Different Types of Green Roofs

Now, you know what is a green roof and what does it do for your home. It’s time to discuss the two types of green roofs.

The only thing common about these two green roof types is both use a layering system. The layers house the soil and provide proper water management to avoid ponding and other dangers to the roof of any property.

Intensive

Deriving its function from its name, intensive green roofs will hold about 150 pounds of vegetation, plants, and other greenery per square foot. Indeed, it is similar to having a forest and even an animal reserve on top of your home (that’s exaggerating it).

However, intensive roofs allow property owners to choose the plants, flowers, and other vegetation to sculpt the utmost aesthetic they want for their roofs. If the joists of the roof will support the new green roof and its staggering additional weight, property owners have the ability to introduce a park-style green roof on top of their homes.

Intensive roofs look like they’re gardens or parks on top of your property.

Extensive

On the other hand, extensive green roofs are less manageable due to the smaller space and fewer plant variations. You only need to provide annual maintenance for it. In fact, doing so will be a pain to homeowners due to the smaller space.

Benefits of Green Roofing

Both commercial and residential homeowners enjoy several advantages in owning a green roof. Given what is green roofing and what does it do, it contributes benefits not just to the property owner, but to the community they belong in as a whole.

The emulated layered soil on top of green roofs absorbs 50% of rainwater. Green roofs help reduce adding duress against local sewer systems. In fact, rains allow property owners with green roofs to have free garden watering in the process.

Extensive Green Roofing

Both intensive and extensive green roofs help reduce and improve stormwater management.

Introduces Better Property Cooling

Commercial and residential properties in urban locations reduce the general heat of the structure with green roofs. In this way, they earn additional tax benefits. States across the country encourage the building of green roofs because of its lower carbon footprint and natural aesthetic.

Improve Smog and Dust Reduction

Air pollution is the biggest threat to the world today. In urban locations across the world, smog descends towards the city. Green roofing helps improve smog and dust reduction. Plants use carbon dioxide and other dangerous pollutants to create their food. In the process, they break down the pollutant and inject oxygen as a byproduct.

Reduce Noise Pollution

What is a green roof and what does it do? You’d never imagine it capable of reducing noise pollution!

The thick layers of soil for both intensive and extensive green roofs undeniably reduce noise for any property. Soundproofing principles involve using different layers of fiberboard and insulating material such as discarded pillows and mattresses. This slows down soundwave transference. Soil functions in the same way as insulated material. It reduces the vibrations entering the home, improving property noise reduction.

Improve Utility Bills

The thick mat and layering material to ensure soil does not permeate through the underlayment improves property insulation. As a matter of fact, the cooling soil creates an airtight seal for any property and cools the membrane in the process. This allows property owners to reduce their utility bills by reducing HVAC usage.
