clay tiles on curved roof




Initially we planned to put a sheet metal covering on our roof because that is the conventional wisdom for a curved roof. Everybody we spoke to in the planning phase has agreed that such a roof can only be covered with sheet metal or shindra. But critical thinking has proven once again, well critical, and it turned out that one can easily and without much trouble cover a curved roof with clay roof tiles. The smallest radius for our roof is approximately 10m and roof tiles are usually 30-36 cm long. that means that on the most critical, most curved part of our roof a tile will have a declination of just 4,5mm from the ideal position it would take on a flat roof. Because I find that to be insignificant, the only other problem with our roof in regard to covering it with clay tiles is that on the upper section, it does not match the prescribed minimal descent by the manufacturers (15 degree). My intention is to build a watertight underconstruction, ignore the recommendations and go with a slope of only 9 degree on the uppermost part.
