What Are Snow Guards and Why Are They Important?
Snow guards are devices installed on rooftops to hold snow and ice in place. Without these, accumulated snow can suddenly slide off roofs in large sheets, which can lead to serious damage. These guards disperse the snow load, allowing it to melt gradually or break into smaller, less harmful pieces.
They are especially vital in regions with heavy snowfall during winter, such as mountainous areas and northern states. Snow guards protect roofs, gutters, landscaping, and, most importantly, people and vehicles around the property.
Types of Snow Guards Commonly Used on Roofs
Several snow guard designs suit different roof types and snow load considerations. Choosing the right type is essential for effective snow retention.
Metal Bracket Snow Guards
These are sturdy, often made of aluminum or steel, and are attached directly to the roof. They are best for steep roofs and heavy snow loads.
Snow Fence Guards
These spread across the roof like a fence, distributing snow evenly and preventing large chunks from sliding.
Plastic or Composite Pads
Soft and less intrusive visually, pads attach to the roof to create friction and hold snow in place. They are usually installed in patterns for effectiveness.
Pipe Snow Guards
This style uses horizontal pipes to block snow movement. It’s common in commercial buildings or roofs with large surface areas.
Materials Used in Snow Guards
The material influences durability, appearance, and strength of snow guards. Each material has distinct advantages:
- Aluminum: Lightweight and resistant to rust, suitable for most residential roofs.
- Stainless Steel: Extremely strong and corrosion-resistant, ideal for extreme weather conditions.
- Plastic/Polycarbonate: Affordable, UV resistant, and available in various colors to match roofing.
- Copper: Durable and aesthetically pleasing, often chosen for upscale roofing but pricier.
How to Properly Install Snow Guards on Roofs
Installation requires precision to ensure snow guards function correctly without damaging the roof. Consider these steps:
- Assess the Roof: Know the roof pitch, material, and typical snow load.
- Choose the Right Type and Material: Match to the roof style and climate demands.
- Determine Spacing: Depending on the size and weight of snow, guards are spaced strategically to hold the snow load efficiently.
- Secure Attachment: Fasteners must be installed properly without causing leaks or weakening shingles.
- Professional Installation: Hiring experienced roofers is recommended to guarantee safety and effectiveness.
Benefits of Installing Snow Guards on Roofs
The primary advantage of snow guards is preventing sudden, heavy snow slides that can cause serious damage or injury.
- Protect gutters and roofing from snow damage.
- Prevent injury to people walking near the building.
- Avoid damage to vehicles and landscaping underneath.
- Help manage water flow by controlling snow melt.
- Enhance the overall safety and longevity of the roof.
Cost Considerations and Maintenance
The cost of snow guards varies depending on type, material, and roof size. Typically, prices range from $5 to $20 per guard unit, with professional installation adding to the overall expense.
Regular maintenance involves checking for loose fixtures, debris buildup, and addressing any damage caused by harsh weather. Well-maintained snow guards can last decades.
Choosing Snow Guards Based on Roof Types
| Roof Type | Recommended Snow Guard Type | Material Preferences |
|---|---|---|
| Metal Roof | Bracket or pipe style for secure holding | Aluminum or stainless steel for durability |
| Asphalt Shingle | Pad or bracket guards installed carefully | Plastic or aluminum to avoid roof damage |
| Tile Roof | Snow fences or carefully installed pads | Copper or aluminum, considering roof fragility |
| Flat Roof | Pipe style or snow fences | Stainless steel or aluminum for strength |
Snow Guards and Roof Warranty Considerations
Some roofing manufacturers may void warranties if snow guards are improperly installed or non-approved types are used. Always consult roofing warranty documents before installation and consider professional advice to maintain warranty integrity.
