Asphalt shingles remain by far the most used covering for its style and its many advantages such as its wide variety of colors, styles and shapes, its lower cost, its resistance to bad weather and its ease of installation and maintenance.

Contact our team today to start planning a repair of your sloping roof in Montreal.


The inclination of the slope of your roof directly influences the material that can be used.


For example, slate requires a slope between 15 degrees and 30 degrees and a green roof (LEED), a slope approaching 40 degrees.


The effects of heat, wind, ice and water, as well as the sun’s ultraviolet rays, cause shingles to deteriorate. This deterioration is even more pronounced on roofs that are in direct sunlight, in areas where ice and snow pile up and on sides where the wind is dominant. By having a proper slope and a well-ventilated roof, your roof can last 20 or 30 years, depending on the quality of the shingles.

If you live in an area where discolouration is caused by algae and is a major problem, choose shingles made using a protective system that prevents the risk of discolouration. In addition, it is recommended that you choose a dark colour shingle, on which the spots caused by algae will show up less.
