A device used to determine the appropriate diameter for conduits channeling water away from a rooftop surface. This tool typically considers factors such as rainfall intensity, roof area, and drainage system slope to arrive at a suitable measurement. For example, a building with a large roof in an area experiencing heavy rainfall will necessitate a wider pipe diameter than a smaller roof in a drier climate.
Employing such a device is crucial for ensuring efficient stormwater management and preventing structural damage caused by water accumulation. Adequate drainage design safeguards against roof leaks, ponding, and potential collapses. Historically, estimations relied on simpler, less precise methods. Modern calculators, however, provide enhanced accuracy, leading to more reliable and cost-effective drainage solutions.
