The cost of a Green Roof System?

Wildflower Office Roof Installation

The most popular questions asked…..how much does a green roof cost?

Well unfortunatley there isn’t an excat answer to this question. Why? Because there are many differnent options when installing a green roof system. Each one altering the finished cost.

The cost varibles for a green roof are:

  • Intensive green roof or an extensive green roof? An intensive green roof is alot heavier, consisting of much more vegetation and substrate. Therefore an intensive green roof is more costly than an extensive green roof.
  • Which plant system you would like to use. Sedum roofs are very popular but some people opt for the wildflower biodiverse option. Wildflower roofs are more expensive than sedum roofs due to the range of plants.
  • Will you be installing it yourself or hiring a contractor and architect to design and install your green roof? Doing it yourself can save you a lot of money but you will need to understand the roof requirments to ensure your roof can support the system and how to install in correctly.
  • Green roof accessories….Will you require edge retention trims or a pebble border? All these come at an extra cost.

Green Roof Maintenance Project Hammersmith

As an estimate in the UK the average cost per square meter of extensive green roof system is £50-100, whereas an intensive green roof system is £60-150. Finally there is also ongoing costs to consider for maintenance and repairs. Even though green roofs are low maintenance they still need some care and attention once a year to continue preforming at their best.

With all that said , a green roof system is very cost effective compared to traditional roofing solutions. It offers many benefits to both the environment and living costs such as heating bills.

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.

The organic farm also offers free farm trails, organic café, group tours, glamping in our yurts, educational visits, events, courses, weddings, meeting room space, care farming and volunteering opportunities.

GREEN ROOF FOR LEEDS UNIVERSITY – Sedum Supply Ltd

Sedum Supply Ltd completed the green roof project for Leeds University. This was the very first green roof installation for Leeds University which was installed on its brand new performing arts centre.

Green Roof Leeds University

The new green roof will provide a beautiful feature to the Performing Arts Centre, encouraging the diversity of birds, insects and plant life right in the centre of the city and doing it’s small bit to protect the city from flooding.

The distinctive design concept for the building takes its inspiration from the Victorian Street patterns previously present on site and utilises a strong linear theme on the external facade. The use of dark coloured cladding, set against the adjacent glazed entrance/atrium space, works to create a sense of drama and makes a prominent architectural contribution to the campus and wider city.

Sedum Supply based in Shropshire are green roof specialists who supply and install green roofs across the UK. Sedum green roofs provide many advantages aswell as being much nicer to look at than the traditional waterproofing materials. There are however some much more serious advantages which may help to contribute to our current climate concerns.

Green Roofs help to alleviate flooding. The soft layer of sedum blanket growing on a green roof also has the affect of absorbing sound, quietening noisy urban environments and reducing sound pollution within a building. It also increases the thermal insulation of a property making it warmer in winter, cooler in summer and reducing energy costs.

A very important environmental benefit is that green roofs encourage biodiversity of an area. Green roofs can help compensate for the loss of green surfaces, sacrificed to building developments.
