Wind and hail can leave a commercial roof with lifted membrane, punctures, cracks, or wet insulation underneath. Our team uses a layered inspection to assess commercial roof damage, starting with a visual walk of the roof and moving into hail checks, seam probing, moisture scans, and core cuts. If you manage a commercial building, here is what a proper inspection should include and how our team handles each step.
Start with a Visual Inspection of the Roof
The first step of any commercial roof inspection is a visual check. Our crew gets up on the roof and walks it with a checklist before any other tools come out. This step catches the most obvious problems first.
Signs of Wind Uplift
We check whether the roofing system shows any uplift. That includes a membrane fluttering in the wind or sections that have blown off completely.
Holes and Storm Debris
Windstorms can send objects tumbling across a roof. We check for holes punctured in the membrane and for any damage left by debris that moved across the surface.
Pro Tip: After a windstorm, check for debris that has tumbled across the roof. Anything that moved across the surface could have punctured the membrane.
How We Assess Commercial Roof Damage from Hail and Seam Failures
Once the visual check is done, we take a deeper dive. This starts with hail damage, especially if a hailstorm has recently passed through.
Punctures and Spiral Cracks
Hail can puncture a roofing membrane or leave spiral cracks on its surface. We inspect the roof for these marks and anything similar the storm left behind.
Probing TPO Seams
On a TPO roofing system, we go a step further and probe the seams. This confirms that every seam is still heat-welded together and bonded correctly.
Key Takeaway: A thorough inspection goes past the obvious. We check for hail punctures, spiral cracks, and properly bonded seams on TPO roofs.

Moisture Testing and Inspection Tools
The deepest part of the inspection is moisture testing. Our goal here is to confirm there are no active leaks and no wet insulation inside the roof system.
Infrared Cameras and Moisture Scanners
Two of the main tools we bring to a commercial roof are an infrared camera and a moisture scanner. Along with our walk-through checklist, these are some of the basic tools of a full, proper inspection.
How Core Cuts Help Us Assess Commercial Roof Damage
Sometimes the clearest answer comes from good old-fashioned cutting. We cut a core from the roof and pull out the multiple layers of insulation all the way down to the decking, then check each one. When we finish, we put everything back together and patch the area correctly.
Pro Tip: A thorough inspection uses more than one method. Visual checks, moisture scans, and core cuts each show a different part of the roof’s condition.

Why Each Step Matters
A complete inspection moves from the obvious to the hidden. Each stage checks for something different:
| Inspection stage | What we check |
| Visual inspection | Uplift, fluttering, blown-off sections, punctures, storm debris |
| Hail and seam check | Punctures, spiral cracks, heat-welded TPO seams |
| Moisture testing | Active leaks, wet insulation, layers of insulation down to the decking |
