How to Inspect for Attic Moisture Intrusion

When the inspector is in the attic checking for moisture intrusion is extremely important and something that the clients/agents will want to know. The inspector should check for any signs of moisture, mold, or white paint that could be concealing moisture damage. Please review the entire procedure below.

Axium SOP Differences

Axium Requires: The inspector should check for any moisture intrusion and possible mold while in the attic.

 

Tools Needed

The inspector might need a flashlight and the moisture meter to determine if there is any active moisture intrusion in the attic.

Procedure

  • While the inspector is viewing the attic (while walking or from the entrance) they shall inspect for any moisture intrusion. There are no pictures required for this section unless moisture intrusion is found in the attic.

  • Visible signs of water intrusion in the attic can be seen on stained ceiling drywall in home. Stain could be from a previous leak that happened before a newer roof was installed. Water intrusion can lead to costly repairs and damage if it is not corrected. Make sure to note in your report if you see white paint since that can be used to conceal moisture and/or mold.

 

Common Defects

  • Signs of water intrusion on insulation, rafters, sheathing, or a vent pipe.
  • Possible mold-like substance in the attic.

 

Common Mistakes

  • Not using the moisture meter to determine if there is active moisture in the attic.
  • Not checking throughout the entire attic for signs of moisture intrusion.
  • Not looking for possible mold-like substances when there is moisture intrusion.
