200ft Roof Heat Cable 5W/ft - Prevents Ice Dams, 120V

In this review of the 200ft Roof Heat Cable 5W/ft the bottom line is straightforward: this cable is for homeowners or contractors who need a reliable, certified solution to prevent ice buildup in gutters and downspouts. The reviewer found the cable especially valuable for metal or plastic gutters and roofs with noncombustible shingles because it combines ETL & CSA certification and a consistent 5 w/ft output, making it a practical choice where safety and steady heat output matter most.

Key Features

• Full certification: ETL and CSA certified cable with a UL plug offers comprehensive safety assurance for outdoor roof applications.
• Constant wattage: The 5 w/ft constant output maintains steady heating to limit ice dam formation and keep water moving in gutters.
• Durable construction: XLPE inner insulation and a weather-resistant PVC jacket help the cable withstand outdoor winter exposure.
• Complete kit: Includes a 6 ft 18/3 cold lead with plug plus clips and spacers to simplify routing in gutters and along roof edges.
• Versatile lengths: Available up to 240 ft so the 200 ft option covers long eaves, multiple gutters, or extended downspouts without splicing.

Who It's For

The cable is best for homeowners with inclined roofs, asphalt or other noncombustible shingles, and metal or plastic gutters who want an energy-efficient, certified heat tape to reduce ice dams and frozen downspouts. It also suits installers and contractors who prefer a fully certified product for building-code compliance.

It is less appropriate for flat roofs that do not direct runoff into gutters, or for installations where an integrated roof-melt system is required by local code; in those cases a different heating approach or professional consultation may be needed.

Pros & Cons
