Selecting the right roofing material is crucial for building or renovating a home in Canada. The varied Canadian climate — with cold winters, hot summers, and plenty of rain and snow — requires roofs that are strong, energy-efficient, and can handle different weather conditions. Here’s a look at some of the most popular types of roofing sheets used in Canadian homes, along with the benefits and drawbacks of each.
1. Metal Roofing Sheets

- Noisy: Can be noisy during heavy rain or hail, though insulation can help.
2. Asphalt Shingle Roofing
Overview:
