What is the use of moisture meters in roof inspections?

Moisture meters are essential tools used in roof inspections specifically to assess moisture levels within roofing materials. Roofs can suffer from hidden water damage due to leaks or poor drainage that may not be visible to the naked eye. By measuring the moisture content within materials like insulation, sheathing, and roofing membranes, inspectors can pinpoint areas where water has infiltrated, leading to potential mold growth, decay, or a compromised structural integrity of the roof system.

This function is critical in determining the condition of the roof and whether repairs or further investigation are necessary. Accurate moisture readings help in identifying existing problems before they escalate, thus aiding in preserving the overall health of the roofing system. In contrast, measuring surface temperature, assessing structural integrity, or determining the age of roofing materials does not directly provide insight into hidden moisture issues, which is the primary concern addressed by moisture meters.
