80% of roofs are replaced prematurely each year, millions of square feet of contaminated roofing products go into landfills unnecessarily.

By deferring roof replacement and extending its serviceable life via the Fortis Process, a whole cycle of roof replacement can be removed from landfills and save you significant costs.


Fortis assesses membrane condition, flashing condition, leak history, drainage condition, roof age, maintenance status, insulation condition, rooftop traffic, and interior occupancy.

Fortis utilizes nationally recognized independent labs to test for the top six failure characteristics of commercial low-slope roof systems, measured against more than 15 years of control samples:

  • Elasticity
  • Elongation
  • Tensile/Tear Strength
  • UV Resistance/Heat Aging
  • Water Vapor Permeability
  • Factory Seam Strength

An electronic report is prepared and presented. Key components of the RCIR include:

  • Summary of Roof Data
  • Identification of Defects
  • Science and Technology Results
  • Reconditioning Scope
  • Conventional Roof Replacement Comparison
  • Proposal with ROI Model
