Technical Roof Inspection for Solar Power Plants: When It Is Mandatory
Installing a solar power plant on the roof of a building is a complex engineering process that requires an assessment of the load-bearing capacity of the structures. Technical roof inspection for solar power plants is a key stage that helps determine whether the equipment can be installed safely and helps prevent emergency situations.
Under Ukrainian legislation, including the Law of Ukraine “On Regulation of Urban Development Activities” and applicable State Building Codes, structural inspection is mandatory in a number of cases, which are discussed below.
When a Technical Roof Inspection Is Mandatory
1. When the load on the structures changes
The installation of a solar power plant creates additional permanent and wind loads on the roof. If:
- the building was not designed for such loads;
- there are no up-to-date structural calculations;
an inspection is mandatory to confirm structural reliability.
2. For buildings in operation for more than 20–30 years
Older buildings may have:
- worn load-bearing elements;
- corrosion of metal structures;
- cracks or deformations.
In such cases, the technical condition of the roof must be confirmed by an expert technical opinion.
3. During reconstruction or major repairs
If the solar power plant is installed as part of:
- reconstruction;
- technical re-equipment;
- major repair works,
the technical inspection forms part of the project documentation.
4. For commercial and industrial facilities
Legal entities installing solar power plants:
- for the sale of electricity;
- to support production operations;
must comply with enhanced safety requirements. Without an inspection, it may be impossible to pass expert review or obtain the required permits.
5. At the request of the designer or regulatory authorities
Even if the facility is new, the design organization or regulatory authorities may require an inspection to:
- confirm the actual condition of the structures;
- clarify design parameters.

What a Technical Roof Inspection Includes
A technical inspection before installing a solar power plant usually includes:
- visual inspection of structures;
- instrumental measurements;
- assessment of load-bearing capacity;
- inspection of fasteners and the roofing layer;
- assessment of wind and snow load impact in accordance with DBN V.1.2-2:2006.
The result is a technical report used for solar power plant design.
Typical Mistakes When No Inspection Is Performed
Without a professional technical inspection, clients often face the following problems:
- roof overload and deformation;
- leaks caused by improper installation;
- refusal to approve the project;
- additional costs for structural reinforcement.
Practical Case
In practice, situations often occur where solar power plants are installed on warehouse or industrial buildings without prior analysis. After installation, the following issues may be identified:
- roof deflection;
- damage to waterproofing;
- the need to dismantle part of the solar power plant.
Such risks can be fully eliminated through a timely technical inspection.
How to Order a Technical Roof Inspection
To avoid risks, it is recommended to:
- Contact certified engineers.
- Conduct a full structural inspection.
- Obtain a technical opinion.
- Provide the data to the solar power plant designers.
It is also worth reviewing the service technical inspection of buildings and structures and the related service solar power plant design for a comprehensive approach.
Conclusions
A technical roof inspection for a solar power plant is not a formality, but a critically important stage that:
- ensures safe operation;
- helps prevent accidents;
- ensures compliance with Ukrainian legislation;
- optimizes construction costs.
