How Capacitance Meters Find Wet Insulation On Flat Roofs After Hailstorm
A capacitance meter finds wet insulation by sensing changes in an electrical field across the roof assembly. Because water stores electrical charge differently than dry insulation, wet areas create higher capacitance readings. During capacitance roof testing, a technician scans the roof in a grid, compares readings to a dry baseline, then maps “hot spots.” Final…
