What to Expect During a Professional Roof Inspection
A commercial roof inspection looks at the roof from the outside and, where useful, from inside the building. The inspector checks the roof surface, flashings, drainage, seams and penetrations for signs of deterioration, leaks and water entry risk, and looks for ponding water on flat and low slope roofs. Our commercial roof inspection service follows this approach.
Some roofs call for additional tools to find moisture that cannot be seen. Depending on the roof, an inspector may use moisture meters, infrared imaging or core samples. These methods have limits, which is why the report should say what was used and what it cannot confirm.
Things To Look For
On commercial roofs, important findings often occur at roof details as well as on the open surface:
- Seams: separated, open or poorly bonded seams on membrane roofs
- Flashings: cracked, loose or pulled-away flashing at walls, curbs, vents and penetrations
- Drainage: clogged drains, standing water and debris that hold water on the roof
- Surface condition: blisters, splits, punctures, worn coatings or aging membranes
- Edges and equipment: damaged edge metal and rooftop units or curbs that are not sealed well
- Interior signs: ceiling stains, damp insulation or musty areas that can point to a leak
Water entry can damage interior materials if not addressed. Documenting an apparent defect early gives the owner a chance to evaluate its scope before selecting a repair.
What a Good Inspection Report Contains
A report is more useful when it is organized so that someone who was not on the roof can follow it. This outline shows the sections an owner should expect.
| Report section | What it should contain | Why it matters |
|---|---|---|
| Roof and building details | Address, roof type, approximate area, age if known, date and conditions of the inspection | Gives every later finding a context and a date |
| Dated photos | Photos of each problem area and of overall roof sections, labeled by location | Lets you compare conditions at the next inspection |
| Defect locations | A marked plan or description of where each defect is, such as seams, flashings, penetrations and drains | Lets a crew and an estimator find the same spot |
| Moisture findings and limits | What was checked for moisture, with the method used and what that method cannot confirm | Prevents a surface reading from being treated as proof |
| Prioritized actions | Items grouped as urgent, plan soon or monitor, each tied to a finding | Turns a long list into a sequence of decisions |
| Reinspection triggers | Conditions that call for another look, such as severe storms, a new leak or a set interval | Keeps the report useful after the visit |
When Thermal Findings Need Confirmation
Infrared imaging can show temperature differences that suggest moisture below the surface, but it does not prove that insulation is wet. Conditions at the time of the scan, roof materials and surface debris can all affect what the camera shows. For that reason, thermal findings should be evaluated and confirmed using an appropriate method, such as a suitable moisture survey or core sampling, before they are used to establish the extent of repair or replacement work. Do not treat thermal imaging as a promise of savings or a diagnosis by itself.
Who Receives the Report and How It Becomes an Estimate
The inspection report should reach the building owner or responsible property manager, and be shared with whoever approves the scope and budget. Because it records locations, photos and priorities, it can be used to scope an estimate so that every contractor prices the same defects. From there, the next step may be roof maintenance, commercial roof repair, a coating restoration where the roof qualifies, or roof replacement when the roof system has reached the end of its useful life.
Comprehensive Commercial Roof Inspection Services
Warranty terms depend on the specific roofing work and written agreement; an inspection alone does not establish coverage. Review any existing warranty requirements when deciding what work follows.

Frequently Asked Questions
What should I receive after a commercial roof inspection?
A written report with dated photos, the location of each defect, moisture findings and their limits, prioritized actions and triggers for reinspection.
Does infrared imaging prove a roof is wet?
No. It can suggest where moisture may be, but the findings should be confirmed with another method before a repair or replacement scope is set.
How is the inspection used to get an estimate?
The report lists the defects and their locations, so contractors can price the same work and you can compare bids fairly.
When should a roof be inspected again?
After severe storms, when a new leak appears, or at an interval set in the report based on the roof’s age and condition.
