Installation is where roofing success is decided. A well-made tile installed wrong will leak, warp, and fail faster than a mid-grade tile installed correctly. The pattern is consistent across job sites: the material gets blamed, but the root cause is usually in the fastening, the spacing, or the details at edges and transitions.

This guide covers the five installation errors that generate the most callbacks — and how to prevent each one before the crew leaves the site.

Installation quality is not about skill level alone — it's about consistent process. When the crew follows the same sequence, uses the same accessories, and checks the same points on every project, the callback rate drops predictably.
