moisture accumulation. This system is especially suited to SANGOBUILD's lightweight tile design, maintaining structural stability while improving thermal performance.

3. Auxiliary Ventilation Devices: Roof Turbines and Static Vents

For low-wind or poorly ventilated areas, such as Kerala and Tamil Nadu, SANGOBUILD recommends pairing its roofing system with turbine vents or static ventilators to enhance airflow and combat excessive humidity.

4. High-Reflectivity Radiant Barrier Underlayment

SANGOBUILD offers energy-efficient underlayments that reflect over 70% of solar radiation, reducing heat absorption by 1.4–7 times compared to traditional materials—greatly improving indoor energy efficiency.

5. Optimized Roof Pitch and Extended Overhangs

A minimum roof pitch of 20° is recommended to encourage airflow, while extended eaves help shade exterior walls and reduce indoor heat gain. This approach blends practical climate adaptation with modern tropical design aesthetics.

6. Routine Maintenance for Lasting Performance

SANGOBUILD emphasizes the importance of regularly clearing vents and inspecting airflow systems to maintain efficient ventilation and extend the life of the roofing system.

Additional Advantages Tailored for the Indian Market

1. Monsoon-Ready Waterproof Ventilation:

All ventilation components are built with water-resistant structures to ensure airflow continues even during heavy rains without risking water ingress.

2. Compliant with India's NBC and ISO 9001 Standards:

SANGOBUILD products are certified under multiple international quality and construction standards, ensuring easy integration with local building practices.

"At SANGOBUILD, we don't just supply roofing materials—we deliver comfort, sustainability, and long-term value. Pairing our stone-coated metal tiles with smart ventilation design is the future of tropical roofing," said the company's Marketing Director.
