C. Heating Cable Layout - Roof Overhang Only . . .
1. Refer to the RGS Design Guide to determine appropriate
heating cable lengths required, as well as spacing pitch
required for various overhang distances and roof types.
2. The attachment clips should be anchored to the roof/fascia
with fasteners or adhesive suited for the roof and the
weather. A waterproofing sealant should be used wherever
screws penetrate the roof or fascia.
3. Where large roof areas will be present above the heating
cable a snow fence should be installed to prevent damage to
the cable from sliding snow and ice.

D. Heating Cable Layout - Gutter and Downspouts Only . . .
1. Refer to the RGS Design Guide to determine appropriate
heating cable lengths required for gutters and downspouts.
2. The attachment clips should be anchored to the fascia/
gutter edge with fasteners or adhesive suited for the roof
and the weather. A waterproofing sealant should be used
wherever screws penetrate the gutter or fascia.
3. Heating cable should be attached to the bottom of the
gutter with aluminum tape. Be sure the bottom surface of
the gutter is clean to promote maximum adhesion of the
tape. Heating cable in the downspouts should not extend
past the downspout opening to prevent vandalism.
4. Protect heating cable from sharp edges of gutter and
downspouts.
E. Heating Cable Layout - Roof Overhang Plus Gutter and
Downspouts . . .
1. Refer to the RGS Design Guide to determine appropriate
heating cable lengths required.
2. The attachment methods outlined in sections C and D
would apply to installing heating cable on both roof
overhang and gutter/downspout areas.
