This heat is released at night, causing the air temperature to remain high. Installing reflective roofs helps reduce the heat island effect, decreasing the amount of smog in the air and benefiting the entire community. Reflective roofs can reduce roof surface temperature by up to 100oF preventing the sun's heat from transferring into the home or building. The home or building owner may be able to purchase a smaller, less-expensive cooling system. Extended roof life.
Roofs undergo significant expansion and contraction as they heat and cool throughout the day.
Heat absorbed by the roof can also accelerate degradation by ultraviolet rays and water. A reflective roof can reduce the amount of thermal shock that occurs on the roof surface and make the roof last longer. Reduced Heat Island Effect. As a result, building owners may be able to purchase smaller, less expensive HVAC systems. Homes and buildings located in hot and sunny climates will realize the greatest energy and cost savings.
