The challenge

B&R Gulf's building has a long-span roof that drains into parapet gutters along the walls. Where the roof sheets meet the parapet, water sits against the joint after every rain, and the fastener rows and end laps across the slopes had started to let water through.

What ETCE did

ETCE lined the parapet gutters with EPDM taken up the wall face and down under the roof sheets, sealed the ridge line with twin EPDM runs, closed the end laps and sealed the fastener heads across the roof. Turbine ventilator bases were flashed, and the gutters were water-tested with hoses to confirm the lining held.

Failure points treated on this roof

Materials & method

  • EPDM membrane (1.2 mm) cut to width for each detail: UV-stable and flexible at Gulf roof temperatures.
  • Promax Bonding Adhesive, rated for surface temperatures up to 120°C, for a permanent bond to the metal sheets.
  • Preparation first: old coatings, failed sealant and loose rust removed so the membrane bonds to sound metal.
  • Roof-side, zone-by-zone execution so the building below keeps operating with no shutdown.
  • Working-at-height HSE: trained crews, full PPE and safety lifelines on every roof.

The result

From gutter to ridge, the roof's water paths are now sealed with one continuous membrane system, photographed and tested at handover.
