What is the minimum pitch for concrete roof tiles?

Maximum slope of tile roof

Pitched roof with an average slope of 30%, consisting of: slope formation: hollow tongue and groove ceramic board, to be covered, 50x20x3 cm on lightened partitions of 100 cm average height; covering: curved ceramic tile, red color, 40x19x16 cm; received with cement mortar, industrial, M-2.5.

The surface of the resistant base will be checked to ensure that it is uniform and flat, clean and free of debris.  It will have been previously solved its encounter with the passage of facilities and with the ventilation and smoke outlet openings.

Cleaning of the slab soffit.  Laying out and layout of the filing, filing holes, junctions and joints.  Formation of perimeter partitions with ceramic pieces.  Formation of lightened partitions.  Laying of the finishing of the lightened partition walls to receive the board.  Placement of the paper strips on the lightened partitions.  Placement of the ceramic pieces that form the board.  Pouring, spreading and levelling of the regularization mortar layer.  Placement of the tiles received with mortar.  Execution of ridge tiles, eaves, eaves and free edges.

How to calculate the orderly slope of the roof? What should be the slope of the roof of a well-made home? With the modern architectural trends of flat roofs with wide edges and straight lines, it would seem that pitched roofs and some covered with tiles, have gone out of fashion in the eyes of planners and homeowners, however, pitched roofs with the corresponding angle have their charm and in some types of climate are a necessity. When to opt for a pitched roof with a vertical line? In this idea book we are going to share some details on how to calculate the slope that a roof should have for it to work properly, which is what professional designers always do when defining architectural details.Take note on how to calculate the neat slope of a house roof.Some of the main factors that you have to take into account when deciding the style and formation that your roof will take, you need to take into account if it is a pitched facade, or you want to combine different types of prefabricated roofs. Whatever the case may be, get an affordable roof for your home that fits your style and the vision you want for your home. Let’s get to it!

Maximum slope of a roof

In order to guarantee the watertightness of the tiles on a pitched roof, it is necessary to establish minimum slopes based on a previous analysis of both the location of the project and its degree of exposure.

With the regulations in hand, values are established for the different areas of the geography, as well as a classification of protected, normal or exposed exposure. These data, together with the length of the roof, from eaves to ridge, will set the minimum slope values for each scenario.

This procedure is given by the water evacuation capacity of each type of tile, i.e., a corrugated profile tile will always evacuate more water than an alicantina or flat format tile.

Another point to take into account is that the longer the roof, the greater the amount of water to be evacuated, which, together with the level of exposure and rainfall levels, will result in higher slopes as the distance from eaves to ridge increases, as well as if the project is more exposed or in an area with a high amount of rainfall.

Sloping roof

Thanks for the two answers, but the problem is not the waterproofing by rain or not, but in places of snow the roofs must have a sufficient slope to evacuate the same, and there is no risk that it accumulates, and therefore supporting excessive weight with risk of collapse.

In the case of snowy places, roofs must have a sufficient slope to evacuate the snow, and there is no risk of it accumulating, and therefore supporting excessive weight with risk of collapse.

As of today the standard is the CTE and this does not require any slope for snow accumulation issues, in fact there is a section that says what actions must be considered on flat roofs due to the weight of the snow. Also in the previous NBE AE there were these considerations, then allowed slope = 0.

And also without asphalt sheeting, they use a kind of gravel or clay (I do not remember the name but it may be sod?) that does not let any drop of water through, very curious indeed. Of course I am referring to traditional construction.
