The DIY Guide to Small Scale Green Roofs

Have you ever asked yourself the question – ‘I want to build a green roof…but it all seems so complicated’? If you have, then DIY Green Roof Guide may well be ideal for you, wherever in the world you are thinking of building and whatever type of small scale green roof you are considering.

This online guide is designed to meet the needs of DIY enthusiasts looking to put a green roof on a garden shed or outhouse, as well as builders and landscaper contractors who want to build green roofs.

This website based guide builds on the material and information in our original pdf – ‘The DIY Guide to Green & Living Roofs’ which we published in 2008. That original information has been taken and updated, new and redrawn diagrams made, and multi-media items added. These include short ‘to do’ videos on specific tasksThere are also publicly accessible videos on our youtube channel if you want a quick preview.

A Guide to Green Roofs on Garden Sheds, Extensions, Garages and other Small Scale Building Projects

The DIY Guide aims to take most of the mystery out of how to build a small scale green roof. Whether you want to know how to build one for your shed, garage or house extension, we hope to provide a clear pathway to accomplishing it. This is in contrast to some other websites where the overly technical nature of the supplied information can easily confuse the beginner.

The first edition of this green roof guide was published in order to shed some light on the confused nature of some of the existing material available. Given the large number of emails that both authors were receiving requesting help and information, it was obvious that a DIY guide was both needed and overdue. This latest web based version takes those ideas and principles forward in a form that allows information to be added and updated as necessary.

So this online guide has been developed to:

  • Provide members with the confidence in initiating & taking a project forward
  • Set out the basic principles behind why certain things are needed (or not)
  • Provide simple detailed instructions (down to what nails and screws to use) in a step by step format
  • Supply construction illustrations that make the green roof building process easy.

Why an Online DIY Green Roof Guide rather than another PDF/eBook?

An online resource let’s us be more dynamic. We regularly update the material. We will add more multimedia items such as videos. When new methods are discovered we will add these to the site. It also allows us to provide relevant articles and case studies.

Occasionally there maybe confusion over terms used in the guide. Or perhaps something is not completely clear. If you are struggling with specific details and need further illumination then queries should be addressed via the Members’ Support Form and we will do our best to answer as quickly and accurately as we can.
