Green Roofing is becoming more and more mainstream as architects, garden designers, property developers and householders work harder to improve eco-efficiency and combat the effects of climate change. There are a plethora of benefits associated with a green roof, not least that it creates a real talking point. Click here to read our article about the benefits of green roofing.
Enviromat’s green roof kit for flat roofs includes the main ingredients needed to transform a dull, roof into an inspirational layer of flowering plants. Three, easily installed layers to create an almost self-sufficient system.
First of all, is a root barrier to make sure the plants cannot damage your waterproofing.
Next comes a layer of specially engineered drainage mat. Sedums dislike wet conditions. This matting ensures that excess water is wicked away from the roots.
Last but by no means least is your Enviromat. A pre-grown mat consisting of a carrier fleece for easy handling, specially formulated growing medium and of course, sedum plants. Plant coverage is at least 80% and usually more. That means from the moment your Enviromat is unrolled, your roof is fully planted.
We’re very proud of Enviromat and hope you’ll like it as much as we do. It’s grown out of doors, in the UK so has a low carbon footprint and is well adapted to our climate. There’s a lovely mix of plant species and it flowers merrily for up to 9 months of the year.
The patented carrier fleece contains recycled materials that hold the growing permanently medium in place. That means minimal substrate loss during the handling process, less fiddling about and less slippage once the blankets are in situ.
Sedums plants are very easy to care for. Being succulent plants, they cope well with drought conditions and once established will only need a very occasional watering extremely dry weather. Feeding is important though. Please be sure to apply a specialist sedum feed every spring.
Your roof must have a load bearing capacity of at least 120Kg per square metre. (This includes ‘live loading’ such as a person walking on the roof for maintenance).
The Enviromat green roof buildup is not waterproofing. Please ensure that your roof is fully waterproofed before adding your Sedum Green Roof Kit for Flat Roofs. Once the layers are in place it becomes difficult (and expensive!) to deal with issues.
Drainage should be efficient. If rainwater sits in puddles on your roof for any length of time, please seek professional advice before adding your green roof buildup.
Every green roof needs an edging to protect against wind uplift and dried out plants. You can purchase proprietary green roof edging, you can make it yourself or you can take advantage of an existing roof upstand. If you need advice on how to do this, please email the Turfonline Team.
