Why the Manufacturer’s Technical Inspection Report Matters

Understanding the Technical Inspection Report

In commercial roofing, the issuance of a manufacturer warranty is often preceded by a site visit from a technical representative. While many facility managers only receive the final warranty certificate, the more critical document for long-term risk management is the Manufacturer’s Technical Inspection Report.

This report is an internal document generated by the manufacturer's inspector. It details whether the installation met the specific assembly requirements of the warranted system. Unlike the warranty certificate, which is a legal agreement, the inspection report is a technical record of the roof's condition at the moment of completion.

Why This Document is Essential for Verification

  1. Identification of Exceptions: Inspectors often find minor deviations from the specification. Instead of requiring a full tear-out, the manufacturer may issue the warranty but "except out" those specific areas. Without the report, an owner may be unaware that certain sections of the roof are not actually covered.
  2. Punch-List Accountability: The report confirms whether the contractor addressed all technical deficiencies before the manufacturer accepted the risk. If a leak occurs in year three, this report serves as the baseline for determining if the issue was a latent installation defect or a post-installation event.
  3. Future Claims Defense: If a warranty claim is ever disputed, the technical inspection report is the primary evidence used to determine if the system was installed according to the approved shop drawings.

Verification Strategy

Request the full, unredacted inspection report—including any photos taken by the manufacturer’s representative—as a condition of final payment. Do not rely on the contractor's verbal confirmation that the "inspection passed." The written report provides the only objective proof of the manufacturer’s satisfaction with the workmanship.
