The Best Measure of Moisture for Water Damage Relative Humidity RH

When assessing water damage, the most reliable measure of moisture is Relative Humidity (RH), which represents the amount of water vapor present in the air relative to its maximum capacity at a given temperature.

RH is expressed as a percentage: 0% means no water vapor, while 100% indicates the air is saturated with moisture.

To determine RH, special instruments called hygrometers are used. These devices measure the temperature and moisture content of the air, providing an accurate reading of RH.

Why RH is Important for Assessing Water Damage:

• RH levels above 60% promote mold growth, posing health risks.
• Excess moisture can damage building materials, such as drywall, wood, and insulation.
• RH readings help determine the extent of water damage and guide restoration efforts.

Using RH to Assess Water Damage:

RH readings can be taken at different locations and depths within a structure to create a moisture profile. This profile allows experts to:

• Identify areas of high moisture concentration
• Assess the severity of water damage
• Estimate the drying time and resources required for restoration

Conclusion:

Relative Humidity (RH) is the most accurate measure of moisture for assessing water damage. By utilizing hygrometers to measure RH levels, experts can determine the extent of damage, monitor drying progress, and ensure the restoration process is effective.
