HEATIT HIRD Roof & Gutter De-Icing Cable 20ft — 5W/ft constant-wattage, ETL/CSA certified

HEATIT HIRD 20FT is a 5W/ft constant-wattage roof and gutter de-icing cable designed to prevent ice dams and keep gutters and downspouts clear.

Built for cold climates and winter maintenance, this 20-foot heat tape from HEATIT delivers steady, reliable warmth along roof edges, gutters and downspouts. The cable is ETL and CSA certified for full-system safety, and the construction uses XLPE inner insulation with aluminum foil screening and a tinned copper braid for durability. It’s meant to be used on noncombustible roofing materials and fits a range of gutter and roof layouts when installed according to instructions.

How does this cable stop ice dams and clogged gutters?

The HIRD cable melts snow and ice where it forms along roof eaves and inside gutters so meltwater can drain rather than refreeze. By maintaining a warmer strip along the critical edges, water flows to downspouts instead of building into ridges that cause ice dams.

• Constant 5W per foot heat output to maintain a consistent melt line
• Place along roof eaves, inside gutters, and downspouts for continuous drainage
• Works with common shingle roofs and metal or plastic gutters
• Prevents pooling and reduces risk of freeze-related overflow

Is the HEATIT cable safe and easy to test before installation?

Yes — the full cable assembly carries ETL and CSA certification for the cable and a UL-certified plug, ensuring thorough component testing. HEATIT includes clear pre-installation testing steps so you can confirm the cable warms correctly before securing it to your roof or gutters.

• Fully uncoil the cable so it does not overlap, then plug in briefly
• Cable should feel slightly warm within about five minutes during the test
• Certifications cover both cable and plug components for compliance
• Testing helps prevent damage from accidental overlap during installation

What materials and roof types are compatible with this heat tape?

The HIRD de-icing cable is designed for noncombustible roofing materials such as asphalt shingles and is suitable for use with metal or plastic gutters and downspouts. It is not intended for combustible roof coverings; always verify local building codes and manufacturer recommendations before installing.

• XLPE inner insulation and 100% aluminum foil screening for electrical protection
• Tinned copper braid increases mechanical durability and grounding
• Recommended for asphalt shingles and noncombustible roof assemblies
• Compatible with most standard gutter and downspout materials

How do I install and size the cable for my roof and gutters?

Select a length that covers the eave line, gutter channel, and downspout length you want to protect; HEATIT offers multiple lengths to match common configurations. Install the cable following the included instructions: test uncoiled, secure with approved clips, and avoid crossing or overlapping the cable.

• Measure eave, gutter, and downspout runs before ordering length
• Do not overlap cable; secure it with manufacturer-approved fasteners
• Perform the warm-up test prior to final mounting
• Follow local electrical code for power and grounding requirements
