Many people are talking about the issue of climate change and how we as individuals can do something to reduce our carbon footprint in some way. One of the quite innovative ways that people are considering is installing a green roof. The term is used to describe a roof that is seeded, and which grows some variety of grass on its surface and sometimes meadow flowers too. A green roof is more easily installed on new builds in conservation areas but can be introduced on any suitable roof area. They can more commonly be seen on flat roofs, but it is possible to have a seeded green roof on one with a low pitch.
One of the first things to check before you embark on this project is to establish whether there are any council permissions that need to be sought beforehand. Due to the weight of the soil layer on an existing roof structure it could be that the property will need to be checked structurally by a building surveyor before work can proceed.
As long as the relevant authorities are happy for you to install the green roof the next decision will be who to employ to conduct the work. Most people get three quotes which is common practice and ask for references from past clients. Viewing other projects that the company have completed is also advisable.
