Roof Drains

The best roof drains aren't the ones you notice — they're the ones that quietly handle every rainstorm for 30 years without a callback. That means a heavy drain body that won't crack or warp, a strainer dome that catches leaves without choking flow, and a clamping ring that gets a watertight bite on the membrane without overtorquing.

Our roof drain lineup covers flat-roof and low-slope applications in copper and stainless steel. Bottom-outlet drains tie straight into a vertical leader pipe — standard for most new commercial construction. Side-outlet models connect to horizontal runs, which is what you'll usually need on retrofit work where the plumbing routes are already locked in. Scupper drains handle parapet walls. Overflow drains act as the backup plan when the primary can't keep up during a heavy event.

Match your drain to the membrane system. Copper-to-copper if you're running a full copper roof. TPO-clad or PVC-clad stainless for single-ply systems — those clad flanges hot-weld right to the sheet for a continuous seal. Don't mix metals at the waterline; galvanic corrosion will eat through the joint faster than you'd expect.

Pricing runs from about $70 for a basic unit to over $900 for a fully engineered system with integral overflow. Every piece is made in the USA, and our team can walk you through sizing and configuration if you need a hand.
