Roof Drain Installation in the South Bay
New flat roof or an added drain? Request an estimate with the roof plan and leader route.
Schulze Plumbing Inc. provides Roof Drain Installation in the South Bay / Los Angeles County area. See cities we serve or call 310-487-2975.

Roof drain installation is the drain body, flashing ring coordination, overflow if required, and the piping that carries water off the roof. The membrane is the roofer. We work in sequence so the roof is not open longer than it must be.
Commercial low-slope buildings and some modern houses in the South Bay use interior leaders instead of gutters. Those leaders need cleanouts.
Common symptoms
- A roof plan with drain symbols and no plumber
- Ponding with no drain in the low point
- A remodel adding a roof area
What this service involves
- Setting drain bodies to the roof layout
- Running leaders with overflow as specified
- Coordinating with the roofing trade

FAQ
- Do you cut the roof?
- Openings are coordinated. Roofing usually owns the membrane cut and flash. We own the drain and pipe.
- Interior vs scupper?
- Both exist. Interior drains need vertical piping. Scuppers may still need downspout connections.
- Is this storm or sanitary?
- Storm. We do not dump roof water into the sewer as a convenience.
