What does the term "Roof Drainage Systems" include?

The term "Roof Drainage Systems" encompasses components that are primarily designed to manage the flow of water that collects on a roof. This system is crucial in preventing water damage to the structure and ensuring the proper dispersal of rainwater away from the building. Gutters, downspouts, and splash blocks work together in this system: gutters collect the rainwater from the roof's edge, downspouts channel the water downward to the ground level, and splash blocks direct the water away from the foundation of the home.

In contrast, the other options refer to different areas of a home. Electrical systems and wiring pertain to the power supply and distribution throughout a building, heating and cooling systems relate to climate control, and interior plumbing components involve the plumbing infrastructure within the home for water supply and waste removal. All of these systems play vital roles in a home but do not relate to managing roof runoff or drainage, which is the specific focus of roof drainage systems.
