A flat roof needs proper protection since the snow, ice and rain can accumulate on it. The two-layer elastomeric membrane (composed of a polyester reinforcement and a layer of elastomeric bitumen) is thick and rubbery. It is the most durable roofing membrane since its two layers make it very solid. Additionally, the joints are welded by fusion, which means that water can’t penetrate through!
Learn moreThe EPDM membrane is a thick and waterproof synthetic rubber. It offers an excellent quality/price ratio as it is very durable (between 25 to 35 years with maintenance as needed). It is a 100% waterproof covering that is resistant to weathering from: rain, wind, hail, high winds and UV sun rays. It is an ecological choice as it is recyclable at the end of its life! This covering is 100% waterproof and made to resist damage from high winds, heavy rain, hail and sun rays. It's entirely recyclable at the end of its lifecycle, making it an eco-friendly choice.

Learn moreThe TPO membrane is a single-layer membrane made from a solid and 100% waterproof thermoplastic. The joints are heat-sealed with hot air (without chemical products), which means that no water infiltration is possible. A maintenance held every 6 months makes it possible to verify if small reparations are necessary or if the sealing around the roof equipment needs to be redone. Snow removal from the roof by roofers helps prevent it from damage.

Learn moreI am very satisfied with the overall work of the whole team. Samuel is a man of his word, polite and he delivers the expected results and respects the agreed deadlines. The work is exemplary and done according to the rules of the art. After doing business with several trades in recent months, I can confirm that you got a good deal and that you will not regret it.
Our roof was leaking. Very good and fast emergency repair and roof repair service. Courteous staff explaining at each step the why and how of the repair of my roof thus avoiding any problem. We wanted to respect the design of our roof, such as the visible flashings of our storefront, and everything was done as we wanted. They left the place clean.
Thanks to the whole team!
I discovered Platypus construction by chance while they were working on a project near my home. The very day of my call I already had the quote, two weeks later my roof and my skylight were refurbished. I recommend them without hesitation, a professional, attentive and efficient team. All at a very good price.
After having made many submissions, we chose to do business with Samuel from Ornithorynque to redo our shingle roof in the summer of 2022. Samuel accompanied us very well from start to finish. He was always available to answer our questions and concerns and made sure that everything, down to the smallest detail, was to our complete satisfaction. Samuel is honest, competent and concerned about a job well done. He greatly inspired us with confidence and we were not disappointed. I strongly recommend this company.
We had a chimney (bricks) and a skylight to remove and close. This is a flat roof on a duplex. The team came to do the work in the spring of 2022 and no problem since. Competitive price and job well done.
I never write a review on Google, but with this company, I want to say how satisfied I am. I was quite nervous about taking on this kind of work, but I felt confident and well guided through the process. The team on site was efficient and really pleasant. Everything was left in an astonishing cleanliness considering what it generates to tear off a roof to install another. The execution deadlines were well respected and the representative was present from start to finish. Really, I recommend!
Very transparent during the bid visit on the work to be done and how it would be done. The team during the work showed me where the infiltration had taken place and the condition of the roof before putting on the new membrane. They protected the ground facilities around the house and did a thorough cleaning before leaving. Very satisfied.
Excellent service, they were available quickly and did quality work in addition to providing valuable advice. I had questions about the humidity in the bathroom and the skylight they had changed. Samuel came the next morning to come and see. He took the time to think about it and came back to me with a solution the same evening. In short, I highly recommend!
The seller was very present, available and friendly. The employees were very polite. The work was done quickly with professionalism. We were very impressed with the service offered by this company. We warmly recommend her.
