We completed a series of maintenance and repair tasks on a commercial flat roof in Plano, Texas. Our work included sealing TPO membrane seams, applying targeted patches to worn areas, and addressing flashing transitions along the parapet walls. We also installed a yellow safety guardrail system around the main roof hatch to meet safety requirements and protect personnel during future rooftop maintenance. To ensure long-term durability, we secured existing conduit with new rooftop support blocks and inspected the internal drainage system for obstructions. We focused on reinforcing high-traffic areas and penetrations with industrial-grade sealants to prevent moisture intrusion. These improvements resolved recurring drainage concerns and extended the service life of the building's low-slope roofing system.
