What Factors Influence Commercial Roof Inspection Costs?
Not all roofs (or inspections) are created equal. Here are the biggest cost-driving factors:
✅ 1. Roof Size
Commercial roofs span anywhere from 2,000 sq. ft. to over 100,000 sq. ft. Larger roofs take more time and equipment to inspect. Expect to pay:
| Roof Size (sq. ft.) | Average Cost |
|---|---|
| 0–5,000 | $250–$450 |
| 5,000–20,000 | $450–$850 |
| 20,000+ | $850–$1,500+ |
✅ 2. Roof Type & Material
- Flat roofs (common in commercial properties) are easier to inspect than sloped roofs.
- EPDM, TPO, and modified bitumen require specialized knowledge.
- Metal and thermoplastic roofs may need infrared or moisture scan technology.
Infrared thermal scans can add $300–$1,200 depending on the size and complexity.
✅ 3. Inspection Type
Basic visual inspections are the most affordable, but advanced techniques come at a premium.
| Type of Inspection | Cost Range | Description |
|---|---|---|
| Visual | $200–$500 | Manual inspection of surface conditions. |
| Drone Inspection | $300–$800 | High-res aerial images without risking safety. |
| Infrared Scan | $500–$1,200 | Thermal imaging to detect moisture under the surface. |
| Core Sampling | $100–$300/sample | Analyzes roof layers for damage, often needed for insurance or replacement estimates. |
✅ 4. Accessibility & Safety Requirements
If your building is over three stories or lacks safe access, costs increase due to equipment and labor requirements.
Why Are Roof Inspections Essential for Commercial Buildings?
According to the National Roofing Contractors Association (NRCA), commercial roofs should be inspected twice a year — typically in spring and fall.
🔒 Benefits of Regular Commercial Roof Inspections:
- Detect hidden leaks before they damage insulation or ceilings.
- Meet warranty and insurance requirements.
- Extend roof lifespan by 5–10 years.
- Support budget forecasting for maintenance or replacement.
