Why Roofing and Waterproofing Go Hand-in-Hand
In tropical regions like Kerala, roofs endure intense rainfall, high humidity, and extreme heat. A strong roofing system alone is not enough—waterproofing is the hidden shield that ensures the roof performs reliably year after year.
At Scaffs India, we’ve seen how roofing materials and waterproofing techniques must be planned together, especially for homes, resorts, institutions, and prefab cottages in tropical climates.
1. Heavy Rainfall and Roof Vulnerability
Kerala’s monsoon season brings prolonged heavy downpours.
Without proper waterproofing, even durable materials like shingles or tiles can develop:
Seepage through micro-gaps.
Mold and mildew from trapped moisture.
Structural damage over time.
This makes waterproof underlayment and accessories as important as the visible roofing layer.

2. How Roofing Materials Affect Waterproofing
Asphalt Shingles
Lightweight and reliable against rain.
Still require underlayments and flashing for full waterproofing.
👉 Explore Asphalt Shingles.
Architectural & Premium Designer Shingles
Offer deeper layering and better water-shedding ability.
Work best when combined with breathable membranes to prevent condensation.
👉 See Dynasty Shingles and Armourshake Shingles.
Ceramic & Terracotta Tiles
Naturally resist heavy rain and tropical heat.
Require precise installation and waterproof membranes beneath to avoid leakage through joints.

Solar Roof Tiles
Double up as roofing + energy generation.
Require special sealing systems to prevent water seepage around wiring.

3. Waterproofing Essentials in Tropical Roofs
Underlayment Membranes: Act as the secondary barrier below shingles or tiles.
Flashing: Prevents leakage at joints, valleys, and roof penetrations.
Proper Ventilation: Reduces condensation and mold growth.
Drainage Systems: Gutters and downspouts ensure rainwater flows away effectively.

4. Prefab Homes & Waterproofing Challenges
For prefab designs like Wooden Cottages or A-Frame Cottages, waterproofing is critical from the start. Lightweight prefab structures are more vulnerable to tropical rains, making membranes, sealants, and careful shingle/tile placement essential.
Final Word
In tropical climates, roofing cannot be separated from waterproofing. Choosing high-quality shingles or tiles without proper membranes and drainage leads to premature failures.
At Scaffs India, we combine world-class roofing systems with the right waterproofing accessories to ensure buildings remain safe, dry, and durable—even through Kerala’s heaviest monsoons.
