What is the maximum rise for flat profile tiles?

The maximum rise for flat profile tiles is 1/2-inch, which helps ensure proper water drainage and a secure fit. Flat profile tiles are designed to be installed closely together, minimizing gaps between them that could lead to water penetration or leaks. A rise larger than 1/2-inch could potentially compromise the integrity of the roof system, allowing water to pool or creating an uneven surface that may not effectively shed water. This guideline is important for maintaining the longevity and effectiveness of the roofing system, making 1/2-inch the recommended maximum rise for flat profile tiles.
