Sample Supplement Letter

Dear Claims Adjuster,

We are writing to provide additional information and request consideration regarding the recent claim assessment.

Re: Roof Replacement Supplement Request
Property Address: 123 Main Street, Anytown, TX 75001
Claim Number: ABC-123456
Date of Loss: March 15, 2024

We are writing to supplement our original estimate and request approval for a complete roof replacement rather than the proposed repair. After careful evaluation of the existing roofing materials and applicable building codes, we have determined that a partial repair would not meet current building standards and could potentially void manufacturer warranties.

Building Code Compliance Requirements:

According to the International Residential Code (IRC), specifically Section R908.3.1.1, when removing existing roof coverings down to the roof deck as part of a reroofing project, the roof deck must be examined and repaired or replaced as necessary. This requirement makes partial repairs impractical and potentially non-compliant.

Additionally, IRC Section R905.2.7.1 limits the number of roof covering layers to a maximum of two. The existing roof structure would require complete evaluation to ensure compliance with current codes.

Product Discontinuation and Matching Issues:

The existing Atlas Chalet shingles were discontinued on 2018-06-01. Product line discontinued due to manufacturing changes. This creates several critical issues:

1. Exact Color/Texture Matching: Discontinued products cannot be matched exactly, resulting in visible patchwork that diminishes property value

2. Manufacturer Warranty Void: Mixing old and new materials typically voids manufacturer warranties

3. Insurance Compliance: Most carriers require matching materials or full replacement when exact matches are unavailable

Recommended replacement options include: Atlas StormMaster Slate, Atlas Pinnacle Pristine.

Professional Recommendation:

Based on our professional assessment and detailed estimate, we recommend proceeding with a complete roof replacement to ensure:

- Full compliance with current building codes
- Maintained manufacturer warranty coverage
- Uniform appearance and property value preservation
- Long-term weather protection and durability

We appreciate your professional consideration of these technical requirements and look forward to your response.

We respectfully request your reconsideration of the repair-only approach and approval for the complete roof replacement as outlined in our supplemental estimate.

Thank you for your prompt attention to this matter.

Sincerely,

John Smith
