Cool Roofing in Canadian Climates

Cool Roofing in Canadian Climates

It is theorized that dark-coloured roofs can contribute to the urban heat island effect (the temperature in cities is higher than the surrounding unpopulated areas).

Some reflective roofing products have been listed as “Energy Star qualified”, a program that makes it easy for consumers to identify and purchase energy-efficient products.
