The Honest Recommendation Was Replacement, Not Repair
We could have patched it. On a building with this many separate problem areas, patching would have meant returning repeatedly, chasing the next leak each time, and spending real money without ever getting ahead of it.
The tile was too fragile to work with reliably — every repair risked creating new breakage nearby. The underlayment was compromised in multiple places, not one. And the leaks were not isolated to a single failure point, which usually means the system as a whole has reached the end of its life rather than one part of it failing early.
So we told them straight: the money made more sense spent once on a replacement than repeatedly on repairs that would not hold.
The work itself: full tile removal, deck inspection across the entire roof, a complete new underlayment system installed across the full surface, and new tile set with proper fastening and detail at the hips, ridges, and valleys.
