What are the key components of a roof drain?

The correct answer highlights the essential elements that make up a roof drain, which includes the strainer, flashing ring, and drain body.

The strainer is crucial as it prevents debris from entering the drainage system, ensuring that the water can flow freely without blockage. It also plays a role in maintaining the system by keeping larger particles out, thus reducing the likelihood of clogs.

The flashing ring is important for waterproofing, as it integrates the drainage system with the roofing material to prevent leaks. It establishes a seal around the drain, helping to keep water from seeping through the roof where the drain is located.

The drain body serves as the main channel for directing the collected rainwater away from the roof and into the building’s drainage system. It collects the water that passes through the strainer and transports it efficiently.

Overall, these components work together to ensure effective water management on a roof, preventing water accumulation that could lead to leaks or structural damage.
