Roof Gardening: Transforming Rooftops into Green Paradises

Imagine stepping out onto your rooftop, not to a dull concrete slab, but into a vibrant oasis of plants, herbs, and vegetables. That’s the promise of roof gardening—an eco-friendly movement that’s turning dead urban spaces into living, breathing sanctuaries.

Whether you’re a city dweller with limited ground space or an eco-conscious homeowner, roof gardening isn’t just a trend—it’s a smart, sustainable way to live greener.

Why Roof Gardening Is More Than Just a Trend

Urban areas lose 2.5% of green space annually due to construction and expansion.
Rooftops account for up to 25% of urban surface area—a massive untapped opportunity.
Green roofs can reduce surrounding air temperatures by up to 5°C, helping cities fight the heat island effect.
