COMPARATIVO TÉCNICO-ECONÔMICO DE TELHADOS RESIDENCIAIS: Telhado colonial, telhado metálico e telhado verde

Abstract

This paper presents a technical-economic comparison between three types of roofing used in residences: colonial, metallic and green roofs. This comparison is important because roofing costs can reach up to 10% of a project's total cost. The purpose of this paper is to determine from actual data of three similar works which of the roof types mentioned is the most economical for a residence. The accompanying works were carried out in the city of Campanha - MG, in 2016 and 2017, in the same allotment and have similar built-up areas and finishes. The differential of this research is that the calculated values take into consideration not only the cost of tiles and structures, but all the manpower, fittings and finishes needed to build the entire roof and rainwater catchment system. The analysis showed that the metallic roof was the most economical among the analyzed ones, but changes of substitution of noble wood and tiles by more common ones are suggested, making the colonial roof the most economical one.
