Green Roof

A green roof (or living roof) is a roof covered with plants and vegetation growing over a waterproofing membrane.

In some cases it also includes additional layers such as a irrigation and root barrier & drainage systems.

(The word "green" refers to environmentalism and not the colour green, as with green roof tiles or roof shingles).

Depending on the use a wide variety of plants can be used, especially rock dwelling plants and succulent types which retain moisture and generally thrive on a living roof.

These include: Sedums, Sempervivum, Arabis, Campanula, Dianthus, Saxifrages and a range of grasses.

Our flamingo house features a green roof to help reduce heat loss and energy consumption. Click on the image below for a closer look.
