We’ve recently completed a flat roof refurbishment in Hunstanton, Norfolk, on a building containing several flats.
The project involved upgrading the roof insulation to meet current Building Regulations requirements for thermal performance, followed by the installation of a new Danosa high-performance built-up bituminous roofing system.
The flat owners now benefit from a better-insulated roof, improved weather protection and a 25-year guarantee covering both materials and workmanship.
Improving the Roof Insulation
Replacing a flat roof is a good opportunity to look at what’s beneath the waterproof covering. Insulation standards have changed considerably over the years, and older roofs don’t always provide the level of thermal performance now expected when substantial refurbishment work is carried out.
In Hunstanton, we addressed that as part of the same project rather than treating insulation as a separate job.
The insulation was upgraded to meet current Building Regulations requirements, helping to limit heat loss through the roof and improve the thermal efficiency of the building.
For the flat owners, that’s an important part of the refurbishment. A new waterproof covering protects against the weather, but the insulation beneath it also plays a part in how efficiently the building retains heat, particularly during the colder months.

Installing a Danosa Built-Up Bituminous Roofing System
With the insulation work complete, we installed a high-performance Danosa built-up bituminous roofing system.
This type of roofing uses multiple layers of reinforced bituminous membrane to create a durable, waterproof covering. It's a system we've used on numerous projects across Norfolk, including our previous flat roof refurbishment at Grove Road shopping parade in Norwich.
One of the advantages of a built-up system is its ability to provide dependable long-term weather protection across larger roof areas.
Of course, the materials are only part of the equation. With flat roofing, particular attention needs to be paid to roof edges, junctions and other vulnerable areas where water could potentially find its way beneath the covering.
Getting these details right is especially important on a shared roof, where a problem could affect more than one property.

A 25-Year Guarantee and Building Regulations Certification
The completed refurbishment comes with a 25-year guarantee covering both the roofing materials and our workmanship.
The work is also being certified through the NFRC Competent Roofer Scheme.
Each flat owner will receive their own Building Regulations Certificate of Compliance, providing formal confirmation that the roofing work meets the applicable requirements.
Having that documentation is particularly useful on a building with multiple owners, especially if individual flats are sold in the future.
