Leak Detection
We offer a full Leak detection service with the latest roofing technology.
Our leak detection service is carried out by our inhouse fully trained professionals. Every leak detection service comes with a full comprehensive condition report, giving a in-depth view of your roof and works required.
Our equipment and how it works
DRY LEAK DETECTION
The dry roof leak detector applies a high-voltage DC current to the surface via an electrode (such as a phosphor-bronze brush) connected to the detector unit. An earth return lead from the detector unit is connected to a known earth on the building’s structure. As the operator passes the electrode brush over the roof’s non-conductive surface, any holes allow the completion of an electrical circuit triggering the detector unit’s alarm highlighting a fault's location.
WET LEAK DETECTION
The Wet Roof Pro’ uses the 'vector-mapping' or 'earth leakage' method of locating faults. The conductive properties of water (from either rainfall or a hose) provide a medium through which electrical current can flow, allowing the user to pinpoint leaks. The kit comprises two main elements; a generator unit and a detector unit. The generator unit creates an electrical field across the roof surface via a ‘boundary wire’ which is positioned around the perimeter of the test area and connected to the negative terminal on the generator unit. The positive terminal is connected to a suitable earth on the building’s structure.
Tramex Dec scanner – Professional Roof Moisture Detection
Precision Flat Roof Moisture Surveys with the Tramex Dec Scanner
At All Weather Roofing Ltd, we use the latest technology to provide detailed, non-destructive roof moisture inspections. One of our go-to tools for large-scale flat roofing assessments is the Tramex Dec Scanner—a top-tier scanning device designed specifically for detecting moisture in roofing systems.
Whether you're dealing with an aging flat roof or suspect water ingress beneath your membrane, the Tramex Dec Scanner helps us pinpoint moisture issues quickly and accurately.
What Is the Tramex Dec Scanner?
The Tramex Dec Scanner is a portable, electronic moisture detection instrument used for surveying flat roofing systems. It allows us to scan large roof areas rapidly, identifying hidden moisture trapped beneath the surface—without the need for core sampling or invasive procedures.
This robust tool is specifically engineered for roofing professionals, delivering real-time readings over built-up, single-ply, and other low-slope roof membranes.
How the Tramex Dec Scanner Works
Non-Destructive Scanning
The Dec Scanner uses advanced impedance technology to detect changes in the electrical conductivity of roofing materials caused by moisture. It works without penetrating the surface, preserving the integrity of your roof.Three Sensitivity Ranges
With three selectable depth settings, the Tramex Dec Scanner can detect moisture at various levels within the roofing assembly—ideal for multiple roofing types and insulation thicknesses.Efficient Surveying
The unit is mounted on wheels and pushed across the roof surface. As it moves, it provides continuous, instant readings displayed on the integrated analog dial, allowing us to map out wet and dry zones.Visual Moisture Mapping
We mark areas of concern directly on the roof surface and document the findings through photos, notes, and optional integration with digital mapping software (like the Tramex Moisture Mapper).
Key Benefits of the Tramex Dec Scanner
✅ Fast & Reliable
Covers large flat roof areas in a fraction of the time compared to handheld meters or invasive testing.
✅ Non-Destructive Testing
No cutting, drilling, or damage to your roof membrane—just accurate data you can trust.
✅ Accurate Leak Detection
Identifies wet insulation and hidden leaks before they turn into major problems.
✅ Ideal for Pre- & Post-Project Surveys
Use it to assess roof conditions before maintenance and verify work after repairs or installation.
Ideal for Flat & Low-Slope Roofs
The Tramex Dec Scanner is ideal for inspecting:
Built-up roofing (BUR) systems
Modified bitumen
Single-ply membranes (EPDM, TPO, PVC)
Ballasted or gravel-surfaced roofs
This makes it the perfect tool for commercial buildings, warehouses, schools, hospitals, and other large-scale flat roofing systems.
Why Choose Us for Roof Moisture Surveys?
At All Weather Roofing Ltd, we combine expert knowledge with top-tier technology. Our team is trained in the latest diagnostic tools like the Tramex Dec Scanner to deliver accurate, clear, and honest reporting—so you can make informed decisions about your roofing system.
Whether you need a routine inspection, are buying or selling a property, or have an active leak issue, we’re here to help with fast response and trusted expertise.
Leaks in the roof membrane allow water to penetrate to the building’s structure; creating a short circuit. The detector unit is connected to two hand-held test probes which are held in contact with the roof surface.
By measuring the voltage differential between the test probes, the detector unit is able to direct the operator to the location of the leak.

Flat Roof Leak Detection
Identifying the source of a flat roof leak can be challenging, especially when it's not visible to the naked eye. Our flat roof leak detection service utilizes state-of-the-art equipment and methods to pinpoint leaks accurately. We employ both wet testing and dry testing techniques to simulate rainfall and assess the integrity of your flat roof system. Our experienced technicians meticulously inspect your roof, detecting even the smallest leaks and areas of vulnerability.
Electronic Leak Detection
To ensure the most precise and efficient leak detection results, we utilize electronic leak detection methods. This advanced technology allows us to detect leaks by using electrical currents and sensors, providing real-time data about the presence and location of leaks. Electronic leak detection is non-destructive, meaning it minimizes the need for unnecessary repairs and reduces costs associated with exploratory work.
Leak Detection Report
Once we have completed our flat roof leak detection process, we provide you with a detailed leak detection report. This comprehensive report outlines the findings of our inspection, including the identified leaks, areas of concern, and recommended repair solutions. Our goal is to empower you with the information you need to make informed decisions regarding your flat roof repairs, ensuring that the necessary measures are taken to prevent further damage and protect your property.
