When building a house, most of the focus goes into what we can see: the tiles, the paint, and the interior finishes. But one of the most critical parts of a building is actually hidden under the eaves.
If you’ve ever wondered why some houses feel like an oven during the day, or why relatively new roofs start to show signs of timber rot and sagging, the answer is simple: Lack of ventilation.
What are Vent Boards?
Vent boards are specialized, perforated fiber-cement panels installed in the soffits (the underside of your roof eaves). Their primary job is to allow your roof to “breathe.” By providing a constant path for air to flow into the roof space, they prevent the buildup of trapped heat and moisture that destroys standard building materials.
1. For the Homeowner: Comfort & Cost Savings
As a homeowner, your house is your biggest investment. Without proper ventilation, you face two major “silent killers”:
- The Oven Effect: In warm climates, heat gets trapped in the “dead air” space above your ceiling. This heat radiates downward, making your rooms uncomfortably hot and forcing your AC (if you have one) to work twice as hard.
- The Damp Cycle: At night, moisture from the air can condense inside your roof. This leads to damp smells, mold on your gypsum ceilings, and peeling paint on your eaves.
The Solution: Vent boards allow natural convection to pull cool air in and push hot air out, keeping your home naturally cool and bone-dry.
2. For the Fundi: Strength & Ease of Installation
For contractors and fundis, using the right material means fewer “back-calls” for repairs.
- Stone-Strong Durability: Unlike timber eaves that warp or thin plywood that sags, Builders Duka Vent Boards are made of high-density fiber cement. They don’t bend, they don’t rot, and they don’t feed termites.
- Precision Fit: These boards are engineered for precision. They provide a clean, modern finish that is much faster to install than traditional timber slats, giving the project a “Class A” professional look.
- Safety First: They are A1 fire-rated. In the event of an external fire, vent boards act as a shield, preventing flames from easily entering the roof structure.
Pricing and Where to Buy
Proprietary Vent Boards are an investment in the longevity of the structure. While prices may vary based on specific project requirements and board thickness:
- Price Range: Expect to invest between KES 1,200 and KES 1,800 per board (Standard sizes).
- Availability: These specific, high-performance Vent Boards are available solely at Builders Duka Kenya.

Frequently Asked Questions
1. What exactly are Vent Boards, and why do I need them? Vent boards are specialized, perforated fiber-cement panels installed on the underside of your roof eaves (the soffits). Their job is to allow your home to “breathe” by creating a natural path for cool air to enter and hot, moist air to escape. Without them, your attic becomes a heat trap, leading to high indoor temperatures and structural rot.
2. Are Vent Boards better than traditional timber eaves? Yes. Traditional timber often warps, rots, or requires constant repainting due to moisture exposure. Builders Duka Vent Boards are made from stone-strong fiber cement that is 100% moisture-proof, termite-resistant, and A1 fire-rated. Once installed, they are a permanent, maintenance-free solution.
3. Do the ventilation holes allow insects or pests into my roof? No. Our proprietary Vent Boards are engineered with precision-sized perforations. These holes are small enough to keep out rodents and large insects while still allowing for maximum airflow. You get all the ventilation without the unwanted guests.
4. Can I use Vent Boards with a traditional timber roof or only with Light Gauge Steel (LGS)? They work perfectly with both! While they are the gold standard for modern LGS construction, they are also a massive upgrade for traditional timber-framed houses. If you are a fundi, you’ll find them much faster and cleaner to install than fitting individual timber slats.
5. How much do they cost? Investing in the longevity of your home is more affordable than you think. Builders Duka Vent Boards typically range from *KES 1,200 to KES 1,800 per board, depending on the specific dimensions required for your project.
