Green roofs perform a vital role in helping cities adapt to the effects of climate change by reducing the need for artificial cooling in hot weather. They reduce rainwater run-off and provide a range of habitats for wildlife. However, green roofs can only provide these environmental benefits if they are properly designed and installed by a specialist Green Roofing Contractor.

Green Roofing Systems Offer Extended Roof Life

A green roof system will protect the waterproofing membrane from weather, damaging ultra violet light and mechanical damage. The life expectancy of a green roof can be almost doubled! Therefore you can expect a good quality root resisting waterproofing system to last up to 60 years rather than the usual 30 years. This cost benefit alone far outweighs the cost of installing and maintaining a green roof system.

Save Energy and recover the cost of your Green Roof in 2 – 3 years

Our highly experienced team of green roofing contractors know that green roofs offer significant thermal insulation benefits. A green roof has the ability to cool buildings in the summer and insulate them during the winter. Green roofs can contribute significantly to savings in heating costs. An industrial plant in Frankfurt, which had a green roof installed, recovered the cost of the green roof in 2-3 years. This was through savings in both heating and cooling costs including the costs associated with maintaining / replacing the required heating and cooling equipment. A conversation with a building services manager in London uncovered that the application of a retrofitted green roof on a building had reduced the need for cooling / heating of industrial plant in the floor beneath. Since the green roof has been installed cooling and heating fans have not been used. It was estimated that about 25.9 MW per year was being saved. Based on electricity rates current at that time, the saving amounted to approximately £4,300 per annum.

Benefit Drainage with Green Roof Installation

Surface water drainage capacity can be significantly reduced
. Green roof installation could reduce the number of drainage outlets offering a potential saving for developers. It has been pointed out that these benefits are unlikely to factor in, as roof drainage costs are traditionally costed separately.
However, depending on the size of the roof and the height of the building, the potential to reduce the number of drainage outlets at both roof level and ground level could significantly off set the cost of a green roof.

Sound Insulation and Noise Reduction

Reduce the noise level by up to 50 dB.  The combination of soil, plants and trapped layers of air within green roof systems can act as a sound insulation barrier. Sound waves are absorbed, reflected or deflected. The growing medium in a green roof will help to block lower sound frequencies whilst the plants block higher frequencies. The amount of sound insulation is dependent on the system used and the substrate depth. A green roof with a 12cm substrate layer can reduce sound by 40dB and one of 20cm by 46 – 50dB.

Extensive and Intensive Green Roofing Systems

Intensive green roofs are the heavy-weights of the green roof world. In essence, they are parks or gardens on roofs. Because these types of intensive green roofs have deeper soils, they are heavier than extensive green roofs. Just as a park or lawn will require regular maintenance, these green roof’s will also require maintaining.

Extensive Green Roofs are designed to offer a low maintenance, lightweight system with no general access. Typically they would consist of a thin layer of substrate growing medium to keep weight and depth to a minimum. Extensive green roofs are delivered for a variety of reasons. The most popular being for biodiversity and meeting a Biodiversity Action Plan.

Reduce the likelihood of local flooding

Green roofs store rainwater in the plants and growing mediums and evaporate water into the atmosphere. The amount of water that is stored on a green roof and subsequently evaporates is dependent on the growing medium, its depth and the type of plants used. In summer green roofs can retain 70 – 80% of rainfall and in winter they retain between 25 – 40%. Green roofs, therefore, reduce the impact of run off on the storm water drainage system, and reduce the likelihood of local flooding.

    I am pleased to recommend Ian's team at Acclaim Contracts for roofing work. I have completed a number of successful projects with Ian and his team and found their quality of work to be excellent. With most projects being in sensitive education settings, communication with the client is critical. Ian always takes a strong personal interest in projects which helps everyone.

    I was really pleased with the company. The job ran really smoothly. Nas was our main line of communication and he was very professional and helpful. The job was completed on time, and there was minimum disruption to the school despite it being such a big job.

    In terms of after-service, the company have responded very promptly to any queries / snagging issues and resolved them immediately. I think the service given by Acclaim has really been good – particularly when I compare it to the experiences that colleague Heads have had having similar jobs done by different firms.
