Green Roofs: How to install an instant Sedum Roof (Video)

Green roofs have many benefits both environmental and aesthetic, but sometimes the process of designing and installing even a simple extensive green roof can put off small contractors and leave architects without a workable solution, particularly in smaller projects.

Now SIG Design and Technology has launched an extensive green roof system that can be installed over most waterproofing roofing systems and doesn’t need specialist know-how or tools.

LiveRoof® Lite is the roofer-friendly modular green roof system from Blackdown Green Roofs and is available exclusively through SIG Design and Technology.

Simple Green Roof Installation

The roof can be installed in four easy steps, providing an instant, extensive sedum roof on the day of installation, because it is delivered with 90-95% mature sedum plant cover in self contained fully complete trays including drainage layer, filter layer and planting.

Preparation is simple. Once you have confirmed the roof is suitable*, simply sweep off, clean down and lay any necessary separation layer.

LiveRoof Lite Green Roof Installation Step1

Step 1:

Loose lay the interlocking LiveRoof Lite modules onto the prepared roof surface, placing them neatly together to form a grid. The trays are specially designed with lips on two sides and instructions on the stickers guide you through the installation process.
