Stabilizing Compromised Roof Support Systems
Roof framing members—such as glulam beams (GLBs), purlins, and sub-purlins—are essential to the structural integrity of a building. Over time, these elements can suffer damage from excessive roof loads, improper installation, or long-term exposure to moisture and other environmental factors. When these members are compromised, timely repairs are necessary to restore strength and prevent further deterioration.
For this project, our repair strategy combined replacement and reinforcement. Damaged purlins and sub-purlins were either replaced or stabilized using supplemental wood or steel members designed to strengthen the existing framing.
To repair the compromised glulam beam, we used high-strength cable tensioning—a preferred method over traditional steel rod systems due to its flexibility, durability, and reduced impact on surrounding materials. In some cases, we also use embedded steel rods or epoxy injection for internal reinforcement, depending on the beam’s condition and the load requirements.
These targeted repairs helped restore the roof’s load-bearing capacity and improve long-term performance, all while keeping building operations running smoothly and avoiding major disruptions.
