Learn from experts on how to build a low cost small green roof

The intention of this online guide is take some of the mystery out of how to build a green roof. Between them Dusty & John have over 50 years experience in designing, planning, building and maintaining green roofs. As they were both getting numerous emails from people wanting to do a green roof but weren’t sure how to go about it they decided to produce the original DIY Guide in 2008. It was evident that the main stumbling block was a lack of confidence and confusion on what layer went where, what were the planting options and what was feasible on a wide range of small structures?

This guide features multimedia features, step by step walkthroughs and useful tips and insights not available in other online resources;

  • Videos of the various stages giving in a detail visual guide to stages of the building of a small-scale green roof:
  • Detailed plant lists for the UK and other countries, regions and biomes
  • Updates on recent innovations particularly about substrates and edge detailing
  • More detailed sketches and drawings to make the stages of the construction much clearer

Measurements are all metric but wherever possible we have converted into US Imperial to save time for purchasers from the US or other countries that use US Imperial.

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 multimedia items added. These include short ‘to do’ videos on specific tasks. There are also publicly accessible videos on our youtube channel if you want a quick preview.
