How should slate tiles be installed along the ridge?

The proper installation of slate tiles along the ridge is critical for ensuring the longevity and effectiveness of the roofing system. Setting the tiles in sealant or asphalt cement provides an essential barrier against water infiltration. Ridge tiles are particularly vulnerable to leaks due to their location at the apex of the roof where water runoff converges. By using sealant or asphalt cement, it helps to create a watertight seal that prevents moisture from seeping underneath the tiles, which could lead to damage, mold growth, or structural issues over time.

Using sealant not only enhances the waterproofing of the installation but also gives an added layer of security, especially in areas prone to heavy winds or storms. This method is superior to simply nailing the tiles or leaving them loose, as these alternatives may not provide the necessary protection against the elements, potentially compromising the roof's integrity. Proper overlap is also crucial in this context, ensuring that each tile effectively channels water off the roof rather than allowing it to pool or seep through.
