Custom Roof Scuppers in Bakersfield, CA
K9 Custom Roofing fabricates and installs custom roof scuppers and drainage details for buildings across Bakersfield and Kern County. Standing water is the fastest way to ruin a flat roof, and off the shelf parts rarely fit an existing parapet or wall detail. We measure, fabricate and flash each scupper on site so water leaves the roof cleanly instead of backing up against the edge.

We also correct undersized or clogged existing drainage that is causing ponding and overflow damage.
What is included in custom scupper work
A K9 Custom Roofing scupper project includes measuring the roof area and drainage load, fabricating the scupper and collector box from sheet metal to fit your exact parapet detail, cutting and framing the opening, then flashing and sealing the assembly into the roof membrane. We finish the exterior metal to match the building. The result drains the roof at the rate it actually needs rather than the rate a stock part happens to provide.
Signs your roof drainage is undersized or failing
Roof drainage is failing when water stays on the roof more than 48 hours after rain, spills over the parapet edge instead of exiting through the scupper, or leaves staining down the exterior wall. Rust at the scupper throat, separated collector boxes and interior leaks near the parapet are the other common indicators. Ponding water is heavy and it accelerates membrane failure everywhere it sits.
What custom scupper work costs in Bakersfield
Scupper pricing depends on how many openings the roof needs, the size and gauge of metal being fabricated, whether the parapet has to be cut and reframed, and how much surrounding membrane must be opened and rebuilt to flash the assembly properly. Adding an overflow scupper next to an existing opening is a modest job. Reworking the drainage on a whole commercial parapet is a larger one. We price the fabrication and the roof work together so there is no gap between trades.
Metals we fabricate with
We fabricate scuppers, collector boxes and coping from the metals that hold up in Kern County heat and rain. The choice comes down to appearance, corrosion exposure and budget.
| Metal | Best for | Notes |
|---|---|---|
| Galvanized steel | Standard commercial drainage | Cost effective and paintable |
| Kynar coated steel | Color matched building details | Long lasting factory finish |
| Aluminum | Coastal or high corrosion exposure | Light and rust resistant |
| Copper | Architectural and historic details | Premium appearance, patinas over time |
| Stainless steel | Heavy duty and long service life | Highest durability, highest cost |
How the scupper process works
Scupper work runs in four steps: we assess the drainage problem, take field measurements, fabricate the metal to those measurements, then install and flash it into the roof. Because the metal is made to your building rather than pulled off a shelf, the fit is tight and the flashing detail is clean.
- 1Drainage assessment
We look at where water ponds, where it overflows and how much roof area drains to each point.
- 2Field measurement
Exact parapet, wall and membrane dimensions are taken so the metal fits the opening as built.
- 3Fabrication
The scupper, collector box and any coping are fabricated in the specified metal and finish.
- 4Install and flash
The opening is prepared, the assembly is set, then flashed and sealed into the roof system and tested.

Custom Scuppers questions
How do I know my roof drainage is undersized?+
Water standing more than 48 hours after rain, overflow at the parapet during storms, or staining running down exterior walls are all signs the openings cannot move water fast enough for the roof area they serve.
Can you match the existing metal on my building?+
Yes. We fabricate to match the color, gauge and profile of existing building details wherever possible, and can work in galvanized, Kynar coated steel, aluminum, copper or stainless.
Is scupper work only for commercial buildings?+
No. Any flat or low slope roof with parapet walls can need scupper work, including residential additions, patio covers and modern flat roofed homes.
Do you also fix the roof around the scupper?+
Yes. Fabrication and the roofing work are done by the same company, so the metal is flashed and sealed into the membrane correctly rather than handed off between trades.
