Dana Logsdon Roofing San Diego in downtown San Diego's Gaslamp Quarter holds CSLB license #699151 and Owens Corning Platinum Preferred Contractor status—a certification limited to the top half-percent of roofers nationwide—with a downtown office at 770 First Avenue. The company's residential division handles full shingle and tile tear-offs alongside solar-panel installation, pairing rooftop photovoltaic arrays with the structural mounting and electrical tie-ins that Semper Solaris also handles in the Gaslamp corridor. Drone-based inspections photograph the entire roof plane at high resolution before any crew climbs a ladder, mapping crack patterns, ponding zones, and flashing failures into a digital report that anchors the scope of work. Commercial projects use single-ply TPO, PVC, and modified-bitumen systems—including Duro-Last prefabricated membranes—selected by substrate condition, drainage slope, and the building's Title 24 cool-roof compliance requirements. Re-roof scopes often expose fascia and soffit damage that requires repainting once new drip-edge flashing is installed, a finish step coordinated with Precision Painting Plus of San Diego. The most complex projects combine a full commercial membrane replacement, gutter-system overhaul, skylight installation, and attic insulation upgrade into a single weatherproofing scope backed by more than 30,000 completed roofs over 35 years of continuous operation.
