Emergency Roof Repair: What to Do When Your Commercial Roof Leaks

It’s 2:00 AM during a nor'easter, and you get the call: water is pouring into your warehouse or retail store.

A commercial roof leak is a business owner's nightmare. It threatens inventory, disrupts operations, and creates safety hazards for employees. But panic is your enemy.

At Genc Construction, we handle hundreds of emergency calls every year across New Jersey and New York. We know that the actions you take in the first hour can save you thousands of dollars in damage.

Here is your step-by-step emergency action plan.

Step 1: Safety First (Do NOT Go on the Roof)

This is critical: Never, ever go up on a commercial roof during a storm.

* Wind: Gusts can easily knock you off balance.

* Slipping: Wet membranes (especially TPO and EPDM) are as slippery as ice.

* Lightning: You are the tallest point on the building.

* Collapse: If the roof is sagging or holding heavy water, it could be structurally unsound.

Action: Keep everyone on the ground. The leak is inside; deal with the inside first.

Step 2: Contain the Water Inside

Your goal is to minimize damage to the building's interior and contents.

Clear the Area: Move computers, electronics, and inventory away from the leak zone immediately.

Catch the Water: Place large trash cans, buckets, or tilt trucks under the drip.

Relieve Pressure (If Safe): If water is bulging in a ceiling tile, poke a small hole in the center with a screwdriver to let the water drain into your bucket. This prevents the entire ceiling grid from collapsing under the weight.

Cover Up: Use heavy-duty plastic tarps to cover anything you can't move.

Step 3: Mark the Spot

Leaks can travel. Water might enter the roof at one point, run along a steel beam for 20 feet, and drip down somewhere else.

Action: While it's actively leaking, take photos and mark the floor location with tape. This helps our roofing crew trace the path of the water back to the source once they arrive.

Step 4: Call a Professional Roofer Immediately

Don't wait for the rain to stop. Call a commercial roofing contractor who offers 24/7 Emergency Service.

What to tell them:

* Building Type: (e.g., "Flat roof warehouse in Newark")

* Leak Severity: (e.g., "Steady stream" or "Slow drip")

* Access: (e.g., "We have a roof hatch" or "You need a ladder")

* Height: (e.g., "2-story building")

Step 5: Document for Insurance

While waiting for the crew, start documenting.

* Take photos of the water intrusion.

* Take photos of any damaged inventory or equipment.

* Keep track of the time the leak started.

This evidence is crucial for filing a successful insurance claim later.

What Happens When We Arrive?

When Genc Construction arrives at an emergency call, our priority is Stopping the Water.

Assessment: We safely access the roof to locate the defect (puncture, open seam, clogged drain, or blown-off flashing).

Temporary Repair: We use specialized wet-surface sealants, tarps, or temporary patches that adhere even in pouring rain. This stops the active leak immediately.

Permanent Solution: Once the storm passes and the roof dries, we return to perform a permanent, warranty-backed repair (e.g., heat-welding a new TPO patch or replacing damaged insulation).

Common Causes of Emergency Leaks in NJ/NY

Why did this happen? In our area, it's usually:

* Clogged Drains: Leaves and debris block scuppers, causing water to pond and rise above the flashing height.

* Wind Uplift: High winds peel back edge metal or membrane at the corners.

* Punctures: HVAC technicians dropping tools or wind-blown debris (tree limbs) piercing the membrane.

* Open Seams: Old glue on EPDM roofs finally giving way under freeze-thaw stress.
