What is double lap tiling?

Double lap tiling is a roofing and siding technique where each tile overlaps two tiles beneath it, creating a more secure and weather-resistant installation. This method helps to prevent water infiltration and provides additional insulation. Commonly used with materials like slate or shingles, double lap tiling enhances durability and can improve the aesthetic appeal of a building. It is particularly effective in areas with heavy rainfall or harsh weather conditions.
