Is Your Zinc Roof Too Hot? Here's How to Fix It!

Zinc roofs are often used because of their affordable price, easy installation, and high durability. However, many users complain about temperatures that are too hot during the day. This happens because zinc has high thermal conductivity, so it absorbs and conducts heat faster than other roofing materials.

If you experience this problem, don't worry! Here are some solutions to keep your zinc roof cool and comfortable.

1. Use a Special Coating of Paint
A layer of thermal coating or special roof paint can help reflect the sun's heat so that the room temperature below is more stable. Choose paint with bright colors such as white or silver for optimal results.

2. Install Insulation or Heat Insulation
Insulation materials such as aluminum foil, bubble foil, or glass wool can reduce the heat entering the room. This insulation is installed under the roof to withstand heat radiation and keep the temperature cool.

3. Add a Ceiling Frame
The ceiling can reduce the direct impact of heat by creating air space between the roof and the inside of the house. The air between the ceiling and the roof functions as a natural damper to reduce the incoming heat.

4. Increase Air Ventilation
Good air circulation will help remove hot air trapped in the room. You can install:
✔ Cross ventilation – Windows or air holes on two opposite sides so that the wind can flow.
✔ Turbine ventilator – A tool that works by utilizing wind to suck hot air from inside the room.

5. Use Additional Coatings on Zinc
Adding a layer such as polycarbonate or bamboo matting on top of the zinc can reduce the intensity of the sun's heat that directly hits the roof. This method is suitable for industrial buildings, warehouses, or houses in tropical areas.

Although zinc roofs easily absorb heat, there are many ways to overcome this. By using reflective paint, insulation, good ventilation, and additional protective layers, you can effectively reduce heat and make the room more comfortable.
