Green roofs are gaining global popularity for their eco-friendly benefits — from cooling buildings naturally to filtering rainwater. But one challenge often overlooked is root intrusion. Without proper engineering, plant roots can penetrate roofing layers, leading to leaks, insulation damage, and structural issues.
In Kerala, where rainfall and humidity fuel rapid vegetation growth, preventing root intrusion is essential for ensuring the long life of green roofing systems.
What Is Root Intrusion?
Root intrusion occurs when plant roots extend beyond the soil substrate of a green roof and push into waterproofing membranes, insulation, or structural layers.
Roots follow moisture pathways into roof cracks.
Over time, they widen gaps, weakening waterproofing layers.
This creates hidden leaks and costly repairs.
Why Root Intrusion Matters in Kerala
High Rainfall → Encourages deeper root growth.
Tropical Plants → Roots spread aggressively in search of nutrients.
Humidity & Warmth → Creates ideal conditions for root penetration.
👉 This makes advanced roofing solutions from Scaffs India a better alternative to traditional flat roof waterproofing.
