Running a communications cable over a roof with a 4:12 slope, what is the minimum distance the cable can be from the roof top?

• A. 2 feet
• B. 4 feet
• C. 5 feet
• D. 3 feet

Answer: (D)

Maintaining a safe clearance from the roof surface when running a communications cable over a pitched roof is about protecting the cable and ensuring safe maintenance, not about the roof’s steepness. The slope (4:12) describes how steep the roof is, but it doesn’t change the minimum clearance required. The standard minimum distance from the roof top is three feet, so the cable should be kept at least three feet away from the roof surface. This keeps the cable clear of shingles and weather effects and provides room for inspection and any work on the roof. Distances of two feet are too close to the roof, while four or five feet go beyond the required minimum without added benefit in this context.
