These are also called deicing cables and they can be.
Sudden release of snow off a rooftop is unpredictable.
The second most common mistake is to miscalculate the load by using ground snow rather than roof snow in calculation.
To try to resist that force when it is not known is a crapshoot that often results with failure.
