Green Roof Systems

Green roofs work by bringing together specific components in a system to allow wildflowers to thrive. The primary waterproofing protects your roof - usually timber or concrete - whereas the root barrier stops roots from causing damage. The green roof drainage membrane ensures your plants have enough water but don’t become water-logged. Aluminium edge strips make sure your growing medium and plants remain on the roof and also help with drainage.  

Where can you install a green roof?

Our DIY green roof kit is suitable for 10m² (gently sloped flat or low pitched roofs under 9.5°) as long as some basic design rules are followed. You need to make sure the structure can support the weight of the green roof system. As a rough guide our substrate is 100kg/m² fully saturated at 80mm. Always consult a structural engineer to assess roof load capabilities.

Our green roofs can be installed on:

  • Extensions
  • Sheds
  • Conservatories
  • Garages
  • Cycle shelters
  • Shipping containers

If your green roof is larger than 10m², speak to us and discuss your options.

Shed Green Roof Kit

One of the most popular choices for our products is as a shed green roof kit. It’s an easy, attractive feature that is easy to install on a range of sheds. It can add colour to any garden and transform sheds and outside offices.

Green roof accessories - what else you might need for your green roof:

Primary Waterproofing - Many sheds, outbuildings and structures are already waterproofed sufficiently for a green roof. If you are not confident that your existing roof is suitably waterproofed you will need a liquid roof waterproofer and scrim:

  • Polyshield Liquid Roof Membrane Basecoat & Topcoat - This two-part system (sold separately) is ideal as it’s suitable for both wood and concrete slabs, comes with a 15 year guarantee. It can also be used over existing waterproofing. Larger commercial jobs may want to consider MB2K+
  • Reinforcing Roofing Scrim - reinforce all joints around protrusions with a reliable woven textile scrim

Type of roof - Depending on where you want to install your green roof and the existing structure, you will need a number of accessories. Permagard sell all the accessories you need, but you will need to specify your requirements. Here are some pointers:

Flat roofs - if your flat roof doesn’t have an upstand, lip of more than one inch or front edge you should consider the following to aid with drainage and keeping your growing materials in place: 

Note: Smaller sheds and structures do not always need the above.

Pitched Roof - With pitched roofs without upstands and lips you should consider installing a timber edge that allows for drainage but also contains all of your growing medium. Our systems can still be compatible with pitches over 9.5° but greater consideration is required for retaining the membrane and growing medium/vegetation.
