Engineered Flat & Low-Slope Roof Drainage & Sealing

Comprehensive Engineering Overview

Flat and low-slope roofs present unique engineering challenges because water does not shed via gravity at the rapid pace of steep-slope roofs. Any slight imperfection in slope, scupper sizing, or seam welding can create standing ponding basins that accelerate membrane degradation and stress roof joists.

Our flat roofing specialists employ positive-drainage designs utilizing tapered insulation slopes, industrial pitch pockets, and robotic hot-air seam welders to form monolithic, watertight seals capable of withstanding prolonged hydrostatic head pressure.

Key Protocols & Workmanship Standards:

  • Tapered polyisocyanurate insulation crickets directing water toward scuppers
  • Hot-air welded TPO and PVC seams stronger than the membrane itself
  • Thick multi-ply APP and SBS torch-down and cold-applied modified bitumen
  • Internal conductor drain bowl replacements and clamping ring installations
  • Parapet wall coping metal caps and masonry counter-flashing reglets
