Green roofs are essentially the tops of buildings doubling as a garden or vegetation. Based on the type of garden roof you create, the plants might include drainage or modular layers. However, all green roofs also function as insulations, waterproofing the house and preserving the indoor temperature alongside keeping the structure undamaged and safe. For excellent warm roofs, head over to ArchiPro.
A green roof is a vegetation layer and waterproofing system installed on a slightly sloped or flat surface. They are also known as vegetative, eco, or garden roofs. Typically a green roof falls into three core categories:
Hence, the more components that are added to the vegetation, the more this definition changes. This involves adding waterproofing, drainage system, filter cloth, root repellent system, or other components to the green roof. Additionally, they could either be part of the same ecosystem or be built in a way where each element is installed separately. As a result, garden roofs provide a diverse range of private and public benefits and are used globally.
Green roof systems have multiple benefits at ecological, societal, and economic levels. Here are the most important ones:
A nature roof or green roof absorbs rainwater by creating a layer of plants, drainage, and substrate. This keeps any excess seepage from entering the house. Moreover, groundwater stabilizes due to this process, the sewage system’s peak load is reduced, and flood risk is minimized.
Plants in nature roof filter particles from the air and convert carbon dioxide to oxygen. Having a green roof contributes to air purification.
Plants are excellent absorbers of sunlight; they absorb 50% and reflect the 30%. This helps in creating a more pleasant and cooler atmosphere.
Grass roofs act as a sound barrier to the building. They absorb sound and provide a quieter environment, both outside and inside the building.
A garden roof can also be used with TPO membranes, protecting the roof from external factors like rain, sun, wind, and temperature fluctuation. This increases the life span of the roof by a lot.
Green roofs offer a lot of variety in how they are applied because they can be used on industrial, commercial, and residential structures.
Furthermore, they can be installed into a newly constructed building or added to existing buildings during roofing or renovation.
Ideally, green roofs are laid on a low angle or flat rooftops; however, some have been installed on pitched slopes with specific features to ensure plant survival.
As green roofs are made on top of a refined surface, their layers must follow a pattern to ensure adhesion:
As a result of this meticulous layering, green roofs are impeccable at protecting roof foundations, such as mastic asphalt.
There are three different types of green roofs, and they are categorized based on how thorough their application is:
These types of green roofs are designed for their environmental efficiency. Some of the features of extensive living roof systems are:
Intensive green roofs are the standard rooftop gardens. However, they differ from the extensive ones in how they are fully landscaped. Some of their prevalent features are:
As the name suggests, they contain both elements of intensive and extensive systems. They are usually set up as a reasonable solution to green roofing. As a result, homeowners get a diverse vegetation plantation on a manageable maintenance budget.
A green roof can be installed in five simple steps. However, the following steps are for an extensive green roof. Intensive green roof construction is similar, but it differs according to the owner’s preference.
The roof deck, whether it is screed or concrete, needs to be waterproofed. Some roofs already have a waterproof layer, but butyl rubber membranes are a perfect choice if they do not. However, EPDM membranes are widely used in low slope roofing.
Membrane roofing is essential to create an airtight covering protecting the interior of the building and creating a root barrier.
After placing the root barrier, the green roof drainage membrane can be rolled across the length of the roof.
Now comes the part of adding substrate, which is common in organic material and aggregate combination. Spread it evenly across the roof as per required depth.
Plant the green roof seed or plants.
Nature roofs are perfect for enhancing the look of an urban neighborhood home or one out in the suburbs. With excellent benefits, green roofs provide a cost-effective and more natural aura.
