Green Roof Systems

Green roofs work by bringing together specific components in a system to allow wildflowers or sedum 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. 

One of the biggest benefits to installing our DIY green roof, is the ability to regualte the internal temperature of the structure. Garden offices in particular can become unbearable through the summer months. The simple installation of our kit can keep the office nice and cool and comfortable, without the need for expensive air conditioning systems.

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. 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

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. It has a life expectancy of 10 years but this is likely to be extended as the green roof protects it from UV light and weather. It can also be used over existing waterproofing. Larger commercial jobs may want to consider MB2K+
  • 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 green roof 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: 

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.

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.
