FAQ

It is possible to put a Green Roof System on many types of pitched roofs.  If the pitch is quite steep we have to place batons and drainage supports etc. to stabilise the Sedum mats or blankets. Sedum Green Roof can install all this for you, or simply advise you. Just give us a call and we can explain all the different options available. Sedum can be used as a Sedum shed roof, Sedum garage roof or many types of Green Roof. Our S-Pod or modular trays (Sedum trays) are very easy to use and there is little Sedum green roof maintenance. We can provide many Sedum species on your green roof and provide services such as Sedum green roof maintenance.

No, if you use Sedum then the plants come in a variety of shades from whites to yellow, from purples to blues, pinks and deep reds.  When the flowers are blooming there can be a dazzling array of colour.  Sedum Green Roof can supply colour schemes to suit your needs. The colours change according to the seasons and in winter beautiful hues of reds and browns as well as green can be seen, keeping your roof lush and colourful all year round.

Yes of course! To put a Green Roof on an existing building it must firstly be checked to make sure it is load baring and can take the weight of the Sedum Green Roof System.  All roofs must be water tight. Using our S-Pod modular tray system the roof does not require layers of substrate and drainage as it is incorporated into the Tray.  The team at Sedum Green Roof will advise you.

Most definitely not.  Garden soil or compost is completely wrong as it is too heavy, gets too heavily saturated, can be infested with weeds and I could go on!  Sedum does not like too rich a soil so Sedum Green Roof, with the help of experienced horticulturists, have developed our own substrate which we can supply.  The substrate we supply is far lighter and is made up of mineral components with very little organic matter, all the soil comes sterilised. The substrate is designed to allow the exact water retention and drainage to fasciliate the perfect Green Roof.

Sedum is very hardy and requires little maintenance.  However some fertiliser thrown on the roof once or twice a year can help.   If not we can advise you and tell you what to do but it really isn’t very much!

Sedum is a succulent and does not like wet environments but in very dry periods we do advise to water little and often as it is still a living plant. Its best to water early in the morning or late at night to avoid sunlight hours as this can scorch the sedum.

If the spring growing season is very dry then once a week watering will help its growth for that year.
