Nowadays, green roofs have become quite famous, particularly in those areas which are hot and polluted due to the vegetation deficit. In this article, you will learn about this type of roofing in detail.



What is a green roof?

Also referred to as a rooftop garden, the green roof includes a layer or bed of vegetation on it. These roofing systems control the heat in the air, keep air and the surface of your roof comparatively fresh, and offer shade. By including this style of roofing in your home, you can help your city and environment to reduce the harmful impact of heat island, especially in the day time. It is believed that green roofs can be more refreshing than any other popular style of roofing option as their temperature level is found to be 30–40°F lower. Besides, they can also help in controlling the overall ambient temperature of the city by up to 5°F.

There are many other reasons also for promoting the adoption of green roofs among homeowners. With this type of roof, you can bring down the consumption of building energy by 0.7% compared to others, and reduce the peak hour demands for energy. As a consequence, you can expect to save $0.23 per square foot of the surface of the roof a year. Their temperature-moderating and energy-efficient abilities are making them a favorite option in the US. 

Choices in green roofs

Industrial buildings and residential homes can benefit from green roofs. Generally, you get two options in green roofing, including intensive and extensive. Both these roofing types can be done using the same materials along with introducing different barriers to stop water from seeping in and roots from damaging the structure. For that, the roof can have a drainage layer that can channel the water out in addition to vegetative and other coatings. As understood, you can expect your green roof to have a combination of these layers with slight variations:

·         Structural support
·         Vapor barrier
·         Thermal insulating layer
·         Drainage Layer
·         Root barrier
·         Filter membrane
·         Growing medium
·         Vegetative bed

It is a typical design of a green roof, but whether or not, all these layers will be there in your roof depends on your budget and the roofer you hire. For an idea, you can get in touch with a professional of a Salt Lake roofing company.

As far as the choices are concerned, intensive and extensive roofs have their functions. The extensive styles are simple. They are made of hardy plants and require about 2 to 4 inches of depth for growing medium. Because they are lightweight, you don't need much structural support for them. The other advantage is you can easily maintain them after they are installed. As per the intensive roofing style goes, this process is a little complex as it reflects any traditional style garden or park. They need structural support to bear the weight. You may have to spend more on this surface and its maintenance after that.
