The value of independent verification for roofing performance

By The Coffee Shops™. 

Verified testing and code compliance can help reduce risk and improve project outcomes. 

For contractors, architects and building owners, roofing performance is about more than appearance. In the article “The Importance of Third-Party Testing and Product Evaluation,” ASC Building Products highlights why independent testing and code compliance play a critical role in the long-term performance of metal roofing systems. 

The article explains that while metal roofing products may appear similar, significant differences can exist in panel design, fastening methods, steel thickness and overall system performance. Third-party testing helps verify manufacturer claims through standardized, accredited processes, giving contractors confidence that products have been evaluated against recognized industry standards and building code requirements. 

Independent testing also helps ensure published performance data is accurate and properly represented. Product evaluation reports go a step further by confirming that tested products comply with applicable building codes and are suitable for their intended applications. This level of verification can simplify product selection and help contractors meet project specifications with greater confidence. 

ASC Building Products maintains two IAPMO-UES Evaluation Reports covering its standing seam and exposed-fastener metal roofing systems. These reports document compliance with multiple editions of the International Building Code and California Residential Code. The evaluations are based on testing conducted in ISO/IEC 17025-compliant laboratories and reference recognized industry standards from organizations including ASTM International and the American Iron and Steel Institute. 

Evaluation reports provide detailed installation requirements, including fastener specifications, clip types and attachment spacing, according to the article. This information can help contractors streamline inspections, reduce the risk of rework and ensure projects meet performance requirements in regions with demanding wind or seismic conditions. 

Beyond structural performance, third-party testing extends to roofing coatings and energy efficiency. Organizations such as the Cool Roof Rating Council evaluate solar reflectance and thermal emittance, helping verify a roof’s ability to contribute to energy savings and comply with programs such as California Title 24 and LEED. 

As metal roofing continues to gain popularity for its durability and longevity, third-party testing remains an important tool for validating performance and supporting successful project outcomes.
