The specificities of a flat roof
Above all, it should be noted that a flat roof is not strictly flat. It is always positioned with a low slope, essential for evacuating rainwater. The frame is also inclined between 2 to 15 °, to ensure the evacuation function.
What are the possible configurations?
There are 3 main possible configurations for a flat roof:
- A cold roof: its insulation quality is lower;
- A warm roof: it offers a quality insulation system;
- An inverted roof: this expensive technique involves preserving an external insulation layer to protect the waterproofing.
What are the coatings of flat roofs of buildings in Laval?
The flat roof is popular with owners of residential, institutional or commercial buildings in Laval. It brings a touch of modernity to the buildings.
Roofers recommend certain coatings that are better suited to climatic conditions in Quebec, in particular:
- The elastomeric membrane;
- The vinyl membrane;
- Synthetic rubber membrane;
- The asphalt roof.
The elastomeric membrane
What are its particularities?
An elastomeric membrane is a petroleum-based product. It is recognizable by its appearance similar to rubber. It uses two distinct layers during its installation. The first seals the roof, while the second defines the color of the structure.
These two layers are fused together with a torch, once superimposed to adhere to a surface. It is important that the owner chooses the color of the roof beforehand, because it is the choice of the second layer.
How is the installation going?
First of all, you should know that this type of recovery is very common in Quebec. At Toiture Couvreur Laval, we have workers who are perfectly comfortable with flat roofing work. It should be noted that quality services guarantee a lasting result, with longevity of up to 35 years, provided that regular maintenance is observed.
An installation carried out according to standards and with the right tools is crucial for a roof that is resistant to weather and snow. It is important to secure it to keep it stable despite strong winds.
What about repairs?
Repairing a flat roof is not inevitable, as long as the structure is properly maintained. However, we must be prepared for this eventuality given the irregular temperatures which favor the deterioration of roofs in Quebec.
It remains prudent to always carry out an inspection before any work to define the needs of the structure. Contact professional craftsmen to find the best solutions to guarantee the durability of the structure.
The repair of the elastomeric membrane involves specific procedures. In addition, it is delicate given the use of the torch which could cause a fire.
The vinyl membrane (TPO)
A vinyl membrane belongs to the category of single-ply coatings. It is characterized by its shiny appearance and smooth texture, making it easy and quick to clean.
In addition to maintenance, the TPO membrane is resistant to mold, bacteria and insects. This quality is one of the reasons why industrial plant owners choose flat covers. The downside lies in its fragility compared to cracks and tears, which can generate expensive repairs.
Asphalt and gravel
Asphalt and gravel are suitable coating alternatives for your flat roof. It tolerates temperature variations well, often occurring in Laval. Its lifespan is estimated at around twenty years.
Annual inspection is required to prolong the durability of the coating. It is important to check the structure to make sure it is watertight. Otherwise, adding gravel will be necessary.
Synthetic rubber membrane (EPDM)
The synthetic rubber membrane is often the choice of owners of flat roofs equipped with a green roof in Laval. It is practical thanks to its resistance to molds and bacteria.
It is almost immune to tears. The coating is therefore an appropriate choice to reduce the maintenance of the plant surface.
Advantages of a flat roof
A flat roof has the advantage of being able to act as a roof terrace, interesting for arranging a living space. It brings modernity, and above all a touch of originality to a building. Tenants use it as a separate room, interesting to enjoy the outside environment.
You let your imagination run wild by choosing this type of roof. You can indeed do many activities there, including gardening, or make it a relaxation area.
Good to know about multi-layer and single-layer coatings
Multilayer coatings include elastomeric membrane and asphalt / gravel combo. They are appreciated for their durability. However, this quality comes at a price that could weigh heavily on the wallet. Installation work is much easier and faster by investing in these materials.
Single-layer coatings, including vinyl membrane and synthetic rubber membrane, are recyclable. Also, they are more affordable unlike their multi-layered counterpart. Their disadvantage lies in their lower longevity.
