How to Complete a Proof of Loss for Your Insurance Claim in Missouri
You've filed an insurance claim in Missouri after property damage. Your adjuster has completed their inspection. Now your insurance company sends a form titled "Proof of Loss" and asks you to complete it. Many homeowners and business owners in St. Louis and Illinois don't realize how critical this single document is—or how a poorly completed proof of loss can delay, reduce, or even result in claim denial.
The proof of loss is not just paperwork. It's a legal document that formally establishes what you're claiming was damaged and how much those damages cost. Insurance companies use it to validate your claim and determine their liability. Completing it correctly protects your rights and strengthens your settlement position.
What Is a Proof of Loss?
A proof of loss is a legal statement. You're certifying (under oath or affirmation) that you've suffered a loss covered by your insurance policy. The document typically requires you to:
- Describe the incident that caused the damage (hail storm, water damage, fire, etc.)
- List all items or areas damaged
- Provide the cost to repair or replace each item
- Explain the cause and date of loss
- Attest that the information is accurate and truthful
Insurance companies use the proof of loss as evidence of the claim's validity. If information in your proof of loss contradicts what you told the adjuster, or if your estimates seem unreasonably high or low, the insurer may question your claim's credibility.
When Is a Proof of Loss Due?
Missouri insurance law requires you to submit a proof of loss within specific timeframes. According to Mo. Rev. Stat. § 375.936, most homeowners policies require proof of loss to be filed within:
- 60 days of the loss (this is the most common deadline)
- Longer periods (90–120 days) in some policies for complex claims involving multiple damage locations
- Your policy may specify a different deadline—check your declarations page
If you miss this deadline, your insurer can deny your claim. Some insurers will request an extension, but don't count on it. File your proof of loss promptly.
What Should You Include in Your Proof of Loss?
A complete proof of loss needs detail. Here's what to include for each damaged area or item:
Property Information and Loss Details
- Your name, policy number, and contact information
- Date and time of the loss
- Cause of loss (named storm, hail, fire, water damage, etc.)
- Brief description of how the damage occurred
- Weather conditions (if relevant—hail size, wind speeds)
Itemized Damage List
Don't just write "roof damage—$20,000." Break it down:
- Location: "Master bedroom roof, south slope" or "Kitchen ceiling"
- Item damaged: "Asphalt shingles," "drywall," "hardwood flooring"
- Extent of damage: "Approximately 800 sq ft of roof with hail-induced granule loss and soft spots" or "Water damage to 60% of kitchen ceiling with mold risk"
- Repair/replacement cost: From contractor estimates (include those estimates with your proof of loss)
- Date observed: When you first noticed the damage
Supporting Documentation
Your proof of loss should be accompanied by:
- Detailed photos and video of all damage
- Written repair estimates from licensed contractors
- Receipts for emergency repairs or temporary measures (tarping, cleanup)
- Proof of ownership for damaged personal property
- Any expert assessments (structural engineer report, environmental consultant, etc.)
- Documentation of secondary damage (water damage to interior, mold, etc.)
Common Mistakes to Avoid When Filing Proof of Loss
Mistake #1: Underestimating Damage
Some homeowners list only obvious damage and miss hidden or secondary damage. After property damage in St. Louis, comprehensive documentation is critical. Water damage, mold risk, and structural issues often emerge after the initial inspection. Include these in your proof of loss based on contractor assessments.
Mistake #2: Providing Incomplete Estimates
Vague cost estimates hurt your credibility. Use detailed contractor quotes that itemize labor, materials, permits, and waste removal. The more specific, the harder it is for the insurer to dispute your numbers.
Mistake #3: Filing Without Contractor Documentation
Never file a proof of loss with only your own cost estimates. Licensed contractor quotes carry weight with insurance companies. If your estimates significantly exceed the insurer's initial assessment, contractor quotes explain the difference.
Mistake #4: Inconsistency With What You Told the Adjuster
If you told the adjuster "the storm hit on May 20" but your proof of loss says "May 19," the insurer will question your reliability. Coordinate with your documentation carefully. Review what you said during the inspection before filing.
Mistake #5: Missing the Deadline
The 60-day deadline is firm in most Missouri policies. Calendar it. Set a reminder. An insurer can legally deny a claim simply because proof of loss wasn't filed on time, regardless of whether the damage is legitimate.
How to Structure Your Proof of Loss Document
Format matters. Use a clear, professional structure:
- Header: Policy number, claim number, date filed
- Loss summary: One paragraph describing the incident
- Itemized damage: Organized by location (roof, siding, interior, etc.) or by room
- Cost summary: Total damage amount and itemized breakdown
- Attachments: Reference the contractor quotes, photos, and supporting documents
- Certification: A statement that the information is true and accurate, signed and dated
Should You Include an Appraisal or Expert Assessment?
If you've had an independent appraisal, structural engineer report, or environmental assessment done (common for complex claims), include these in your proof of loss. They strengthen your position significantly, especially if the insurer's initial estimate differs from professional assessments.
What Happens After You File Your Proof of Loss?
Once you submit it, the insurance company has several options:
- Accept it: The insurer agrees your documented damage is covered and will pay your claim
- Request clarification: They ask for more documentation or explanation on specific items
- Dispute it: They disagree with your damage assessment or claim values (this triggers appraisal if you can't agree)
- Request amendments: They ask you to revise or correct information
Missouri law requires the insurer to acknowledge receipt of your proof of loss and provide written explanation if they deny any portion of your claim.
When to Call a Public Adjuster
Consider hiring a public adjuster if:
- Your claim involves extensive damage across multiple areas of your home or business
- The insurer's assessment significantly differs from contractor estimates
- You're uncertain how to properly document and value all damage
- You need professional support drafting a compelling, well-documented proof of loss
- Your initial claim was denied and you're filing an appeal
A public adjuster conducts comprehensive inspection, obtains professional estimates, and drafts a proof of loss that positions your claim for maximum recovery. This is especially valuable in commercial property damage and complex claims in St. Louis and Missouri.
