The installation of green roofs is becoming increasingly popular with Quebec homeowners.
This type of roof offers enormous advantages in addition to being environmentally friendly.
There are two main categories of green roofs.
The first is the intensive green roof, often associated with a rooftop garden, terrace or vegetable patch.
The second type of roof is uncultivated, i.e. nothing grows on it.
It goes without saying that the first type of green roof, with a crop or plantation, requires greater attention and rigorous maintenance.
Owners don’t usually complain about these particularities, since this type of roof is fast becoming an integral part of the homeowner’s lifestyle.

What are green roofs and are they popular in the Montreal area?

Green roofs are often composed of a multitude of layers resembling plastic or rubber.
It’s true that most green roofs are installed on flat roofs, but this isn’t always the case, since it’s possible to install or repair them on sloping roofs.

The first layer is a membrane, either elastomer or a plastic derivative.
When properly applied by professionals, it provides an excellent seal against the weather and climate changes possible in the city of Montreal.
The second layer retains a sufficient quantity of water for vegetation to thrive without having to drain the green roof all the time.
The third layer is a geotextile membrane that filters the roof.
The last layer before the vegetation layer is a form of fertilizer and soil that will enable the vegetation to grow.

Why install or repair a green roof in Montreal?

Green roofs make Montreal a more pleasant place to live for all residents.
They reduce heat islands, especially during the city’s long heat waves.

Advantage #1 of green roof installation and repair – Aesthetics

Greenery can sometimes be a rarity when we live in the city, be it Montreal, Laval or the South Shore.
These roofs offer undeniable aesthetic appeal thanks to their natural greenery.

Benefit #2 of green roof installation and repair – Insulation

Temperatures in Quebec fluctuate enormously.
This type of roof, with or without vegetation, provides adequate insulation for the region.
In fact, it’s even preferable to have a green roof in summer, since the sun’s energy is normally absorbed and transformed by the vegetation.

Benefit #3 of green roof installation and repair – The vegetation

When a green roof is well cared for, it’s possible to grow an entire vegetable garden on it, cultivating fruits, vegetables and all kinds of herbs.

Advantage #4 of green roof installation and repair – long service life

Green roofs, when properly maintained and repaired when necessary, offer long life to building owners.
They can last up to 30 years after installation.

Disadvantages of installing or repairing a green roof in Laval

The city of Laval generally has few flat roofs ideal for installing a green roof.
That said, the majority of disadvantages occur during installation or repair of the roof, regardless of location.
The biggest disadvantage of this type of roof is its weight.
Before installation, you need to call in a professional who can assure you that your roof will be able to support a green roof.
If necessary, the roofer will suggest structural modifications.
This type of roof is also expensive, which may discourage some.

Green roof maintenance on the South Shore

A vegetable garden and a roof with a crop will certainly require a lot of maintenance.
It may even be necessary to include an irrigation system.
Insurers may sometimes require annual maintenance to be carried out and the report sent to the insurer.
Regular maintenance is necessary to ensure that no major repairs are required to the roof at the time of installation.
