A tool for determining the proper incline of an exterior elevated platform typically attached to a building provides essential information for water runoff and structural integrity. This incline, expressed as a ratio or percentage, is crucial for preventing ponding, which can lead to material degradation, and ensures safe and comfortable usage. For instance, a ratio of 1:48 represents one unit of vertical drop for every 48 units of horizontal distance.
Correct inclination is fundamental for long-term performance and safety. Historically, builders relied on simpler methods like the rise-over-run calculation. Modern tools offer greater precision and often incorporate features to account for local building codes and specific material requirements, leading to improved designs and reduced construction errors. This meticulous approach also contributes to enhanced accessibility and compliance with regulations.
