Flat Roof Insulation
If your flat roof was built before 2000, chances are it doesn’t meet today’s insulation standards.
This could mean your home is losing heat unnecessarily resulting in higher energy bills and a less comfortable living space. Re-insulating your flat roof could make a big difference.
Current building regulations in England and Wales recommend at least 150mm of insulation, but many older properties have significantly less—often around 100mm or below.
Flat roofs are generally built using either a cold deck or warm deck design. Cold decks, commonly found in older homes, are less energy efficient because of how the insulation sits in relation to the joists and rafters.
At Nexus Eco Built, we assess your roof’s structure and recommend the best insulation upgrade to improve thermal performance and comfort.
Keep in Mind: Flat Roof Insulation Needs a Tailored Approach
Insulating a flat roof isn’t quite the same as insulating a traditional loft. Every flat roof comes with its own set of challenges—from height restrictions and low balcony thresholds to internal features like roof lights and kerb vents—all of which can impact the space available for proper insulation.
At Nexus Eco Built, we understand these complexities. Our skilled team has extensive experience resolving flat roof insulation issues and will work closely with you to find the right solution for your property. We aim to help you retain as much warmth as possible while ensuring full compliance with UK Government standards.
