Common Mistakes in Supplementing Roofing Insurance Claims

Supplementing roofing insurance claims is a critical process for ensuring contractors are fully compensated for the work required to restore a property. However, even small mistakes can lead to underpaid claims, delayed approvals, or outright denials. This guide uncovers frequent supplementing errors and provides actionable strategies to secure timely approvals and maximize payouts.

Why Avoiding Mistakes Matters

Mistakes in supplementing don’t just affect a single job; they can damage your reputation, waste valuable time, and lead to lost revenue. By recognizing these common pitfalls, contractors can protect their bottom line, build trust with insurance adjusters, and streamline their operations.

Common Supplement Filing Mistakes

Mistake 1: Incomplete or Inaccurate Documentation

One of the most frequent mistakes contractors make is failing to provide clear and comprehensive documentation. Without sufficient evidence, insurance adjusters may question the validity of your supplement request.

How to Avoid It:

  • Take Detailed Photos: Capture before-and-after images of all damages, ensuring clear angles and proper lighting.

  • Include Supporting Evidence: Provide measurements, material costs, and references to building codes to justify your supplement.

  • Organize Your Files: Use folders or software to group documentation by job and damage type for easy access.

Pro Tip: Annotated photos that highlight specific damages can make a significant difference in getting supplements approved.

Mistake 2: Delayed Submission of Supplements

Time is critical when dealing with insurance claims. Submitting supplements late can delay the entire process and reduce your chances of approval.

How to Avoid It:

  • Set Internal Deadlines: Ensure your team submits supplements within 24–48 hours of discovering additional damages.

  • Use Technology: Leverage software like Xactimate to streamline estimate creation and submission.

  • Communicate Early: Proactively communicate supplement needs to adjusters to streamline approvals and minimize delays.

Mistake 3: Overlooking Code-Required Upgrades

Local building codes often require upgrades that may not be included in the initial insurance estimate. Missing these can lead to compliance issues and out-of-pocket expenses.

How to Avoid It:

  • Research Local Codes: Stay updated on state and municipal requirements for roofing materials and installation practices.

  • Include in Your Estimate: Reference specific codes in your supplement to justify additional costs.

Pro Tip: A well-documented code-required upgrade is hard for adjusters to dispute.

Mistake 4: Using Generic or Incomplete Estimates

Submitting vague or incomplete estimates can confuse adjusters and slow down the approval process.

How to Avoid It:

  • Be Specific: Itemize all materials, labor, and additional costs like overhead and profit (O&P).

  • Double-Check for Accuracy: Ensure measurements and quantities are precise to avoid discrepancies.

  • Leverage Software: Use Xactimate to create detailed, professional estimates that align with industry standards.

Mistake 5: Poor Communication with Adjusters

Miscommunication can lead to misunderstandings or mistrust, jeopardizing the approval of your supplement.

How to Avoid It:

  • Stay Professional: Use clear, factual language in all communications.

  • Confirm in Writing: Follow up verbal discussions with written confirmations to avoid misinterpretation.

  • Keep a Log: A well-maintained communication log can help track interactions and clarify misunderstandings.

  • Build Relationships: A respectful, professional rapport with adjusters can pave the way for smoother interactions.
