Project Overview

The Grand Gulf Nuclear Power Plant, operated by Entergy, required a secure, high-performance roof replacement at one of the most regulated facilities in the Southeast. Independent Roofing was selected for its clearance-ready crews, safety protocols, and expertise with precision commercial systems under federal oversight.

Project Details

Challenge / Objective

The roof system had reached the end of its service life, showing membrane failure and degradation due to UV exposure and age. Being a nuclear facility, the project required:

  • Security-cleared crews and materials staging
  • Strict adherence to documentation and inspection standards
  • Coordination with facility management to avoid operational disruption
  • Daily activity reporting and compliance logging

Notable Features

  • Cleared, federally compliant crew
  • In-house metal fabrication for detail accuracy
  • Full membrane weld inspection and warranty registration
  • Zero disruption to plant operations

Solution

Independent Roofing worked with Entergy to scope, plan, and phase the work in a controlled environment:

  • Removed deteriorated roofing assemblies and repaired substructure as needed
  • Installed a mechanically attached single-ply membrane system with high tensile strength and wind uplift resistance
  • Fabricated all edge metals and terminations in-house for precision and compliance
  • Managed a cleared crew with controlled access, escorted entry, and full safety documentation

System Specs

  • Roof Type: Mechanically Attached Single-Ply Membrane
  • Membrane Features: UV-resistant, reinforced membrane with high puncture and uplift resistance
