What does this fact has to do with your roof?
Well, when the weather is very hot, especially in big cities such as Montreal, a black roof will attract the heat. When we mix this increased heat with the city’s pollution, we can end up with a smog hidding the beauty of our city and increasing the problems related with pollution.
Having a white roof in Montreal helps to prevent smog creation because it repels the heat instead of attracting it.
simple step can make a great change for our environment. Did you know that asphalt and gravel roofs can also be white by simply replacing the usual gravel with a white marble gravel. See it yourself on this picture!
