Opt for a White Roof in Montreal

With a view to sustainable development and the fight against heat islands, it is now mandatory to have a white roof in certain neighbourhoods of Montreal, particularly on flat roofs. Couvreurs DM offers you the opportunity to easily go green by installing a membrane on your roof in order to benefit from a white roof in Montreal.

The Advantages of a White Roof in Montreal

Traditionally, roofs are dark in color. However, the darker shades attract and absorb UV rays, leading to an increase in the building’s interior temperature and the formation of very hot areas in urbanized environments. This phenomenon makes homes sometimes uncomfortable in summer and often results in a significant and environmentally unfriendly use of ventilation and air conditioning devices.

The installation of a white membrane on a roof allows the sun's rays to be reflected effectively and thus, reduces the heat stored by the roof. This type of installation has many advantages both from an ecological and economic point of view as well as from the point of view of the comfort of the occupants of the building equipped with it. Opting for a white roof contributes in particular to:

Lowering of the building’s interior temperature by several degrees

Reduced energy consumption due to air conditioning and ventilation systems

The reduction of heat islands in urban areas

Roof protection and increase in its lifespan.

White Roofing Membranes

Setting up a white roof in Montreal is quite simple and involves covering an existing flat roof, or one created during a new construction, with an energy-efficient white membrane. There are several types of membranes for this purpose:

The elastomeric membrane

The multi-layer marble aggregate membrane

Each of these membranes has specific technical characteristics that make them more suitable for certain environments rather than others. Couvreurs DM will be able to recommend the membrane that best suits your needs. Whatever material you choose, each white roof membrane is guaranteed to be waterproof, aesthetically pleasing and environmentally friendly. In addition, these eco-responsible devices are very long-lasting, require little maintenance and are weather-resistant.

A White Membrane for a Green Roof or a Roof Terrace

If you are considering creating a green roof, installing a white membrane is a wise choice. Waterproof and durable, it facilitates the establishment of plants by better insulating the roof against heat and helping to improve the quality of the surrounding air. By reducing the temperature locally, it also allows you to create a very pleasant roof terrace, on which you can stay without suffering from excessive heat.
