Why Insurance Adjusters Care About Daily Drying Logs
A daily drying log isn't just busywork—it's your proof that you monitored the job properly, adjusted when needed, and dried the structure to standard. But most contractors waste time documenting things adjusters don't care about while missing what they actually need to see.
The adjuster's question:
"Did you actually monitor this job daily, or did you just set equipment and come back a week later?"
The 5 Essential Components of Every Daily Drying Log Entry
Date, Time, and Technician Name
Every entry needs a timestamp and the name of who took the readings. This proves someone was physically on-site.
Day 3 - Tuesday, May 14, 2024 - 10:30 AM
Technician: Mike Johnson
Ambient Temperature and Relative Humidity
Measure the air conditions in the affected area. This shows the drying environment you created.
Living Room: 76°F / 32% RH
Kitchen: 74°F / 35% RH
Pro tip: You want to see RH dropping over time. If it's not, you need to adjust equipment.
Material Moisture Content by Location
This is the heart of your drying log—the data that proves materials are actually drying. Show the trend.
Living Room - North Wall (drywall): 22% → 18% → 15%
Living Room - Hardwood floor: 14% → 12% → 10%
Kitchen - Subfloor under vinyl: 28% → 25% → 21%
Equipment Status and Any Changes Made
Note what equipment is running and any adjustments made based on conditions.
Equipment running: 3 air movers, 1 LGR dehumidifier
Change: Added 1 additional air mover to north wall (readings slower than expected)
All equipment checked and operating properly
Observations and Progress Notes
Brief notes about what you observed and the overall drying progress.
Visible moisture decreasing on north wall. Subfloor drying as expected. Customer reported no musty odors. All areas responding well to equipment.
What NOT to Waste Time Documenting
Overly detailed narratives
"Arrived at property at 10:23 AM, walked through front door, greeted customer..." Adjusters don't need a novel. Keep it concise.
Duplicate information
Don't repeat the same equipment list every day if nothing changed. Just note "Equipment unchanged" unless you made adjustments.
Irrelevant customer conversations
Focus on drying progress, not what the customer said about their vacation plans.
Complete Daily Log Example (Day 3 of Mitigation)
Water Loss - 123 Oak Street - Day 3
Date: Tuesday, May 14, 2024
Time: 10:30 AM
Technician: Mike Johnson
Ambient Conditions:
Living Room: 76°F / 32% RH
Kitchen: 74°F / 35% RH
Moisture Readings:
Living Room - North Wall (drywall): Day 1: 22% → Day 2: 18% → Today: 15%
Living Room - Hardwood floor: Day 1: 14% → Day 2: 12% → Today: 10%
Kitchen - Subfloor: Day 1: 28% → Day 2: 25% → Today: 21%
Equipment:
Running: 3 air movers, 1 LGR dehumidifier
Change: Added 1 air mover to north wall area (readings progressing slower than expected)
Notes:
All materials showing steady drying progress. North wall readings improving but slightly behind other areas—adjusted equipment placement. Customer satisfied with progress. No odors detected. Estimate 2-3 more days to reach dry standard.
Common Daily Log Mistakes That Delay Payment
Mistake: Vague readings
❌ Bad:
"Walls getting drier"
✓ Good:
"North wall: 15% (down from 22%)"
Mistake: No trend documentation
❌ Bad:
"Reading today: 18%"
✓ Good:
"18% (Day 1: 24% → Day 2: 21%)"
Mistake: Missing days
If you bill for 5 equipment days but only have logs for 3 days, the adjuster will question whether you actually monitored daily. Fill gaps immediately or expect payment delays.

Frequently Asked Questions
What should every daily drying log entry include?
Every entry needs five essential components: date, time, and technician name; ambient temperature and relative humidity by area; material moisture content readings by location with trends; equipment status and any changes made; and brief observations about drying progress.
Why do insurance adjusters care about daily drying logs?
Daily logs prove you followed IICRC S500 guidelines for ongoing monitoring. They show you monitored conditions daily, made adjustments based on readings, achieved dry standard through documented progress, and that your equipment days and technician time were legitimately spent on active monitoring.
How should I format moisture readings in drying logs?
Document actual moisture readings by specific location showing the trend over days. For example: 'Living Room - North Wall (drywall): Day 1: 22% → Day 2: 18% → Today: 15%'. This shows adjusters the drying progress clearly.
What information should I NOT include in drying logs?
Avoid overly detailed narratives about your day, duplicate information (just note 'equipment unchanged' unless adjustments were made), and irrelevant customer conversations. Focus on drying progress data, not storytelling.
What daily log mistakes delay payment?
Common mistakes include vague readings like 'walls getting drier' instead of specific percentages, single-day readings without trend comparison to previous days, and missing days—if you bill for 5 equipment days but only have 3 days of logs, expect payment delays.
