The short answer
What Is a Drying Log?
A drying log is a simple table that tracks moisture levels in your home's materials as they dry out after water damage. Each row lists a date and time, a specific location, and a moisture reading from a meter. The log may also include notes about equipment settings or conditions.
You might see this log on paper, a spreadsheet, or a digital dashboard. The pros use it to monitor progress and adjust their approach. For you, it is a way to see whether the drying process is moving in the right direction and when your home might be ready for repairs.
- Date and time of each reading
- Location or material type tested
- Moisture reading in percent or on a scale
- Equipment used, such as a pin-type or pinless meter
- Notes on temperature, humidity, or ventilation changes
- Any actions taken between readings, like moving equipment
How to Spot a Good Trend
Look for a general downward pattern in the moisture readings over time. If you see readings dropping from one entry to the next, the drying is working. A good log will show a gradual decline, not a sudden jump, because materials dry slowly and evenly.
Flat readings over a few days might mean the drying has stalled. Rising readings are a warning sign that more water is getting in, or the drying method is not effective. In either case, you should ask the pros to explain what is happening and what they plan to do next.
What the Numbers Mean
Moisture meters give readings in different ways. Some show a percentage of moisture content, while others use a relative scale from 0 to 100. For most building materials, a reading below 15 percent is considered dry, but the exact target depends on the material and local conditions.
Your drying log might include a target range for each material. If the numbers stay above that range for too long, the material could be at risk for mold or rot. Ask the pros what the target is for your situation, and compare each reading to that goal.
When to Ask Questions
You do not need to be an expert to read a drying log. If you see a pattern that worries you, or if the log seems incomplete, ask the pros for a clear explanation. They should be able to point to specific readings and tell you what they mean.
Also ask about the plan for the next few days. A good log will help the pros decide when to move equipment, when to stop drying, and when it is safe to begin repairs. If the log does not make sense to you, that is a reason to request more detail.
Using the Log for Your Home
Keep a copy of the drying log for your records. It can be useful when talking to your insurance company about the damage. Policies vary, and your insurer decides what is covered. The log gives you a factual record of the drying progress.
If you live in Orem, the semi-arid climate with cold snowy winters and hot dry summers can affect how quickly materials dry. That makes a consistent log even more valuable. You can compare readings from different days and see how your home responds to the local weather.

How often should the pros take moisture readings?
Readings are usually taken once or twice a day, depending on the severity of the water damage. The log should show consistent intervals. If readings are sporadic or missing, ask why. Regular readings give a reliable picture of the drying trend.
What should I do if the log shows no improvement?
If readings stay flat or rise, tell the pros right away. They may need to adjust equipment, add ventilation, or check for hidden moisture. Do not wait, because prolonged dampness can lead to mold. A good log helps catch problems early.
Can I take my own moisture readings?
You can buy a moisture meter, but reading it correctly takes practice. The pros use calibrated meters and know the right spots to test. If you want to track progress yourself, ask the pros to show you how and what numbers to expect.
