Roof Leaks
Water travels under the membrane before it shows up as a stain, so we trace it to the real entry point.
Flat Roof Repair Services in Bronx, NY
Flat roofs hide problems until water shows up below. We repair seams, punctures, blisters, and drains on every major membrane system.
Professional Flat Roof Repair
A flat roof is a continuous sheet, so one failure can let water travel under the membrane long before a stain appears inside. We find where water is really entering, remove any wet material, and restore the membrane with products that bond to what is already there.

Our Flat Roof Repair Process
A thorough repair follows a set order, from history to confirmation.
History and Interview
We ask about your roof's age, past leaks and repairs, and where water appears inside.
Interior and Surface Check
We check ceilings for stains, then walk the roof surface for seams, blisters, and ponding.
Membrane Identification
We confirm the membrane type, since the repair method and materials depend on it.
Testing
Where the source is unclear, we use moisture readings, infrared scanning, or a controlled water test.
Repair
We prepare the area, remove any wet material, and repair with compatible products.
Flat Roof Repair vs. Replacement
Repair Fits When
- Damage is limited to one or two spots.
- The rest of the membrane is sound and dry.
- Drainage and slope are otherwise working.
Replacement Fits When
- Leaks keep appearing in different places.
- Insulation tests wet beneath the surface.
- The roof is covered in old, failing patches.
See flat roof replacement if your roof is failing broadly rather than in one spot.
How to Prevent Flat Roof Problems
- Clear drains, scuppers, and gutters regularly, especially after leaf fall.
- Address ponding water early, before it ages the membrane.
- Limit foot traffic on the roof, and use walkway pads near equipment.
- Schedule a roof inspection at least once a year.
- Have new patches use materials compatible with your existing membrane.
Frequently Asked Questions
Does a flat roof repair need to match the existing membrane?
Yes. A repair that does not bond to your existing membrane is a temporary cover, not a fix. We confirm the membrane type before choosing repair materials.
Can you repair a flat roof with wet insulation underneath?
We can, but the wet section has to be cut out and replaced with dry material first. Patching over wet insulation is one of the most common reasons flat roof repairs fail.
How long does a flat roof repair take?
Most small repairs are finished in a single day. Repairs involving wet insulation or a larger failed area can take longer.
What causes most flat roof leaks?
Ponding water, seam movement, foot traffic, sun exposure, and clogged drains cause most flat roof problems. Fixing the cause matters as much as fixing the visible damage.
Can I walk on my flat roof to check it myself?
You can look from a safe vantage point like a window or hatch, but we do not recommend walking on a flat roof. Wet membranes are slippery, and low parapets and open edges cause serious falls.
When is flat roof damage an emergency?
Treat it as urgent when water is actively entering your building or the ceiling looks unsafe. Call us and we will respond quickly.
