Drainage & detailing

Drainage and details that decide how long it lasts

Water must leave the roof. Tapered insulation gives it a path to the drains, so ponding never sits on the membrane.

We detail drains and scuppers carefully. Parapet and penetration flashing gets the same care, and every seam is sealed and checked before we move on.

  • Drains & scuppers
  • Parapet flashing
  • Seams checked
