HEATIT Roof & Gutter De-Icing Cable 240 ft — 5W/ft Constant-Wattage, XLPE Insulated

HEATIT HIRD 240FT is a 5W/ft constant‑wattage roof and gutter de‑icing cable engineered to prevent ice dams and keep gutters, downspouts, and roof edges clear of ice.

When winter weather packs snow and freezing rain onto your roofline, ice buildup can block gutters and form destructive ice dams. The HEATIT HIRD heat tape delivers steady heat along roof edges, gutters, and downspouts to promote uninterrupted meltwater flow and reduce the risk of pooling and freeze‑thaw damage. Built with thick XLPE insulation, full aluminum foil screening, and a tinned copper braid, this cable is ETL and CSA certified for safety and durability across North America.

How does this cable keep gutters and downspouts flowing?

The cable supplies consistent 5 watts per foot of heat to the contact surface, melting accumulated ice and snow so water can escape into the drainage system. It’s designed for direct installation in gutters, along roof eaves, or inside downspouts to form melt channels that prevent blockages.

• Constant‑wattage output for predictable heat along the entire 240 ft length
• Suitable for metal and plastic gutters and standard noncombustible roof shingles
• Can be run in a zigzag pattern across roof valleys or straight through downspouts
• Helps reduce weight and pressure from ice buildup on gutters

Is this cable safe and easy to test before installation?

Yes. The HIRD cable is fully ETL and CSA certified and includes a UL‑certified plug, giving comprehensive component and cable safety verification. Before you install, uncoil the entire length, keep it separately laid out, plug it in briefly to confirm it warms, then unplug and proceed with mounting.

• ETL & CSA third‑party certification for the full cable
• UL‑certified plug for added electrical safety
• Simple pre‑installation warm test: uncoil, plug, feel mild warmth, unplug
• Detailed mounting guidance helps avoid overlaps and hot spots

What construction features make it durable in harsh weather?

The cable uses tough XLPE inner insulation and a protective outer jacket to resist abrasion, moisture, and UV exposure. Internally it includes 100% aluminum foil screening plus a tinned copper braid to improve grounding, reduce electrical interference, and extend service life under freeze/thaw cycles.

• XLPE inner insulation for mechanical strength and thermal stability
• Aluminum foil plus tinned copper braid for full screening and durability
• Robust outer jacket tolerates outdoor exposure and installation stress
• Designed for repeated seasonal use and long service life

How should I plan the layout and length for my roofline?

Measure the total gutter run, valley lengths, and downspouts to determine if 240 ft covers your needs or if additional runs are required. The cable is sold as a continuous 240 ft length and can be arranged in straight or zigzag patterns; account for anchoring points and avoid overlaps to maintain performance.

• Measure eaves, valleys, and downspouts before ordering
• Allow slack for bends and secure clips; do not overlap the cable
• Use zigzag placement across roof valleys for wide areas, straight runs inside downspouts
• Follow pre‑installation warm test and manufacturer mounting instructions

Who is this for? Homeowners and property managers in cold climates who want a reliable, certified solution to reduce ice dams, clogged gutters, and roof edge ice buildup will benefit from the HEATIT HIRD 240FT de‑icing cable. It suits residences with noncombustible shingles, commercial buildings with accessible gutters, and anyone seeking a tested, long‑lasting heat tape to preserve roof and drainage system performance during winter months.
