Iridak Long tile is a modification of the Clay tile roof. Observations of the Clay tiled roofs showed that it imposed its weight in addition to other imposed loads directly onto its structural carcassing which tend to fail when there is a slight defect in the carcassing material. Another aspect is the discoloration of the clay tiles which gives an unpleasant look overtime. This gave birth to the Long tile which uses the Zincalume sheets in the formation of the design with the tile appearance. It has an advantage of being lightweight and has a wider coverage than the clay tiles which makes it economical in terms of cost. The only disadvantage is that, the structural carcassing has to have close purlin members to make the sheet sit well. It has an effective coverage area of 900mm and a depth of 28mm making it difficult to distinguish between the long tile and the clay tile from a distance
