What is Green Roofing?
Green roofing adds a layer of vegetation to a suitable flat roof. Beneath the plants and growing medium, drainage layers manage excess rainwater while a waterproofing system protects the building below.
Green roofs can support a building’s energy efficiency by providing an additional layer of insulation and helping regulate roof temperatures. Each layer works together to support healthy vegetation, manage water and maintain reliable roof performance. The exact build-up will depend on the building, roof structure and type of planting required.

Is Green Roofing Right for Your Building?
Unfortunately, green roofing is not suitable for every building. Structural capacity and roof loading must be assessed to determine whether the roof can safely support the complete system, including water-saturated growing materials and vegetation.
Building use, maintenance requirements and sustainability targets should also inform the specification. As green roofing can require a significant upfront investment, it may not be suitable for every project budget.
Planning requirements can vary by project and location, so these should be checked with the relevant local authority or appointed planning professional before work begins.

Green Roofing FAQs
What is green roofing?
Green roofing is a layered roof system containing vegetation and growing medium above drainage and waterproofing components. It is also known as a living or vegetated roof.
What are the benefits of a green roof?
A green roof can support biodiversity, manage rainwater, improve thermal performance and enhance a building’s appearance while contributing towards wider sustainability objectives.
How much maintenance does a green roof require?
Maintenance depends on the planting and system design. Routine visits typically involve checking vegetation, drainage outlets, waterproofing details and removing unwanted growth or debris.
Can an existing roof be converted into a green roof?
Potentially, but its structure, waterproofing and drainage must first be assessed. The roof must safely support the additional load, particularly when the system is saturated.
Which buildings are suitable for green roofs?
Commercial, residential and industrial buildings may be suitable, provided the structure, roof design, drainage and access arrangements can safely accommodate the proposed green roof system.
How long does a green roof last?
Its lifespan depends on the specification, installation, waterproofing and maintenance. AAC can explain the expected design life after assessing the building and proposed system.
Do you install green roofs across the North West?
Yes. AAC installs green roof systems across the North West for suitable commercial, residential and industrial developments, supported by experienced project management.
