Clogged Drains
Leaves, grit, and debris block flow and hold moisture against the roof.
Roof Drain Repair Services in Bronx, NY
When roof drains fail, water stays on the roof and finds a way in. We repair drains, scuppers, and leaders and test the flow, not just clear the blockage.
Professional Roof Drain Repair
A flat roof depends on its drains more than any other part. If they clog, crack, or leak, water stays on the roof, wears the membrane, and finds its way into the building. Repair ranges from clearing a strainer to replacing a drain bowl and re-flashing the membrane around it.
Common Roof Drain Problems
Why Proper Roof Drainage Matters
Standing water ages a roof membrane faster than almost anything else, stresses seams, and adds weight to the structure. Working drains are one of the most important parts of any flat roof, and they are often the easiest problem to prevent with regular checks.
Signs Your Roof Drain Needs Repair
- Water lingering around a drain after rain. A working drain leaves the area dry soon after rain stops.
- Overflow from a scupper or gutter during heavy rain. The primary route is not keeping up.
- Stains on the ceiling or wall near a leader pipe. A leaking joint may be sending water into the building.
- A gurgling sound or slow drainage. Air and partial blockages make noise as water struggles to leave.
- Ice or icicles at scuppers in winter. Frozen water can block the path and back up onto the roof.
Our Roof Drain Repair Process
We test flow as well as clear the drain.
Locate Every Drain
We find every drain, scupper, and overflow on the roof and mark each one.
Clear and Inspect
We clear debris and inspect the membrane, clamping ring, and drain bowl for damage.
Test Flow
We run water into each drain and watch how quickly and cleanly it leaves.
Repair Hardware
We repair or replace strainers, seal or re-flash the membrane, and fix damaged hardware.
Retest and Document
We retest drainage and give you a written summary with maintenance advice.
Roof Drain Maintenance
Regular clearing, especially after leaf fall, prevents most drain emergencies. See our roof maintenance program for a routine that keeps drains flowing year-round.
Roof Drain Repair for Commercial and Flat Roofs
Larger flat roofs often have multiple drains, scuppers, and overflow paths that all need to work together. We inspect and repair drainage systems on apartment buildings, shops, and commercial properties, coordinating with commercial roof repair where broader work is needed.
Frequently Asked Questions
How often should roof drains be cleaned?
Often enough that they never stay blocked. That usually means after leaf fall, before winter, and after major storms, and more often under heavy trees.
What is an overflow drain, and does my roof need one?
An overflow drain or scupper sits slightly above the main drain so water can still leave if the primary drain clogs. Many codes require them on flat roofs, and we can confirm whether yours has one and whether it works.
Can I clear my own roof drains?
We do not recommend it. Debris hides holes and soft spots, wet membranes are slippery, and parapets are often low. Leave drain clearing to professionals with proper fall protection.
Why do my roof drains freeze in winter?
Water in exposed drains and leaders can freeze when temperatures drop, and ice can block the path or crack the pipe. Leaders in unheated spaces are more at risk.
Do drain covers or strainers really help?
Yes. They keep leaves and debris out of the pipe, which prevents deeper blockages, though they still need regular cleaning themselves.
What does roof drain repair cost?
Simple clearing costs far less than replacing damaged hardware. We will tell you which your roof needs before we start any work.
