204,000 sq ft1960’sFluid Applied Roofing System: HydroStop and UNISIL by GAF

Installation Highlights

The roof of this property has three different sections and each required different preparation for the new fluid applied system roof installation. For each section, we inspected the sheathing and penetration flashing and performed refastening where needed. We cleaned and prepared the surface with bonding agents and installed the GAF UNISIL Seamless Roofing System in the Energy Star Certified White.

With a 20 year warranty, the building owners have a long-lasting solution with peace of mind.

Roof Section A: Warehouse and Rear Ballasted Roof

  • Removed existing ballast and ballast fabric.
  • Investigated a spongy area and took core samples to determine if a replacement was necessary.
  • Re-secured the section and included full mechanical fastening of the existing EPDM roof.

Roof Section B: Saw Toothed Sloped Roof

  • Replaced the bottom/lower 8 feet to drains.
  • Replaced the bad insulation board and installed a new board with plates and screws.
  • Installed fully adhered 60MIL black EPDM rubber membrane to receive fluid applied system for consistency of look and warranty.

Roof Section C: R&D and 2nd Floor Roof

  • Removed and disposed 27 roof top units on a weekend to minimize disruptions to the parking area.
  • Reinforced all penetrations with fabric and tied the new system into existing edge metal to prevent moisture infiltration on the entire roof perimeter.
  • Cleaned and treated existing drains.
