Our Top 3 Picks
Why Roof Heating?
Before getting into our list, here’s a quick explanation of why roof heating is important for commercial buildings:
Energy Efficiency
Roof heating systems help maintain the integrity of a building’s structure by preventing ice dams and reducing snow load. They improve a building’s heat retention leading to better energy efficiency and lower heating costs.
Snow and Ice Prevention
Accumulated snow and ice cause several problems, including roof damage, leaks, and safety hazards.
A reliable roof heating system minimizes these issues, making your building safer for occupants and visitors.
Roof Longevity
Continuous exposure to snow and ice causes wear and tear on your roof. A weatherproof roof heating system prevents this and prolongs its lifespan.
Best Roof Heating Systems For Commercial Buildings
Here are the best types of roof heating systems available for commercial buildings.
Each system has unique features and benefits, but all have been chosen for their efficiency, reliability, safety and ease of use:
1. Electric Heating Cables
Electric heating cables, often referred to as heat tape, are a popular and straightforward type of roof heating system for commercial buildings.
You can install them along roof edges, gutters, and downspouts to prevent snow buildup and ice dams. As they emit direct heat, they melt snow and ice on contact to keep water flowing freely off your roof and through your drainage system.
There are two main types of electric heating cables: constant wattage and self-regulating.
Constant wattage cables offer steady heat regardless of the temperature. This makes them less energy-efficient and the best for areas with consistent cold weather. Self-regulating heating cables adjust their heat output based on ambient temperatures, increasing efficiency by using less power when the weather is milder.
Electric heating cables are a simple and reliable roof heating system for commercial applications as they are easy to install and suitable for retrofitting without major modifications.
Pros
- Easy to install and retrofit
- Durable and reliable in harsh weather
- Reduces the risk of ice dams and roof damage
Cons
- Needs continuous power supply
- Periodic maintenance
Best For: Small to medium-sized commercial buildings.
Rating 5/5
2. STEP Roof Deicing System
The STEP roof deicing system uses low-voltage, self-regulating heating elements to melt snow and ice on roofs. A thin, flexible design makes it particularly beneficial for commercial roofs with irregular shapes or small areas that are hard to get to.
As the system automatically adjusts its power output, it prevents overheating and thermal damage. This adaptability also results in 30-60% lower energy consumption compared to traditional deicing cables.
It operates on a safe 24-50V AC/DC power supply, eliminating the need for complex grounding setups.
This system is compatible with various roofing materials and carries a 10-year outdoor use warranty, ensuring long-term reliability and performance.
Pros
- Easy to install
- Energy efficient
- No complex grounding
Cons
- Professional installation recommended
- Can be difficult to retrofit
Best For: Buildings with complex roof designs.
Rating: 5/5
Tired of Ice Dams Damaging Your Commercial Roof?
3. Hydronic Heating Systems
Hydronic heating is a cost-effective system that circulates hot water through a network of pipes installed beneath the roof surface. As the hot water flows through the pipes, it radiates heat upwards, melting snow and ice.
These systems are particularly effective for large commercial buildings needing extensive snow and ice management. They offer uniform heat across large areas, so there’s little risk of hotspots developing.
You can integrate them with existing heating systems, such as boilers, to reduce installation costs.
On the downside, installing a hydronic system involves a large upfront investment. You also need careful pipe design and layout for optimal heat distribution and to avoid leaks. While they are low-maintenance once installed, you might have to get them professionally serviced.
Pros
- Reduces long-term operating costs
- Uniform heat distribution
- Integrates with existing heating systems
Cons
- High initial installation cost
- Professional fitting
- Potential for leaks or maintenance issues
Best For: Large commercial buildings
Rating: 4/5
4. Solar Roof Heating Systems
Solar roof heating systems use solar panels to generate heat, which is then transferred to the roof to melt snow and ice. This system is gaining popularity as a sustainable and energy-efficient roof heating solution.
As solar heating systems use a renewable energy source, they reduce reliance on electricity and lower utility costs. They work best in regions where sunlight is plentiful.
The system is typically made up of solar panels, a heat transfer fluid, and a series of pipes or coils installed beneath the roof surface. The solar panels collect and convert sunlight into heat, warming the fluid circulated through the pipes to melt accumulated snow and ice.
While initial installation costs are high, the long-term savings and environmental benefits make solar an attractive option for eco-conscious businesses.
Pros
- Renewable energy reduces carbon footprint
- Lower operating costs
Cons
- Dependent on weather conditions
- High installation costs
Best For: Sunny regions and those seeking sustainable solutions
Rating: 3.5/5
What To Consider?
Here are some elements to consider when choosing your roof heating system to ensure optimal performance and cost efficiency
Building Size and Type
The size and type of your building determine which heating system is most effective.
Larger buildings with expansive roofs benefit more from hydronic or hot water systems, while smaller buildings could make do with electric or self-regulating cables.
Roof Type
Not all roof heating systems are compatible with every roof type, so make sure the system you choose matches your roofing material.
Climate and Weather Conditions
Different systems perform better in specific climates.
For instance, self-regulating cables are ideal for areas with variable temperatures, while solar systems are best suited to sunny locations.
Energy Consumption
It’s important to consider the long-term energy consumption of each system. For example, hydronic systems are costly to install but provide good energy efficiency in the long run.
Installation and Maintenance Costs
Initial installation costs vary between systems. However, it’s also important to factor in ongoing maintenance expenses.
Pitfalls To Avoid
Here are some pitfalls to avoid when choosing your commercial roof heating system:
- Systems without proper weatherproofing.
- Products that need frequent maintenance or have a history of reliability issues.
- Overly complex systems that need specialized installation and maintenance knowledge.
- Heating solutions incompatible with your building’s existing infrastructure.
Avoid Costly Mistakes In Roof Heating Selection
Frequently Asked Questions
How often do roof heating systems need maintenance?
The maintenance frequency depends on the system type. Electric cables may require annual checks, while hydronic systems need regular monitoring of the water source and plumbing.
Can roof heating systems be installed on existing roofs?
Yes, most roof heating systems can be retrofitted to existing roofs. However, the complexity and cost will vary depending on the roof type and the chosen heating system.
Are there any safety concerns with these systems?
When properly installed, roof heating systems are generally safe. However, electrical systems need regular checks to prevent electrical faults, and hydronic systems should be monitored to avoid leaks.
How long do roof heating systems typically last?
With proper maintenance, most roof heating systems can last 10-20 years or more. The lifespan will depend on the system type and maintenance level.
