Steps of Commercial Flat Roof Replacement
Initial Inspection and Planning
Before any work begins, roofing professionals conduct a thorough inspection of the existing roof system. They evaluate the current roofing materials, identify damaged areas, and assess the underlying deck structure. This inspection determines whether a complete tear-off is necessary or if a roof overlay is possible. The team also reviews local building codes and obtains necessary permits for the project.
Preparation and Safety Setup
Safety is paramount in commercial roofing projects. The first physical step involves setting up fall protection systems, including guardrails and warning lines. Contractors also establish designated areas for material storage and debris removal. Protection barriers are installed around HVAC units, skylights, and other rooftop equipment to prevent damage during construction.
Removal of Existing Roofing
The tear-off phase begins with removing the old roofing material down to the deck surface. Workers systematically remove all layers, including membrane, insulation, and flashings. During this process, they carefully protect the building’s interior from weather exposure by working in sections and using temporary covers when necessary. Any wet or deteriorated deck materials are identified and replaced.
Deck Preparation and Repair
Once exposed, the roof deck undergoes thorough inspection and repair. Contractors address any rusted metal, rotted wood, or cracked concrete. They ensure the surface is clean, dry, and structurally sound to provide a solid foundation for the new roofing system. Proper deck preparation is crucial for the long-term performance of the new roof.
Installation of New Roofing System
The installation begins with a base layer of insulation, which is mechanically fastened or adhered to the deck. Additional insulation layers may be added to meet energy code requirements. Next, the chosen roofing membrane (such as TPO, EPDM, or modified bitumen) is installed according to manufacturer specifications. Special attention is given to seam construction and edge details.
Flashing and Detail Work
Proper flashing installation around roof penetrations, parapets, and equipment curbs is critical for preventing leaks. Contractors install new metal flashings, corner pieces, and edge details. They ensure all penetrations are properly sealed and waterproofed, paying special attention to expansion joints and drainage systems.
Final Inspection and Quality Control
Upon completion, the roofing system undergoes rigorous quality control inspection. This includes checking seam integrity, testing drainage patterns, and verifying proper attachment. Many manufacturers require this inspection to validate the warranty. The contractor also ensures all debris is removed and the site is thoroughly cleaned.
