I was looking for a company to replace my shingles after the 2018 wind storms. Luckily I came across a video by famous Toronto interior designer Mr. Peloso describing the process of installing a metal shingles on his own house. The metal shingles were designed and installed by a company called New Steel Roofers. So I called them up. Chris, the salesperson was knowledgeable about metal roofing products and advised on the benefits of the hidden fasteners used by the painted slate. No exposed fasteners = a more durable, water tight installation. The metal shingles are installed over the existing asphalt, which is first wrapped with a water-tight membrane. Ridge venting was also added to the roof to improve the overall ventilation. The installation was done over the winter in 2018 by an expert crew. Max did a great job co-ordinating the installation. I've had no more shingles falling off the roof since then! Thanks Max and Bruce!
