Quality Assurance in Action: Safeguarding Insulation Integrity

By Benchmark Inc. 

In roofing, taking the right approach saves time while enhancing both safety and quality. 

During a routine site visit, our Benchmark field consultant witnessed a troubling scene: a roofing crew, after battling harsh weather conditions, attempted to install insulation over ice. Their improvised efforts to remove it were not only ineffective but also damaging. What followed was an immediate intervention, a stop-work order and a critical inspection that revealed more problems than just the ice. The story of how quick action prevented long-term roofing failures is one you can’t afford to miss. 

Solution 

As experts in quality control, we stepped in immediately, halting work and instructing the crew to dismantle the compromised work (approximately 80 to 100 squares). Upon doing so, we discovered several other issues from significant gaps in the insulation, wet and/or damaged insulation, loose fasteners, poorly welded plates and missing induction welds. After tear-off, the crew then properly installed 38 squares, facilitating the correct installation of a roofing system over a prepared, dry area. 

Possible impact 

Without Benchmark's intervention, these issues may have gone undetected. If the initial installation had proceeded, the underlying ice and snow would eventually have melted, causing leakage and trapping moisture within the insulation. By identifying and rectifying these issues early, we've ensured a high-quality finish, preventing potential future problems.
