As the roofing world evolves toward sustainability, one bold question is surfacing: Can plant-based materials like hemp or algae replace traditional asphalt shingles? With climate-conscious design on the rise, bio-based shingles are gaining attention as a possible eco-alternative to petroleum-based roofing. But how do they hold up in performance, especially in Kerala’s tropical climate?
At Scaffs India, we blend cutting-edge roofing solutions with a commitment to innovation. Here’s our take on whether bio-based roofing can truly compete with the proven reliability of asphalt shingles.
What Are Bio-Based Roofing Shingles?
Bio-based shingles are made using renewable plant materials like:
Hemp fibres: Known for strength and flexibility
Algae compounds: Used in bioplastics or oil-based coatings
Agricultural waste: Such as jute, flax, and coconut husk
Natural binders or bio-resins: To hold materials together under weather exposure
Unlike petroleum-based asphalt shingles, these materials are designed to offer lower carbon emissions, renewable sourcing, and potential biodegradability.
Can They Compete with Asphalt?
Let’s compare bio-based shingles with some of Scaffs India’s most popular materials—like asphalt 3-tab shingles and architectural roofing shingles:
1. Durability
Bio-based shingles are still in development. While hemp offers tensile strength, and algae-derived bioplastics can be tough, most bio-based shingles haven’t yet achieved the 20–30-year lifespan of asphalt products—especially under Kerala’s monsoons and UV exposure.
2. Weather Resistance
Moisture is a major challenge. Unless treated with waterproof coatings or combined with synthetic stabilisers, bio-materials are susceptible to rot, fungal growth, or material fatigue. By contrast, premium designer shingles from Scaffs India are engineered for heat, rain, and salt-laden winds.
3. Eco-Impact
Here’s where bio-based shingles shine. Hemp and algae can be grown rapidly, sequester carbon, and require minimal energy to process—making them a climate-positive choice compared to petroleum-heavy asphalt production.
Are Bio-Based Shingles Right for Kerala?
Not quite yet. While the concept is exciting, Kerala’s climate poses serious durability tests—from heavy rainfall to high humidity and temperature swings. That said, bio-based shingles may still be viable for:
Temporary or experimental structures
Low-slope cottage roofs
Eco-resorts and off-grid wooden cottages
Light-load installations like mudroom cottages
What’s the Alternative for Now?
If you’re looking for eco-conscious roofing available today, Scaffs India recommends:
Recycled asphalt shingles – Durable, affordable, and made with reused materials
Solar roof tiles – Combine energy generation with a sleek finish: Tejas Borja solar-integrated tiles
Low-VOC accessory products – Help improve indoor air quality and reduce toxic emissions

The Future Is Green—but Needs Testing
Bio-based shingles are a promising innovation, but they’re still evolving. They’re not yet ready to replace asphalt in high-performance tropical applications, but they signal where roofing is headed: toward a more regenerative, resilient future.
