Velociflex Features & Benefits

A Velociflex roofing system is highlighted by two plies of modified bitumen membranes. The base sheet is “loose-laid” and mechanically attached in the side laps, which allows for fast and efficient installation.

Anatomy of a Velociflex System

  • Highly Reflective ‘Kool Roof’ Options: Velociflex systems using a Polyfresko G cap sheet comply with the 2016 Title 24 Part 6 Cool Roof Requirements and are ENERGY STAR® Certified.
  • Long-Term Performance: As a redundant, multi-ply, modified bitumen roof system reinforced with high strength polyester, Velociflex is great for new roofing, re-roofing, and recovery systems.
  • Tested & Certified: UL Classified for use in Class A roofs, as listed in the latest UL “Roofing Materials and Systems Directory”, and Florida Building Code approved.
  • Watertight System: A Velociflex system acts as a temporary roof once base sheet seams are heat welded.
  • Self Venting System: The “loose-laid” base sheet reduces the chances of blistering from substrate to membrane.
  • Economical: With a base sheet fastened in the seam only, you can reduce material and labor costs.

The System Within The Name- the ability to withstand high wind velocity with extreme flexibility.

The Polyglass Velociflex high wind resistant roof assembly is designed for steel or structural concrete decks. This system is suitable for new, reroof (Tear Off) or recover. The assembly consists of insulation (preliminary attached), mechanically attached base sheet, optional base ply with a bonded roof cover.









Simple to understand, explain, support and believe in! Even better — all of these benefits are now available to our architect, engineer, consultant and contractor base with the quality of our products! Click the image above for an installation video.

The density of the fasteners installed on the side lap of the base ply along with the specific Polyglass product being used shapes the ultimate negative uplift capabilities. Along with the assembly design from the deck up, the cap ply bonding method is used to shape and determine the negative uplift capabilities. All methods of attaching the cap ply (APP & SBS) are available depending on the negative uplift desired. Torch, Asphalt, Cold Applied, and Self-Adhered.
