Green Roofing in Colchester, Essex, Roof Gardens

Green Roofing / Roof Gardens

With ever increasing environmental concerns dictating our landscape, Green Roofs offer an eco friendly solution with numerous environmental benefits, such as increasing biodiversity, reducing air pollution, storm water management, environmental aesthetics, photosynthetics and reducing urban heat island effect, proving favourable for planning proposals.

They also bring many financial benefits by increasing insulation, thereby reducing your heating and cooling expenses, increasing your roofs life expectancy and increasing your property value.

GRM installed our first Green Roof system in 1993 and have since embraced the Green Roof concept, becoming one of the UK’s most experienced Green Roof contractors.

When designing a Green Roof, issues such as waterproofing, thermal calculations, root protection and intensive/extensive landscaping options need to be considered for maximum durability of any installation. GRM can offer this advice to our clients, resulting in systems that are able to offer a guarantee of up to 20 years, whilst doubling the life expectancy of a conventional flat roof.
