Eastrexon Roof & Gutter Heat Tape 152FT — 8W/ft Self-Regulating 120V De-icing Cable

Eastrexon 152FT Heat Tape is a self-regulating 120V roof and gutter de-icing cable (8W/ft) designed to prevent ice dams, keep gutters and downspouts flowing, and protect rooflines from freeze-related damage.

Built for cold climates and varied roof assemblies, this long-span heat cable combines a corrosion-resistant AL-MG alloy conductor, multi-layer safety construction, and a self-limiting (PTC) heating element to deliver targeted warmth where ice and snow normally form. It runs 152 feet and connects with a 9.8-foot power cord, offering flexible layout options for eaves, valleys, gutters, and downspouts while minimizing unnecessary energy use.

How does this cable stop ice dams on roofs?

The Eastrexon heat tape adds heat along eave edges, gutters, and downspouts to keep meltwater moving off the roof instead of refreezing at the edge. Its self-regulating characteristic raises heat output in colder spots and lowers it as temperatures climb, preventing hot spots and conserving energy.

• Constant 8 watts per foot power rating optimizes heat distribution.
• Self-regulating PTC core increases heat where cold is worst.
• Can be laid in zigzag or ladder patterns across critical areas.

Is it safe to overlap or cross sections of the heat cable?

Yes — the Eastrexon 120V self-regulating design tolerates overlaps without shorting or burning out, unlike fixed-resistance cables. Overlapping is useful for creating denser warming zones around valleys, gutters, or downspouts where ice accumulates most.

• PTC element prevents runaway current when cables overlap.
• Four-layer construction includes waterproof jacket and shielding for added protection.
• 100% screened AL-MG alloy wire reduces interference and enhances durability.

What installation and accessories come with the heat tape?

Eastrexon supplies 60 spacers and clips to secure the cable to roof edges, shingles, or gutter lips, and the cable is compatible with common mounting patterns for eaves and downspouts. The 9.8-foot power lead gives room to reach an outlet or GFCI-protected circuit without immediate extension cords.

• Includes 60 mounting clips and spacers for neat, secure fastening.
• Flexible for wrapping around downspouts or running along gutter bottoms.
• Installers can pair with thermostats or controllers (sold separately) for automated operation.

What safety features protect the cable and the roof?

The cable uses a durable outer jacket and insulation layers with tinned copper core and full shielding for weather resistance and electrical protection. It’s engineered to resist moisture and mechanical wear while delivering controlled heat to problem areas.

• Waterproof outer jacket repels moisture and sleet exposure.
• Four-layer build: jacket, insulation, shielding, and PTC heating layer.
• High screening rate and corrosion-resistant conductors for long life.

Who this is for: Homeowners, contractors, and property managers who need a dependable roof de-icing solution for long eaves, continuous gutter runs, or multi-story downspouts. Ideal for houses with metal, plastic, or non-combustible shingle roofs and for anyone wanting an energy-conscious, installable cable that resists overlap damage and simplifies winter maintenance.
