Solar panels on tile roofs: the 5 most common mistakes

Tile roofs require careful mounting design because the roof covering is fragile and every fixing point affects waterproofing. The most common mistakes are fixing into weak surfaces, skipping flashing details, and ignoring thermal movement.

A correct installation starts with rafter detection and continues with sealed hooks, cable routing, and load checks.

Quality control after installation is as important as the mounting itself: water paths, cable bends, and panel clamps must all be checked.
