Our equipment and how it works
DRY ROOF 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 ROOF 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

At All Weather Roofing, we specialise in flat roof leak detection services in Newport Pagnell, Milton Keynes, and the surrounding areas. We understand that a leaking flat roof can cause significant damage and inconvenience, which is why we offer comprehensive leak detection solutions using advanced techniques such as electronic leak detection. Whether you have a leaking single-ply flat roof, leaking felt roof, leaking GRP roof, leaking EPDM roof, or leaking liquid roof, our experienced team is here to help.
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.
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.

Electronic Flat Roof Leak Detection
Electronic flat roof leak detection is one of the most effective ways to locate hidden defects in suitable flat roof membranes. Using specialist testing equipment, we can help identify punctures, failed seams, pinholes, splits and breaches that may not be visible during a standard roof inspection.
This method is especially useful on single ply membranes, Sikaplan roofing systems, EPDM roofs, PVC membranes and commercial flat roofs where a small defect can allow water to travel beneath the surface before appearing inside the building. Electronic leak detection can also be used for new roof integrity testing, helping confirm that a newly installed flat roof is watertight before handover.
At All Weather Roofing Ltd, we combine electronic leak detection with our flat roofing knowledge, so we do not just find the problem — we can also advise on the correct repair, overlay or replacement solution.
Moisture Mapping & Roof Condition Reports
Moisture mapping is used to identify areas of trapped moisture within a flat roof build-up. This is especially useful on larger commercial roofs, warm roofs, overlaid roofs and roofs where the source of water ingress is not immediately obvious.
Water can travel underneath a flat roof covering before showing inside the building, meaning the internal leak may not be directly below the actual defect. Moisture mapping helps us understand where moisture is present, how far it may have spread and whether the roof can be repaired locally or if a larger area needs attention.
Following inspection, we can provide clear findings, photographs and recommendations. This can be very useful for landlords, property managers, commercial clients, insurance purposes and planned roof maintenance.
Commercial Roof Leak Detection
Commercial roof leaks can cause serious disruption to businesses, tenants, staff and customers. Water ingress can damage ceilings, stock, insulation, electrical systems, internal finishes and building fabric if not dealt with quickly and correctly.
All Weather Roofing Ltd provides commercial roof leak detection for offices, schools, industrial units, retail premises, apartment blocks, warehouses and managed properties across Milton Keynes, Newport Pagnell and surrounding areas.
We can inspect large flat roof areas, investigate repeated leaks, carry out moisture mapping, check outlets, rooflights, plant penetrations, parapet walls and roof details, and provide a clear repair plan. Where possible, we can also carry out repairs after locating the defect, reducing the need for multiple contractors.
Domestic Flat Roof Leak Detection
Domestic flat roof leaks can be frustrating because the source is not always obvious. A leak may appear in a ceiling, wall, window reveal or cavity, but the actual defect could be several metres away on the roof.
We investigate leaks on home extensions, garages, dormers, balconies, porches, garden rooms and outbuildings. Common causes include cracked GRP, split felt, failed EPDM joints, damaged single ply membranes, poor rooflight details, blocked outlets, failed trims, parapet wall issues and poor previous repairs.
Our aim is to find the cause of the leak and recommend the correct long-term solution, whether that is a targeted repair, improved detailing, a roof overlay or a full flat roof replacement.
Flat Roof Systems We Test
We can investigate water ingress on a wide range of domestic and commercial flat roofing systems. Every roof type behaves differently, which is why it is important to use a leak detection company that understands flat roofing as well as testing.
We can inspect and test Sikaplan single ply membranes, PVC single ply roofs, EPDM rubber roofs, GRP/fibreglass roofs, felt flat roofs, liquid-applied systems, warm roofs, cold roofs, inverted roofs and commercial roof overlays.
Because we are flat roofing specialists, we understand the common failure points in each system. This helps us identify whether the issue is caused by a puncture, failed seam, poor detailing, trapped moisture, damaged insulation, faulty outlet, rooflight detail, parapet wall or ageing roof covering.
Our Leak Detection Methods
Every flat roof leak is different, so we use the most suitable testing method depending on the roof type, access, weather conditions and symptoms of the leak. In some cases, a visual inspection may identify the issue quickly. In more complex cases, further testing may be required.
Our leak detection methods can include visual roof inspections, electronic leak detection, Tramex moisture mapping, flood testing and dye testing. These methods help us build a clearer picture of how water is entering the property and whether it is coming through the roof covering, roof details, outlets, walls, parapets, windows or another source.
By combining testing methods with practical flat roofing experience, we can provide a more accurate diagnosis and a clear recommendation for repair.
Visual Roof Inspections
A detailed visual roof inspection is often the first step in locating a flat roof leak. We check the roof covering, joints, seams, laps, trims, outlets, rooflights, upstands, parapet walls, flashings and any penetrations through the roof.
Many leaks are caused by small defects such as failed sealant, damaged trims, cracked GRP, split felt, open seams, blocked outlets or poor detailing around rooflights and walls. These problems can often be missed without a careful inspection by someone who understands flat roof systems.
If the cause of the leak is visible, we can advise on the correct repair. If the issue is hidden beneath the surface, we may recommend further testing.
Tramex Moisture Mapping
Tramex moisture mapping helps identify areas where water may be trapped within the roof build-up. This is particularly useful on commercial roofs, warm roofs, inverted roofs and roofs that have been overlaid.
Moisture mapping can show whether water is isolated to one area or has spread across a larger section of the roof. This helps avoid unnecessary stripping and allows repair works to be targeted more accurately.
It is also useful when deciding whether a roof can be repaired, overlaid or whether sections need to be removed because of saturated insulation or trapped moisture.
Flood Testing
Flood testing involves applying water to a controlled area of the roof to help confirm whether a specific section is allowing water ingress. This method can be useful when a leak only appears during heavy rain or when the suspected area needs to be tested under controlled conditions.
Flood testing must be carried out carefully, with suitable drainage, safe roof access and consideration of the roof structure. It may also require a water supply and enough time to monitor whether water appears inside the building.
This method is particularly useful for complex roof details, balconies, outlets, flat roof sections and areas where water ingress is difficult to reproduce.
Dye Testing
Dye testing uses coloured dye to help trace the route water is taking through a roof, outlet, parapet, cavity or roof detail. This can be useful where water is travelling through hidden areas before appearing internally.
Dye testing is often used alongside flood testing or visual inspections, especially on complex roofs, inverted roofs, balconies, parapet walls and drainage outlets.
This method can help confirm whether water is entering through the roof covering, a wall detail, a drainage point or another area of the building.
