Valleys

Lay heating cable up to two-thirds of the length of each valley, a

minimum of 91cm (3ft.), and return to form a double run of heating

cable in the gutter. Extend the cable higher if the heated area of

your house below your roof is farther up the valley.

(D): Valleys length

Cable Length required for valleys: (C)

x (D) x (2/3)

Attach the heating

cable up and down

the valley and keep

two parallel lines at

least 5cm (2in). away.

Dormers For a problem dormer area, the cable should be arranged up and

Cable Length required for dormer:

Distance around dormer

Attach the cable with the clips

in every 91cm (3ft) when the

cable is running vertically

around a dormer.

Gutter and

Downspout

1. The heating cable needs to be installed along the treated

roofline through the gutter. Install the cable down into and back

up the inside of any downspouts. If there is a downspout at the

end of the roofline, you need only route the cable down the

inside of the downspout but not back up.

2. If your icing problems are only in the gutter, the cable would be

routed only in the gutter and downspouts using a “double run”

Fasten the gutter

cable to the

bottom of each

drip loop by

using a spacer.

Secure the cable

in the gutter, but

keep it off the
