HOW MUCH DOES A INSPECTION COST?
Commercial building inspections typically range from $1,500 to $10,000+, depending on the building's size, age, and complexity.
Most commercial inspectors use a square footage rate (averaging $0.10 to $0.30 per sq. ft.) or bill at an hourly rate of roughly $300/hr.
Typical Cost Breakdown by Property Size
Costs will vary significantly based on the type of facility you need inspected:
Small Buildings (< 10,000 sq. ft.): $1,500 – $4,000
Medium Buildings (10,000 – 50,000 sq. ft.):
$4,000 – $10,000
Large / Complex Buildings (> 50,000 sq. ft.):
$10,000+ (often priced by the acre or up to $0.50+ per sq. ft.)
For a massive 120,000 M2 - 1,291,669 SQFT Commercial building, a roof inspection will typically cost between $323,000.- and $646,000.-(or roughly $0.25.-to $0.50.- per sqft.
The final price primarily depends on the depth of the evaluation, roof accessibility, and whether specialized diagnostic technology is required.
Cost Breakdown by Inspection
TypeBase/Visual Inspection: \(\$3,000 – \$7,000\)A walkthrough checking for general wear, flashings, leaks, and roof penetrations.
Drone Survey & Analysis: \(\$5,000 – \$12,000\)
Highly practical for a building of this magnitude; uses high-definition photography to map out damage without putting workers at risk for such a vast area.
Infrared or Comprehensive Assessment: \(\
$10,000 – $30,000.-
Uses infrared thermal imaging to detect hidden trapped moisture under the roofing membrane, combined with core sampling to evaluate the underlying roof layers.
Key Factors That Drive the PriceRoof Pitch & Complexity: Flat, accessible roofs are cheaper to inspect than roofs with many angles, HVAC units, skylights, and parapet walls.
Type of Roofing Material: Specialized roofs require unique expertise and equipment to survey.Accessibility & Height:
Multi-story buildings requiring safety rigging or high-lift equipment increase labor rates.
To get a more precise and accurate estimate, several pieces of information are needed:
If you are interested, please provide the following details:What is the roof type (e.g., TPO, EPDM, metal)?
What is the number of levels/stories and its accessibility?
Are you requiring an insurance claim, a real estate transaction report, or general preventative maintenance?
Let me know what you are looking to accomplish so we can narrow down the specifics!
For a comprehensive building inspection and status assessment of a very large roof of 120,000 square meters, you should expect approximately 1 to 3 weeks of work.
The time is divided into 1–3 days for field work on site and 1–2 weeks of follow-up work for analysis and report writing.
Time required in detail The process for such a large commercial property is usually divided into the following phases:
Field work (Roof inspection):
1 to 3 days One or more certified inspectors need to go through the surface.
The exact time depends on how complicated the roof is.
Time formula:
For an area of 120,000 m², approximately 1,000 – 2,000 m² are normally inspected per hour, depending on the number of waterproofing layers, penetrations and roof safety.
For very complex surfaces, the roof can be divided into sections.
Sampling and special checks (if necessary): 1–2 days Includes any moisture measurements, thermography (thermal camera) to find hidden leaks in insulation or ocular pressure tests.
Analysis and report writing:
1–2 weeks The large amount of data, drone images, moisture measurements and any material samples are compiled into a complete maintenance plan or inspection report.
Factors affecting the total time Accessibility and safety: How the roofs are designed and what requirements there are for fall protection and sky lifts.
Complexity:
Number of dormers, ventilation units, pipe penetrations and roof drains that must be checked extra carefully.
Equipment:
Using a drone with a thermal camera, the ocular inspection is significantly more efficient compared to walking the entire surface manually.
To get an exact quote and schedule for your specific property, you can turn to experts in larger commercial properties.
You can explore services and consultants through SBR (Swedish Association of Civil Engineers) or through industry organizations such as Tätskiktsgarantier. If you want to delve deeper into what is required, please tell us:
What type of roof covering is involved (e.g. cardboard, canvas, sheet metal)?
What is the purpose of the inspection (status assessment, warranty inspection, or prior to solar cell installation)?
Then I can help you identify the right type of competence for the job.
Pricing Models Used by Inspectors
Per Square Footage:
The most common method.
The rate per square foot usually drops as the property size increases.
By the Hour:
Common for small commercial spaces or when the scope is strictly limited to one or two building systems.
Percentage of Sale Price: Sometimes used for very large/complex transactions (like a $10M+ shopping center) where the inspector leads a team of sub-consultants.
Factors That Will Increase the Cost
Expect higher quotes if your building requires:
Specialized Systems:
Elevators, commercial refrigeration, or complex industrial HVAC.Environmental Testing:
Phase I or Phase II Environmental Site Assessments (ESAs), asbestos testing, or mold inspections.
Roof Inspection:
Particularly if it requires rope access, drones, or involves older commercial roofing systems.
Detailed Engineering Reports:
If you require specialized structural, electrical, or plumbing engineers to sign off.
