Supplemental Claim Definition
A supplemental claim (also called a supplemental insurance claim or supplement) is an additional claim filed after your initial claim when previously undiscovered damage is found or when the original estimate was insufficient to cover actual repair costs. Supplemental claims request additional payment beyond the initial settlement.
In simple terms: A supplemental claim is when you go back to your insurance company and say, “We found more damage” or “This costs more than your estimate.”

When to File a Supplemental Claim
Supplemental claims are appropriate when legitimate additional damage or costs arise that weren’t included in your original claim settlement.
Valid Reasons for Supplemental Claims
1. Hidden Damage Discovered During Tear-Off
The most common reason for supplemental claims. Damage that wasn’t visible during the initial inspection becomes apparent once work begins:
- Rotted roof decking hidden beneath shingles
- Water damage to underlying structure
- Damaged or missing underlayment
- Compromised rafters or trusses
- Additional storm damage not visible from surface
2. Scope Gaps in Original Estimate
The insurance adjuster’s estimate missed or underestimated necessary work:
- Insufficient quantities of materials
- Missing line items (flashing, drip edge, ice and water shield)
- Underestimated labor requirements
- Code upgrades required but not included
- Additional collateral damage (gutters, vents, siding)
3. Material Price Increases
If significant time has passed between the estimate and actual work, material costs may have increased beyond the original settlement.
4. Code Compliance Requirements
Building department requirements discovered during permit process that weren’t in the original scope:
- Additional ventilation required
- Upgraded flashing specifications
- Ice and water shield coverage beyond minimum
- Structural reinforcement needed for code compliance
Common Supplemental Claim Situations in Colorado Springs
Situation #1: Rotted Decking Discovered During Tear-Off
What happens: The adjuster inspects from the roof surface and doesn’t see decking issues. During tear-off, the contractor discovers extensive rotted or damaged decking that wasn’t visible.
Why it’s common in Colorado Springs:
- Hail damage can compromise shingles, allowing water infiltration
- Previous roof damage or leaks may have caused hidden deterioration
- Ice damming in winter causes moisture problems
- Inadequate ventilation leads to condensation and rot
Insurance company response: Often claim it’s “pre-existing” and deny coverage. However, if the storm caused or significantly worsened the damage, it should be covered.
Typical supplemental amount: $3,000-$15,000 depending on extent of decking replacement needed.
Situation #2: Missing Line Items in Original Estimate
What happens: The adjuster’s Xactimate estimate doesn’t include all necessary components for a complete, code-compliant roof replacement.
Commonly missed items:
- Drip edge: Required by Colorado building code but sometimes not in estimates
- Ice and water shield: Underestimated coverage area
- Pipe boot replacements: All boots should be replaced during re-roof
- Ridge vent: Proper ventilation requirements
- Step flashing: At wall intersections
- Valley metal: For open valley installations
- Starter shingles: Required at eaves and rakes
Typical supplemental amount: $1,500-$5,000 for missing line items.
Situation #3: Collateral Damage Not Fully Assessed
What happens: The initial claim focused on the roof, but the same storm damaged gutters, siding, windows, or other components that weren’t fully documented.
Example:
- Original claim: Roof only ($25,000)
- Supplemental claim adds: Gutters ($3,500), damaged siding ($6,000), window screens ($800)
- Total supplemental: $10,300
Key point: This should ideally be caught during the initial claim, but if missed, supplemental claims can address it.
Situation #4: Unforeseen Structural Issues
What happens: Structural problems discovered once roofing materials are removed:
- Damaged or broken rafters from hail impact
- Sagging roof structure requiring reinforcement
- Storm damage to roof framing not visible from surface
- Compromised chimney structure
Typical supplemental amount: $2,000-$20,000+ depending on structural repairs needed.
How to File a Supplemental Claim
Filing a successful supplemental claim requires proper documentation and strategic presentation.
Step 1: Document the Additional Damage or Costs
Before work proceeds, photograph everything:
- Wide shots: Overall area showing extent of newly discovered damage
- Close-ups: Detailed photos of specific issues (rotted decking, damaged structure, etc.)
- Measurement reference: Include tape measures or markers showing scale
- Multiple angles: Document from different perspectives
- Before during after: Initial condition, damage exposed, completed repair
Critical timing: Take photos immediately when damage is discovered, before any additional work is done.
Step 2: Get Contractor Documentation
Your contractor should provide:
- Written report: Detailed description of discovered damage
- Photographic evidence: Professional photos with annotations
- Supplemental estimate: Xactimate estimate for additional work needed
- Signed statement: Certifying damage wasn’t visible during initial inspection
- Code requirements: Documentation of any code-related additions
Step 3: Notify Insurance Company Immediately
Contact your adjuster as soon as additional damage is discovered:
- Call and follow up with written notice (email or portal)
- Reference your original claim number
- Briefly describe the newly discovered damage
- Request re-inspection or provide opportunity for them to inspect
- Ask about their supplemental claim process and requirements
Sample notification:
“This is to notify you that during the tear-off process on [date], our contractor discovered rotted decking that was not visible during your initial inspection. We are requesting a supplemental claim to cover this additional damage. Photos and contractor documentation are attached. Please advise on next steps for inspection and processing this supplement. Original claim number: [claim #].”
Step 4: Request Re-Inspection (If Necessary)
Some insurance companies require an adjuster to inspect supplemental damage in person. Others accept contractor documentation and photos.
Tips for supplemental inspections:
- Stop work: Don’t repair the discovered damage until after adjuster inspection (if required)
- Be present: Attend the re-inspection to answer questions
- Provide context: Explain why this damage wasn’t visible initially
- Show progression: Walk adjuster through original condition → tear-off → discovered damage
- Have documentation ready: Photos, contractor report, estimates immediately available
Step 5: Submit Formal Supplemental Claim
Once documentation is complete, submit your supplemental claim package:
- Cover letter: Explaining the supplemental claim and referencing original claim
- Photographic evidence: All relevant photos with captions/dates
- Contractor documentation: Written report, estimate, signed statements
- Comparison: Original estimate vs. actual discovered conditions
- Technical justification: Explanation of why damage wasn’t visible initially
- Code references: If applicable, cite specific code requirements
Step 6: Follow Up and Negotiate
Insurance companies often initially deny or partially approve supplemental claims.
If denied or undervalued:
- Request detailed explanation of denial reasons
- Address each denial reason with additional documentation
- Cite policy provisions supporting coverage
- Escalate to supervisor if adjuster is unreasonable
- Consider professional claim advocacy or public adjuster if large amount at stake
Required Documentation for Supplemental Claims
Strong documentation is critical for supplemental claim approval. Here’s what you need:
Photographic Evidence
Minimum photo requirements:
- 10-15 photos minimum showing discovered damage from multiple angles
- Date stamps visible (or documented in file metadata)
- Clear, well-lit images (not blurry or too dark)
- Context shots: Wide views showing location on roof
- Detail shots: Close-ups showing specific damage
- Measurement references: Tape measures, markers showing scale
- Before conditions (if available): Original inspection photos for comparison
Contractor Documentation
Essential contractor documents:
- Signed statement: Certifying damage was not visible during original inspection
- Detailed description: Technical explanation of discovered damage
- Xactimate supplement: Professional estimate matching insurance format
- Scope comparison: Original approved scope vs. actual discovered needs
- Timeline documentation: When damage was discovered during project
Technical Justification
Explain why damage wasn’t discovered initially:
- “Decking damage was concealed beneath intact shingles and not visible until tear-off”
- “Water damage to underlayment only became apparent when roofing materials were removed”
- “Structural damage to rafters was hidden by roof decking and sheathing”
- “Code requirements were identified during building department review, after initial estimate”
The key is proving this isn’t something that should have been caught initially—it was genuinely hidden or unknown.
Supporting Evidence
- Building permits: If code upgrades required
- Material receipts: Showing actual costs for price increase claims
- Manufacturer specifications: If original estimate didn’t meet product requirements
- Weather reports: For claims about storm-related concealed damage
Common Supplemental Claim Challenges and Denials
Challenge #1: “Pre-Existing Damage” Denial
The claim: “This damage existed before the storm and should have been discovered during the initial inspection.”
Insurance company perspective: They’re suspicious that contractors are inflating damage or claiming pre-existing issues as storm-related.
How to challenge:
- Document that damage was concealed and not visible during surface inspection
- Show relationship between storm damage and discovered issues (e.g., hail compromised shingles → water infiltration → decking rot)
- Provide contractor statement certifying damage discovery timeline
- Reference similar claims in your area from the same storm
- Cite policy language on “discovered damage during covered repairs”
Challenge #2: “Contractor Should Have Seen This” Denial
The claim: “A competent contractor would have identified this during their initial estimate.”
How to challenge:
- Explain what specifically concealed the damage (intact shingles, decking, etc.)
- Industry standard practice doesn’t require destructive inspection for estimates
- Contractors cannot see through roof materials without removal
- Even insurance adjusters didn’t identify it during their inspection
Challenge #3: Scope Dispute
The claim: “This work isn’t necessary” or “This exceeds what’s required for proper repair.”
Common disputes:
- Amount of decking replacement needed
- Whether full replacement vs. repair is appropriate
- Extent of code upgrade requirements
- Necessity of certain materials or components
How to resolve:
- Get building inspector documentation if code-related
- Provide manufacturer installation requirements
- Reference industry best practices
- Show why partial repair won’t work (warranty issues, matching problems, etc.)
Challenge #4: Timing Issues
The claim: “You should have filed this with the original claim” or “Too much time has passed.”
How to address:
- Document exactly when damage was discovered
- Show you notified insurance promptly after discovery
- Explain why delay occurred (weather, contractor scheduling, etc.)
- Cite policy provisions—most don’t have strict supplemental claim deadlines
Timing and Deadlines for Supplemental Claims
When to File
Ideal timing: As soon as additional damage is discovered, before continuing work.
Acceptable timing: Within days or weeks of discovery, with documentation explaining any delay.
Problematic timing: Months after work is complete, with no photographic evidence of discovered damage.
Statute of Limitations
Supplemental claims typically fall under the same statute of limitations as the original claim:
- Colorado general rule: 1-2 years from original date of loss (the storm date, not the discovery date)
- Policy-specific deadlines: Check your policy for claim filing deadlines
- Practical limit: Insurance companies become more skeptical the longer you wait
Best practice: File supplemental claims within 3-6 months of the original claim for best results.
Work Stoppage During Supplemental Process
Question: Should you stop work when supplemental damage is discovered?
Answer: It depends on your insurance company’s requirements:
- If re-inspection required: Stop work, preserve evidence, wait for adjuster
- If documentation accepted: Photograph thoroughly, document, then proceed (verify with adjuster first)
- If emergency repairs needed: Mitigate damage, document everything, notify insurance immediately
Always ask your adjuster: “Do you need to inspect this in person, or can we proceed with photographic documentation?”

Result: American Family approved $8,500 supplement after structural documentation provided.
Common Questions About Supplemental Claims
Can I file a supplemental claim after my roof is already completed?
Yes, but it’s much more difficult. Without photographic evidence of the discovered damage, insurance companies are highly skeptical. If you’ve already completed work without documenting additional damage, your chances of successful supplemental approval are low.
Always photograph discovered damage before covering it up or completing repairs.
How many supplemental claims can I file?
There’s no specific limit, but insurance companies become increasingly skeptical with each additional supplement. Ideally:
- First supplement: Usually accepted if properly documented
- Second supplement: Requires strong justification
- Third+ supplements: Face heavy scrutiny; may indicate inadequate initial assessment
Best practice: Conduct thorough inspections to catch all issues in one or two supplements maximum.
Do I pay my deductible again for supplemental claims?
No. Your deductible applies once per claim event. Supplemental claims are part of the same original claim, so no additional deductible is charged.
Example:
- Original claim: $25,000 (you paid $2,000 deductible)
- Supplemental claim: $8,000 (no additional deductible)
- Total claim: $33,000 (you paid $2,000 deductible total)
What if my insurance company denies my supplemental claim?
You have several options:
- Request detailed denial explanation: Understand specific reasons
- Provide additional documentation: Address each denial reason
- Request re-inspection: Have adjuster see damage in person if they haven’t
- Escalate to supervisor: Sometimes line adjusters are too conservative
- Invoke appraisal clause: If dispute is about damage extent, not coverage
- Hire professional advocacy: Roof consultant or public adjuster
- File complaint: Colorado Division of Insurance if denial seems unreasonable
- Legal action: Last resort if significant amount at stake
Can my contractor file the supplemental claim for me?
Contractors can prepare documentation and estimates, but you (the policyholder) must file the claim. The contract is between you and your insurance company, not your contractor.
Contractor’s role:
- Document discovered damage
- Prepare supplemental estimates
- Provide technical justification
- Attend re-inspections with you
- Communicate findings to you
Your role:
- Submit claim to insurance company
- Communicate with adjuster
- Make final decisions
- Sign documents
Will filing a supplemental claim increase my premiums or affect future coverage?
Supplemental claims are part of your original claim, not separate claims. They don’t count as an additional claim on your record.
Impact on premiums:
- Supplements don’t create additional claim history
- Your original claim (whether $25,000 or $33,000 with supplement) is one claim
- Premium increases depend on original claim, not supplemental amounts
