Choosing the right installation system for hail netting is just as important as choosing the net itself. The structure you select affects wind resistance, hail discharge, fruit quality, and long-term maintenance costs.
In commercial orchards and vineyards, the two dominant installation types are Flat (Canopy) and Pitched/Tent (Roof) systems.
As a manufacturer with 30 years of experience in orchard protection solutions, EyouAgro explains how each system works, its advantages, and how to make the correct choice based on your crop and climate.
Why Installation Method Matters
Before comparing systems, it’s essential to understand why installation type plays such a critical role:
- It determines the safety of your orchard under strong winds.
- It affects hail discharge efficiency, preventing a heavy load from being placed on the net.
- It influences light distribution, temperature, and fruit quality.
- It impacts installation cost, structural durability, and maintenance cycles.
A well-designed structure can extend the net’s lifespan from 5 years to 8–10 years or more.
Which Hail Netting Installation Method Should You Choose?
The choice between a canopy or roof installation depends on several key factors:
- Wind conditions
- Local climate
- Crop type
- Budget and installation complexity
- Regional preferences and practices
Both systems can provide excellent protection when installed correctly, but each performs differently under specific environmental conditions.
Regional Preferences and Customer Practices
Different regions have developed their own installation habits over the years, often based on climate patterns:
- Europe & South America → usually prefer roof (pitched) structures
- Australia & New Zealand → commonly use canopy (flat) systems
This difference is practical:
- Roof installations are better suited to regions with frequent strong winds
- Canopy installations are typical in areas with milder, more predictable weather
Understanding what local growers use can help guide your decision, especially if your farm faces similar conditions.
Wind Resistance and Structural Design
The structural design of your hail netting system plays a significant role in determining its durability and long-term performance.
Roof (Pitched/Tent) Installation
A roof installation features a sloped top that allows it to deflect wind more effectively:
- Handles winds of 15–25 m/s
- Sloped design reduces uplift force by 30–45%
- Provides better stability in storm seasons
This makes it ideal for orchards in windy regions or areas with sudden weather changes.
Canopy (Flat) Installation
A canopy installation has a flat design and is easier and more economical to set up:
- Performs best in regions with winds below 12–15 m/s
- A flat surface is more sensitive to uplift pressure
- Requires proper tensioning of 25–35 kg to stay stable
- Suitable for farms with calm or predictable weather patterns
Farmers in mild climates often find the canopy system sufficient, while those in storm-prone regions typically choose the roof system for added structural safety.
Hail Discharge Performance
The way each system handles hail accumulation also differs:
Flat (Canopy) System
- May accumulate hail or snow on the net surface
- Requires a micro-slope of 5–10° to help discharge
- Not ideal for heavy hail regions
Roof (Pitched) System
- Designed with a 10–25° slope
- Enables 100% natural hail discharge
- The net surface does not bear the weight of ice
- Dramatically reduces the risk of collapse or tearing
Because of this, a roof system is strongly recommended in areas with medium to heavy hail.
Light Distribution & Microclimate
Different structures create different microclimates under the net:
Flat System
- More even light distribution: ±5% variation
- Ideal for light-sensitive crops
- Better for uniform growth and fruit coloration
Roof System
- Slightly more shading variation: ±10–15%
- Better airflow → reduces canopy temperature by 1–2°C
- Helps prevent heat accumulation in hot seasons
Cost & Installation Efficiency
Flat System
- Lower structural cost → typically 15–30% cheaper
- Faster installation: 300–500 m²/day for an experienced team
- Simplified tensioning and fewer components
Roof System
- Stronger and more complex structure
- Higher upfront investment, but
- Maintains stability 20–30% longer
- Lower long-term maintenance
Summary
- Flat = best for budget, speed, and mild climates
- Roof = best for durability, airflow, and stronger weather conditions
Consult Local Experts and Professionals
To ensure the best performance, always consult local installation experts or agricultural professionals:
- They understand local wind levels
- They know how soil conditions affect anchoring
- They can assess hail and rainfall patterns
- They can recommend the most suitable tension and structure
This ensures your system is correctly designed, installed, and maintained.
Flexibility and Customization Options
Both canopy and roof installations can be customized for:
- Orchard or vineyard spacing
- Row width and height
- Crop type (apples, pears, grapes, cherries, etc.)
- Land size
- Budget and long-term plans
For example:
- Apples, pears → often better with roof systems in windy regions
- Grapes → both systems depending on bird pressure & wind
- Cherries → typically require roof-rain cover systems to avoid rain cracking
Your crop type and climate will directly influence the best choice.

FAQ – Hail Netting Canopy vs Roof Installation
Which hail netting system is better for windy areas?
The roof system performs better in windy regions because it handles 15–25 m/s winds with reduced uplift pressure.
Its sloped structure disperses wind load much more efficiently than a flat canopy.
Does a flat canopy hold hail or snow?
Yes — a flat canopy may accumulate hail or snow if the surface is completely horizontal.
It requires a 5–10° micro-slope to allow natural sliding and prevent load buildup.
How much slope is needed for a roof-style hail net?
A roof-style system typically needs 10–25° of slope.
This angle ensures 100% natural hail discharge and keeps the net surface free from ice weight.
Is a canopy installation cheaper than a roof installation?
Yes — canopy installations are usually 15–30% cheaper and faster to set up.
They have simpler structures and require fewer heavy components.
Can I install hail netting without steel poles from the supplier?
Yes — steel poles, wires, and anchors are usually locally sourced to reduce freight costs.
EyouAgro provides a full BOM list so you can buy the exact materials in your region.
What tension should hail netting be installed at?
Most hail netting should be installed at a tension of 25–40 kg.
This prevents fluttering in the wind while avoiding overstress that could tear the fabric.
Which system is recommended for apples vs cherries?
Apples → Roof system, especially in windy or heavy-hail areas.
Cherries → Roof rain-cover system, because cherries are sensitive to rain cracking and need fast water discharge.
Why should we buy poles and wires locally instead of from you?
These items are heavy and expensive to ship overseas.
Buying them locally reduces freight costs by 70–90% and makes compatible materials and hardware easier to access.
What accessories do you include with the netting?
We provide:
- Clips & connectors
- Anti-billow fasteners
- Wind locks
- Custom cut-to-length netting
These items ensure your system matches the chosen installation method.
Conclusion
Choosing between a canopy and roof installation is essential for ensuring the protection and long-term reliability of your hail netting system.
- Roof installations offer superior wind resistance, better hail discharge, and long-term stability—ideal for areas with strong winds or heavy hail.
- Canopy installations provide a more straightforward, faster, and more economical solution, suitable for farms in mild climates.
Your best choice will depend on your local climate, crop type, and advice from local professionals.
