Box Gutters & Valleys in Sydney
Box gutter and valley repair in Sydney: the ceiling stain only shows after a real downpour, never in light rain. That points at a gutter inside the roof line backing up, not a hole in the roof.

Questions and answers
A box gutter copes with drizzle even when the outlet is half blocked, but a downpour fills it faster than it drains. Once the water rises past the back of the gutter it goes into the roof.
No. The iron sits under the tiles on both sides, so the tiles have to come off and go back on. Anything done from the top only covers the rust.
A sump is a deeper box at the outlet of a box gutter that gives water a head of pressure to push down the downpipe. Without one, the outlet can only take a trickle, and the gutter backs up in a storm.
If the metal is sound and the problem is a blocked outlet or one failed join, yes. If it is rusted, laid flat or held together with silicone, replacing it is the repair that lasts.
Much longer if the valley is kept clear of leaf, because the leaf dam is what rusts them out. We point out any overhanging trees that will keep filling it.
The length, the number of corners, access and the state of the timber underneath all move the price. You see photos and a written price before any roofing is lifted.
