Built with durable construction and IP68 waterproof rating, this roof heat cable is engineered for safe, long-lasting use in the harsh winter conditions.
  
• Convenient & Smooth Installation: MeltLogic Smart Controllers and cables are designed to accommodate self-installation or professional installation. MeltLogic does not provide installation, but many local contractors or roofers offer professional heat cable installation services for a fee.
• Installation Hardware & Materials: The pre-assembled heat cable is easy to install, with options for spiral wrapping, cross-wrapping, or straight-line placement. It is compatible with a wide range of roofing materials, including metal, rubber, wood, asphalt, clay, synthetic, and composite. Shingle clips and hangers are provided with all cable purchases. Reach out to your local roofer or contractor if you need professional installation. Shingle clips and hangers, designed to work on common shingled roofs, are provided with all heat cable purchases. MeltLogic does not provide installation hardware or adhesives for other types of roofs, but many other online retailers sell these common items.
• Beat the Winter: Treat your gutters and roof right and stand up to the harshest winters. Our self-regulating heat cable with 6FT power cord is designed to prevent ice dams from forming on roofs, downspouts, and in gutters. Protect your roof from damage and leaks, and keep the water flowing in the gutters and downspouts continuously.
