Commercial Roof Leak Repair: What Do You Do When a Roof Leaks?

Fast triage checklist for facility teams (what to do right now)

A leak doesn’t just threaten a ceiling tile, it threatens inventory, electrical systems, finished spaces, tenant satisfaction, and operations. The goal is to protect the building first, then document the right details so diagnosis is faster.

Step 1: Protect and contain

• Move or cover sensitive equipment and inventory

• Use catch containers and plastic sheeting

• If water is near electrical: isolate the area and follow your safety protocol

Step 2: Document (this saves time and money)

Take photos or video of:

• the interior leak location (wide + close-up)

• ceiling tiles removed (if safe) to show active drip points

• exterior conditions (wind/rain direction, storm timing)

• any visible rooftop damage (if you have safe access)

Also note:

• when it started (time and date)

• whether it happens only during heavy rain, wind-driven rain, snowmelt, etc.

• whether it’s a repeat issue in the same zone

Step 3: Avoid the “quick fix” trap

It’s tempting to smear sealant where it “looks suspicious.” The problem is: if you seal the wrong detail, you can make the true entry point harder to find, or trap water where it shouldn’t be.

If you need a temporary measure, treat it as temporary, and get a real diagnosis scheduled.

When to call (and what to have ready)

If any of the following are true, it’s time to schedule an inspection:

• the leak is active or increasing

• you’ve repaired it before and it came back

• you see ponding, membrane damage, or drainage issues

• the building has critical areas at risk (electrical, inventory, tenant spaces)

To speed things up, have:

• building address and roof access notes

• leak timing and weather conditions

• photos/video of interior and (if safe) roof area

• any roof history you have (previous repairs, warranty info)

• billing name and address

If you want a clear answer, where the leak is coming from, what the fix should be, and what your next best step is, request an inspection. We’ll help you move from “reacting to leaks” to a plan you can count on.
