What Drying Logs Do Insurance Adjusters Actually Check?

What to take away

Most US carriers pay from the daily drying log, not the invoice. A log missing dates, readings or equipment placement gets cut or denied.
IICRC S500 sets the drying standard; Xactimate is the estimating platform adjusters read it in. Ask for both by name.
The licence that matters is the state contractor licence for the trade, plus IICRC WRT certification for the technicians on site.
Ask for the drying log on day one, not at the end. The crew that hesitates is the crew to walk away from.
Get the documentation clause into the contract before work starts, not after the invoice arrives.

Why the log decides the claim

An adjuster reads three things: what was wet, what was done, and whether it worked. A well-built drying log answers all three.

IICRC S500 requires daily moisture readings, temperature, relative humidity, equipment counts, and placement. It also requires a drying goal tied to a dry standard. Xactimate then converts those entries into line items the carrier can pay.

What a Drying Log Must Show

Daily moisture readings
Temperature and relative humidity
Equipment counts and placement
Drying goal tied to dry standard
Entries converted to Xactimate line items

A log without a dry standard is a log without a finish line. The adjuster cannot tell whether drying was complete or the crew simply stopped. That is the most common reason a final invoice gets reduced. The overview of water damage categories and drying principles is worth reading before you argue about class of loss.

Questions to ask before you sign

Use these verbatim. Write down the answers and the name of the person who gave them.

Five Questions Before You Sign

Daily log with readings, not just at end
Dry standard and how you show reaching it
Which technicians hold current IICRC WRT
State contractor licence number and qualifier
How moisture inside walls and floors is documented

"Will you send me the drying log every day, with readings, and not just at the end of the job?"
"What dry standard are you drying to, and how will you show me when you reach it?"
"Which of your technicians on my job hold current IICRC WRT certification?"
"What is your state contractor licence number, and who is the qualifier on it?"
"How do you document moisture inside walls and under floors without opening everything?"

A competent supplier answers these in plain sentences. A confident one answers with adjectives.

Evidence to request

Ask for a sample log from a closed job, with the customer name removed. You want to see dated entries, a moisture content reading per material, psychrometric readings, and equipment mapped to rooms. Thermal imaging and pin meters are the usual tools; the explanation of thermal imaging for hidden moisture shows why an infrared scan alone is not proof.

Request the certificate of insurance and the license lookup page for your state. Request the equipment list with model numbers. If the crew claims to be drying a hardwood floor in place, ask which mat system and which daily reading target.

A crew that maps moisture properly will not mind showing you how it is done. The method for mapping moisture after a water loss is a fair test of whether they understand concealed cavities.

Answers that should end the conversation

"We take photos instead of daily readings." Photos show conditions, not progress. No carrier accepts them as a drying record.
"The log is internal. Your adjuster will get it." You are the insured. You are entitled to the record that supports your claim.
"We dry until it feels dry." That is not a dry standard, and it will not survive a reinspection.
"Certification is not required in this state." True in many states, and still a reason to ask who on site is trained.

What the contract must say

Put four things in writing. The dry standard and the target readings. Daily delivery of the log to you and to the carrier. Who pays for re-drying if readings rise after equipment is pulled. And the licence number of the firm doing the work.

If the carrier later disputes the scope, the log is your evidence. Firms that handle disputes well keep the paperwork clean from day one, which is why complaint handling for restoration owners starts with the file, not the phone call. For a sense of how the work is priced around documentation, see the quote template with pricing examples.

Where the paperwork breaks down

Two failures recur. The first is a log that stops when the equipment leaves, so nobody can prove the structure reached the dry standard. The second is a log that never recorded the wet materials at all, only the rooms.

Ask how the crew will handle a category 2 or category 3 loss, where the log must also record the antimicrobial application and any removed material. Ask what happens when a homeowner turns off the dehumidifier overnight. The answer tells you whether the crew visits daily or just drops equipment.

Common questions

Does the adjuster read the drying log or the invoice?

Both, but the log comes first. The invoice is only payable where the log supports the line items. Missing days are the easiest thing for a carrier to strike.

How often should readings be taken?

Daily is the working expectation on most US residential claims. Some carriers accept less on small losses, and none accept a single reading at the end.

What if my contractor refuses to share the log?

Ask the adjuster to request it directly. If it still does not appear, that is a reason to question the invoice, and often a reason to change firms.

Is IICRC certification legally required?

No. It is a standard, not a licence. The licence that applies is your state contractor licence, which you can verify through the state board before signing.
