Benefits of choosing a Green Roof

Green Roof Benefits

Green Roofs – The benefits

Green Roof Benefits

Green Roof Benefits:

In recent years we have seen green roofs poping up everywhere, from rural locations to our cities. Green roofs are becoming a popular choice over more traditional methods of roofing.

Why? Because more people are realising the many benefits they offer as well as being well supported by Goverment projects. With global warming becoming a worrying issue for the world the UK Goverment has been working towards stringent EU targets.

Green roofs inprove the aesthetic appeal of built up city areas and buildings situated in our rural countryside. They look much nicer than the plain greys & blacks of traditional building materials.

Roof Life Expectancy

Roofs need to withstand a variety of harsh and testing weather conditions in the UK. Our unpreditible weather can serverely damage commerical and residential roofs. Green roof systems are planted with sedum or wildflower, which both survive easily in bad weather conditions. The planted vegetation also provides a protective barrier to the waterproof membrane.

Green roofs offer a life expectancy 2-3 times longer than traditional roofing materials when maintaned correctly.

Flood Control

Flooding in the UK is on the rise due to Global Warming and the increase of buildings and developments. On average 75% of rainfall is running off causing excesss flooding. Green roofs provide a substainable drainage system. The vegetation and substrate can hold on average 60 percent of rainfall. A considerable amount more than conventional roofs that on average hold only 27 percent.

A green roof system will release water back into the environment slowly and naturally.

 The Environment

Environmentally friendly and substainable. The plants of a green roof system help improve air quality and decrease carbon dioxide. Wildflife is also effected by polluted air and the decreasing areas available for habitats. The green roof systems offer a healthy habitat for a variety of wildlife including birds, bees, butterflies  and many more.

Thermal Performance

One of the most popular benefits of a green roof system in its ability to boost thermal performance of any building. They provide great installation for the roof, preventing heat escaping in the winter and in return stopping heat from penetrating inside in the hot summer weather. The sedum and wildflower plants also have the ability to absorb the Sun’s rays, decreasing the amount of heat on the roof.

Scilly Islands EPDM Roofing Project – Peninnis Farm Lodges

EPDM Roofing Project

New Lodges get EPDM Rubber Roofing Installed

Sedum Supply Ltd has been busy installing the EPDM Rubber Roofing onto 7 new lodges at Peninnis Farm.

The project is well underway with the installation of EPDM roofing. The new bespoke lodges are designed to unsure a unique holiday experience which are situated in St Mary’s, Isles of Scilly. As a matter of fact the lodges are named after the islands pilot gigs.

Furthermore the project was subcontracted to Sedum Supply Ltd by Pod Living Ltd to complete the EPDM waterproof membrane for the 7 roofs. The project has not only been exciting but challenging at times. Access to the islands is difficult making shipping materials costly and time consuming however our experienced team has been working hard to complete the project quickly and to a high standard. Here at Sedum Supply Ltd like to say ‘No project is to difficult or to big.’

As the project developed it was desired that something needed to be designed to fit onto the EPDM rubber which would allow the roof cladding to be safely secured to it without compromising the EPDM waterproof layer. Our design team quickly began work on designing bespoke brackets for each roof to allow the installation of the cladding and shipped these over to the Island for installation. Sedum Supply is experience in designing bespoke fittings for roofs to provide the best installation solution.


EPDM Rubber



The project consisted on 980 square meters of Firestone EPDM Rubber Membrane. Our experienced team have installed the EPDM membrane as a waterproof layer before the finishing roof cladding is installed to complete the desired log cabin look.

EPDM is a highly durable rubber roofing membrane which is used and recommended worldwide. It provides a watertight and extremely durable roofing solution for small and large commercial projects. Also it has an incredible life expectancy of 50 years, which is considerable more than traditional roofing materials.

EPDM Roofing for Farm Lodges












Bio Diverse Green Roof for Organic Farm

Bio Diverse Green Roofs

Sedum Supply Ltd supplied and installed the bio diverse green roof for Fordhall Organic Farm in Market Drayton, Shropshire. A single ply waterproofing system was used on an existing roof deck and a bio diverse planted roof system installed to create a beautiful substainable roof system.

The Wildflower green roof installation was part of a full renovation and extension to the old dairy. Which would provide new offices, a classroom, tearoom, butchery and farm shop. The green roof was planted with carefully selected wildflowers and grasses native to the local area as requested by the client.

The client, Shingler Homes, said: “Sedum Supply have been putting the gravel base onto our green roof. This substrate will hold a beautiful bio diverse roof, which all the local wildlife will be able to take advantage of throughout the year.”

The new bio diverse green roof will provide many benefits to both, Fordhall Organic Farm and the environment. Wildlife will have a new habitat, stormwater runoff will be reduced as well as noise, pollution and energy costs. The beautiful wildflower roof can be appreicated 6 days of the week as they are open all year round to the public.
