1.1 What Is a Green Roof System?

A green roof system, also known as a planted roof system, involves covering a building’s roof with vegetation, a growing medium, and specialized layers for drainage and waterproofing. It integrates nature into construction, making buildings with green roofs a hallmark of modern eco-friendly architecture.

2. Types of Green Roofs

Green roofs are categorized into two types:

2.1 Extensive Green Roofs:

  • Lightweight and designed for minimal maintenance.
  • Best for simple green roof gardening with grass or low-maintenance plants.

2.2 Intensive Green Roofs:

  • Suitable for creating elaborate landscapes, including gardens and even small trees.
  • They require robust structural support and are ideal for large-scale gardening roofs.

3. Advantages of Green Roofs in India

3.1 Thermal Insulation

  • Green roofs act as natural insulators, reducing indoor temperatures significantly.
  • This makes them particularly beneficial in India’s hot climate, lowering energy costs for cooling.

3.2 Rainwater Management

  • The vegetation in planted roof systems absorbs rainwater, reducing runoff and preventing urban flooding.

3.3 Urban Greening

  • Cities like Mumbai, Bengaluru, and Delhi can use living green roofs to combat the loss of green spaces, improving air quality and reducing the heat island effect.

3.4 Environmental Benefits

  • Green roofs promote biodiversity, filter pollutants, and improve carbon sequestration, making them a prime example of environmentally friendly roofing.

3.5 Aesthetic Appeal

  • A greenery roof adds visual charm, transforming dull rooftops into lush gardens or recreational spaces.

4. Green Roof Sheeting and Installation

Installing a green rooftop involves multiple layers to ensure durability and functionality:

  • Waterproofing Membrane: Protects the roof from water damage.
  • Root Barrier: Prevents plant roots from penetrating the roof.
  • Drainage Layer: Facilitates water flow and prevents clogging.
  • Green Roof Sheeting: Holds the soil and vegetation in place.

For intensive green roofs, additional structural support may be needed to handle the load.

5. Green Roof Cost in India

It can cost anything from a few thousand dollars to thousands of dollars more than conventional roofing to install a grass roof, also known as a living green roof, due to differences such as size, design difficulty, and type of vegetation. On average:

  • Extensive green roofs: ₹800-₹1,500 per square foot.
  • Intensive Green Roofs: Rs 2000–Rs 4000 per sq ft.

Perhaps that is why, even though the initial cost is relatively high, the money that is used to pay the bills every month in the long run is cheaper than the cost of the windmills would be.

6. Green Roof in India: A Concept to Implement

6.1 Residential Buildings

  • People are embracing green roof gardening to design sustainable domestic environments for outdoor spaces.

6.2 Commercial Complexes

  • The presence of green roofs in malls and office buildings improves the sustainability factor and hence attracts people's attention to using sustainable facilities.

6.3 Urban Infrastructure

  • In airports and metro stations, the green rooftop has found a place as an additional and ornamental feature to increase utility.

7. Challenges and Solutions

7.1 Structural Feasibility

  • As essential structures, the roofing systems of earthen architecture buildings may need to be strengthened to accommodate a grass roof.
  • It is therefore advisable to employ the services of professional structural engineers.

7.2 Maintenance

  • While extensive roofs require minimal upkeep, intensive roofs need regular care.
  • Automated irrigation systems can simplify maintenance for gardening roofs.

7.3 Climate Suitability

  • India’s diverse climate requires selecting plants suited to local conditions to ensure the longevity of planted roof systems.

8. The Future of Green Roofs in India

As more people embrace the effects of climate change and sustainability when constructing infrastructure, green roofs have become fashionable in architectural design in urban design. Pune and Hyderabad have seen the inclusion of the green roofs in the smart city projects, claiming that it is capable of transforming the urban lifestyle.

It is suggested here that through the incorporation of ecological roofing such as green roofs, environmentally difficult conditions prevailing in India coupled with the creation of a healthier urban environment are capable of being tackled.
