Tenant improvements often require modifications to your commercial flat roof—whether it’s adding new rooftop equipment, making structural changes, or enhancing energy efficiency. At Saddleback Roofing, we provide specialized roofing services to support tenant improvement (TI) projects on buildings with TPO or (PVC), built-up roofing (BUR) or Roof Maintenance Coating systems. 

Our team works closely with property managers, general contractors, and tenants to ensure that all roofing modifications are completed safely, efficiently, and in full compliance with building codes and manufacturer specifications. 

Our roofing TI services include: 

• Roof penetrations for HVAC, vents, and electrical systems 
• Flashing installation and waterproofing around new equipment 
• Reinforcement and curb installation on BUR and TPO roofs 
• Coordination with other trades to protect existing roofing 
• Repairs and sealing to maintain the roof warranty 
• Roof upgrades to meet code or energy efficiency standards 
• Ensuring that the alterations are in compliance with existing manufacturer’s warranty requirements

Whether you’re upgrading a retail space, office, warehouse, or industrial unit, we ensure the roof remains watertight and fully functional throughout the improvement process. We specialize in maintaining the performance and integrity of single-ply, BUR or Roof Maintenance Coating Systems systems during construction and remodeling.
