What Are the Benefits of a Living Roof?


Are you looking for a way to make your building more environmentally friendly and more beautiful? Then consider installing a living roof. Most people have heard of this innovative architectural feature before, but only some fully understand what it actually entails.

From how they work to why they’re worth investing in, keep reading if you’re curious about living roofs.

What Are Living Roofs?

A living roof is a type of rooftop garden that incorporates vegetation and soil into the design of the building’s structure. The benefits of living roofs vary widely and include improved insulation, reduced energy costs, stormwater management, and enhanced air quality. Living roofs also provide a habitat for local wildlife and can improve the appearance of a building.

Living roofs come in different styles and sizes. The two broad types of living roofs include intensive and extensive roofs.

Intensive vs. Extensive Living Roofs

Intensive living roofs feature large plants, irrigation systems, and sometimes recreational areas like walkways or rooftop patios.

Extensive living roofs are much simpler and lighter than intensive ones and usually contain smaller plants like succulents, grasses, mosses, herbs, or wildflowers. Extensive living roofs do not require irrigation and are easy to install.

Irrespective of the type of living roof chosen, you should consider factors such as weather patterns, access to sunlight, soil quality requirements, maintenance needs, weight capacity of the building’s structure, and local climate conditions.

However, with careful planning and design consideration, living roofs can be an effective way to green any urban space while providing numerous benefits to the environment and your home.

Benefits of Installing a Living Roof

There are many benefits to installing a living roof, including reducing stormwater runoff, improving air quality, and providing insulation. Living roofs can also help to reduce the urban heat island effect and lower energy costs.

  • Reduce Stormwater Runoff – A living roof can help reduce the stormwater that runs off a building and can even help recharge local groundwater supplies.
  • Improve Air Quality – The vegetation on a living roof helps purify the air by producing oxygen and absorbing pollutants like dust, spores, or pollen.
  • Provide Insulation – The vegetation and soil used in a living roof act as natural insulation, enabling you to keep the building cool in summer and warm in winter. This may also help reduce energy costs for heating and cooling.
  • Reduce Urban Heat Island Effect – Living roofs can reduce the urban heat island effect by absorbing sunlight during the day and radiating it out at night, creating a cooling effect on surrounding buildings and streets.

Types of Living Roofs

There are four main types of living roofs: Extended life span roofs, also known as permanent green roofs, are designed to last 75 years or more with little or no maintenance. These roofs are often found in cold climates and require a thicker layer of soil than other living roofs.

Intensive green roofs are similar to gardens and can support different plant life. These roofs are heavier than extended life span or semi-intensive living roofs, so they require a more robust support system. Intensive living roofs are often found in urban areas where space is limited.

Semi-intensive living roofs mix extended life span and intensive green roofs. They require less maintenance than intensive green roofs but more than extended life span rooftops. Semi-intensive living roofs can support different plant life and are often used in moderate-climate regions.

Extensive green roofs have the lightest soil layer and require the most minor maintenance. These rooftops are typical in arid climates where plants don’t need as much water to survive.

Designing a Living Roof

Consider designing a living roof to take your green roof to the next level. A living roof is a roof with vegetation. It creates an added layer of insulation for your building, and it also helps purify the air and can even provide a source of fresh produce.

Designing a living roof is not as difficult as it might seem. The initial step is to select plants that suit the climate and will thrive in the conditions on your roof. Once your plants are picked, prepare the soil and lay down a drainage layer. Then, it’s simply a matter of planting and watering your new living roof!

When designing a living roof, you must ensure the plants you select will not become overgrown or overcrowded. You should also leave enough room for maintenance and repairs if necessary. Finally, since living roofs are exposed to changes in weather, you should use materials resistant to high winds and extreme temperatures.

Once your living roof is complete, you can enjoy the many benefits of organically grown vegetation in your home!

Maintaining a Living Roof

Living roofs are a great way to reduce your carbon footprint and improve your home’s insulation, but it requires some maintenance. Below are crucial tips on keeping your living roof in top condition:

  • Water your living roof regularly, especially during dry spells.
  • Remove debris, like leaves or twigs that may accumulate on the roof.
  • Inspect the roof periodically for signs of damage or wear and tear.
  • If your home area has heavy snow, shovel the snow off your roof regularly to prevent any damage.
  • Prune any overgrown plants or weeds that may be growing on the roof.
  • Keep the soil well drained to avoid waterlogging, which may damage the roots of your plants.
  • Repair any cracked tiles or shingles if necessary.
