Frequently Asked Questions

There are many benefits to installing a green roof. They reduce storm-water runoff to reduce the risk of flooding in drainage basins; they reduce energy use of heating and air-conditioning by insulating the roofs and keeping the building warmer in winter and cooler in summer; a roof’s lifespan is increased by reducing heat fluctuations and UV exposure which degrades roof membranes; they help to mitigate the effects of global warming; the urban heat island effect is lessened in large cities; air and water quality is improved; they act as noise insulation and can reduce noise transfer by 8 decibels; they increase biodiversity and reclaim land lost by development and urban sprawl; and of course, they look beautiful!

In most cases where green roofs are installed on existing buildings, planning permission is not required. However, it is always advisable when making any kind of alteration to a building to contact your local planning department.

Green roofs can be created on flat or pitched roofs. Ideally, a green roof will go on a slope up to 10° but if it's on a slope over 20°, make sure you have a frame to stop the green roof from slipping. First, a layer of waterproofing needs to be added to your shed or garage.

Green roofs last 40 years or more and attract wildlife such as birds, bees and spiders.

In addition to thermal insulation, a green roof also has a sound-insulating effect. The combination of substrate, plants and the embedded air in the green roof system provide good sound insulation. Sound waves are absorbed and reflected.

Yes. Green Roofs are 'Low-Maintenance' not 'No-Maintenance'. Green roof maintenance is generally a very simple process. They are designed so that they will not require endless hours keeping them looking at their best.

Under normal circumstances the roof should not need regular watering. Sedum is used because it is drought resistant and very hardy. However, live material must be irrigated immediately following installation. This irrigation must continue in the first few months following installation and again in especially hot and dry periods.

Yes. Green roofs can be designed to fit around solar panels or the panels can fit on top of the roof. This can not only increase the efficiency of the solar panels, but the shade created by the solar panels can increase biodiversity of the underlying green roof.

BREEAM stands for Building Research Establishment Environmental Assessment Method and essentially sets the standard for the best practice in design for large scale developments. The addition of a green roof can increase the building’s BREEAM rating by making the building more environmentally friendly.
