With Global Warming, Will White Roofs Become the Norm?

PVC membrane for roll roofs

The scientific community and environmental groups are sounding the alarm: global warming is a phenomenon that can no longer be ignored. Although initiatives are being put forward in several parts of the world, it is obvious that it is not enough to prevent the increase of droughts and the extinction of animal and plant species, among other things. At Couvreurs DM, flat roof experts in the Montreal region (Rosemont, LaSalle, Saint-Léonard, Ville Saint-Laurent, etc.), we contribute in our own way to the environmental cause by installing white roofs.

Heat Waves in Urban Areas: A Deadly Phenomenon Heat waves are getting longer and more frequent. In cities, particularly, atmospheric pollution creates heat islands that make summers almost unbearable, especially for the most vulnerable citizens. Last summer, Montreal experienced its hottest July in 97 years and several deaths in the province were blamed on heat waves. Unfortunately, since this trend is not likely to end soon, we are better off accepting the situation and adjusting our behaviours accordingly! White Roofs: A Simple and Effective Solution As you know, the sun's rays are attracted to dark colours. Thus, grey or black surfaces absorb heat - Try walking barefoot on new asphalt on a sunny day and see how hot it gets! Conversely, white repels the sun's rays. So, considering that roofs of buildings are architectural elements that are more exposed to the sun, we began a few years ago to lighten them up with the help of light shingles, white membranes and white gravel, which has had significant positive effects in several industrialized countries. In France and the United States, in particular, roofs are painted with white reflective paint to create a surprisingly effective "heat shield"! Couvreurs DM: Your Partner for an Eco-Responsible White Flat Roof With climate change, will the white roof become the norm in Montreal and other major cities around the world? Only the future will tell! However, be aware that the RénoVert tax credit rewards homeowners who choose to install a white roof.
