Fastener Pull Testing
Point-Level Test of Fastener & Deck Holding Strength for Compliance and Performance
Pull tests measure the attachment strength of roofing fasteners in existing decks and repairs, ensuring your system meets design, code, and warranty requirements.
Fastener Pull Testing to Verify Attachment Performance & Design Verification
Fastener pull testing verifies the strength of your roof deck and ensures that roofing systems can be installed to meet wind-uplift, warranty, and code requirements. By testing fasteners directly on your structure, we provide the data you need to design and approve a roof system that will perform safely and reliably.
When to Perform Fastener Pull Testing:
- Before Re-Roofing: Confirm that existing substrates can hold new systems or identify areas needing reinforcement.
- For Code or Warranty Approval: Meet requirements for building codes.
- On New Construction: Validate that fasteners achieve required resistance in lightweight or unfamiliar decks.
- During Condition Assessments: Reveal weaknesses in aging or deteriorated materials before problems develop.
Benefits of Fastener Pull Testing
- Compliance & Approval – Ensure roofing assemblies meet local codes, manufacturer standards, and warranty conditions.
- Cost Control – Avoid change orders, redesigns, and costly delays by identifying issues in advance.
- Risk Reduction – Prevent failures caused by poor fastening or weakened substrates.
- Clear Documentation – Receive test results and reports that simplify communication with owners, contractors, and manufacturers.
Results & Recommendations
Our testing process identifies the attachment values your roof can achieve and highlights any problem areas. We deliver a detailed report that includes:
- Field Data Tables – test-by-test pullout values recorded and summarized
- Pass/Fail Summary – clear compliance with code or warranty thresholds
- Deck Condition Insights – identify weak or deteriorated substrates
