Expert Verdict — Reviewed by the SuperArbor Pro Desk
Place roof drains per the roofing drainage plan and verify the 1-1/2 in. outlet matches the plumbing tie-in before ordering. Install the drain set in conjunction with the Gemini membrane details so flashing at the drain is continuous and watertight. For larger roofs, confirm drain quantity and placement with the design professional.
Follow fall-protection requirements when working on low-slope commercial roofs and verify local plumbing and roofing codes before installing drains.
Order the Atlas Gemini Drain Set for your next commercial roof drainage installation.
