Project Coordinated by Carlos RodriguezReplacement & IB PVC Upgrade in Daly City
Completed a full sloped-roof tear-off and installed a new GAF Timberline HDZ shingle system with upgraded underlayment and enhanced ridge and attic ventilation. The project also included removal and replacement of a low-slope section with an IB 50-mil PVC roofing system over DensDeck cover board, including vertical surface treatments, scuppers, and reinforced flashing details. All work was completed to qualify for applicable manufacturer warranties and ensure long-term watertight performance.
