Constant monitoring of snow accumulation on roofs
Monitoring snow accumulation on roofs is crucial to maintaining structural safety and preventing costly damage. In areas prone to heavy snowfall, the weight of accumulated snow can strain roofing structures, leading to stress, deformation, or even collapse. Real-time monitoring allows property owners to detect when snow loads reach critical levels, ensuring timely action, such as snow removal, to protect the integrity of the building.
An additional benefit of remote snow monitoring is ice dam prevention, which protects against leaks and water damage. By utilizing advanced technologies like the Prylada snow load monitoring system, property owners can eliminate the need for manual roof inspections, which are often time-consuming and costly. With Prylada's solution, building maintenance becomes more efficient, reducing the risk of structural damage, extending roof lifespan, and lowering repair and upkeep expenses.

Catering to your monitoring needs
We tailor our solution to your specific environment, focusing on three key parameters:
Prylada uses two primary measurement approaches, each capturing a different layer of structural reality. They work independently or, for maximum accuracy, together.
Inclinometers are mounted at key structural support points under the roof. They measure angular displacement in real time, capturing exactly how the roof bends and responds to load, at each monitored point.
- Direct measurement of structural deflection
- Compact and weatherproof — no structural modifications needed
- 24/7 data stream with configurable alert thresholds
- Ideal for verifying structural calculations against real behavior
- Reasonable price
Radar is placed on the roof surface to measure the height of accumulated snow across multiple layers, enabling accurate calculation.
- Multi-point measurement across the full roof surface
- Summarizes information to calculate the total load
- Reasonable price
Used together, they give you what neither can provide alone
The inclinometer tells you how the structure is reacting. The radar tells you what is causing it. Combined, you get a complete picture: not just that the roof is under load, but also how much snow is present, where it is distributed, and what that means for structural safety.
Every facility is different. Some clients start with inclinometers alone, others prioritize snow characterization first. We configure the right setup for your specific roof, budget, and risk profile.

Dynamic mode switching in snow load monitoring
Prylada ensures precise snow load monitoring by dynamically adjusting measurement frequency based on snow accumulation levels, helping prevent structural risks. How It Works:
The system measures roof load at low frequency under normal conditions, minimizing energy consumption.
Once snow load stabilizes or decreases, the system automatically reverts to low-frequency mode, ensuring efficient power use.
When snow accumulation reaches a predefined critical weight, a hardware-triggered switch increases measurement frequency.
The system performs high-frequency measurements to assess snow load changes and potential structural risks.
This hardware-level adaptive monitoring enables proactive structural safety management without excessive power drain.
Ensure your roof is safe. Complete the form, and we’ll recommend the best snow load monitoring solution.
How much does snow weigh on a roof? Snow load threshold
The depth of snow on the roof is not the main indicator. Are you aware that wet snow applies greater pressure compared to powdery snow? It's crucial to consider both the thickness of accumulation and the type of snow. Additionally, factors such as roof shape and age play significant roles in risk assessment. Commercial buildings exceeding 5,000 square feet per floor and over 10 years old are especially vulnerable to potential collapse.

Most large‑area roofs carry equipment that was installed without accounting for winter snow loads. When snow accumulates, it doesn't just press on the structure — it interferes with everything else up there too.
Snow accumulates on and around panels, reducing energy output — sometimes to zero. Panels also change how snow distributes across the roof surface, creating uneven load pockets that are hard to assess without sensors. Manual clearing risks panel damage, and is often simply not feasible at scale.
Rooftop HVAC systems are among the heaviest permanent installations on flat roofs. Snow packs around intake and exhaust vents, reducing airflow and forcing units to work harder or fail. In some cases, snow melt and refreeze cycles block drainage and accelerate corrosion of mounting structures.
Communication antennas and satellite dishes are wind-exposed and sensitive to ice loading. Snow accumulation adds unexpected weight to mast mountings, and ice formation on dishes disrupts signal quality. These are typically the last items anyone thinks to check during a winter inspection.
Sprinkler pipes and suppression system components routed through or across rooftop spaces are vulnerable to freezing. Snow accumulation around access hatches and mechanical penetrations can block emergency access, precisely when it matters most.
The common thread: you don't know until something fails
None of these issues announce themselves. PV output drops gradually. HVAC efficiency degrades quietly. Structural load accumulates invisibly. Snow load monitoring gives you one continuous, reliable signal — the structural response of the roof itself, so you can act before equipment is damaged or access is lost.
Planning any rooftop installation?
Install snow load monitoring before or alongside your solar panels. Know exactly how your roof responds to the combined load — in real time, all winter long.
