Blue Roofs

Sustainable Stormwater Solutions for Urban Resilience

Blue Roofs

Flooding is becoming more and more expensive to mitigate in any new or refurbished developments. The cost of failure is catastrophic to local communities.

A blue roof is a specialised roofing system designed to manage storm water by temporarily storing and controlling the release of rainwater, thereby mitigating flooding and reducing strain on urban drainage systems.

Laws and planning guidance focused on flood prevention, urban greening, and energy efficiency are driving councils to seek developments that align with their environmental goals.

  • Effective Storm Water Management

    Blue roofs are designed to temporarily store rainwater on the roof surface, preventing cascading water and avoiding the overloading of drainage systems

  • Rainwater Storage

    Systems efficiently capture and store rainwater for future use

  • Water Quality

    Blue roofs not only store rainwater but also act as natural filters, removing pollutants and contaminants as the water percolates through the roofing layers. This filtration process enhances the quality of rainwater, making it cleaner and safer for various uses.

  • Cooling and Energy Reduction

    Blue roofs enhance cooling by retaining water that evaporates and cools the surrounding air. This process helps to lower building temperatures, thereby reducing energy consumption for air conditioning.

Sustainable Drainage Systems (SuDs)

At national level, the Environment Agency launched a draft of its latest National Flood and Coastal Erosion Risk Management Strategy, a document that is now being revised following consultation. Planning is likely to be centre stage in the strategy, with councils urged to take a more holistic view which includes the use of SuDS.

The core principle of SuDS is to ensure that new developments generate runoff rates similar to those of greenfield sites, managing surface water as close to its origin as feasible. This underscores the appeal of blue roofs.

In Wales, the incorporation of SuDS became compulsory for all new developments over 100 square meters as of January 7, 2019.  In England, while national planning policy recommends the integration of SuDS into major new developments, there are currently no indications that it will be mandated.

Adopting a Greener Ethos

The major harmful emissions from burning LPG are similar to those from other internal combustion engines: Carbon monoxide (CO) Hydrocarbons (HC) Nitrogen oxides (NOx).  1 kg of LPG produce 3 kg of CO 2 .

Reducing Carbon Emissions

The buildings and construction sector stands as the foremost contributor to greenhouse gas emissions, representing an overwhelming 37% of the total global emissions. Given its significant contribution to climate change, addressing emissions within our projects is paramount to achieving sustainability goals and mitigating the impacts of global warming.

 

The built environment, with the construction sector playing a pivotal role, presently accounts for approximately 40% of the UK’s carbon emissions. Moreover, estimates suggest that the construction sector contributes up to 11% of global carbon emissions. This underscores the significant impact of construction activities on carbon footprints, highlighting the urgent need for sustainable practices and innovations within the industry to mitigate climate change.

Flameless Membranes

Mitigating Risk in Construction

Self-Adhesive Roofing Felt requires no flames during installation, enhancing safety and simplifying the application process. It is manufactured from a polyester base with an SBS (Styrene Butadiene Styrene) bitumen coating.

The release film protects the underside of the sheet and can be easily removed during installation, in compliance with BS 8217: 2005, ‘Code of Practice for Reinforced Bitumen Membranes for Roofing.

  • No need for hot works, flames, or additional sealants
  • Self-adhesive properties for safety and ease

Easy and Safe Application

The self-adhesive properties eliminate the need for gas torches, hot works, hot bitumen, and other messy sealants, making installations simpler and less time-consuming.

Single layer or multi-layer systems are ideal for roofing applications such as porches, garages, extensions, and dormer windows. They are also suitable for larger-scale projects due to their easy, no-fire installation.

Whether roller-applied, poured, or sprayed, the adhesives used to create warm roof insulated systems are flexible and feature high bond strengths. As a responsible and diligent roofing company, Tamaris Roofing is committed to ensuring the safest possible installation methods for our employees, clients, and the industry.

 

Adhesives

When a fully built-up system is utilised, primers, activators, torch-free membranes, and insulation adhesives can all be employed. Primers must be suitable for application in any season to ensure an adequate bond that resists wind uplift, with activators available to strengthen this bond.

Advanced self-adhesive technology is used in bitumen membranes for bonding to the substrate. The factory-applied adhesive is protected by a thin release film to prevent sticking inside the roll. During application, the installer uses the peel-back release film to unroll the membrane onto the surface.

The laps are welded using heat, and a visible bitumen bead from the welded laps indicates a secure and robust installation.

 

Net Zero Development

Lifetime emissions from the site should be net zero. Although these sites are generally considered to have a positive impact on emissions reduction because of the production of renewable electricity, there is still the need to ensure that lifetime emissions from the construction, operation and decommissioning of sites are minimised, by for example electrifying the construction and maintenance fleet or by offsetting embedded emissions from the production and construction of the site.

All ancillary buildings onsite should also aim to be net zero. Low carbon construction materials and practices should also minimise the carbon footprint of the development e.g. by local procurement and minimising transport of materials; also supporting the local economy and green growth and seeking to maximise social value benefits throughout the project lifetime in procurement, construction and operation processes. Solar developments should also contribute to the greening of the local economy through increasing green jobs, and green sector skills through upskilling their workforce for example, as these skills will be transferable for both large- and small-scale solar installations. This will also support the Essex Climate Action Commission recommendation to “make Essex a centre of innovation for emerging renewable technologies (e.g. small scale nuclear, & manufacturing of renewables products such as solar tiles)”.
