Get expert forensic roof investigations to identify causes of roof failure, moisture intrusion, and construction defects. Serving MN, IL, and WI.

When roofing systems fail unexpectedly, you need more than a quick fix—you need answers. Our Forensic Roof Investigation Services provide a structured, evidence-based approach to discovering the root cause of roof issues. Whether you’re facing persistent leaks, warranty disputes, or legal claims, our expert team delivers clarity and actionable insight.

What is a Forensic Roof Investigation?

Forensic roof investigation is the scientific analysis of roofing failures, designed to determine what went wrong and why. Our consultants combine site inspection, material sampling, moisture testing, and document review to identify defects in design, materials, installation, or maintenance practices.

When Do You Need Forensic Roof Analysis?

  • Leaks persist despite multiple repairs
  • New installations fail prematurely
  • Warranty or insurance disputes require evidence
  • Legal cases demand expert witness documentation
  • You need unbiased third-party verification

Our Forensic Roof Investigation Services Include:

  • Infrared thermal scanning and moisture detection
  • Core sampling and lab-based material analysis
  • Review of contractor workmanship and specifications
  • ASTM-compliant field testing for air and water infiltration
  • Expert witness reports and litigation consulting

Common questions

How is a forensic roof investigation different from a roof inspection?
A roof inspection documents current condition and remaining service life. A forensic investigation starts from a known failure or dispute and works backward to cause, using document review, exploratory openings, core samples and testing. It produces an evidentiary record intended to be relied on by a warranty administrator, insurer or attorney, not just a maintenance to-do list.
Will the investigation damage my roof?
Exploratory openings and cores do cut into the assembly, and that is often the only way to confirm what was actually built. Openings are limited to what the investigation requires, located deliberately based on document review and moisture survey results, documented photographically, and temporarily sealed. We discuss the proposed number and location with you before field work begins.
Can INSPEC serve as an expert witness?
Yes. Our consultants can remain involved after the report is issued, including expert witness work in roofing disputes. Because we are consulting engineers and architects rather than a roofing contractor, our findings are not connected to selling the repair work that follows, which matters when opinions are examined by other parties.
Should I repair the roof before the investigation?
Where possible, wait. Repairs can remove or obscure the conditions an investigation depends on. If leaks require emergency action to protect the interior, tell us before the work happens so the affected areas can be photographed and documented, and ask the contractor to retain any removed materials rather than discard them.
