Flat Roof Refurbishment & Retrofit
Upgrade, protect and rethink; breathe new life into your flat roof.
Refurbishment and Retrofit
A modern flat roof isn’t just waterproof; it can provide insulation, manage stormwater, support biodiversity and even generate energy. Axter's refurbishment offering is about going beyond what’s necessary. We want to maximise the full potential of the roof.
Refurb projects will become a huge part of our sustainability pathway, as we shift the focus towards maintaining and protecting what already exists in this world.
Upgrade, protect and rethink.
Let's breathe new life into the buildings that already exist. We'll help you to discover new ways to better utilise the roof space...
- Improve drainage
- Upgrade thermal performance
- Enhance energy efficiency
- Lean energy generation with Solar PV
- Create a space for biodiversity within cities
- Supports achieving Net Zero for housing stock

Sustainability
Refurbishment and Sustainability
Roof refurbishment presents a critical opportunity to improve the environmental performance of existing buildings.
Refurbishing a roof enables significant thermal upgrades that can dramatically improve energy efficiency. With approximately 25% of a building’s heat loss occurring through the roof, refurbishment is one of the most effective strategies for reducing energy consumption and carbon emissions.
Our systems are designed to support the addition of sustainable technologies and systems to existing roofs, including:
- Blue roofs for controlled stormwater management and climate resilience
- Green roofs that enhance biodiversity, reduce urban heat island effects and extend waterproofing lifespan
- Solar PV systems that generate clean, renewable energy and lower operational carbon
Whether you are targeting EPC improvements, regulatory compliance, or broader ESG goals, Axter’s refurbishment systems offer a practical, low-disruption route to reducing emissions and futureproofing your assets.
