Roof & Gutter De-Icing

overview-roof-and-gutter-commercial Roof and gutters can be severely damaged by ice buildup. Ice dams and icicles form when the accumulated snow on a roof melts, and refreezes at the eaves and valleys during the evening. As the cycle continues and the ice dam continues to grow, it prevents the melted water from properly draining off of the roof. Eventually, icicles begin to form, increasing the chance for both structural damage and safety issues.

Roof & Gutter de-icing system

The roof and gutter de-icing systems maintain a continuous path for roof snow melt to drain from the roof through the gutter and downspout. We have a suite of solutions to meet your roof & gutter de-icing needs and budget. These de-icing systems are ideal for installation on:

  • Roofs made from standard roofing materials including shake, shingle, rubber, tar, wood, tile, slate, membrane, metal and plastic
  • Gutters made from standard materials including metal, plastic and wood
  • Downspouts made from standard materials including metal and plastic

nVent RAYCHEM Roof Ice Melt ( RIM / RIM2 ) System is our premier engineered, aesthetically elegant, concealed roof & gutter de-icing solution to prevent ice dams, icicles, and frozen gutter problems. The RIM system mechanically protects the self-regulating cable, provides high power output along the entire roof edge, and is ideal for new construction or renovation of buildings for all snow load areas.

RAYCHEM IceStop System is our high performing, self-regulating heating cable roof & gutter de-icing solution that automatically adjusts its power output to compensate for temperature variations. IceStop is often specified for commercial buildings and offers reliable state-of-the-art connection kits and control systems. These systems are ideal for buildings in light to heavy snow load areas.

Additional Components for roof and gutter de-icing systems include:

  • Connection kits and accessories – items for making reliable electrical connections and properly completing the installation, such as power connections, end seals and attachment clips and ties
  • Advanced control systems – devices such as thermostats, controllers and sensors, help trigger the system to energize when the ambient temperature is below freezing. This ensures that the roof de-icing system is energy efficient and maintains the temperature of the roof. These systems are also capable of communicating the performance to the Building Management Systems (BMS)
  • Power distribution system – electric panels for installations that require power distribution with single-phase or three-phase circuits

benefits-roof-and-gutter-commercial nVent’s nVent RAYCHEM roof & gutter de-icing systems prevent both ice dams and icicles from forming by creating a continuous path for roof snow melt to drain from the roof. While RAYCHEM roof & gutter de-icing systems are reliable and maintenance-free solutions, other solutions just don’t measure up.

Proven Technology

nVent is the world leader in heat-tracing solutions. We have sold over one billion feet of RAYCHEM self-regulating cable and are known for technical leadership and expertise in polymer science and radiation cross-linking. Self-regulating heat trace cable reduces heat output automatically as the roof and gutter heating cable warms to above freezing, resulting in lower energy output, and eliminating the possibility of overheating.

Reliable, Maintenance Free, Environmentally Clean Solutions

RAYCHEM systems utilize electric heat trace cables avoiding environmental and safety hazards, Hydronic systems rely on circulating warm fluids, such as a glycol-water mix which increases the risk of hazardous leakage and maintenance required. Our roof and gutter de-icing systems are low maintenance, durable, reliable and can handle severe wind speed, elevation, low temperatures and heavy snow load.

Chemicals, snow retention bars, cold roofs and shoveling are just temporary fixes that can lead to costly structural damage and personal injury.

Advanced Controls Systems

We offer the most advanced line of sensors and controllers with energy efficient technology and communication capabilities with building management systems to meet a wide range of design requirements.

Either of these controllers may be integrated into your Building Management System (BMS) using the RAYCHEM ProtoNode multiple protocol gateways.

Self-Regulating Technology

Self regulating

nVent RAYCHEM IceStop self-regulating heat trace cables automatically adjust their power output to compensate for temperature changes. They have a heating element that consists of a continuous core of conductive polymer extruded between two copper bus wires. As current flows through the core, the IceStop heat trace cable regulates its own heat output in response to ambient conditions—eliminating hot spots and resulting in better temperature control and roof and gutter protection.

Roof Ice Melt ( RIM / RIM2 ) System

RIM system consists of metallic panels that embed self-regulating heat tracing cable to provide high power output and an aesthetically pleasing roof de-icing solution. The panels are offered in different metal types including copper, zinc, Corten®, or Kynar® painted aluminum. Aluminum panels come in 31 different colors to match the color of roof material. The RIM system includes panels specifically designed for eaves, valleys, channels, rakes and flat roof sections as shown below:
