 Benefits of Moisture Mapping for Flat Roofs

The benefits of moisture mapping extend beyond its ability to identify moisture intrusion and determine the extent of roof repair. By providing precise information on the roof’s condition, moisture mapping supports effective decision-making, helping clients allocate resources where they are most needed. It aids in prioritising maintenance and repair efforts, allowing for targeted interventions that prevent further damage.

Moisture mapping utilises a sophisticated technique that measures the thermalisation (slowing down) of emitted neutrons, enabling the detection of hydrogen and moisture content in the majority of roof build-ups.  It’s important to note that roofing materials inherently contain hydrogen, so to establish a reliable baseline, core samples are analysed from various gauge reading locations (low-high) to determine the extent to which thermalisation is caused by trapped moisture.

Key Features of the Testing Method:
Moisture mapping sets a scientific foundation for informed decision-making, relying on accurate information rather than assumptions or opinions. It proves particularly valuable when assessing multiple roof systems, including those that have already been overlaid and roofs with multiple layers of insulation. With the capability to penetrate up to 300mm, moisture mapping provides a comprehensive analysis. The method applies to the majority of waterproofing systems.

Measurements are typically conducted in a 2-meter grid pattern, meticulously plotted on a scaled roof drawing. After collecting the readings, a histogram is generated, facilitating the identification of dry and wet areas.

Versatility in Roof Analysis:
Moisture mapping is well-suited for analysing various roof structures, especially those with multiple insulation layers and previous waterproofing systems. It can also detect moisture within decks or supporting structures when roofs are uninsulated. By employing this technique, roofing professionals gain valuable insights into the moisture distribution across the roof surface, enabling targeted repairs and proactive maintenance measures.

In conclusion, moisture mapping potentially unveils the hidden secrets of flat roofs, providing precise and scientific information for decision-making. With its ability to accurately analyse multiple roof systems and penetrate various layers of insulation, this technique is invaluable in assessing moisture content and guiding effective roof repair strategies.
