There are two types of roof tiles – overlap and sliding tiles.
• Sliding tiles have only one side lock and allow the spacing to be adjusted by the size of the overlap. This allows you to adjust the length of the covering to the specific size of the rafters. Sliding tiles are recommended for use in roof renovation, in which the dimensions of the roof truss cannot be changed. Sliding tiles should be laid with an overlap of the width depending on the slope of the roof slope. Wrong selection of the plant size causes the risk of easy penetration of the cover by rain and snow. This is especially true for low-pitched roofs.
• Overlap tiles have special side and front zippers, which regulate the phenomenon of the so-called. blowing and draining water from precipitation. Overlapping tiles are more difficult to place on a finished roof than sliding tiles, because they require adjusting the length of the rafters to the multiple of the batten spacing for a specific tile model.
