Definition & Meaning of "roof curb"

What is a "roof curb"?

A roof curb is a raised structure or frame located at the edge of a roof, designed to provide support for equipment such as air conditioning units, vents, or skylights. The curb provides a stable base for the equipment and helps to create a weather-tight seal, preventing water from entering the building. Roof curbs are usually made from durable materials like metal or wood and are designed to withstand the elements. They also help ensure proper drainage by directing water away from the opening, which is important for maintaining the integrity of the roof and the building as a whole.
