V Boards (GI Corrugated Sheets): What You Need to Know
V boards — also called GI (Galvanised Iron) corrugated sheets or zinc sheets — are the most widely used roofing for temporary and semi-permanent structures in Kerala:
- Lightweight and easy to install — no heavy structural support needed
- Available in standard lengths from 6 feet to 12 feet
- Galvanised coating prevents rust — thickness of coating matters for Kerala
- Not suitable as permanent roofing for inhabited spaces — conducts heat and noise
V Board Thickness Guide
| Gauge | Thickness | Best For |
|---|---|---|
| 24 gauge | 0.63mm | Temporary sheds, site offices |
| 22 gauge | 0.80mm | General purpose — most common |
| 20 gauge | 1.00mm | Permanent sheds, godowns |
| 18 gauge | 1.25mm | Industrial, heavy-duty applications |
For Kerala: Use minimum 22 gauge for any structure that needs to last more than 3 years. Thinner sheets corrode faster in Kannur’s coastal humidity and monsoon rainfall.
Colour Coated Roofing Sheets for Car Porches & Sit-Outs
Colour coated steel sheets (PPGI — Pre-Painted Galvanised Iron) are the best choice for car porches, sit-outs, and building extensions in Kerala:
- Polyester coating — standard option, good UV resistance
- PVDF coating — premium, best colour retention and corrosion resistance for coastal Kerala
- Available in profiles: trapezoidal, corrugated, and standing seam
- Common colours: Terracotta Red, Brick Red, Stone Blue, Bottle Green, Charcoal Grey
Polycarbonate Sheets for Skylights & Pergolas
Polycarbonate sheets are used where you want natural light through the roof — pergolas, covered courtyards, plant areas, and skylight sections:
| Type | Features | Best For |
|---|---|---|
| Clear polycarbonate | Maximum light transmission | Plant rooms, display areas |
| Opal / Milky white | Diffused light, no glare | Living area skylights, sit-outs |
| Tinted (Blue / Green / Bronze) | Heat reduction + light | Car porches, open courtyards |
| Twin-wall / Hollow sheet | Better insulation than solid sheet | Permanent covered areas |

Terrace Waterproofing for RCC Roofs in Kerala
For RCC flat roofs and terraces, waterproofing is not optional in Kerala. Without it, water seeps into the slab and causes leaks in the ceiling below within 2–3 monsoons:
- Integral waterproofing compound — mix into concrete during casting (Dr Fixit, Fosroc)
- APP/SBS bitumen membrane — torch-applied sheet over existing terrace (5–10 year solution)
- Crystalline waterproofing — penetrates concrete and blocks capillary pores (Dr Fixit Krystol)
- Liquid applied membrane — brush or spray applied, good for small terraces

Frequently Asked Questions
What is a V board used for in Kerala?
V boards (GI corrugated sheets) are used for roofing sheds, site offices, godowns, compound walls, and temporary structures. They’re lightweight, fast to install, and cost-effective.
Which roofing sheet lasts longest in Kerala’s climate?
PPGI colour coated sheets with PVDF coating last 20–25 years even in Kannur’s coastal humidity. Tata Shaktee GI sheets are the most trusted for general use.
Is polycarbonate roofing good for Kerala car porches?
