Sika has launched a complete Green Roof package, supplying both the high performance roof waterproofing system and the green roof system, all backed by its trusted technical and application support.

Specifiers can now go to Sika's roofing experts for the full spectrum of roofing technologies, from hot melt structural waterproofing and reinforced bituminous membranes to single ply and cold-applied liquid membranes, depending on what is best for the project in question, all of which can now be laid with a Sika Green Roof system on top. The new systems are manufactured in the UK and are available in three of the most common green roof types — extensive, intensive and biodiverse.

Sika not only supplies all the materials required for the whole green roofing project, it also lends its invaluable expertise and support throughout. The Sika Roofing team are on hand to aid with initial design, technical calculations and specification through to installation, site inspections and final sign off. Further peace of mind is achieved thanks to Sika’s UK-wide network of Certified Roofing Contractors, all fully trained to deliver high quality results.

With sustainable development a key focus in construction, backed by the government and local authorities, the benefits of a Sika Green Roof cannot be overstated. Multiple studies have shown that green roofing systems can improve air quality, reduce the urban heat island effect, maintain or even increase biodiversity, improve a building’s thermal performance and manage stormwater throughout the year — particularly important in areas of flooding or where Sustainable Drainage Systems (SuDS) are a design consideration.

In addition, green roofs can also reduce noise penetrating through the roof, energy use and building running costs, all while extending the life of the waterproofing underneath. It has been suggested that in some cases that a building with a green roof installed may never need a new roof (Aldred 2019) — a significant consideration when calculating the whole life cycle sustainability of building materials.
