Roof & Gutter De-icing
Note: Route and secure the heating cable to avoid possible mechanical
damage, such as from ladders, etc.
General requirements for roof & gutter de-icing:
• FrostGuard is designed to remove melt water, not accumu-
lated snow.
• FrostGuard heating cable will not keep snow or ice from fall-
ing off the roof. Snow fences or snow guards should be used
to eliminate snow movement. For the names of manufactur-
ers of snow guards or snow fences, contact nVent
at [phone].
• FrostGuard heating cables may be used on:
- Roofs made from all types of standard roong materials,
including shake, shingle, rubber, tar, wood, metal,
and plastic.
- Gutters made from standard materials, including metal and
plastic.
- Downspouts made from standard materials, including metal
and plastic.
• Do not use an extension cord.
• Do not install the heating cable underneath any roof covering
for roof and gutter de-icing.
• Install only in accessible locations; do not install behind walls
or where the cable would be hidden.
• Do not run the heating cable through walls, ceilings, or oors.
• Connect only to ground-fault protected outlets that have been
installed in accordance with all prevailing national and local
codes and standards and are protected from rain and other
water.
Electrical codes
Article 426 of the National Electrical Code (NEC), and Part 1,
Section 62 of the Canadian Electrical Code (CEC), govern the
installation of FrostGuard heating cables for roof and gutter de-
icing and must be followed.
Important: For the nVent warranty to be valid, you must comply
with all the requirements outlined in these guidelines.
All design information provided here is based on a “standard”
shake or shingle roof application. For any other application or
method of installation, consult nVent at [phone].
