Flat Roof Systems with Green Roofs
Incorporating green roofs into a flat roof system brings environmental and aesthetic benefits:
Environmental Impact: Green roofs improve air quality, reduce the urban heat island effect, and promote biodiversity. By supporting plant life, they help to filter pollutants from the air while creating a natural habitat for birds and insects.
Energy Efficiency: They provide natural insulation, reducing heating and cooling costs throughout the year. Green roofs installed in a flat roof system also help to stabilise indoor temperatures, reducing the reliance on artificial heating and cooling systems and leading to significant energy savings.
Stormwater Management: The vegetation layer absorbs rainwater, reducing runoff and easing pressure on drainage systems. This helps to mitigate flood risks and prevents excessive strain on urban drainage infrastructure, especially in areas prone to heavy rainfall.
Extended Roof Lifespan: A green flat roof system protects the underlying waterproofing membrane from UV exposure and temperature fluctuations, extending its durability and reducing maintenance costs over time.

How to Construct a Flat Roof System
High quality flat roof waterproofing is essential to permanently protect your building from water and moisture ingress. There are three kinds of flat roof construction that our products are optimally suited for; warm roof, cold roof and inverted roof.
If you have any specific questions, please feel free to contact our team of experts today.
Warm roof construction
A ‘Warm Roof’ is where the insulation is on top of the roof deck, i.e. the flat roof system becomes warm. They are more complex than cold roof constructions but offer a number of advantages.
They are more energy efficient, they provide better insulation against noise and they are less likely to suffer from condensation problems.
This is a reliable and preferred method of construction and provides robust detail. It is easier to calculate and achieve the required thermal performance (known as U-Value) by installing the appropriate insulation thickness.
Most modern flat roof systems are built as unventilated warm roofs, with waterproofing applied directly over the insulation. A key component of this system is a vapour control layer (VCL) which prevents moisture ingress.
%3Aquality(75)%3Fupdated_at%3D2023-08-15T15%3A00%3A19.382Z&w=3840&q=75)
Cold roof construction
Cold roofs have insulation placed below the roof deck between the joists, unlike uninsulated roofs, which lack insulation altogether.
Typically made from mineral wool such as Rockwool, this insulation helps maintain thermal efficiency. The waterproofing layer is applied directly to the structural deck, and proper ventilation of the void is necessary to prevent moisture buildup.
Cold roofs are ideal where the overall building height must be minimised, such as near adjoining structures with low window or door sills or to comply with planning restrictions.

Inverted roof construction
When it comes to flat roofing systems, inverted roofs are a smart choice for durability and strength.
Unlike traditional warm roofs, inverted roofs feature a waterproofing layer applied directly to the roof deck, with insulation situated below.
This construction style makes inverted roofs ideal for areas with high foot traffic, such as podium decks, terraces, and walkways.
Inverted roofs are an excellent option for a flat roof system that may face heavy snow loads in the winter.

Flat Roof System Repairs
Flat roofs with EPDM systems require low maintenance and are extremely durable in comparison to other flat roof systems such as felt.
However, any roof is susceptible to damage from nearby tree debris in high winds or even falling debris from nearby buildings. If you’re unfortunate enough to have damage to your flat roof membrane, they are easy to repair using specific EPDM flat roof repair kits.
Whether you’re looking for a full roof replacement or just need to patch specific areas with fillers, coatings or other flat roof repairs, our team of specialists can assist you with the best systems and kits for your project.

Creating Falls on a Flat Roof
Building Regulations Part H mandates that adequate drainage systems are in place to effectively remove rainwater from roofs.
As outlined in BS 6229 and BS 8217, flat roofs should be designed with a minimum fall of 1:40 to ensure a finished fall of 1:80.
This slope is essential for proper water runoff, accounting for potential construction variations. These requirements apply to both general roof areas and internal gutters.
