How does the color of a roof surface impact its energy efficiency?

The color of a roof surface significantly influences its energy efficiency, primarily due to the way different colors interact with sunlight. Darker colors tend to absorb more solar radiation, which leads to an increase in the roof and, consequently, the interior temperature of the building. This can result in heightened energy expenditure on cooling systems during warmer months, ultimately affecting the overall energy efficiency of the building.

In contrast, lighter-colored roofs reflect more sunlight, thereby reducing heat absorption. This reflective property can lead to lower temperatures both on the roof surface and within the building, decreasing the demand for air conditioning and improving energy savings.

While the color of a roof can certainly influence energy efficiency, it is vital to note that not all colors perform the same concerning energy absorption and reflection. Thus, the distinction between light and dark roofs is crucial for understanding their impact on energy usage.
