Seam and Membrane Defects
Long seams, punctures, and open laps that let water travel under the surface.
Commercial Roof Repair Services in Bronx, NY
On a large flat roof, one leak can cross the whole building. We repair commercial roofs with a plan that fits how you operate.
Commercial Roofing Repair for Businesses
Commercial roof repair fixes failures on large low-slope roofs, where one leak can cross a whole building. A crew on a large roof checks long runs of seam, dozens of penetrations, and drains spread across a wide area, and the fix has to fit how your business operates.
Common Commercial Roof Problems
Commercial Roofing Systems We Repair
Our Commercial Roof Repair Process
A thorough visit plans access and communication as carefully as the repair.
Roof History Review
We review the building's roof history, system type, and any past repairs or warranties.
Moisture Testing
We use infrared scanning or moisture readings to find wet insulation before it spreads further.
Repair Plan
We scope the repair by area: seams, curbs, parapets, and drains each get their own fix.
Repair and Documentation
We complete the work and provide photos and a written summary for your records.
Emergency Commercial Roof Repair
Active leaks into occupied space cannot wait for a scheduled visit. See emergency roof repair for fast response that stops the damage while we plan the permanent fix.
Preventive Commercial Roof Maintenance
Scheduled visits catch seam and drainage problems while they are small. See our roof maintenance program for details on keeping a commercial roof ahead of costly repairs.
Roof Repair vs. Commercial Roof Replacement
Repair Fits When
- Damage is limited to specific areas.
- Moisture testing shows the rest of the roof is dry.
- The membrane elsewhere is still sound.
Replacement Fits When
- Repairs keep growing in number and cost.
- Moisture mapping shows wide-area saturation.
- The membrane is failing broadly, not in spots.
See commercial roof replacement if your roof is reaching that point.

Frequently Asked Questions
What is a moisture survey and why does it matter?
A moisture survey uses infrared scanning or similar methods to find wet insulation before it becomes a bigger, hidden problem. It is especially useful when leaks keep returning or when you are deciding between repair and replacement.
Can you repair our roof without disrupting our business?
In most cases, yes. We plan access, timing, and noise around your operating hours and tenants, and communicate any changes in advance.
How do you find a leak on a large commercial roof?
We review the roof history, test for moisture with infrared scanning or readings, and trace the source along the affected area. Water can travel far from where it enters, so testing is often necessary.
Should we run an ongoing repair program instead of fixing issues as they come up?
It depends on your roof's condition and how much surprise your building can tolerate. A repair program with scheduled visits often costs less over time than reacting to each new leak.
What does commercial roof repair typically cost?
Cost depends on roof size, the extent of damage, and how much hidden moisture is involved. We provide a written estimate after inspecting and testing the roof.
Do you provide documentation for insurance or ownership records?
Yes. We provide photos and a written summary of findings and repairs, useful for your roof file, insurance claims, or board records.
