Mr. Mongeau, the biggest challenge with this kind of roof—and I have worked in this area—is the weight of the snow. In the event of a heavy snowfall—we often get heavy snow in Ottawa and a foot of snow can fall, melt quickly and still be very heavy—is there a way to make it melt more quickly? Or could there be 60 cm of snow on the roof for four or five days with the potential to cause problems?
