A white roof offers numerous benefits not only for homes, but also for warehouses and other industrial and commercial facilities. This solution, both economical and ecological, aims to reduce summer temperatures and, more broadly, increase the energy comfort of buildings. Let’s take a closer look at the benefits of a white roof... for your wallet and the environment!

In other words, while black stores 90% of the light spectrum, i.e. the heat it receives, white reflects this same heat, which considerably reduces the temperature inside the building.

🔥It might not be immediately obvious, but regardless of the type of building, the roof doesn’t necessarily protect against heat. Quite the opposite: the materials used often act as a receptacle for rising temperatures. However, switching to a white roof provides, conversely, the thermal comfort expected when it’s hot outside.

White roof on building

Similarly, especially for buildings located in densely populated cities, a white roof helps mitigate the urban heat island effect ( read more about it ) . Normally, in concrete neighborhoods, most buildings have dark roofs, and the floors are usually gray. All of this leads to heat exchange and a significant increase in ambient temperature.

🌡 Conversely, white roofs are one of the key elements in maintaining cooler temperatures in cities.

Reduce CO2 emissions

In addition to energy savings, a white roof offers other benefits, particularly for businesses with large roof areas that need to air-condition their spaces. A white roof naturally air-conditions buildings , thus limiting electricity consumption and heat release into the atmosphere.

Extend the life of the roof

A white roof paint is also a way to extend the life of your roof. How? This prevents roofing materials from being damaged by the sun and temperature fluctuations.

How to paint your roof white?

As in Greece where traditional houses are white, it is possible in France to paint a roof white while benefiting from the same thermal advantages to limit the effects of heat.

💧 A reflective roof coating suitable for buildings, known as ” cool roof ,” now offers a remarkable result in lowering indoor temperatures.

On large buildings such as company headquarters , warehouses and factories , the cool roof is particularly suitable. While the cost of electricity is a major issue today, white roofs are an effective method for reducing the level of air conditioning. To measure this advantage, it is necessary to rely on a solar reflectance index (SRI) equal to or greater than 78. Of course, the higher this index is, well beyond this figure, the greater the energy efficiency of the cool roof.

Call on cool roof professionals

While a white roof offers many benefits, it may not be suitable for all types of buildings. In addition to being reflective, the product must also adhere perfectly and prevent stains from affecting it.

✅ In any case, before opting for a white roof, consult a cool roof specialist who can assess the specific needs of your building and recommend the best solution.

A white roof offers many benefits to businesses, from thermal efficiency to energy savings, as well as extending the roof’s lifespan. While many material solutions and installation techniques are suitable for this type of roof, hiring a white reflective paint professional will help you choose the best solution for your building.
