Most of it is a repair, not a re-roof
Concrete tile of that era routinely outlasts the house. When one of those roofs leaks,
what has usually failed is the mortar and the valleys, and both are fixable without
touching the rest of the roof. A box gutter or a parapet flashing at the other end of
the run is the same story: it presents as a ceiling leak, it feels catastrophic, and
it is still a repair.
That matters because the gap between the two answers is large. Re-pointing ridge
capping starts at $800. A re-roof is a different order of money, and the only thing
standing between being quoted one and needing the other is somebody getting on the
roof and photographing what is actually there.
So that is what the free inspection is. Ladder up, walk it, photograph every valley,
ridge, flashing and gutter, and put what we found in writing before anyone talks about
price. You keep the photos either way.
