What is a Cool Roof?

For centuries, builders and architects have utilized light-colored roofs to reflect sunlight and maintain cool temperatures inside buildings during hot weather. However, the usage of materials such as asphalt and tar in roofing has unintentional and adverse impacts on the environment, causing the creation of urban heat islands.

Urban Heat Islands and Environmental Impact

Urban environments tend to be warmer than rural areas, with temperature differences ranging from 2°C to 5°C and even higher on scorching summer days. The urban heat island effect can raise temperatures by as much as 20°F compared to nearby rural areas. This phenomenon has serious consequences for the environment and human health, as demonstrated by the high temperatures roofs can reach, such as exceeding 170°F in cities like Ahmedabad.

The Cooling Effect of Cool Roofs

A cool roof reflects more sunlight and absorbs less solar energy than a conventional roof, similar to how light-colored clothing keeps you cool on a sunny day. Traditional roofs can reach temperatures of 150°F or higher, while reflective roofs can stay more than 50°F (28°C) cooler under the same conditions. This not only leads to energy and cost savings for air-conditioned buildings but also enhances comfort and safety in non-air-conditioned buildings by reducing heat transfer into living spaces.

Benefits of Cool Roofs

Installing a cool roof offers numerous advantages for buildings and occupants, including energy bill reduction, improved indoor comfort and safety, and extended roof service life.

Energy Bill Reduction

Cool roofs minimize the need for air conditioning, resulting in significant energy bill savings. By reducing cooling demands, older and inefficient air conditioning systems can still provide adequate cooling during hotter summers. Additionally, cool roofs may qualify for cost-saving rebates from government programs or utilities, allowing for downsizing of air conditioning equipment and increasing cooling efficiency in the long run.

Enhanced Indoor Comfort and Safety

Cool roofs significantly improve indoor comfort and safety in non-air-conditioned areas by reducing heat transfer from the roof. This creates a more pleasant environment during hot weather conditions and contributes to a better quality of life for occupants.

Extended Roof Service Life

Cool roofs help decrease roof temperatures, which can extend the lifespan of the roof. By reflecting sunlight and reducing solar energy absorption, cool roofs contribute to maintaining a cooler roof surface. This leads to less wear and tear, prolonging the roof's service life and adding value to the building.

MEER Cool Roof Benefits

MEER's cool roofs offer a sustainable solution to combat climate change while promoting sustainable development. These roofs are easy to install, cost-effective, and utilize recycled materials, making them an environmentally responsible choice.

Energy Efficiency and Reduced Greenhouse Gas Emissions

MEER's cool roofs incorporate solar-reflective sheeting, preventing excessive sun radiation absorption and reducing internal temperatures by 6-7°C. This reduces energy consumption by decreasing the need for cooling systems, resulting in lower greenhouse gas emissions and a more sustainable future.

Improved Comfort and Reduced Energy Demands

MEER's cool roofs effectively reduce temperatures in urban areas, creating a more comfortable environment for individuals who lack air conditioning or fans. By eliminating the need for traditional cooling options, cool roofs contribute to reducing energy demands and greenhouse gas emissions. Additionally, the construction of these roofs provides sustainable employment opportunities for low-skilled workers in both rural and urban areas.

Longevity and Sustainability

MEER-treated materials possess exceptional anti-soiling properties, significantly increasing their lifespan compared to conventional white paints.
