etoile note

From estimation to final payment everything went extremely well. From initiation of the project and throughout the process, customer service employees were always listening. There was a delay in the timeline but it was totally justified because of the bad temperature. I was kept informed from beginning to end and that is what is important. The workers were clearly qualified, they arrived with clean equipment, uniforms, safety equipment etc. My roof is complex and everything has been done in a clean, efficient and professional way... I only have good words for this company. Hats off to you!

An important note about flat roofs

According to the National Building Code of Canada, all properties must meet proper aeration and ventilation standards. Failure to adhere to these standards will void the manufacturer’s warranty. Our qualified roofers ensure that your roof’s ventilation system conforms to your flat roof’s structure and insulation requirements.


Types of membranes

Several types of roofing membranes are available on the market. Refer to this article about Roofing Materials and Types of Roofs for more information. We also install green roofs. Ask your estimator about RénoVert or other available tax credits which can help minimize the budgetary impact. Learn more about tax credits by reading: A Tax Credit for Green Roofs?
