Expertise
Les Toits Vertige’s expertise is based on German principles and technologies. World leader in green roofing since the 1980s, Germany now has more than 13 million square meters (145 million sq. ft.) of green roofs. These results were greatly influenced by the creation of programs, policies and documentation on which our company roots its quality standards.

One of them, the FLL "Guide Line" manual is a work standardizing the implementation of green roofs. The design of our projects is usually based on this manual. All aspects of green roofs are covered in this guide allowing it to be one of the references that are most conducive to our field of expertise.

For the sake of quality, we strive to offer the products best suited to the climatic conditions in Quebec. To do so, all ranges of green roofs that we install have been tested for a year before being marketed. We make sure to offer a product that is representative of our winter’s hardship and specific needs. In addition, all of our projects and installations have manufacturing guarantees up to 20 years. The professionalism of Les Toits Vertige can offer its customers the best services available on the market.
