Infrared Roof Moisture Surveys

  • Pinpoint and Document Areas of Wet Insulation in Flat Roofs
  • Reduce your risk with critical information
  • Document your work to avoid costly disputes
  • Help build customer respect and loyalty
  • Demonstrate your commitment to energy savings

More and more roofing contractors are using our Infrared, Nuclear and Capacitance Roof Moisture Testing services to boost their bottom line, reduce liability, improve bidding, and land more jobs.

How It Works:

During the day, wet roof insulation absorbs much more solar heat than dry insulation. At night, these wet roof materials release this "solar gain” as radiant heat, which is detectable with the infrared camera. Our Certified Thermographers use state-of-the-art cameras to capture the "thermal signature” of the roof’s nighttime heat loss.

Infrared thermography is a proven scientific method for evaluating roof condition. Our professional infrared surveys give you the in-depth information you need to fully understand the roof condition, optimize your estimates, and provide bid-winning solutions for your customers.

About Our Reports:

Our professional testing reports lead the industry in quality, accuracy and detail. Our infrared roof inspection reporting services include:

Complete Roof Markout: Included with all inspections. Our technicians mark the boundaries of moisture-damaged areas on the roof surface to guide subsequent repairs or replacement.

Infrared Roof Moisture Survey Report: A full-color bound report that includes an in-depth written analysis of all findings from our visual and thermographic inspection.

AutoCAD® Roof Map: We document our thermographic data with AutoCAD scaled drawings of the complete roof system, in both large (36" x 24") and small sizes.

Nuclear Roof Moisture Surveys

  • Only accurate method for testing ballasted roofs
  • Provides excellent information at low cost
  • Locates moisture damage for targeted repair or replacement

Ballasted roof systems present special challenges and should be tested with nuclear moisture detection technology. A nuclear moisture gauge uses tiny amounts of radiation to detect hydrogen ions, which indicate the presence of water after other sources of hydrogen are factored out. A nuclear roof moisture survey is typically conducted on a 10’ x 10’ grid pattern across the roof surface. Readings are taken at each intersection to build a hydrogen inventory of the roof system, enabling us to accurately map moisture damage deep within the roof system.

Nuclear Testing can be performed during the day and in various kinds of weather. Nuclear moisture analysis remains the only accurate method for testing the extent and location of moisture damage in ballasted roofs. Its unique ability to deeply penetrate roof materials makes it an invaluable tool for evaluating internal roof condition.

Capacitance Roof Moisture Surveys

  • Highly Sensitive Moisture Detection
  • Identifies sound, dry sections suitable for conservation
  • Employs state-of-the-art nondestructive impedance moisture meter
  • Tests both capacitance and resistance for most accurate results
  • Complies with ASTM D7954
  • Suitable for non-conductive membranes
  • Efficient and cost-effective

Our technicians use electrical impedance (capacitance) moisture meters to detect the presence of moisture within roofing and waterproofing systems. IR Analyzers' state-of-the-art impedance surveys test both capacitance and resistance for the most accurate results in a wide range of materials and constructions. This technology can rapidly detect small amounts of moisture to provide an accurate picture of the internal condition of the roofing or waterproofing assembly.

ELD Fusion®

Take the Next Step in Electronic Leak Detection - Get Complete Coverage with new ELD Fusion®

 Now you can get virtually 100% testing on your work with ELD Fusion®, our unique combination of High and Low Voltage Electronic Leak Detection methodologies. ELD Fusion combines traditional Low Voltage Vector Mapping (wet testing) on large horizontal areas with High Voltage ELD (dry testing) on vertical surfaces, transitions, and other areas not tested with the low voltage technique. ELD Fusion gives you 100% coverage – and 100% peace of mind that your membrane will be leak free.

Traditional Low Voltage Vector Mapping is an accurate and reliable technique for integrity testing on large, wide open areas. But standard low voltage methodology does not typically test many of the areas that require the most careful and conscientious work – parapets and curbs, flashings, and transitions from horizontal to vertical surfaces. With our two-prong approach – testing all of these areas with High Voltage Leak Detection and then overlapping them with Low Voltage Vector Mapping - you get complete coverage.

The Most Complete Testing Available Now, for the same or even reduced cost, you can get the many benefits of ELD Fusion and rest assured that the entire membrane has been thoroughly tested and any problems have been pinpointed and isolated for repair. It’s time to take the next step in Electronic Leak Detection. Get a truly comprehensive evaluation of your membrane with ELD Fusion, performed by our experienced ELD Technicians. With ELD Fusion, we’ve got you covered - completely!

Low Voltage Vector Mapping

  • Quality Assurance Testing of New Roofing and Waterproofing Membranes
  • Verifies Green Roof Membranes Prior to Installing Overburden
  • Pinpoints Leaks in Roofing & Waterproofing Membranes
  • Ideal for Warranty Verification
  • Locates Breaches Too Small to Detect Visually

Electronic Leak Detection: Less Expensive, Safer, Faster, and More Accurate Than Flood Testing

In low voltage vector mapping, the surface of the roof membrane is moistened (not flooded) to create an electrically conductive medium. A conductive wire loop is laid on the membrane around a section of the area to be tested. One lead from a pulse generator is connected to this wire loop perimeter. The other lead from the generator is connected to the structural roof deck.

Leaks or breaches in the membrane are detected when the electric current flows across the membrane and down through the breach to the deck, completing the circuit. The technician uses two probes connected to a receiver to determine the direction of the electric current and precisely locate the breach.



High Voltage Electronic Leak Detection

  • Quality Assurance Testing of New Roofing & Waterproofing Membranes
  • Verifies Green Roof Membranes Prior to Installing Overburden
  • Pinpoints Leaks in Roofing & Waterproofing Membranes
  • Ideal for Warranty Verification
  • Locates Breaches Too Small to Detect Visually

High voltage testing is performed on a dry horizontal or vertical surface using a very small current at relatively high voltage for safe and reliable testing. One lead from the portable current generator (charger) is grounded to the roof deck (either metal or concrete) or foundation walls. The other lead is attached to a special electrode brush made with highly conductive metal bristles. As the technician "sweeps” the brush electrode over the surface of the roof membrane, electricity will flow through any breach in the membrane, completing a circuit between the brush and the roof deck. Where there are no breaches, the membrane acts as an insulator and prevents the flow of current to the deck.

High Voltage ELD vs Low Voltage Vector Mapping:

Both High Voltage ELD and Low Voltage Vector Mapping can be employed on most roofing and waterproofing membranes. However, because the High Voltage brush sensor must make direct contact with the membrane, roofs with overburden (vegetation, pavers, ballast, etc.) must be tested with Low Voltage Vector Mapping. Neither method can reliably inspect black EPDM membranes, which contain carbon black and are therefore electrically conductive.

High Voltage testing is often faster, simpler and less expensive than Low Voltage Vector Mapping, which requires more setup as well as constant wetting of the membrane. The interpretive nature of Low Voltage testing can require more inspection time, particularly if multiple breaches are present. Both techniques are safe, cost-effective and highly reliable, allowing problem areas to be quickly marked, repaired, and re-tested.
