A drone roof inspection uses an unmanned aircraft flown by a certificated remote pilot to capture overview and close-up imagery of a commercial roof: the membrane or surface, seams, drains, scuppers, flashings, penetrations, rooftop units and parapets. Northmark flies drone roof inspections for commercial buildings in Fargo, West Fargo and Moorhead and delivers organized, dated images with a summary of visible observations, so owners and managers can see their roof's condition without sending anyone up.
Why inspect a commercial roof by drone
Commercial roofs are expensive, out of sight and easy to neglect. Problems usually show up as a ceiling stain inside, by which point water may have been getting into insulation for months. Regular inspection is the answer, but traditional roof walks come with cost and risk.
Falls are one of the leading causes of serious work-related injuries, and OSHA's fall protection resources reflect how seriously roof work must be managed. A drone reduces how often people need to be on the roof at all. It also sees the whole roof at once, which is hard to do from the surface.
| Factor | Drone roof inspection | Traditional roof walk |
|---|---|---|
| Fall exposure | Pilot stays on the ground | Inspector on the roof |
| Coverage | Entire roof plus overview context | Limited by time and access |
| Speed | Typically one short visit | Can take longer on large roofs |
| Documentation | Consistent, dated, repeatable imagery | Depends on the inspector's photos |
| Hands-on testing | No (visual only) | Yes: probing, moisture meters, core samples |
The right choice is often both. A drone documents the whole roof quickly and repeatedly, and a roofer goes up when the imagery shows something that needs hands-on assessment. See drone vs manual roof inspection.
What we capture
- Overview images of the full roof, so you can see layout, equipment and drainage paths
- Section images at consistent angles, so later inspections can be compared directly
- Detail images of drains, scuppers, seams, flashings, penetrations, curbs and parapet caps
- Rooftop equipment: visible condition of units, panels, curbs and supports
- Ponding and debris: standing water, blocked drains, debris accumulation
- Visible damage: punctures, displaced material, blistering, open seams, missing flashing, impact marks
You receive the imagery organized by roof section, labeled with the date, plus a short written summary of visible observations.
Fargo–Moorhead roofs face specific stresses
Red River Valley weather is hard on commercial roofs:
- Snow load and ice dams stress structures and drainage through long winters.
- Freeze-thaw cycles in spring and fall work moisture into seams and flashings.
- Spring melt tests drains and scuppers that may be blocked by debris left over from fall.
- Summer severe weather, including hail and high winds, is a regular feature of National Weather Service warnings for the region.
That makes timing important. Many owners schedule a spring flight after snow melt, to find winter damage and blocked drains, and a fall flight before snow, to clear debris and confirm drainage. Hail season adds another reason to keep a recent baseline. See hail season roof documentation.
How a drone roof inspection works
- Scoping: we confirm the building, the roof areas involved, your purpose (maintenance, sale, lease, warranty or insurance) and your deadline.
- Airspace and safety check: we review controlled airspace, obstacles and nearby people, and obtain FAA authorization where required.
- Flight: our Part 107 remote pilot flies the mission, usually in a single visit for a typical commercial roof.
- Organization: images are sorted by section and labeled with date and location.
- Delivery: you receive the imagery and a summary of visible observations.
What we do not do
We document visible conditions. We do not cut cores, probe membranes, run moisture surveys, certify roof condition or recommend specific repairs. Those are jobs for a roofing contractor or engineer, who can use our imagery to plan their work. Keeping that line clear protects you from vendors who over-diagnose from photos.
Building a roof history
A single inspection tells you how the roof looks today. A series tells you how it is changing. We recommend documenting roofs on a regular cycle, often spring and fall, and storing the imagery with your property condition reports. Over time that record supports maintenance budgets, warranty discussions, sale due diligence and insurance claims.

Frequently asked questions
Can a drone replace a roofer's inspection?
Not entirely. A drone documents visible conditions across the whole roof quickly and safely. A roofer is still needed for hands-on testing, diagnosis and repairs.
How often should a commercial roof be inspected?
Many owners inspect twice a year, in spring and fall, plus after major storms. Drone documentation makes that schedule practical.
Do you need access to our roof?
Usually not. The pilot flies from the ground. We may need access to the site and permission from building management.
What do we receive after the flight?
Organized, dated roof imagery by section and a written summary of visible observations.
