A commercial roof inspection in Lansing, MI should leave the owner with more than a verbal opinion. The useful outcome is documented evidence that shows what was observed, where concerns are located, what remains uncertain, and which findings call for maintenance, repair, further investigation, or longer-term planning.
Armor Commercial Roofing provides commercial roof inspection services in Lansing. Its current inspection guidance includes checks of drainage, seams, penetrations, flashing, movement, and signs of water infiltration, followed by a detailed condition report and recommendations when repairs are indicated.
Commercial Flat vs Sloped Roof Inspection
The inspection emphasis changes with roof design. Flat and low-slope commercial roofs rely heavily on drainage and membrane continuity, so inspectors pay close attention to drains, scuppers, ponding areas, seams, penetrations, flashing, previous repairs, and the condition of the membrane field.
Sloped commercial roofs move water differently, so inspection attention shifts toward transitions and termination points such as ridges, valleys, eaves, penetrations, flashing, panel seams, and fasteners where those details are part of the system. The goal is the same in either case: connect visible conditions to specific locations and determine whether the issue appears isolated or needs broader investigation.
Focus of a Flat or Low-Slope Roof Inspection
Drainage deserves close review because standing water, blocked drains, or recurring wet areas can signal a condition that needs maintenance or repair. The inspection should also check seams, membrane surfaces, flashing, penetrations, and earlier repairs for deterioration or movement.
If a low-slope roof uses a single-ply membrane, the inspector should evaluate the details that matter to that assembly rather than apply a generic checklist. Armor’s single-ply roofing information provides additional context for membrane systems and their details.
How a Sloped Roof Inspection Differs
A sloped roof inspection still reviews flashing, penetrations, drainage paths, and material condition, but the priority areas are often different. Valleys, ridges, edges, transitions, and roof-mounted equipment can interrupt the normal water path and deserve careful review. On metal systems, panel seams and fasteners may also be part of the inspection when applicable.
The inspection should document what was actually found rather than assume that one roof type always fails in the same way. That makes the final report more useful when the owner compares maintenance, repair, or replacement options.
What a Useful Inspection Report Should Include
Armor’s current service page says owners receive a detailed report after the inspection. A practical report can be reviewed against the outline below so the next decision stays tied to evidence.
| Report item | What it should show | Why it matters |
|---|---|---|
| Dated photos | Visible roof conditions and important details tied to the inspection date | Creates a baseline that can be compared with later inspections or completed repairs |
| Defect locations | Where seams, flashing, penetrations, drainage concerns, or other defects were observed | Connects a proposed repair to a defined roof area instead of a vague description |
| Moisture findings and limits | What screening or testing was performed, what it suggests, and what still needs confirmation | Prevents a suspected moisture area from being treated as a proven repair boundary without enough evidence |
| Prioritized actions | Which findings need prompt attention, which can be scheduled, and which should be monitored | Helps separate immediate repair work from routine maintenance and capital planning |
| Reinspection triggers | Conditions such as a new leak, significant storm, visible change, or planned review date | Gives the building team a clear reason to inspect sooner than the normal schedule |
When Thermal Findings Need Confirmation
If infrared or other thermal screening is used, the result should be treated as evidence that may justify closer investigation, not as proof by itself that a specific area contains wet insulation or damaged roofing. Surface conditions and roof construction can affect thermal patterns.
When a suspected moisture area would change the repair or replacement scope, the report should state what has been confirmed and what still needs additional testing. That distinction keeps an estimate from presenting an uncertain condition as a settled fact.
How the Report Becomes a Scoped Estimate
The completed report typically goes to the property owner, facility manager, or person responsible for the roofing budget. From there, repair or maintenance proposals can reference the documented locations, priorities, and remaining unknowns.
A useful estimate should explain which report findings it addresses, what work is included, and what conditions could require additional investigation or an approved change. If the inspection shows broader deterioration, the same report can help the owner compare repair with restoration or replacement instead of making that decision from a single symptom.
Get the Right Roof Inspection for Your Building
Armor Commercial Roofing’s current inspection guidance recommends regular inspections and specifically suggests spring and fall reviews, with additional inspections after significant storms. The appropriate schedule for a particular building can also depend on roof condition, repair history, rooftop activity, and any applicable warranty requirements.

Frequently Asked Questions
How often should a commercial roof be inspected?
Armor’s current guidance suggests spring and fall inspections, plus additional review after significant storms. The actual schedule can also depend on roof condition, repair history, rooftop activity, and applicable warranty requirements.
Can thermal imaging alone confirm moisture beneath a roof?
No. Thermal screening can identify areas that may deserve closer investigation, but findings that affect repair scope should be confirmed with appropriate follow-up evidence.
What should a commercial roof inspection report include?
A useful report should document observed conditions, locations, photos when provided, moisture-test limitations, prioritized actions, and clear triggers for future inspection.
How does an inspection report help with a repair estimate?
It gives the owner documented findings that can be matched directly to the proposed work, exclusions, priorities, and any additional investigation listed in the estimate.
