Commercial flat roofing contractors
High-quality installations backed by industry expertise, safety compliance and proven workmanship - including full structural roof replacement above buildings that cannot afford to close.
A roofing division built on the same discipline as the fit-out business.
JPS launched its flat roofing division to offer a complete range of roofing and structural waterproofing solutions. Our team specialises in large-scale residential, commercial and industrial projects - from multi-unit housing developments to complex commercial buildings - delivering quality, longevity and sustainability.
Our expertise lies in technically robust systems: industry knowledge, precision workmanship and proven build-ups that hold up over decades rather than over a defects period.
Large housing developments
Durable, compliant roofing delivered at scale across multi-unit residential schemes.
Commercial and industrial
High-performance systems for commercial and industrial buildings, new and existing.
Public sector
Roofing for public sector estates, combining durability, compliance and programme certainty.
New build and refurbishment
Whole-envelope roofing on new build, and structural replacement or overlay on existing assets.
Our roofing solutions.
Five system families, chosen against the building rather than against a preferred supplier list. Each one is the right answer to a different problem.
Built-up felt systems
Durable multi-layer systems for flat roofs, offering a high-performance, weather-resistant solution at any scale.
Single-ply membranes
Flexible, lightweight and long-lasting, with strong resistance to weather, UV and other external forces.
Green and bio-diverse roofing
Roof systems that support biodiversity and improve energy efficiency, turning dead roof area into habitat.
Liquid waterproofing
A seamless, cold-applied waterproof layer for intricate roof shapes, penetrations and complex detailing.
Structural waterproofing
Protection for commercial and residential structures against water ingress and moisture damage below ground.
Industries we serve.
From commercial and industrial developments to public sector and residential schemes, tailored to the specific demands of each environment.
Commercial
Offices, retail parks and mixed-use buildings, frequently occupied and trading throughout.
Industrial
Warehousing, distribution and manufacturing, where the roof area is large and downtime is costly.
Retail
Shopping centres and high street units, where public safety and continuous trading govern the method.
Education
Schools and campuses, typically programmed into holiday periods with fixed, immovable end dates.
Accessories and finishes, specified with the system.
Supplied and installed as part of the roof rather than added afterwards, so the guarantee position stays intact.
Photovoltaic systems
Integrated PV designed for flat roofs, improving energy efficiency and generating on site. Mounting and waterproofing are resolved together so the array never compromises the roof it sits on.
Roofing finishes
Reflective coatings, colour options and textured surfaces that change how a roof performs as well as how it looks - solar reflectance reduces surface temperature and thermal movement.
Roof accessories
Edge trims, skylights, ventilation and drainage, supplied and installed as part of the system rather than added afterwards, so the guarantee position stays intact.
Have a roof that needs replacing?
We have done it above a trading shopping centre, with the tenants below open the whole time. Tell us what is on top of the building and what is underneath it.
