6.5m School building with Anthracite grey windows and door- sedum blanket on the roof

The beauty of a sedum roof is that is relatively low maintenance. Although you may need to consider some essential tasks if you want your green roof to flourish and attract wildlife.    We recommend you access your roof 3 times a year in Spring, Summer and Autumn to carry out few maintenance tasks.

Clear away debris

If any fallen leaves, rubbish or dead plants then you need to remove these items, especially from the drip system at the edge of the roof panels. It is very important that sedum plants have access to 100% sunlight.

Water your Roof

Your roof may be low maintenance but every so often it does need a drink! If you are experiencing a drought or lucky enough to be in heatwave then please ensure you water your roof every so often; although Sedum is very hardy and rarely fails, a heatwave and no water means you may end up with droopy, dull and unhappy plants. 

Feed your roof

Please ensure you feed you sedum roof when we have hot weather as your plants begin to grow.

We recommend using Enviromat Natural Green Roof Feed at a rate of 85gs per m2. (Remember this must be watered with 24hrs of application). This is a slow release formula and contains all the nutrients that a sedum roof needs.

Check your roof

If there are any areas that are large than A4 piece of paper where the vegetation has disappeared, then you will need to break some small pieces of existing plants and press them into the growing medium on the bare area. This is provided that the air temperature is above 6 degrees and you are not experiencing a drought. Smaller areas with often just re-vegetate themselves once the plants have been fed and started their growth spurt.

Sedum roof during Autumn and Winter

Please remove all fallen leaves and twigs within 2 weeks as these can suffocate your plants. Unblock any surrounding gutters / ensure all the draining outlets are working well. Please do not feed the sedum roof during the winter.
