Correct slopes in pitched roofs
The slope in a pitched roof is not merely a formal decision. It determines water drainage, structural behavior, material durability, and the overall aging of the system.
In traditional clay tile systems, the recommended minimum slope typically ranges between 25% and 35%, depending on the construction system, the roof span, and the local climatic conditions.
An insufficient slope leads to moisture accumulation, leaks, and premature deterioration of the substrate. An excessive slope, on the other hand, can alter the proportion of the volume and the architectural reading of the building.
Well-executed technique is always silent.
The right balance lies in the relationship between material, structure, and proportion. The roof should not impose itself visually, but rather complete the overall order of the project.
Understanding these principles allows for the design of roofs that perform correctly and age with dignity.
