COMMERCIAL DECISIONS
What happens at a commercial roof assessment: free visual review vs. full condition assessment
NanoGuard's free commercial roof assessment is a visual, on-roof review: you get photos and a restore, repair or replace recommendation based on what can be seen. It cannot confirm whether the insulation under the membrane is wet; that is what a paid full condition assessment is for.
What the free assessment covers
A NanoGuard team member walks the roof, photographs what they find and reviews the leaks you already know about. The walk-over looks at:
- The membrane and its seams
- Flashings
- Drainage and any ponding
- Known leak locations
You receive the photos and a restore, repair or replace recommendation based on what is visible. A visual review cannot tell whether insulation is wet.
What a full condition assessment adds
The full condition assessment is a paid service that tests what a walk-over cannot see. It adds:
- Infrared thermography or a moisture survey suited to the roof assembly
- Core samples to verify moisture, insulation condition and the roof build-up, with every core cut sealed watertight
- A section-marked roof plan showing suspect or wet areas and the core results
- A written technical condition report covering each section's condition, remaining service life and the practical path for each section
Testing may be carried out with an independent testing partner, and their findings are attributed in the NanoGuard report.
Free visual review or full condition assessment
| Aspect | Free visual review | Full condition assessment |
|---|---|---|
| What it is | An on-roof walk-over with photos | Moisture testing and core samples, section by section |
| What you get | Photos and a restore, repair or replace recommendation | A marked roof plan and a written condition report |
| Confirms wet insulation | No | Yes |
| Cost | Free | Quoted per building |
| Typical use | A first look at whether restoration is worth pursuing | Larger or complex roofs and decisions with money or a warranty at stake |
When the full assessment is worth it
- Large or multi-section roofs
- Built-up or gravel roofs
- Suspected wet insulation
- Before a capital decision
- Before a warranty-backed restoration

Questions
Is the commercial roof assessment free?
Yes. The visual review is free. The full condition assessment is a paid service, quoted per building.
Can a visual inspection tell if my roof insulation is wet?
No. The insulation sits under the membrane, out of sight. A moisture survey plus core samples confirms whether it is wet.
Do core samples damage the roof?
Each core cut is sealed watertight. Cores are taken only to verify moisture, insulation condition and the roof build-up, and their locations are marked on the roof plan.
