Roof Load-Bearing Capacity Assessment

A roof load-bearing assessment is an analysis that determines how much load a roof structure can safely support – including both permanent loads (such as the roof’s own weight) and variable loads (such as snow, wind, maintenance personnel, or installed equipment).

Our assessment also includes a detailed description of the roof structure, including its dimensions, surface area, and the design loads originally assumed. We also analyze available archival documentation as part of the evaluation.

A roof load-bearing assessment is essential when you’re planning to install new equipment that adds weight to the roof structure – such as photovoltaic panels or suspended installations.

It ensures that your roof remains structurally safe for you and your employees after the installation. 

In such cases –  like PV system installations – a load-bearing assessment is legally required.

1. We begin by reviewing the documentation you provide. 
2. During an on-site inspection, we verify that the documentation matches the actual condition of the building, and we assess the current state of the roof structure and covering.
3. We then carry out a full inventory of the roof structure as well as any installations located on or beneath the roof.
4. We perform structural calculations to determine the load-bearing capacity and the available reserve capacity – to check whether the roof can safely support additional loads.

All of these steps are taken to deliver a precise and reliable roof load-bearing assessment tailored to your building.

If you’re planning to install photovoltaics, we also prepare a detailed panel layout plan. This plan is optimized to ensure both maximum efficiency and the safe operation of the roof structure.

• We prioritize safety – our specialists are certified to work at heights and operate aerial platforms. Safety is our top priority – both for our team and everyone present in the building during the inventory process.
• We minimize disruptions of daily operations – we plan and carry out the inventory with minimal impact on your daily operations, ensuring your business can continue to function as usual.
• Advanced technology for reliable data – we use specialized equipment, including tools for measuring sheet metal thickness, to ensure accurate and dependable results.
• Complete assessments even without full documentation – if your building lacks design records, we conduct a detailed on-site inspection to create a comprehensive and reliable structural assessment.

By using the SENSE S-One roof deflection monitoring system, you gain full confidence and control over your roof’s condition. The system continuously collects data on load, temperature, deflection, and other critical structural parameters. 

The data collected by SENSE S-One is transmitted directly to the SENSE Smart Roofs Platform – a web-based application accessible on your phone. This centralized dashboard provides you with all the essential information about your roof’s condition, enabling you to quickly detect warning signs and take timely action before minor issues develop into serious problems.

With the roof deflection monitoring system and the SENSE Smart Roofs Platform, you protect your investment and minimize the risk of damage or failure.

• We prioritize the safe use of your building after panel installation, especially during periods of snow accumulation.
• We take an individualized approach to each client’s needs and work diligently until we find the optimal solution.
• Every project includes an on-site inspection, and if design documentation is unavailable, we conduct a full structural inventory ourselves.
• We select the appropriate mounting system based on the roof covering and available load capacity.
• Safety for personnel working on the roof is a top priority – we ensure proper walkways and maintain safe distances from potentially hazardous areas.
• Our experience includes 48 completed roof structure analyses for flat roofs, covering a total area of 581,000 m².
