+44 (0)1268 777871Attenu8® the complete green roof solution – design, waterproofing, insulation, blue roof and bio solar - all in one package
The complete green roof solution - everything in one package. Choose Proteus and you get a fully integrated system, including a choice of BBA-certified waterproof membranes, all accredited to last the lifetime of your building once covered.
Full design responsibility from first concept to final delivery:
When you choose Proteus, you get a partner who takes ownership of the entire process. From the initial concept and specification to installation by our network of approved contractors, we ensure every element works together seamlessly. This end-to-end responsibility eliminates gaps between suppliers, reduces risk and guarantees the finished roof performs exactly as designed for the lifetime of the building.
Insulation designed specifically for your building’s thermal demands:
Every building has its own thermal profile and Proteus design your roof insulation to match it. The Green Roof is included in the thermal calculation as a thermal element of the new roof or building calculation. By integrating insulation into the roof build-up from the start, we ensure full compliance with building regulations while supporting the overall sustainable goals of your project.
Stormwater control via our patented Attenu8 Blue Roof system: When rainfall is intense, your roof can become part of the solution. Our Attenu8 Blue Roof technology manages stormwater at source, controlling the flow into drainage systems to mitigate flooding and protect infrastructure. Attenu8 provides predictable performance without compromising the waterproofing beneath. If stormwater management is a requirement for your development, this is a proven answer.
A Bio Solar option for cooler, more efficient panels: The Proteus Bio Solar system combines renewable energy with the biodiversity benefits of a green roof. The planted surface keeps the solar panels cooler, which boosts their efficiency and extends their lifespan. Panels are held in place by the weight of the green roof build-up - removing the need to penetrate the waterproof membrane and protecting the integrity of the roof for decades to come.
Documented environmental benefits
It is widely reported that green roof systems deliver numerous environmental advantages, making them a popular choice for architecture. Green roofs are known to contribute to better air quality, support biodiversity and help mitigate the urban heat island effect.
Improved air quality
Green roofs help reduce pollution by filtering air pollutants and releasing oxygen, creating cleaner air. The integration of sedum and other vegetation further improves air quality, fostering a healthier urban environment.
Stormwater management and drainage
One advantage of green roof systems is their ability to manage stormwater effectively. The substrate and vegetation help absorb excess rainwater, reducing runoff and lowering the risk of flooding.
Habitat creation
Green roof solutions support urban wildlife by providing a habitat for birds, bees and insects and provide valuable habitats for a variety of other urban wildlife.
Choosing the right green roof
What type will you choose – an extensive or an intensive green roof? The right choice will depend on your building’s structural capacity and the intended use of the roof space. Lightweight systems deliver benefits with minimal upkeep. A green roof can also consist of landscaped gardens designed for people to enjoy. Proteus can help you decide.
Extensive Green Roofs – Ideal for projects where weight and maintenance need to be kept to a minimum, extensive green roofs use a shallow substrate layer planted with hardy, low-maintenance vegetation such as sedums and wildflowers. They are lightweight, making them perfect for refurbishment projects or buildings with limited load-bearing capacity.
Despite their simplicity, they still deliver effective thermal insulation, reduce rainwater run-off and contribute to urban biodiversity. Proteus can guide you through the selection of planting schemes, waterproofing systems and drainage layers to ensure your extensive green roof performs exactly as required.
Intensive Green Roofs – Often referred to as ‘roof gardens’, intensive green roofs feature deeper substrate layers that can support a wide variety of plants, including shrubs and even small trees. They offer the scope to create accessible landscaped spaces, enhancing the building’s amenity value and providing biodiversity gains.
Because these roofs can be designed for recreational use, they require careful planning around structural load, irrigation and ongoing maintenance. Our technical team can work with you to design an intensive system that meets your project’s structural constraints.
Shared Benefits – Whether you opt for an extensive or intensive system, both green roof types create an additional thermal barrier, moderating temperature fluctuations and improving a building’s overall energy efficiency. In summer, they reduce heat gain, while in winter, they help retain warmth – lowering energy costs and enhancing occupant comfort.
Why it has to be Proteus
When you choose a Proteus Green Roof, you’re not just getting a roof – you are investing in a complete system designed to perform for the life of your building. Every layer, from the waterproof membrane to the final planting, is specified, supplied and supported by us, with the option to integrate our patented Attenu8 stormwater control and Bio Solar technology. Backed by full design responsibility and installation through our approved contractor network, we deliver certainty, compliance and lasting value. If your next project demands a green roof that needs to stand the test of time, Proteus is the partner who can make it happen.

FAQs
-
What is a green roof?
A green roof is a roof that is partially or completely covered with vegetation and a growing medium. Green roofs can be installed on new or existing buildings, and they offer a wide range of benefits, including:
- Green roofs can help to insulate buildings, reducing the need for heating and cooling
- Green roofs help to filter pollutants from the air
- Green roofs absorb rainwater, reducing stormwater runoff and flooding
- Green roofs provide habitat for birds, insects, and other wildlife
- Green roofs help to protect roofs from the elements
-
Are green roofs good for the environment?
Yes, green roofs contribute positively to the environment. They help to improve air quality, reduce stormwater runoff and increase biodiversity.
-
Can a green roof be installed on my existing building?
Yes, a green roof can be installed on most existing buildings. However, it is important to have your roof inspected by a qualified professional to ensure that it can support the weight of a green roof.
-
How much maintenance does a green roof require?
Extensive green roofs typically require low maintenance, typically only needing to be watered and inspected once or twice a year. Intensive green roofs require more maintenance, similar to a traditional garden.
-
What are the benefits of having a green roof?
• The benefits to a green roof are:
• They can help to insulate buildings, reducing the need for heating and cooling.
• They help to filter pollutants from the air
• Green roofs absorb rainwater, reducing stormwater runoff and flooding. This can help to protect property and infrastructure from damage
• They provide habitat for birds, insects, and other wildlife
• Green roofs aid in shielding roofs from the elements
-
What are the different types of green roofs?
There are two main types of green roofs: extensive and intensive.
Extensive green roofs consist of a shallow layer of growing medium and drought-tolerant plants.
Intensive green roofs are heavier and can support a wider variety of plants, including trees and shrubs.
