Living Roof Systems GuaraBROWN Roofing

GuaraDIVERSE Roofing

Because brown roofs usually utilise local soil and spoil to provide the substrate for the roof, the roof will often initially be brown in colour.

However, over time plant species will grow over this substrate and the end result will be a green-coloured roof - albeit one that nature has had a large hand in "designing."

Similar to brown roofs, bio-diverse roofs encourage the growth of local plants and provide a perfect habitat for insects, birds and other local wildlife.

GuaraGREEN Roofing

GuaraINTENSIVE Roofing

Extensive green roofs offer an attractive looking roof finish, but without the need for irrigation or maintenance.

Unlike the Extensive Green Roof, this option will provide an immediate, beautiful roof garden but this comes at a maintenance cost plus the possible need for water irrigation to keep the roof looking as vibrant as when it is first installed.

We offer a range of planting options to compliment the building and its surroundings

This can provide necessary shelter for endangered species that would otherwise be displaced by building works.
