Urban Heat Island Effect & How Cool Roofs Can Help Reduce It

In urban areas, buildings, roads and other infrastructure replace open land and vegetation. Surfaces that were once teeming with vegetation become impermeable and dry. These changes cause an “island” of higher temperatures in the landscape.

In cities, dark-surfaced buildings and asphalt pavement absorb a considerable amount of light and radiation. They emit them as heat, warming up the surroundings. As a result, cities heat up more than rural areas, where structures are less concentrated. They also hold onto heat longer than rural areas do.

Mascon Inc., your roofing contractor for cool roofs, discusses ways to reduce the island effect.

Light Colors

The dark surfaces of urban structures heat the area. As such, the logical solution would be to lighten their colors to reduce heat. Urban planners may paint structures white or other light colors. This is a simple yet effective technique that helps in reversing the urban heat island effect.

Reflective Coatings

Low-reflectivity coatings can be applied to non-white surfaces to reduce the amount of heat a building absorbs. They reflect invisible radiation without reflecting all light. They can help keep a building quite cool . Certain high-reflectivity coatings can also be applied to asphalt roofing. Turn to Mascon Inc. for commercial roof installation, maintenance and repairs.

Green or Cool Roofs

Green or cool roofs on city buildings are gaining popularity. A green roof is a roof that includes plants and vegetation–it’s not always colored green. They harness the same evaporative cooling effect of vegetation, preventing the building’s roof from absorbing heat.
