Commercial Panelized Roof Structural Repairs
We specialize in the restoration of panelized roof systems, addressing common issues in commercial flat or low-slope roofs caused by age, overloading, or environmental stress.
- Complete removal and replacement of damaged purlins and sub-purlins to return the roof structure to its original strength and load-bearing capacity.
- Expert fractured or cracked beam replacement, performed safely from above or below the roof deck depending on access and structural requirements.
- Thorough inspection and reinforcement of supporting members to prevent future failures and ensure long-term durability.
Our approach prioritizes structural integrity while maintaining weather-tight protection throughout the repair process.
