Flat Roof Leak Detection

Your building’s roof is continuously fighting to keep rain water and melted snow from entering the interior of your building. It’s a critical part of protecting your property and anyone inside your building. But, inevitably your roof will start to fail after constant exposure to the elements. Roof damage can be incredibly difficult to pinpoint, but doing so is critical for cost-effective repairs.

Below, we’re going to discuss low-voltage electronic leak detection otherwise referred to as LVEIT or EFVM (Electric Field Vector Mapping), when it’s useful, and why it could be the best roof testing solution for your building.

What Is Low-Voltage Electronic Leak Detection (EFVM)?

Low-voltage leak detection is a method of roof testing that uses electrical readings to pinpoint roof damage. The flat roof is covered with a thin layer of water, a ground is connected to a convenient portion of the building, and charged probes are passed through the water layer.

Any leak in your roof, however small, will allow water into your building material, which will create a pathway for the electrical impulses to travel between the probes and the ground. Voltage differentials are picked up as the roof is scanned and can then be interpreted to determine the exact locations of roof leaks.

When Is it Used?

This kind of testing is used for flat roofs that are suspected to be leaking and as a precautionary testing method to determine if roof leaks are present. It’s useful for all types of flat and low-sloped roofs, and it uses a fraction of the water that flood testing uses, so it’s far less likely to damage your structure.

Benefits of Low-Voltage Leak Detection

Many building owners turn to low-voltage solutions for a variety of reasons. As mentioned above, it is unlikely to cause structural damage to your building like flood testing can, given the small amount of water needed. It also won’t force water through your roof to your building’s interior like flood testing is designed to do.

Additionally, low-voltage testing can provide very accurate mapping of all breaches in the waterproofing membrane. You can use it to pinpoint damage which prevents having to carry out major repairs or full roof replacements. Low-voltage testing is a non-invasive and affordable way to get accurate readings of areas of your roof that may be leaking. It can help you minimize repair costs, determine if a replacement is necessary, and give you peace of mind knowing that you’ve repaired even the smallest of leaks.
