Overhangs are common in most house designs providing protection against both wind and rain. Calculate the length of a rafter from the roof slope ratio of inches per foot and a building width measurement. If you add an eaves overhang dimension then the amount the rafter sticks passed the wall will be added to the rafter length. Measure the length of the gutter where you want to stretch the cable then figure out how far to the nearest foot the eave extends beyond the exterior wall of the home.

Pitch is the incline of the roof represented as the ratio of rise to the span twice the run. The rafter member will be longer. Thus a moderate 6 in 12 roof pitch means that the roof rises 6 inches vertically for every 12. Drip edge flashing.
