Practical Facade & Roof Leak Investigation Methods
Download Our Technical CPD Accredited Presentation
Originally developed as a Continuing Professional Development (CPD) seminar for building surveyors and property professionals, this presentation is now available as a free download.
Learn a systematic approach to identifying the true source of water ingress in commercial buildings.
Water ingress is one of the most common—and often most challenging—issues affecting commercial buildings. Leaks are frequently misdiagnosed because water can travel significant distances through the building fabric before becoming visible, resulting in unnecessary repairs, repeat failures and increased maintenance costs.
Although we no longer deliver this session as a live CPD, the technical content remains highly relevant for anyone responsible for inspecting, maintaining or managing commercial buildings.
Download the presentation to learn:
- Why roof and façade leaks are commonly misdiagnosed
- How water travels through the building envelope
- The difference between condensation and water ingress
- A systematic approach to investigating roof leaks
- When and why different diagnostic techniques are used
- How evidence-led investigations help avoid unnecessary repairs
- Lessons learned from real commercial building investigations

What You'll Learn
This presentation shares the same practical methodology used by Building Transformation’s building envelope specialists when investigating water ingress across commercial properties.
Understanding Building Envelope Failures
Explore why leaks are often more complex than they first appear and why visible water ingress rarely indicates the true source of the problem.
A Structured Investigation Methodology
Learn a logical process for investigating roof and façade defects before specifying remedial works, helping reduce assumptions and improve diagnostic accuracy.
Specialist Investigation Techniques
The presentation introduces several methods commonly used during leak investigations, including:
- Electronic Leak Detection (ELD)
- Progressive water testing
- Spray bar testing
- Moisture mapping
- Thermal imaging
- Visual condition surveys
- Roof outlet testing
Commercial Roofing Systems
Gain a better understanding of common commercial roof constructions and the types of defects that typically lead to water ingress.
Real Project Case Studies
See how systematic investigation techniques have been used to identify hidden defects, reduce unnecessary remedial works and provide clients with confidence that repairs address the true cause of failure.
Why Download This Presentation?
Many roof leak repairs fail because the underlying cause has never been properly identified.
This presentation explains how a structured investigation process can help you make more informed decisions, improve the accuracy of defect diagnosis and reduce unnecessary expenditure on ineffective repairs.
Rather than focusing on repair products, it demonstrates the importance of understanding how buildings fail and why evidence should always inform remedial recommendations.
Who Will Benefit?
This presentation has been created for professionals involved in the inspection, maintenance and management of commercial buildings, including:
- Building Surveyors
- Property Managers
- Facilities Managers
- Asset Managers
- Estates Managers
- Building Owners
- Project Managers
- Building Consultants
Whether you’re investigating a recurring leak, planning maintenance works or specifying repairs, the presentation provides practical insight into building envelope diagnostics and investigation techniques.
Frequently Asked Questions
Is this still an accredited CPD seminar?
No. We no longer deliver this presentation as a live CPD session. However, the technical content remains relevant and is available as a free educational download.
Who is the presentation intended for?
It has been developed for building surveyors, property managers, facilities managers, asset managers, consultants and other professionals responsible for maintaining commercial buildings.
What topics are covered?
The presentation explains common causes of roof and façade leaks, investigation methodologies, diagnostic testing techniques and real project examples, helping readers understand how to identify the true source of water ingress before repairs are specified.
Does the presentation explain Electronic Leak Detection?
Yes. It introduces Electronic Leak Detection (ELD) and other specialist investigation techniques, explaining when they may be appropriate as part of a wider diagnostic strategy.
Can Building Transformation carry out leak investigations?
Yes. We provide building envelope investigations, specialist testing and evidence-led reporting to help identify the root cause of water ingress and inform effective remedial solutions. To find out more about our leak investigation services, get in touch.
