Protect the space
Power off wet areas
If water is near outlets, lighting, panels or equipment, have a qualified person shut off power to that area.
Contain the water
Use buckets, plastic sheeting and wet vacs. Note every leak location and the time, for the roofer and for insurance.
Keep staff off the roof
Roof edges, skylights and wet membranes are serious fall hazards. Leave access to trained roofers with fall protection.
Common commercial roof leaks
Leaks at seams and membranes
Open seams and punctures let water travel under the membrane, so the drip inside may be far from the hole.
Rooftop equipment curbs
HVAC units, exhaust fans and pipe penetrations are common leak points where flashing fails.
Clogged drains and ponding
Water that cannot drain finds any weak point and adds heavy load to the roof deck.
Ceiling tiles and plenums
Water can sit above acoustic tiles before it shows. Wet tiles and insulation need replacing. See commercial water damage restoration.
What to have ready when you call
- Property ZIP code and building type
- Where water is coming in and how much
- Whether equipment, inventory or occupied areas are affected
- Roof type and any warranty information
- Roof access and an on-site contact
- Who can authorize work and any vendor requirements, such as a COI
How commercial roof leak repair usually works
- Make it safe inside. The leak area is protected and electrical hazards are addressed.
- Trace the leak. The roofer inspects seams, flashing, drains and penetrations above and around the leak.
- Temporary repair. If weather allows, the roofer may make a temporary seal to stop water until a permanent repair can be done.
- Permanent repair. Failed seams, flashing or membrane sections are repaired or replaced when conditions are right.
- Interior follow-up. Wet ceiling tiles, insulation and finishes are dried or replaced to prevent mold.
Many roofing materials cannot be installed properly in rain or freezing conditions. Temporary measures buy time until the permanent repair can be done safely.

Call 833-877-1717Commercial roof leak questions
Can a roofer repair a leak during rain?
Sometimes a temporary seal or cover can go on in light rain, if it is safe. Permanent repairs usually need dry conditions.
Why is the drip far from where the roof is damaged?
Water travels along the deck, insulation and framing before it finds a way down, so the entry point can be some distance away.
Do wet ceiling tiles need to be replaced?
Usually. Stained or sagging acoustic tiles hold water and can grow mold. Replace them after the leak is fixed.
Does RepairNowUSA guarantee response times?
No. RepairNowUSA connects you with a participating independent provider when one is available. Timing depends on your area, weather and provider capacity.
Can I call at night or on a weekend?
Yes. You can call 833-877-1717 at any time, including nights, weekends and holidays. Whether an independent provider can come out right away depends on your ZIP code, the time and provider capacity, so availability is not guaranteed.
