What helps the roofer
Gather roof details
Note the roof type, approximate age, any manufacturer warranty and the last contractor who worked on it.
Plan roof access
Know where the hatch or ladder is, who has the key and any safety rules for working near equipment and edges.
Keep staff off the roof
Commercial roofs have edges, skylights and equipment hazards. Leave inspection to trained crews.
Common commercial roof repairs
Seam and membrane failures
Single-ply membranes such as TPO and EPDM can open at seams or puncture from foot traffic and debris.
Flashing and edge metal
Parapets, curbs, expansion joints and edge metal loosen or crack, especially after high wind.
Drains and scuppers
Clogged drains cause ponding, which adds weight and speeds up membrane wear. See flat roof repair.
Wet insulation under the membrane
Water trapped below the membrane spreads and stays hidden. Saturated insulation and decking often need section replacement.
What to have ready when you call
- Property ZIP code and building type
- Roof type, age and any warranty information
- Leak or damage locations and when they started
- Recent storms or work on the roof
- Roof access and safety requirements
- Who can authorize work and any vendor requirements, such as a COI
How commercial roof repair usually works
- Inspection. The roofer walks the roof, checks seams, flashing, drains and penetrations, and matches them to leak locations inside.
- Moisture survey if needed. On larger roofs, infrared scans or core cuts can show where insulation under the membrane is wet.
- Temporary protection. Active leaks may get a temporary repair until conditions allow a permanent one.
- Permanent repair. Seams are rewelded or resealed, flashing is replaced, drains are cleared and wet sections are cut out and replaced.
- Documentation. Photos and a written report help with warranties, budgeting and insurance.
Many manufacturer warranties require repairs by an authorized contractor. Check the warranty before work starts so it is not voided.

Call 833-877-1717Commercial roof questions
Repair or replace a commercial roof?
It depends on age, how much of the insulation is wet and how often it leaks. Many roofs can be repaired for years. A roofer can tell you when repairs stop making financial sense.
Will a repair affect our roof warranty?
It can. Many manufacturer warranties require an authorized contractor and specific materials. Share the warranty with the roofer before work begins.
How often should a commercial roof be inspected?
Many roofers recommend inspections at least twice a year and after major storms, so small problems are caught early.
Can repairs be done while the building is open?
Usually. Most roof work happens outside, but noise, odors from some materials and access needs should be planned with the roofer.
What should we do while waiting for the roofer?
Protect inventory and equipment under leaks, power off wet areas from a dry location, keep staff off the roof and log each leak location with the date and weather.
Can I call at night?
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.
