RJ Evans Commercial Roofing Contractors

"Award Winning Nationwide Commercial Roofers"

RJ Evans Flat Roofing Ltd is a UK-wide commercial roofing contractor delivering engineered roofing systems for commercial and industrial buildings nationwide. RJ Evans design, install, inspect, maintain, and repair commercial roofing systems for office buildings, public-sector facilities, industrial units, logistics centres, retail developments, and mixed-use commercial properties across the United Kingdom. Commercial roofing in the UK presents demanding performance conditions driven by flat and low-slope roof designs, ageing commercial building stock, frequent rainfall, prolonged moisture exposure, and increasingly strict regulatory requirements around fire performance and energy efficiency. RJ Evans engineer commercial roofing systems specifically to meet these conditions, with every roof designed to manage structural loading, thermal movement, drainage performance, and long-term waterproof integrity at national scale. UK commercial buildings are typically required to accommodate rooftop plant, drainage infrastructure, access walkways, balconies, service penetrations, and maintenance traffic. These requirements place exceptional demands on roofing systems, particularly on large-format and complex buildings. RJ Evans design and install commercial roofing assemblies capable of withstanding persistent wet weather, freeze–thaw cycles, moderate UV exposure, and wind uplift across exposed urban, coastal, and industrial environments throughout the UK.

As a commercial roofing contractor operating nationwide, RJ Evans provide a full spectrum of professional services, including new commercial roof installations, targeted commercial roof repairs, planned preventative maintenance programmes, and detailed roof inspections. Every service is delivered with a focus on regulatory compliance, fire performance standards, rooftop safety requirements, and minimal disruption to ongoing building operations. RJ Evans work closely with property owners, managing agents, and facilities teams to ensure commercial roofs remain compliant, operational, and protected against premature failure. RJ Evans install and maintain high-performance commercial roofing systems suited to a wide range of UK building types and exposure conditions. These include single-ply membrane systems such as EPDM for large low-slope roofs, reinforced bituminous roofing for refurbishment and high-traffic areas, mastic asphalt roofing for podiums, balconies, and terraces, liquid-applied waterproofing systems for complex detailing and interfaces, and metal roofing systems where durability and structural constraints require them. System selection is driven by roof design, access limitations, structural capacity, exposure conditions, and long-term maintenance strategy. Effective commercial roofing is not the application of a single material, but the engineering of a complete, compliant roofing system. Through disciplined design, robust detailing, proven materials, and controlled installation standards, RJ Evans deliver commercial roofing systems that reduce lifecycle costs, improve weather resistance and thermal performance, and protect high-value commercial assets across the UK.

What Is Commercial Roofing for UK Buildings?

Commercial roofing for UK buildings is the design, installation, maintenance, and repair of roofing systems specifically engineered for commercial and industrial properties operating in the UK’s climate and regulatory environment. Unlike residential roofing, commercial roofing systems are typically flat or low-slope and must support rooftop plant, drainage infrastructure, access walkways, balconies, service penetrations, and ongoing maintenance activity while maintaining long-term watertight performance. In the UK, commercial roofing is shaped by frequent rainfall, prolonged moisture exposure, temperature fluctuations, wind uplift, and strict building regulations relating to fire performance, thermal efficiency, and safety compliance. Roofing systems must be engineered to manage structural loading, thermal movement, drainage efficiency, and complex detailing at parapets, penetrations, balconies, and podium interfaces without compromising waterproof integrity. Common commercial roofing systems used across the UK include single-ply membranes, reinforced bituminous roofing, mastic asphalt, liquid-applied waterproofing systems, and metal roofing solutions for specific structural or exposure requirements. System selection is determined by roof design, building use, access constraints, exposure conditions, and long-term maintenance planning rather than material preference alone. Effective commercial roofing is not simply the installation of a membrane, but the engineering of a complete, compliant roofing system. Long-term performance depends on correct system specification, professional installation, and regular inspection and maintenance to prevent water ingress, insulation failure, and premature system degradation. When properly designed and maintained, commercial roofing systems protect building fabric, preserve asset value, and support the uninterrupted operation of commercial properties across the UK.

How Does RJ Evans Deliver Commercial Roofing at National Scale?

Delivering commercial roofing at national scale requires more than material selection or installation skill. It requires a repeatable engineering and delivery framework that allows roofing systems to perform consistently across different building types, exposure conditions, and regulatory environments throughout the UK. RJ Evans Flat Roofing Ltd applies a structured national delivery model that aligns system design, installation control, and lifecycle management to ensure long-term performance on commercial buildings nationwide.

RJ Evans applies this delivery model consistently across all commercial roofing projects:

RJ Evans evaluates roof structure, deck type, and load requirements to ensure roofing systems are engineered for the structural realities of each building.
RJ Evans specifies compliant roofing assemblies that meet UK building regulations, fire-performance standards, and commercial insurance requirements.
RJ Evans designs roofing systems to manage UK environmental exposure, including prolonged rainfall, wind uplift, freeze–thaw cycles, and thermal movement.
RJ Evans accounts for rooftop equipment, drainage complexity, and access constraints through engineered detailing, drainage planning, and reinforced protection zones.
RJ Evans integrates installation controls and lifecycle planning to maintain consistent performance across a national portfolio of commercial roofs.

These national-scale engineering and delivery decisions produce the following system-level performance outcomes:

Engineered structural load paths specified by RJ Evans → distribute dead and live loads across flat and low-slope decks → roof structures remain stable without deflection or compression damage.
Code-compliant, fire-rated roofing assemblies installed by RJ Evans → meet inspection, insurance, and regulatory requirements → compliance and liability risk is reduced.
Wind-resistant attachment and detailing strategies used by RJ Evans → resist uplift forces across exposed urban, coastal, and industrial sites → membranes and edge details remain secure.
Drainage geometries designed and maintained by RJ Evans → evacuate rainfall efficiently despite complex roof layouts → ponding pressure does not compromise seams or insulation.
Durable membranes and reinforced protection zones selected by RJ Evans → tolerate maintenance traffic and rooftop equipment vibration → mechanical wear does not develop into leak paths.

Each of these performance outcomes is achieved through coordinated decisions covering structural assessment, system specification, fastening strategy, fire performance, drainage design, detailing standards, and ongoing inspection and maintenance controls. By applying this integrated delivery framework consistently, RJ Evans delivers commercial roofing systems that perform reliably across office buildings, industrial facilities, logistics centres, retail developments, and public-sector properties throughout the UK, while preserving asset value and minimising operational disruption.

Client Testimonials

Warren did a great job. He was very careful, considerate and went to great lengths to make sure the job was done properly. I would not hesitate to use RJ Evans Flat Roofing Ltd again.

Customer in Ingatestone

Highly recommended, not only for the service as my flat roof looks lovely!! But if you are in need of advice and are looking for an honest and friendly service Ryan goes above and beyond.

Angie Roberts, Brentwood, Essex

Ryan and team arrived, late afternoon, as agreed, to review balcony, approx. 25 square metres, 3 sides fed by tiled roof and one long length hand-rail. Problem, 3 leaks in different places from 10yr old asphalt roof. We discussed the problem and Ryan suggested a choice of two plan of action. We found his quotation very acceptable. This work was completed as agreed, in only a few days, to our complete satisfaction. Eight months after completion, I can now report that after a very wet winter, the roof is in a sound state. An excellent job done.

Customer in Cambridge

RJ Evans Flat Roofing Ltd I found by accident on the Internet. It was a video about asphalting steps. I called Ryan who was very professional and had a great deal of experience and knowledge. The job was booked in straightaway and a team set about taking off old asphalt rebuilding and repairing the big Victorian staircase and then asphalting. The finish was quite amazing, these guys are very skillful at what they do and My husband and I were delighted. They were a professional team really hard working and highly recommend them.

Customer in London

Having had huge problems with my neighbour who objected to any work being done on our party wall, Ryun personally went to speak to her putting her at ease and left everything so tidy after the job had been done. I’m very grateful, especially as this was a last minute request Ryun undertook despite being very busy. The workmanship looks very neat, and at last I have a happy neighbour.

Customer in London

All the other builders I’d called said they were busy until January! Ryun returned my call, visited on a very wet day and gave me a quotation for the job even though he said he was busy and lucky for me, not too far away on another job. On a sunny Saturday Ryun returned with his colleague- they were on time and did the job in a matter of minutes! Even though I only needed one tile replacing, whilst on the roof Ryun checked the remaining tiles and gave advice regarding moss build-up. I will definitely recommend his services.

Customer in Barking

Morning, I would like to say how thrilled we are with the job on our steps. If you need any reference or quote from me I’d be delighted to provide one. I was so nervous of doing anything to our house that might detract from it aesthetically.
The quality and precision of the finish is fabulous. Your team know their stuff, were professional, efficient, skilful and I am simply delighted with how it looks. The communication at all stages was excellent and I know you’re working hard in Covid times to keep things working which is hugely appreciated.
Thank you all!

Jane, Essex
