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

Axter's Service
The way we work and the way we think is what sets our service apart. We are a small and driven team, working with the latest technologies to minimise risk and maximise potential.
We provide a full service from concept design to completion and handover.
Concept Design
A Technical Sales Manager will be assigned to your project, becoming the single point of contact for your full project cycle. They will work collaboratively with all parties involved to ensure all construction implications (including budget and compliance) and appropriate sequence of works have been considered.
Our technical service includes: honest, expert advice; NBS specifications; BIM objects; and detail drawings.
Survey Technology
We use the latest in 3D scanning technology to create a detailed roof survey report to ascertain the condition and expected lifespan of the roof. This technology provides a rapid, precise measurement of roof geometry and drainage falls, and captures this data in just one visit.
The survey can typically include one or more of the following: core sampling, moisture map analysis, level survey analysis. thermographic imaging and drone survey.
Technical Design
Our in-house Design Team provides a project-specific bespoke design service, as well as a full suite of standard details.
Our design service includes, but is not limited to: design and technical calculations; U-Value calculations, tapered insulation design; wind loading calculations; rainwater drainage calculations.
Building Performance
We determine the existing performance of your roof and provide a full assessment for upgrade.
This typically includes: U-Value, drainage and wind uplift calculations; and a tapered design to improve drainage falls.

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.

East Dulwich, London
East Dulwich Road, a former manufacturing building, had been left vacant for years within a bustling neighbourhood in South London. The client had plans to convert this derelict building into a modern space for offices, but the current felt roof was in a poor state, suffering from water ingress and lacking insulation.
Cadbury College
A transformative refurbishment project - including a full strip and replacement of the existing 1,943m² roof area - Cadbury Sixth Form College in Birmingham showcases Axter’s commitment to high-performance, sustainable waterproofing solutions within the education sector.
Abbots Avenue West
The refurbishment of these flats in St. Albans presented a unique set of challenges. Due to the severity of its existing roofing issues and with residents in situ, all parties involved needed to utilise their expertise and new technology to ensure work was completed swiftly, and to the highest standard.
