HEATIT HIRD Roof & Gutter Snow De-Icing Cable 240 ft, 5 W/ft — ETL/CSA Certified, Plug-Ready

HEATIT HIRD 240 feet constant-wattage heating cable delivers 5 watts per foot to prevent ice dams and keep gutters and downspouts flowing when temperatures drop.

Designed for residential roof edges, gutters and downspouts, this pre-assembled heating cable is ETL and CSA certified and arrives ready to install with a 6-foot cold lead and plug. The cable's XLPE inner insulation, weather-resistant PVC jacket and full aluminum foil/tinned-copper braid shielding offer long-term durability in freeze/thaw conditions. Multiple lengths support a range of roof and gutter layouts, helping melt accumulated snow and prevent damaging ice buildup without complex controls.

How does this cable reduce ice dam formation on my roof?

The cable lays along roof edges and inside gutters to create a narrow, heated path that channels meltwater off the roof rather than letting it refreeze at the eave. By keeping the gutter and downspout clear, you reduce the pressure and leakage that can cause interior water damage. Installation along valleys and eaves where snow accumulates is especially effective.

• Constant 5 W/ft output provides steady low-voltage heat along the run
• Installs on metal or plastic gutters and on inclined noncombustible roof surfaces
• Pre-assembled 6 ft cold lead with UL-certified plug for immediate use
• Full shielding minimizes electrical interference and improves safety

Is the HEATIT cable safe and certified for residential use?

This heating cable is ETL and CSA certified, covering both the cable assembly and its performance to North American safety standards. The included plug is UL certified, and the cable construction uses robust XLPE insulation and a weather-resistant PVC outer jacket for long-term protection. Because it’s constant-wattage, it provides predictable heat output without requiring specialized controllers.

• ETL & CSA certified for full cable compliance
• UL-certified plug included for added protection
• Aluminum foil and tinned copper braid ensure 100% shielding
• XLPE and PVC layers for temperature and weather resistance

How do I install and test the HEATIT HIRD cable safely?

Installation is straightforward when you follow the included instructions and use the supplied clips and spacers to secure the cable. Uncoil the cable fully before powering to avoid overheating from overlaps. A simple pre-installation test — plug in after uncoiling and feel for slight warmth within about five minutes — confirms the cable is functioning before final mounting.

• Pre-assembled with 6 ft cold lead and plug for quick start
• Clips and spacers included for secure placement in gutters and eaves
• Always uncoil fully and test for warmth before final installation
• Do not overlap or cross the cable during installation

Which roofs and gutter systems are compatible with this cable?

The HEATIT HIRD cable works on metal and plastic gutters as well as on inclined roofs covered with noncombustible shingles that comply with local building codes. It's supplied in a long 240-foot length at a constant 5 W/ft output — suitable for extensive perimeter runs or multi-gutter setups. Select the proper layout so heat concentrates where ice forms: eaves, valleys, and downspouts.

• Suitable for asphalt and other noncombustible shingled roofs
• Works with metal and plastic gutters and downspouts
• Available lengths accommodate typical residential roof perimeters
• Designed to prevent water backup and subsequent roof damage

Who this is for: Homeowners and property managers who experience recurring ice dams, frozen gutters or blocked downspouts and want a certified, ready-to-install heating solution. It's a practical choice when you need a durable, constant-wattage cable that’s simple to test and mount along eaves, valleys and inside gutters. If you require professional assurance, consult a licensed installer to verify local code compliance and optimal placement for your roof configuration.
