Damaged Shingles
Cracked, curled, or missing shingles expose the layers beneath to water.
Roof Leak Repair Services in Bronx, NY
A leak is a symptom, not the problem. We trace the water to its real source and repair the cause, so the fix actually lasts.
Professional Roof Leak Detection and Repair
A leak repair is different from a patch. A patch covers what you can see. A repair follows the water to its real entry point, often several feet from the stain, and fixes both the opening and the reason it opened.
If water is actively entering your building right now, see emergency roof repair instead.
Common Causes of Roof Leaks
Signs of a Roof Leak
- A stain that keeps returning. The source is still open, whatever was done to the ceiling.
- Leaks only in wind-driven rain. Water pushed sideways finds gaps ordinary rain misses.
- More than one stain. This may mean one long path, or several separate entry points.
- Damp or musty insulation. Wet insulation holds moisture against the deck even after the leak stops.
- A flat roof with nearby puddles. Ponding and leaks together suggest a failed seam or drain.
How We Find the Source of a Roof Leak
We trace the likely path uphill from the stain, checking the roof surface, flashing, penetrations, and drains along it. Where the source is not obvious, we use moisture readings, infrared scanning, or a controlled water test to confirm it before we repair anything.
Our Roof Leak Repair Process
Trace the Leak
We follow the water back to its actual entry point, not just the stain.
Confirm the Cause
We use testing where needed to confirm the source before repairing anything.
Repair the Source
We fix the entry point and the reason it failed, including any wet material underneath.
Test and Confirm
We test the repair and tell you what to watch for during the next rainstorms.
Why Roof Leaks Should Not Be Ignored
Water keeps spreading through insulation and framing even when you cannot see it. A slow leak left alone softens decking, rusts fasteners, and can turn a simple patch into a much larger repair.
Roof Leak Repair for Residential Properties
We repair leaks on houses, row homes, and multi-unit buildings, tracing water through attics, ceilings, and walls to the true source.
Roof Leak Repair for Commercial Properties
On larger flat roofs, one leak can travel across an entire building. We trace and repair commercial leaks with minimal disruption to tenants and operations.
Frequently Asked Questions
Will a repair match the rest of my roof?
Usually close, but not always exact. Shingles fade with age and some products are no longer made, so a repaired section can look slightly different. Flat roof patches are typically less noticeable.
Why do roof leaks come back after a repair?
Most repairs that fail were fixing the symptom, not the source, used the wrong material, or missed a second entry point. We trace the full path before we repair, to avoid all three.
How do I know the repair actually fixed the leak?
We test the repair area before we leave and tell you what to watch for during the next few rainstorms. If a stain reappears, call us and we will come back to it.
Is a sealant fix enough, or does the flashing need rebuilding?
It depends on how far the material has worn. Sealant works on small, sound gaps. Worn or lifted flashing needs to be rebuilt, not resealed. We will tell you honestly which your roof needs.
What does it cost to find and fix a roof leak?
Cost depends on the source and how much hidden damage is involved. Straightforward leaks cost less than ones requiring extensive tracing or wet material replacement.
When is a roof leak an emergency?
A leak is an emergency when water is actively entering your building, or when structural or electrical safety is at risk. Otherwise, we can schedule a repair visit.
