Top 6 Challenges of ELD Testing in New Construction

Roofing projects vary significantly depending on the type of project undertaken. However, new construction introduces particularly unique challenges that surpass those encountered in re-roofing projects. Below are the top six (6) challenges of electronic leak detection test in new construction.

1. Interference- Detailing

Challenge: Construction materials such as metal counterflashing coming into contact with membrane, un-flashed rebar, form holes or other conductive substances, may interfere with the ELD testing process.

Impact: Slows testing production due to false readings or challenges in accurately pinpointing leak locations.

2. Integration with Construction Schedule

Challenge: ELD testing needs to be integrated into the construction schedule, which may have tight timelines.

Impact: The need to coordinate testing with construction activities can lead to scheduling conflicts and may require careful planning to avoid delays.

3. Limited Accessibility

Challenge: In new construction, certain areas of the roofing system may have limited accessibility.

Impact: Limited access can hinder the thorough application of ELD testing in all areas, potentially leaving some sections untested and vulnerable to undetected leaks.

4. Weather-Dependent Limitations

Challenge: ELD testing is can be weather-dependent, with certain conditions affecting the accuracy of results.

Impact: Adverse weather conditions, such as rain or extreme temperatures, may limit the feasibility of conducting reliable ELD tests, potentially delaying the testing process.

5. Complex Roof Designs

Challenge: Complex roof designs with multiple layers, penetrations, or irregularities can pose challenges for ELD testing.

Impact: The intricate nature of certain roofing designs may make it more difficult to achieve comprehensive coverage with ELD, leading to potential oversights in leak detection.

6. Training and Expertise

Challenge: Properly conducting ELD tests requires specialized training and expertise.

Impact: If the construction team lacks sufficient training, the accuracy of the tests may be compromised, leading to potential misinterpretation of results and overlooked leaks.

What's the solution?

Effective communication and coordination between the roofing contractor and the Electronic Leak Detection (ELD) testing company are essential to overcome these challenges. At Honza Group, we prioritize continuous communication with our clients to avoid any surprises upon arrival at the site. Clear communication about the requirements for testing beforehand ensures a smooth process.

Similar to conducting a job hazard analysis, Honza Group meticulously goes through a pre-arrival checklist to streamline the project for our clients. We identify any problematic details in advance to take the necessary steps to eliminate interference with testing. This includes ensuring that the area of the roof to be tested is free of materials, equipment, and debris, and that access is provided by the roofer to test all relevant areas.

While weather conditions can sometimes pose challenges, establishing parameters with the roofing contractor or client early on helps tailor expectations and plan accordingly. By fostering open communication and proactive coordination, Honza Group ensures efficient and effective ELD testing that meets the needs of our clients.
