About Us

Specialist Roofing & Waterproofing. Over 30 Years of Experience.

Infallible Systems Ltd is an established roofing and waterproofing contractor with over 30 years of industry experience, delivering specialist solutions across the commercial, industrial and construction sectors.

Based in Erith, Kent (DA8), and originally established in South London, we have developed a strong reputation for technical expertise, quality workmanship and dependable service. Our approach is built around providing clients, architects, surveyors, consultants and main contractors with practical, technically appropriate and durable roofing solutions.

Originally established by Geoff Evans, and now under the ownership of John Chapman who has worked with the company for over 30 years, Infallible Systems combines extensive industry knowledge with a progressive approach to roofing technology and systems. John leads an experienced and long-serving team, ensuring that the knowledge and craftsmanship developed over decades continues to underpin every project we undertake.

Specialist Expertise, Proven Solutions

Our heritage is rooted in mastic asphalt, a specialist waterproofing material with a proven track record for durability, longevity and versatility.

We continue to maintain a high level of expertise in this specialist discipline, investing in skilled operatives and apprentices to ensure that traditional craftsmanship is not lost. At the same time, we have continually developed our capabilities to incorporate modern roofing and waterproofing technologies.

Our specialist mastic asphalt services include applications such as the Paco Patch system for setting ironwork, alongside a broad range of specialist waterproofing applications.

Today, our expertise extends across a comprehensive range of roofing, waterproofing, repair, refurbishment and renewal systems, enabling us to select and deliver solutions appropriate to the specific requirements of each project.

A Complete Roofing & Waterproofing Service

Over more than three decades, we have expanded our portfolio to provide clients with a broad range of proven roofing systems and specialist services.

Our experience enables us to work across projects ranging from planned maintenance and remedial works through to major roof refurbishment, renewal and specialist waterproofing schemes.

We understand that every building and project presents different challenges. Our role is to identify the underlying requirement, provide clear technical advice and recommend a solution that delivers the appropriate balance of performance, durability, value and longevity.

Where required, we are able to work closely with architects, surveyors, consultants, facilities managers and main contractors, providing specialist roofing knowledge from initial enquiry and specification through to completion.

Other waterproofing systems include mastic asphalt paving/LU & TFL platforms and overbridges, felt roofing, hot melt, cold melt, liquid waterproofing, slate and tile, lead, copper and zinc works.

Quality, Reliability & Professional Service

Our reputation has been built on the principles of quality workmanship, honest advice and reliable service.

We provide clear and considered quotations, communicate openly with our clients and take pride in delivering work to a consistently high standard. Our experienced workforce gives us the capability to undertake technically demanding projects while maintaining the attention to detail expected from a specialist contractor.

We believe that long-term relationships are built through performance. Consequently, we place considerable importance on professionalism, reliability and delivering work that meets the requirements of the project rather than simply providing a short-term solution.

Investing in People & the Future

Maintaining high standards requires investment in people as well as materials and systems.

Infallible Systems operates as a close-knit specialist business, allowing experienced personnel to work closely with the wider team and maintain a consistent approach to quality and workmanship.

We actively support in-house and external training, professional development and apprenticeships, ensuring that our workforce continues to develop alongside the roofing industry.

This combination of established expertise and developing skills allows us to retain the craftsmanship associated with our heritage while embracing new technologies and working practices.
