Structural Repair Portfolio GLB, Purlin and Sub-Purlin Repairs

Stabilizing Compromised Roof Support Systems

Structural framing members—such as glulam beams (GLBs), purlins, and sub-purlins—can suffer damage over time due to excessive roof loads, improper installation, or prolonged exposure to moisture and other environmental conditions. When these critical elements are compromised, timely repair is essential to restore load-bearing capacity and prevent further structural deterioration.

On this project, our repair approach included a combination of member replacement and reinforcement. Damaged purlins and sub-purlins were either replaced or stabilized using additional wood or steel supports to strengthen the framing system.

For the glulam beam repair, we utilized high-strength cable tensioning to reinforce the damaged section—our preferred method over traditional steel rod tensioning due to its flexibility, durability, and lower installation impact. In certain cases, we also employ epoxy injection or embedded steel rods when internal reinforcement is required.

These repairs helped restore the structural performance of the roof framing while minimizing disruption to the building’s operation.
