ABSTRACT: The search for more effective, cheaper and more eco-friendly processes is an issue that is becoming more common nowadays. This study has the goal of comparing two roof drainage system methods: Conventional Method, regulated by the NBR 10844 (ABNT, 1989), where the flow in vertical and horizontal pipes goes partially full; and Siphonic Method, regulated by the BS 8490 (BSI, 2007), where the flow goes on a full bore state, aiming to evaluate their main methodological differences and similarities, performing a financial analysis for both methods. To obtain the desired results, 10 industrial storage units had their roof drainage system designed with different roof areas between them. The financial viability between the methods was calculated by estimating materials and labor costs for the scenarios, obtaining a graphic relation between cost and roof area. It was considered brands available in the national market for both roof drainage systems. After performing the calculations and comparing the values between the designs, it was noted that for a roof area greater than 2935,57 m², the Siphonic System is more financially viable compared to the Conventional System.
