Through the natural process of photosynthesis a living roof can; remove CO₂ and airborne pollutants to storage as biomass, improve acoustic & thermal insulation, reduce flood risk, urban heat build up and energy bills !₁

We offer DIY kits or a fully project managed installation of a living roof system to suit your needs. ₁.

EXTENSIVE (Sedum) ROOF COVERING

Extensive green roofs have low management requirements.  Plants, such as mosses, sedums and grasses that require little or no attention are used to achieve an attractive, natural roof covering appearance that is self-sustaining.  Grown on a thin layer of soil 80-150mm deep, they are lightweight systems of up to 75-120kg/m², typically supplied as a sedum 'mat' or 'carpet' (as illustrated), that is fitted on to new and existing roofs.

Extensive green roofs are usually installed for their visual appeal and to reduce the environmental impact of the building, to provide solar shading and space cooling in summer, to absorb rainwater and help suppress water runoff and flooding, to create a natural habitat for flora and fauna, and for their ability to absorb CO₂.

For even greater environmental benefits consider incorporating  solar lighting tubes with a sedum roof fitting.

BIO-DIVERSE ROOF GARDENS

Extensive green roofs can be subdivided into different systems dependent upon the plant species used, the substrate composition and depth and what ecological benefit is required.  

As well as Sedums, Mosses and grasses a wide range of hardy perennials, low growing shrubs and evergreens can thrive.

They will require some feeding, could require irrigation and a soil or substrate depth of between 150-250mm which means weights of up to 250kg/m² should be expected, hence these systems could require a structural survey with possible modifications to the building design and/or strengthening of existing roof.

 

INTENSIVE ROOF GARDENS

Intensive green roofs are like any garden that provides space for people to use, it's just that they are built on the roof of a building structure. They are so called because they require 'intensive' management, usually require a thick layer of soil and will require artificial irrigation.

Plants selected can be small, (grassed lawns for example), or large, (trees and walls are not uncommon). Soil depth and roof conditions required to support such a design needs to be designed accordingly.

At up to half a tonne/m² intensive roof gardens are heavy and will require serious consideration to structural design of the roof and its supporting structure whether for new or existing buildings.

 

LIVING ROOF IRRIGATION  SYSTEMS

The StormBank™ Garden rainwater harvesting system collects and stores water (ideally from the roof of adjacent building), which can be used for irrigation of your gardens.

A pumped water supply is piped from the tank to a connection at the surface ready for your garden hose or sprinkler.  The system can be operated manually or on an automatic timed control valve. 

Systems are available from 1000-6000 litre capacity. The tank is of high strength, ribbed, low density polyethylene, rota-moulded in a single piece to guarantee against cracks and leaks and are covered by a 15 year material guarantee, when installed in accordance with the manufacturers recommendations.
