Visual Inspection Surveys
Visual roof inspections involve a manual, physical examination of the roofing surface by a trained technician to identify visible signs of damage or deterioration.
Use-Cases
- Routine maintenance and condition assessments.
- Pre-sale or pre-purchase property surveys.
- Insurance inspections.
- Initial diagnostics before performing more detailed testing.
- Areas where electronic testing is not possible or too costly.
Limitations
- Not suitable to secure manufacturer guarantees.
- Limited in finding issues before they become serious.
- Cannot map or measure leak paths like electronic methods.
- Some defects may be missed if subtle or hidden.
1|Universal Method
- Can be performed on all roof types where electronic detection is not possible.
2|Cost-Effective
- Requires minimal specialized equipment.
- Discover issues before they become worse.
3|Can Detect Broader Issues
Not limited to membrane punctures; can identify:
- Drainage problems
- Structural movement
- Poor workmanship
- Weathering or aging
4|No Grounding Required
- Unlike dry testing, visual inspections don't depend on a conductive substrate or membrane conductivity.
5|Suitable For All Conditions
- Doesn't require the roof to be dry or wet — just accessible and safe.
