Using Green Roofs To Enhance The Local Environment

January 28th, 2020

Green roofs provide possibly the easiest and most effective methods of helping to bring nature into the cities.

They are a useful and realistic way to improve the aesthetics of often very stark and ugly flat roofs.

Enhancing the Local Environment

Finding ways to improve the local environment is high on the to-do list of cities throughout the UK and this is the number one priority of the green roof division at Wallbarn.

We work closely with both our clients and landscape architects during all stages of the planning process to ensure that we can install the most appropriate and diverse green wall possible, such as we did at the Victoria Drive Care Home at Wimbledon.

Our green roofs designed and constructed to complement the existing architecture of the building in question with the goal of being able to capture the imagination of occupants and visitors for years to come.

We offer our customers the opportunity to benefit from the wide-ranging benefits offered by this easy to install the modular green roof system, the M-TRAY®.

While a traditional roof is designed to keep water off and heat away, green roof technology is designed to do something a little different.

A green roof strategy could help cut the negative impact caused by severe storms and flooding, studies have shown.

Effective Protection Against Excess Rainfall

A study by the United States Environmental Protection Agency has taken a closer look at the way green roofs can effectively combat the threat posed by annual rainfall.

“Results indicate that the green roofs are capable of removing 50% of the annual rainfall volume from a roof through retention and evapotranspiration. Rainfall not retained by green roofs is detained, effectively increasing the time to peak, and slowing peak flows for a watershed.”

“There are seasonal considerations as more runoff is generated during winter and for many summer storms, there was no runoff. Green roof runoff does contain concentrations of some nutrients and other parameters, but values are in line with other planted systems. Due to the volume reduction, actual nutrient loadings from green roofs are less than asphalt roofing runoff or otherwise manageable at the downspout.”
