Here’s an overview of how the commercial roofing installation process usually plays out:

  • Roof Inspection and Assessment

    Before installation begins, a thorough inspection of the existing roof is conducted to assess its condition. Any necessary repairs or modifications are identified and addressed.

    Design and Planning

    A detailed roofing design is created, taking into account the building’s size, structure, and the intended use of the roof. This design includes the choice of roofing materials and system.

    Permits and Regulations

    Necessary permits are obtained, and the project is planned in compliance with local building codes and regulations.

    Tear-Off (if required)

    If the existing roof is in poor condition, it may need to be removed (i.e. torn off) before the new roof is installed.

    Substrate Preparation

    The roof deck or substrate is prepared to receive the new roofing system. This involves repairing any damaged areas and ensuring a smooth and stable surface.

    Insulation Installation

    Insulation materials are installed to improve energy efficiency and provide thermal protection. 

    Membrane Installation

    The primary roofing membrane (e.g., single-ply, built-up, modified bitumen) is installed in accordance with the manufacturer’s guidelines. Seams are sealed to prevent water infiltration.

    Flashing and Edge Details

    Flashing is added around roof penetrations (vents, pipes, HVAC units) and at the roof’s edges to prevent leaks and enhance the roof’s integrity.

    Roof Accessories

    Roof accessories like roof drains, scuppers, and curbs are installed as needed for proper water drainage and functionality.

    Final Inspections and Quality Checks

    The installation is thoroughly inspected to ensure it meets the design specifications and industry standards.

    Roofing System Protection

    Depending on the roofing type, protective layers such as coatings or ballast may be added to enhance durability and weather resistance.


    The work area is cleaned up, and any debris is removed from the site.
