Hailstorms are among the most unpredictable and damaging weather events for commercial buildings. While many property owners focus on protecting roofs, siding, and windows, one critical component often overlooked is roof-mounted HVAC equipment.
Damage to rooftop HVAC systems from hail can lead to costly repairs, system failures, business interruption, and long-term energy inefficiency. At Risk Assured, we help facility managers and property owners take proactive steps to safeguard this high-value equipment from extreme weather.
Why Rooftop HVAC Units Are at High Risk During Hailstorms
When hail strikes coil assemblies or fan components, it can compress delicate fins, damage blades, or puncture key structural elements. Over time, this damage accumulates, reducing airflow, decreasing system efficiency, and potentially causing full unit failure.
Most Vulnerable Equipment Includes:
Condenser coils and fan blades on HVAC units and chillers
Cooling tower fill media and fans
Upright heat exchanger coils
Exhaust vents for air handlers and makeup air units
Exhaust fans and rooftop ductwork
The Cost of Hail Damage Goes Beyond Equipment Repairs
Even minor hail impacts can shorten the lifespan of HVAC units and degrade performance. In many cases, the downtime and productivity loss caused by a damaged system can exceed the actual repair or replacement costs. Business continuity, occupant comfort, and critical building functions all depend on reliable HVAC systems—making hail protection a top priority.
Be Proactive: Install HVAC Hail Guards
One of the most effective ways to minimize hail damage is to install hail guards—protective barriers that shield vulnerable components without blocking airflow. Hail guards are available in various designs and materials, each tailored to specific HVAC configurations.
Common Hail Guard Solutions:
Coil-based protection systems: Use aluminum frames with galvanized steel mesh or louvered panels
Semi-rigid composite barriers: Configured in lattice or square patterns for balanced protection
Hail netting and intake filter screen systems: Feature galvanized frames with fiber-reinforced filters
Three Ways to Implement HVAC Hail Protection Solutions
Your approach will depend on whether you're outfitting a new building or retrofitting existing equipment:
1. Purchase HVAC Units with Built-In Hail Protection
When installing new systems, select models that include factory-installed hail guards. These are designed specifically for the unit and can often be color-matched to your building’s aesthetics.
2. Retrofit Existing Rooftop Equipment
Contact the original equipment manufacturer (OEM) to determine if aftermarket hail guard kits are available. Some third-party vendors also offer customizable retrofit solutions that integrate with various HVAC models.
3. Consult a Specialist
Unsure which route to take? Reach out to a qualified HVAC professional or risk advisor to evaluate your options and recommend a solution that meets both your protection needs and local building codes.
Key Installation and Maintenance Tips
Whether you're installing new guards or retrofitting existing equipment, keep these best practices in mind:
Only allow licensed and insured professionals to handle the installation
Do not mount hail guards directly against coil fins, as this can restrict airflow
Ensure all guards are securely fastened to prevent wind-related movement or detachment
Routinely inspect and clean hail guards to prevent debris buildup and airflow obstruction
Monitor system performance after installation to detect any changes in efficiency
Include hail guard installation in contractor agreements and require adherence to OSHA fall protection and industry safety standards
Protect Your Investment and Ensure Operational Continuity
Your rooftop HVAC equipment is a critical asset. Without proper protection, hail damage can compromise your building’s climate control, energy efficiency, and overall performance. Investing in high-quality hail guards and professional installation can help you avoid costly repairs, unexpected downtime, and insurance claims.
At Risk Assured, we partner with commercial property owners and facility managers to create comprehensive protection plans that safeguard their HVAC systems and other weather-sensitive equipment.

AQ: How to Protect Roof-Mounted HVAC Equipment from Hail Damage
1) Why is hail protection important for roof-mounted HVAC systems?
Roof-mounted HVAC units are exposed to direct impact from hailstorms, which can dent coils, damage fans, and cause refrigerant leaks. Protecting them reduces repair costs, downtime, and system inefficiencies.
2) What types of hail damage commonly affect HVAC units?
Hail can damage condenser coils, fan blades, protective fins, and electrical components. Even small dents can restrict airflow, lower energy efficiency, and shorten equipment lifespan.
3) How can businesses protect HVAC equipment from hail damage?
Install hail guards, protective mesh screens, or metal grilles over condenser coils. Choose impact-resistant materials and regularly inspect roof-mounted equipment for signs of wear or prior damage.
4) What are hail guards, and how effective are they?
Hail guards are metal or polymer mesh shields designed to absorb and deflect hail impact without restricting airflow. When properly installed, they significantly reduce damage risk and maintenance costs.
5) Can protective coatings help prevent hail damage?
Yes. Protective coatings applied to coils and housings can help absorb impact and prevent corrosion, enhancing both durability and system performance.
6) How often should roof-mounted HVAC systems be inspected for hail damage?
Inspections should be conducted after every major hailstorm and as part of regular semi-annual maintenance to ensure any hidden damage is identified early.
7) Does insurance cover hail damage to HVAC units?
Most commercial property insurance policies cover hail damage, but some may have exclusions or deductibles specific to roof-mounted equipment. It’s essential to verify coverage details with your insurer.
8) What are the costs of not protecting HVAC equipment from hail?
Unprotected systems face costly repairs, reduced efficiency, and shortened service life. Hail damage can also lead to HVAC downtime, disrupting business operations.
9) How does hail damage impact energy efficiency?
Dented fins and coils restrict airflow, forcing the HVAC system to work harder to maintain temperature—resulting in higher energy bills and increased wear and tear on components.
10) How does Risk Assured help businesses minimize hail damage risks?
Risk Assured provides engineering-grade risk assessments, protective system design reviews, and hail mitigation strategies to help property owners safeguard HVAC equipment and reduce long-term maintenance costs.
